Introduction

A ketogenic diet is any diet extremely low on carbohydrates, usually below 30 grams a day, which forces the body to take the same steps as in starvation, most importantly that of replacing carbohydrates with fat as the main fuel of the human body. These diets are extreme when compared to the nutrition recommendations in vogue, but the fears surrounding what a diet rich in fats and protein could do to us have proven largely ungrounded (as a sideline, diets rich in fats AND carbohydrates are a whole different story and should not be confused with low-carbohydrate high-fat diets as the biochemistry behind them is radically different). Much of the data on the safety of this diet comes from the clinical use of ketogenic diets to control childhood epilepsy where children are kept for years on this kind of diet with little side-effects. Nevertheless, it should be recognized that the amount of long-term research data is still scant. The debate surrounding whether our stone age ancestors lived mostly on a ketogenic diet or not (which would point to us still being biologically primed for that kind of fare) is still out in the open, but the fact remains that there are good examples of people, most notably the Eskimoes and Northern Europeans during the harsh winter months, that subsided mostly on a fare of meat and fat while having very low incidence of cardiovascular diseases. Be that as it may, this overview of a particular ketogenic diet is not geared towards defending the diet nor towards proving how this is the only way to lose fat efficiently (it’s not), but rather to present how the diet works biochemically and how it is done in practice. Towards that end, there is no attempt to fully reference the claims made in this article; those who want to examine the research behind ketogenic diets should start by reading the fully referenced The Ketogenic Diet - A Complete Guide for the Dieter and Practitioner by Lyle McDonald, without doubt THE defining work on the topic of using the diet for athletes; every serious ketogenic dieter should own a copy. For information on how the diet is used in treating childhood epilepsy, see The Epilepsy Diet Treatment: An Introduction to the Ketogenic Diet by Dr. Freeman et al. and the factual movie First Do No Harm.

The first part of this article attempts to explain the biochemistry behind how ketogenic diets work without previous knowledge of fuel metabolism. Doing so, the case is presented in an order somewhat different from that found in many textbooks (as a case in point, insulin is left to the end of the discussion). The text is kept as brief as possible, but central concepts have external links, mostly to Wikipedia for laziness’ sake, for those readers who would like to face the biochemical nitty-gritties. There is also a cursory link section at the end of this article. Still, nothing beats getting a good introductory biochemistry book if you want to see the big picture. Starvation and fuel metabolism have been well-studied and the biochemistry behind a ketogenic diet is largely uncontroversial. The second part of the article distances itself from the theory and shows how to set up a modified ketogenic diet with carb loading to meet the needs of athletes involved in strenous anaerobic activities such as heavy weight training.

This article draws heavily on a 1997 article I wrote in Swedish on the cyclical ketogenic diet based on the lively discussions on the lowcarb-l mail list (you can find my posts via the archives search engine if you enter Lindqvist Kristoffer J as author), Mauro DiPasquale’s Anabolic Diet manual and video from 1995, and the bits and pieces of information available on the web at the time (the most important being the BodyOpus archives by Lyle McDonald). Ultimately, much of the credit for pulling together the research and polishing up the diet belongs to Lyle McDonald and Jeffrey Krabbe, who were the leading men when this variation of the diet was being formulated on the lowcarb-l list. In the end, Krabbe pulled out of their joint book project leaving McDonald as the sole author of the aformentioned The Ketogenic Diet which refined the theory of the earlier works on cyclical ketogenic diets, notably The Anabolic Diet by Dr. Mauro DiPasquale (actually, as we will see later, this diet is not strictly speaking ketogenic) and BodyOpus by Dan Duchaine. This article has been checked and revised against the first edition of The Ketogenic Diet (1998) together with a close reading of some of the biochemistry books in my bookshelf. To my knowledge not much has changed since the late 1990s, but I naturally welcome any updates or corrections you may have (comments can be left at the end of the article). My own experience with this diet goes back to 1995 (two months), 1996-1997 (lived on it for well over a year with only a few carb weeks here and there) and 2002 (six-weeks) in conjunction with bodybuilding style training. As this article goes to press, I am on my sixth week of the diet for the purpose of dropping fat weight off for a virtual powerlifting meet. Before we roll, let me emphasize that I take no responsibility for anyone following any advice found in this article. Curtains up!

Part I: The theory behind ketogenic diets

A CRASH course on the biochemistry behind starvation and ketogenic diets

The human body needs energy to function. Ultimately, the source of all energy (calories) is the food you eat - specifically the digestable carbohydrates (carbs for short), proteins and fats your meals contain. The digestive tract extracts these nutrients from the food that passes through it and splits them into smaller fragments usable to the cells before they can enter the bloodstream; carbohydrates are split into simple sugars (mainly glucose), protein into amino acids, and fats into glycerol and fatty acids. Out of these, humans can extract 4 calories from each gram of protein, 4 calories from each gram of carbs and 9 calories from each gram of fat [note that this article uses calories in the colloquial sense; technically, we should say kilogram calories (kcal)].

The problem is, these fuels enter the body discontinously as you eat every few hours, yet the body continously needs energy to function. It is not physically possible for the body to keep all the nutrients it has floating around in the bloodstream, hence it needs to warehouse the excess somewhere where it is accessable between meals and during sudden rises in energy demand (such as during strenous exercise). Glucose is stored as glycogen in the muscles and liver. Fatty acids end up mainly as triglycerides (also called triacylglycerols) together with glycerol (specifically, one molecule of glycerol binds to three molecules of fatty acids) in the fat cells of adipose tissue located under the skin and around the internal organs, where it acts as insulation and padding, although some triglycerides are also present in all cells. In contrast, amino acids cannot be stored beyond a small pool in the bloodstream, and are used immediately for a variety of tasks - including structural repair of muscle tissue and acting as catalysts, carriers and receptors in various processes. When there are more amino acids available than can be used, the excess is converted into glucose or fatty acids as needed. Similarly, once the glycogen stores are full, any excess glucose is converted into fatty acids for storage. In a nutshell, the triglyceride deposits will readily absorb any excess of amino acids or glucose and can theoretically grow as large as the body can carry without collapsing. In the human body, fat is the ultimate form of stored energy. Fats carry more than double the calories per gram than glucose (i.e., 9 calories per gram for fats vs. 4 calories for glucose) and does not need to bind to water to be stored, unlike glucose where every gram of glucose binds to approximately 2.7 grams of water to form glycogen. This means that stored fats yield 9 calories per gram whereas glycogen only yields 1.33 calories per gram. To give you some perspective, if you stored the energy found in 10 lbs/5 kg of fat as glycogen it would amount to 67.5 lb/31 kg. In practice, the energy of all stored glycogen never exceeds 2,000 calories (the average under normal conditions being less than 1,000 calories) whereas someone carrying 33 lbs/15 kg of stored fat (eg. a 150 lb/68 kg man with 22% bodyfat) would have 135,000 calories worth of energy from fat alone!

Most human tissue prefers glucose as fuel over fatty acids, but some tissue (including the brain and Type II muscle fibers) are unable to use fatty acids for energy at all. When glucose is available it is always the preferential fuel, with fat deposits functioning as a large store of backup energy for those times when food might not be available in sufficient quantities. Yet, glycogen stores are too small to last for more than a day unless refilled. Furthermore, glucose can only enter muscle, not exit back into the bloodstream. Muscle glycogen can only be used to fuel the muscle it is stored in, thus leaving liver glycogen as the sole source of readily available stored glucose for all other tissue. There is some variability based on meal size and composition, but as a general rule of thumb the liver needs to start converting its glycogen back to glucose and eject it into the bloodstream (called glycogenolysis) within four hours of a carb containing meal. Unless more carbs are ingested, only the tissue totally dependent on glucose will be able to absorb available glucose with other tissue having to turn to breaking down fatty acids for energy. As glucose levels in the blood continues to fall, the body initially tries to counter this by converting other available fuels to glucose. In animals, fatty acids cannot be converted into glucose, but glycerol can be. However, glycerol alone is not enough which causes an increasing amount of amino acids (mainly alanine and glutamine) to be converted into glucose (gluconeogenesis) in the liver, and to a lesser extent in the kidney, which practically means that muscle tissue is broken down for energy.

Within 16 hours after the last carb containing meal, liver glycogen is almost depleted and blood glucose levels adequate to fuel the brain and other glucose dependent tissue can no longer be maintained solely by breaking down amino acids. At this point, the brain would slowly cease functioning and go into coma if there would be no alternate way of producing the fuel it needs. Luckily, the liver has one more trick up its sleeve called ketogenesis. Even in the presence of carbohydrates, the liver is always producing something called ketones out of free fatty acids, although in too minute amounts for them to be of much physiological consequence. However, once liver glycogen is depleted, ketogenesis is rapidly increased. As it turns out, most tissue in the body will happily use ketones for energy when glucose is not available, including those unable to use fatty acids; thus, glucose and ketones are both nearly universally accepted fuels for the whole body whereas several kinds of tissue can’t work with fatty acids. As the brain gradually adapts to using ketones as fuel over about three weeks of ketosis (the state where the body uses ketones as its main fuel instead of glucose) it will happily replace up to 75% of its glucose requirements with ketones. As glucose requirements are drastically reduced, the amount of amino acids that need to be converted into glucose also decreases sharply. Thus, like glucose, ketones have a protein sparing effect. If protein would continue to be broken down at the rate seen before the body has fully adapted to ketosis, a starving individual would quickly run out of muscle mass and die (being unable to move due to muscle athropy long before that); thanks to the lowered conversion rates, it is the size of the fat deposits that matters thus allowing an average individual to survive for months. Even when in ketosis, the brain still requires roughly 40 grams of glucose per day, but this amount is easily met by conversion of amino acids and glycerol to glucose. As a sideline, the initial breaking down of muscle tissue also serves as an important adaptation to starvation as less muscle mass means that less calories are needed to sustain the body.

In sum, the state of ketosis appears to essentially be a survival mechanism that ensures that the brain gets what it needs when glucose is sparse (to think of a way to obtain food) by producing an alternative fuel source, ketones, out of our largest energy deposits (fat) to appease the other types of tissue normally dependent on glucose. Ketosis also has the effect of blunting hunger which could easily stand in the way of hunting for food. Thanks to ketosis, extremely obese persons can survive for over a year with no food as long as water and the various mineral/vitamin requirements are met (this has been done clinically to diet down people who face urgent health issue due to their extreme weight at the cost of a large loss of lean body mass - do NOT try this at home).

A ketogenic diet mimics starvation by lowering carbohydrates, thus causing ketosis. The main difference is that as adequate protein is eaten, the body will use that to produce glucose instead of having to break down muscle tissue. Furthermore, whereas starvation sucks the minerals it needs from wherever it can find it in the body (such as in the bone structure), a ketogenic diet again supplies them through diet and supplementation. On paper this sounds like the ultimate diet for fat loss. Fat is the main source of fuel and, unlike what often happens on a carbohydrate based diet when carbs are too low or not ingested frequently enough, protein theoretically never needs to be broken into glucose as long as the body doesn’t run out of fat (very unlikely) and protein is eaten in enough quantities. As fats take longer to digest and ketosis blunts hunger, the sensation of hunger is much lower than on a carbohydrate based diet despite the volume of food being much lower on a ketogenic diet. In ketosis the body is a fat burning machine, when not in ketosis (as on a traditional carbohydrate based diet) the body is primarily a glucose burning machine supplemented by some fat if calories are below maintenance.

The case for carbohydrates

Properly executed, ketogenic diets would appear to indeed save lean body mass better than traditional carbohydrate diets. As we have seen, the body does not actually need carbs to function BUT the absence of carbs does come at a price for a weight training individual.

To understand the role of carbohydrates we need to say a few words on HOW the body regulates blood glucose levels. This happens with the help of two hormones. When blood sugar levels rise, such as after a meal, it causes the pancreas to secrete a hormone called insulin which stimulates the storage of glucose as glycogen (and fat once the glycogen stores are filled). Insulin also stimulates protein synthesis and pushes amino acids into the muscle cells (or, again, fat stores if no aminos are needed for repair or other functions). Conversely, as blood glucose levels drop so does insulin levels. This, in turn, causes another hormone, glucagon, to be secreted by the pancreas. Glucagon does the opposite thing as insulin, namely stimulates the release of stored fuels (liver glycogen, triglyceride stores and protein breakdown) to the degree necessary to restore normal blood sugar levels. Thus, insulin is an anabolic (”building up”) hormone whereas glucagon is a catabolic hormone (”breaking down”). Very plainly put, what determines whether insulin or glucagon predominates is simply the amount of glucose in the blood (blood sugar levels). Now, carbs, protein and fats are all converted to glucose to some degree and so all affect blood sugar levels, but to different degrees. Basically, carbohydrates will be 100% converted to glucose, protein 54% and fat 10% (from the glycerol part) regardless of whether the body is in ketosis or not. This means that carbohydrates have the strongest influence on blood sugar levels by causing a much larger insulin response than protein or fats. Put simplistically, a carbohydrate based diet will cause insulin to predominate thus priming the body for repair and fuel storage whereas a diet low in carbohydrates will cause glucagon to dominate thus promoting the breakdown of stored fuels while inhibiting muscle repair. It should be fairly obvious where this is going: the benefit of a low carbohydrate diet, specifically a ketogenic diet, is the stimulation of fat breakdown via high glucagon levels, but the low levels of insulin makes muscle repair suboptimal compared to a carbohydrate based diet. What happens on a carbohydrate diet is the opposite, namely that muscle repair is stimulated but fat loss inhibited (this is one of the reasons why it is so hard to naturally gain muscle mass without also gaining fat as insulin promotes both processes in the body). Blood sugar levels are essentially identical on carbohydrate diets and ketogenic diets, but the hormonal environment that ensures this is much different.

Secondly, type II muscle fibers require glucose to function optimally. Type II muscle fibers are the so-called white or fast twitch muscle fibers that are primarily used during anaerobic activities, such as heavy weight training and sprinting. Recall that the depletion of liver glycogen is what ultimately causes ketosis. Even when in ketosis, the type II fibers will receive the glucose it needs to work optimally for as long as the muscle glycogen stores are not depleted. Once the stores are empty, such as after a single workout of sufficient volume, the muscle has to rely on fatty acids and amino acids broken down into glucose thus causing performance to drop.

As you can see, a long-term ketogenic diet (such as Atkins) comes at a heavy price for anyone training with weights or involved in anaerobic activities. This is why strength athletes ultimately need carbs to reach peak performance and why ketogenic diets geared towards athletes generally include well-timed carbs in some capacity; carbs are usually eaten either around workouts (Targeted Ketogenic Diets, TKDs) or during 24 to 48 hours once a week or less (Cyclical Ketogenic Diets, CKDs). The carbohydrates will disrupt ketosis, but will cause a brief anabolic insulin spike that replenishes muscle glycogen and promotes muscle repair. When well-timed, the trainee quickly returns to ketosis (in fact, on TKDs ketosis is not necessarily even disrupted). The rest of this article will focus on CKDs, which arguably are superior to TKDs for serious lifters.

On a CKD, glycogen stores are first depleted by weight training and then refilled all at once using a high carbohydrate intake that will take the dieter temporarily out of ketosis before the low-carbohydrate fare is resumed - this is very similar to the classical carbohydrate loading model employed by marathon runners which causes muscle glycogen stores to become supercompensated (as in much bigger than normal, on the order of 150% following a 36 hour carb-load, provided enough carbs are ingested). Glycogen supercompensation will only occur if the muscle glycogen is depleted enough, hence it is imperative that enough muscular work (weight training) is performed before the carb-load (more details to follow). The reason a 24-48 hour carb load is used is that only so much glycogen can be resynthetised per hour. The amount of carbohydrates that must be ingested is large, around 4.5 grams of carbs per pound/10 grams of carbs per kilogram LBM for the first 24 hours, but with muscle glycogen being depleted, the risk of fat gain is minimal until the deposits are filled to the brink. This is a big boon psychologically, as at least twice the amount of calories are ingested for the first 24 hours compared to the low-carb days and all the carbohydrate-dense foods that are totally off-limit during the low-calorie low-carb days can now be eaten (even candy is desirable at the beginning of the carb load). Physiologically, the brief spike in calories also shakes up the metabolism thus preventing the body from going into the fuel sparing mode which often happens when calories are kept below maintenance levels for long periods of time.

In practice, these modifications have proven successful means of retaining performance in the gym while effectively sparing muscle tissue and reaping the benefits of ketosis, BUT the fact remains: the constant presence of insulin on a carbohydrate containing diet is superior for building lean body mass everything else being equal. In a nutshell: a well-orchestrated ketogenic diet is likely to be superior for shedding fat while retaining as much muscle mass as naturally possible, but it is not the way to huge gains in muscle or strength. This is why it is common to cycle ketogenic diets for fat loss with carbohydrate based diets to build muscle with some gains in fat. Some athletes might find the ketogenic a valuable aid in those circumstances where some strength or muscle gains are desired while keeping bodyfat gains to a minimum.

How much fat, protein and carbs should one eat on the low-carb days?

As should be clear by now, the maximum carbohydrate intake allowable on the low-carb days is simply one that does not prevent ketosis. On a CKD, where the number of low-carb days are limited due to the carb load, it is important that carbs are kept low enough to ensure that the dieter enters ketosis reasonably fast (ideally within 36-48 hours). The amount of carbohydrates that can be tolerated depends on the individual, whether ketosis has been established or not (more carbs can generally be tolerated once in ketosis), and whether the body has fully adapted to using ketones as fuel. A maximum of 30 grams per day is a good rule of thumb, but experimentation is key. We have also seen that the body can produce all the glucose the brain needs from breaking down amino acids, so no carbs are required on the diet per se, but they help make food choices less monotonous and allow the inclusion of natural fiber rich vegetables (more on this below).

The minimum protein intake is in turn determined by what is needed to keep the muscle from having to turn to breaking down muscle protein. Studies referenced in The Ketogenic Diet (pp. 56-60) suggests that as little as 120-150 grams of protein per day regardless of calorie levels is enough to prevent muscle protein breakdown in sedentary individuals. Regardless of diet, weight training individuals require more protein to meet the increased need to repair the structural damage caused by training. Furthermore, on a ketogenic diet additional protein is needed during the first three weeks or so as more protein is converted to glucose before the body fully adapts to using ketones as fuel. A general recommendation is to consume between 0.9-1 gram per pound/1.9-2.2 grams of protein per kilogram of LBM (lean body mass, i.e. bodyweight minus fat weight) for the first three weeks OR 150 grams, whichever is higher. After full adaptation has taken place, protein intake could be lowered somewhat to a minimum of about 0.8 grams per pound/1.75 grams per kilogram of LBM. Using total bodyweight instead of LBM is all right for leaner individuals, but more obese subjects should, if possible, base protein intake on an accurate measurement of LBM as the additional bodyfat might lead to a sizable excess of protein. As even caliper measurements are not 100% reliable, individuals basing protein requirements on LBM calculated by that means should probably overestimate slightly to ensure adequate protein intake (when in doubt, always err towards too much protein rather than too little). Also, since we know that 54% of all ingested protein will appear as glucose in the bloodstream compared to 100% for carbs, we can note that for every gram of carbs ingested protein intake goes down by two grams.

A more trickier question is whether there is a maximum allowable intake of protein and what role fats play on a ketogenic diet. If the body can extract all the energy it needs from stored body fat there would seem to be little use for fat in the diet. If anything, fat intake would seem to counterproductive as the body would first use the dietary fat for energy before tapping into stored fat. The more fats are ingested, the less body fat is burned. Why not keep fats and carbs down and use an all-protein diet?

Actually, there are diets out there that do just this, the most sensible of which appears to be none other than Lyle McDonald’s The Rapid Fat Loss Handbook (Amazon link), a variation of the Protein Sparing Modified Fast (PSMF). This diet cuts everything out except protein and some very low calorie vegetables, essentially reducing caloric intake to the amount of protein needed to prevent muscle mass loss; for most people this will mean a miniscule 600 to 1,000 calories a day! What is burned is almost exclusively body fat and that at quite an impressive rate too. So why not go with that? First of all, the low amount of calories will signal to the body that there is a serious food emergency to which it will respond by shifting into an energy saving mode where energy is spared by slowing down all possible processes of the body; the result of this metabolic slowdown is lowered energy needs causing fat breakdown to slow down significantly (this is why dropping calories too low will result in less fat loss). The diet does include periodic breaks (single meals or longer refeeds) to offset this, but this is still an issue. Added dietary fat simply helps keep the calorie count up which will do much in keeping the metabolism active provided calories are not dropped too low. The very low calorie count will also make it very difficult to sustain any kind of heavy training and will more than likely make your life seem like a living hell, even if that hell is one heck of a fat burning machine. McDonald makes it very clear that this is a CRASH diet that should only be followed for very short periods of time in emergencies where weight needs to be shed very quickly (a lot of water weight will accompany the fat loss). No crash diet is ultimately a healthy diet and difficulties keeping the weight off long-term after such a regime is also an issue. If you want to try this, definitively read McDonald’s book first. Done wrong, this kind of diet can potentially kill you.

Secondly, fat helps promote ketogenesis. We saw above that 54% of all ingested protein will be turned into glucose (compared to 100% for carbs and 10% for fats). If protein levels are excessive, it can lead to an excessive production of glucose (and thus raised insulin levels) that will prevent ketosis. Conversely, much less glucose is produced when more calories come from fats. We can thus say that carbs are anti-ketogenic (prevents ketosis) and fats ketogenic (promotes ketosis) with protein being mildly anti-ketogenic. When ketogenic diets are used in the treatment of epilepsy, the ratio of grams fat to grams protein plus grams carbohydrates (ketogenic ratio) is kept between 2:1 and 5:1 which will stimulate deep ketosis (for yet unknown reasons, ketone concentration needs to be high to prevent seizures which is also why water intake is restricted for epileptics). Epilepsy research tells us that 1.5:1 is about as low as most people can go in order to produce ketones (lower ratios are known to work for some, especially those who have been on a ketogenic diet for an extensive period of time). Worked out as fat percentage of calories, 1.5:1 adds up to 77% fat (2:1 is 81% fat and 5:1 91% fat). Importantly, this research is based on individuals not engaged in exercise which helps keep blood glucose levels down. A case in point is that individuals engaged in heavy weight training often have no problems establishing ketosis following 1:1 levels, i.e. 69% fat, or even less. The lower the ketogenic ratio is dropped, the more exercise will matter and the more individual differences will become visible. Bodyopus recommends a 75% fat ratio which adds up to 1.3:1, also below the 1.5:1 rule of thumb.

Recently, the importance of establishing ketosis has also been questioned. Lyle McDonald has stressed that adequate protein intake should never be sacrificed for ketosis. A similar sentiment is echoed by Chris Shugart and TC Luoma in their article on the T-Dawg Diet version 2.0, where they see the benefits of ingesting a carbohydrate containing postworkout drink outweighing the importance of uninterrupted ketosis. As a matter of fact, the Anabolic Diet is not even designed to be a ketogenic diet, and should rather be labeled a low-carbohydrate or high-fat diet. The 55-60% fat intake the Anabolic Diet recommends works out to a ketogenic ration of 0.6:1 to 0.7:1 (note that this is either misquoted by Lyle McDonald in his BodyOpus notes where he states that the Anabolic Diet recommends 65-70% fat calories OR was changed after the 1995 edition I own); this ratio is already mildly anti-ketogenic and, together with the 30 grams of carbs, is designed to keep the trainee OUT of ketosis. In practice, this might not be enough for everyone though. In a 1999 interview, DiPasquale states very clearly his opinion that ketosis is actually very catabolic and that just dropping carbs very low while keep the aforementioned fat ratio will cause the “metabolic shift” where the body becomes a fat burning machine while avoiding the evils of ketosis.

At this point, the research does seem to point to some advantages of ketosis, but it might not be as important for dieting as originally thought. A tentative suggestion is to worry first about protein and only then about ketosis. In sum, manipulating the ketogenic ratio upwards (more fat, less protein + carbs) is a good place to start when troubleshooting problems with establishing ketosis as long as protein is kept adequate to migitate muscle loss, i.e. not going below 0.8 grams pound/1.75 grams kilogram LBM. For epileptics the priority is the opposite; high ketone concentration is what prevents seizures and, as a consequence, some lean body mass loss due to the low level of protein intake of a high ketogenic ratio is acceptable. In fact, some people do report better results on the Anabolic Diet (my experience is the opposite though) and it might be worth trying both diets to compare results. Whether ketosis is desirable or not may be debated, but at least it seems clear that deep ketosis is not something a dieter should aim for as lower ketone concentrations seems to lead to better fat loss anecdotally. What is also clear is that a ketogenic diet works well; in the end the whole discussion about ketosis vs. no ketosis on a low-carbohydrate diet may turn out to be a moot one. Ketosis is also a reliable indicator that the diet has indeed started to use fat as the primary fuel and is as such a valuable feedback mechanism.

Should I use a ketogenic diet to diet down then?

Not necessarily. Anecdotally, for some a ketogenic diet is a disaster and they do much better on a traditional carbohydrate diet. It is also my belief that what is optimum has to do with much more than whether the diet itself is effective, including social and personal motivations as well as willingness to accept the side-effects of this diet. Side-effects include smelly breath when in ketosis (ketones are excreted in the breath as well), having to avoid the ever-present carbohydrates so tied to social life in our society and having to structure training around the diet (more on this below). The diet can also be hell until the brain adapts fully to using ketones as fuel causing diziness, mental lethargy and a feeling of near constant hunger (the worst usually passes in a few days, but symptoms may last for two to three weeks especially on the CKD due to the carb load slowing down the adaptation some) - Dr. DiPasquale goes as far as recommending against running heavy equipment during the first week. The only way to find out if this diet works well for you is to endure the transition to a ketone metabolism, i.e. the first three weeks. Ketogenic diets are also not the way to go without extensive medical consultation for pregnant or breastfeeding women, children or persons with certain illnesses including diabetes and kidney disorders. People prone to eating disorders should probably also stay away from the cyclical ketogenic diet, as the carb-load that follows several days of low-calorie low-carb eating is very similar to a food binge. The diet does appear to be as safe as any diet, but if you constantly feel alarmed of what it might do to your cholesterol, blood pressure or whatever, you will probably want to look at other alternatives. Potentially, the diet also carries many benefits including better fat loss, less allergies (reported by many) and a more stable mood as you get off the insulin rollercoaster (not to mention the almost total lack of constipation on the low-carb days… the carb load is another story…). Personally, I have much more energy on a ketogenic diet and feel mentally clearer which is one of the main reasons I lived on one for well over a year.

Part II: The cyclical ketogenic diet (CKD) in practice

Preliminaries

Get a good scale especially if the one in your bathroom has a tendency to show different values depending on how you stand on it. Many home scales are not very accurate (as can be seen when comparing several of them against each other), but what is most important is that they are consistent so you can track your relative weight loss (i.e. going from 103kg to 100kg and going from 101.5kg to 98.5kg both equals 3kg no matter if your scale is correct or not).

Have your bodyfat measured using either calipers (cheap) or underwater weighing (expensive). Stay away from all kinds of electronic bodyfat devices as they are notorious for being off the target especially for subjects who carry above average levels of muscle mass. It takes a lot of practice to become proficient at caliper measuring, so select your expert carefully and make sure to ask the same person to take follow-up measurments to ensure consistent measuring. The scale is simply not enough on its own as it doesn’t differentiate between whether the lost weight was muscle or fat. Tracking bodyfat levels, you can accurately state the ratio of lost muscle to fat. This is ultimately the best way to know whether the diet did it’s job well or not. If you lost 20 lbs/9 kg, the majority of which was hard-earned muscle, your diet was clearly a disaster no matter how impressive it looks by scale.

At a minimum, arrange to have your cholesterol (total cholesterol as well as HDL and LDL) measured before embarking on the diet. The ratio of “good cholesterol” (HDL) to “bad cholesterol” (LDL) generally improves on the CKD, but there are exceptions and you really need to know how the diet impacts your cholesterol as this can have a tremendous impact on your overall health. Just make sure not to take a second test before a few months have passed, cholesterol levels are known to sometimes increase in the beginning of a radical diet change according to a doctor I spoke to. Preferably, do a complete health check-up. Better knowledgeable than sorry.

Buy Ketostix from your local pharmacy to measure ketone levels in your urine. Just pee on them, wait for 15 seconds and compare the color against the chart on the bottle; the picture shows a negative result (beige color) and a positive trace ketones result (light pink). The darker the strip, the higher the ketone concentration. Ketostix are not necessary for experienced ketogenic dieters, who can easily tell whether they are in ketosis or not from how they feel and the metallic taste in their mouth, but are essential for beginners. Ketostix help monitor how quickly ketosis is established, and is an invaluable tool in determining how many carbohydrates you can tolerate without being thrown out of ketosis and in troubleshooting reasons for not becoming ketogenic (such as artificial sweeteners which affect some people but not others). Just be aware that Ketostixs are not 100% reliable since they only measure EXCESS ketones spilling into the urine (urinary ketosis) and are sensitive to hydration levels (drinking a lot will naturally dilute the ketone concentration in the urine) - it is very possible to be in ketosis even with no traces on the sticks. The only reliable way to assess the level of ketosis is to measure ketone concentrations in the bloodstream; some blood glucose meters used by diabetics can do this. That kind of accuracy is rarely needed on a ketogenic diet, but for a diabetic rising ketone levels are a potential life and death situation. The depth of ketosis people enter also varies a lot from person to person. In theory, fat loss is best with only traces of ketones so don’t make it a hobby to try to reach very deep colors! Ketostix are an important tool, but don’t invest all your emotion into them.

Make up a plan for how you will measure your calories. Based on research that shows that ketogenic diets usually cause people to eat less than on a carbohydrate based diet (due to the blandness of the fare, the high amount of fat that slows digestion and the general appetite blunting associated with the diet), some proponents (such as the late Dr. Atkins) makes a case for just eating as much as you want, even when targeting fat loss, as that should be less than what you would normally eat anyway. This might be the case generally, but unfortunately this has given rise to the notion that one can eat “unlimited amounts of fat and protein”. Eat too many calories on any diet, and you’ll pack it on (it is a myth that all excess calories on a ketogenic diet are lost in the urine, the ketones that are lost in urine represent very negligible calories). That’s just basic physiology as explained earlier. Foods heavy on fat are very calorie dense; it is easy to overeat stuffing yourself with oils, bacon and whatnot - especially if you are an athlete with a healthy appetite. On the flip side, some people will eat way too little causing metabolism to slow down and the tearing down of muscle protein for glucose. If you are an athlete, you really MUST track your calorie levels which is really the key to fine-tuning the diet through adjusting calorie levels and the ketogenic ratio as needed based on the feedback received from the scale, bodyfat measurements and the ketostix. What you need is a good food scale (no, this doesn’t have to mean an expensive electronic model), food nutrition tables appropriate to the part of the world you live in (many countries have this information online, an example being Fineli maintained by the National Public Health Institute of Finland) and familiarizing yourself with how to count calories and calorie ratios. A good piece of software, such as FitDay, can help a lot as well as speed up things tremendously.

Inform your near friends and family about the diet so you and they don’t end up in awkward situations involving food. If you want to be really hard on them, just give them the link to this article… Remember that not everyone knows what a carbohydrate is and what low-carb food is.

Stock up on the basic vitamins/minerals (at least multi-minerals, magnesium and vitamin C) and foods you will need, such as high-quality oils, meat in the freezer, eggs, cheese, bacon, some kind of fiber containing vegetables (see below), cream and so on and so on. You might get good deals if buying some ingredients, such as eggs, in bulk. You might also consider purchasing one of the Atkins cookbooks or peruse the web for low-carb recepies. These make a world of difference if you find the diet getting very bland. Low-carb bread? Yes, and it’s tasty too.

Plan your weight training and other related activities (cardio if you must…) around the diet and decide on what days in the week you will do the carb-load. The specifics are discussed below.

Setting up the diet

Food intake on the low-carb days

The rationale behind the ratio of carbs, protein and fat has been discussed above. Basically: carbohydrates need to be limited to about 30 grams/day to stimulate ketosis and protein needs to be high enough to prevent the breakdown of muscle protein that is associated with ketosis through starvation. With carbohydrate and protein intake being relatively fixed from day to day, calories are adjusted by manipulating the amount of fat you eat. There are more esoteric ways of working out the macronutrient (protein-carb-fats) ratio, but this formula generally works well with some tweaking as you go. However, it should be noted that if you drop calories low enough to cause the percentage of calories from fat to drop below about 65% you might have trouble entering ketosis and might need to increase fat while lowering carbs and/or protein.

1. Determine calories: start at 12-13 calories per pound/26-28 calories per kilogram of bodyweight and lower moderately as needed to sustain 1-2 lbs of fat loss/week. Calorie levels under 1,200 or 9 calories per pound/20 calories per kilogram should be avoided as the slowed down metabolism will quickly cause fat loss to come to a grinding halt.
2. Determine protein intake based on either lean body mass (especially heavier individuals) or total weight. For the first three weeks, use between 0.9-1 gram per pound/1.9-2.2 grams of protein per kilogram OR 150 grams, whichever is higher. After three weeks, protein intake could be lowered somewhat to a minimum of about 0.8 grams per pound/1.7 grams per kilogram.
3. Determine carbohydrate intake: a good rule of thumb is to keep the daily intake to below 30 grams. That said, the amount of carbohydrates needed to affect ketosis show large fluctuation between individuals and depends on how deep ketosis you are in. You might want to keep carbs very low until you are safely in ketosis and then raise your intake somewhat. Experimentation coupled with ketostix is key here. For now, stick with below 30 grams/day.
4. Determine fat intake by subtracting the sum of calories from protein and carbs from your total caloric intake (recall that every gram of protein and carbs yield 4 calories, whereas fat yields 9 calories per gram). Fat simply makes up for the calories that are left after protein and carbs have been determined.

Here’s an example for a 209 lbs/95 kg individual just starting on the diet for fat loss. For clarity, the example is in pounds only.

1. Calories: 209 lbs bodyweight * 13 calories per pound = 2,717 calories
2. Protein: 209 lbs bodyweight * 1 gram protein per pound = 209 grams. This is 209 grams * 4 calories per gram of protein = 836 calories.
3. Carbs: 30 grams. This is 30 grams * 4 calories per gram of carbs = 120 calories.
4. Fat: Protein and carbs make up 836 protein calories + 120 carb calories = 956 calories. Fat should make up the rest, i.e. 2,717 total calories - 956 calories = 1,761 calories. Since every gram of fat contains 9 calories, this means 1,761 calories / 9 calories = 195 grams of fat.

This results in a diet consisting of 4.4% carbs (120 * 100 / 2717), 30.8% protein (836 * 100 / 2,717), and 64.8% fat (1,761 * 100 / 2,717). The ketogenic ratio is 195 grams of fat to 209 grams of protein + 30 grams of carbs, i.e. 195 / 209+30 = 0.8:1. If this individual has trouble establishing ketosis, carbs and protein could be cut slightly to produce a better ketogenic ratio as long as protein does not go below 0.8 grams per pound, i.e. 0.8 * 209 lbs = 167.2 grams. As noted, protein should not be cut drastically during the first three weeks until protein requirements go down due to adaptation to ketosis.

Food intake during the carb-load

As we have seen, the purpose of the carb load is to refill muscle glycogen, shake the metabolism by raising calories and to cause a surge of anabolic hormones, primarily insulin which is chronically low on a ketogenic diet. The length of the carb load can vary from 24 to 48 hours and is generally done once a week (usually on the weekend for social reasons). For fat loss, 36 hours is usually ideal since it is very hard to gain much fat during this time period, but 48 hours may be used by those who want to maximize their glycogen stores or are using the diet for muscle gain. It should also be noted that the amount of glycogen in the muscle does not affect how much fat you will lose during the subsequent days as the amount of muscle glycogen only determines how much anaerobic muscle work, such as heavy lifting, can be sustained before amino acids need to be broken down for glucose (recall that the depletion of liver glycogen is what puts you in ketosis irrespective of the size of the muscle glycogen deposits). One subjective way of determining the optimum length of the carb load is to take note of when your body starts to look puffy - that’s when you should revert back to the low-carb phase (something bodybuilders will feel more at home with than, say, powerlifters). Also keep a close eye on your weekly fat loss if you use longer carb loads than 36 hours.

There are two ways of going about the carb-load. The first option is to just plainly eat all carbs that crosses your way while keeping protein and fat reasonable (keep fruit intake minimal though, as fructose does not cause optimal supercompensation due to it being the preferential fuel for refilling liver glycogen). Eat, eat, eat, but when the time period is up, it’s back to the calorie counting. Unscientific as it may seem, this option seems to work well for most people. Not having to count calories and being able to eat whatever (skip the alcohol though) is also a good break that helps give renewed energy for yet another low-carb period. The second option is to optimize the amount eaten by following the following guidelines:

1. Carbs: For the first 24 hours, eat 4.5 grams of carbs per pound/10 grams of carbs per kilogram focusing on carbohydrates with a relatively high Glycemic Index (GI). For the second 24 hours, halve the carb intake (i.e. 2.25 grams of carbs per pound/5 grams per kilogram) and focus more on lower GI carbs; if doing a 36 hour carb-load just cut the second 24 hours in half.
2. Protein: 1 gram per pound/2.2 grams per kilogram (the end result will be roughly 15% of calories)
3. Fat: 15% of calories

For our 209 lbs/95 kg example dieter, a 48 hour carb-load would look like this:

1. For the first 24 hours, eat 209 lbs bodyweight * 4.5 grams per pound = 940 grams of carbs (940 grams of carbs * 4 calories per gram of carbs = 3,760 calories), for the second 24 hours eat 940 grams / 2 = 470 grams (470 grams * 4 calories = 1,880 calories).
2. Protein is 209 lbs bodyweight * 1 gram per pound = 209 grams (209 grams * 4 calories per gram of protein = 836 calories) for every 24 hours.
3. Fat is set at 15% of calories (not grams!). For the first 24 hours: 3,760 calories from carbs + 836 calories from protein = 4,596 calories for the first 24 hours. This is 85% of calories, so 115 percent is 1.15 * 4,596 calories = 5,285 calories out of which fat should comprise 15%, i.e. 0.15 * 5,285 calories = 793 calories, i.e. 793 calories / 9 calories per gram of fat = 88 grams fat. For the second 24 hours: 1,880 calories from carbs + 836 calories from protein = 1.15 * 2,716 calories = 3,123 calories out of which fat should comprise 0.15 * 3,123 calories = 468 calories / 9 calories per gram of fat = 52 grams.

So, the dieter should eat 5,285 calories, 940 grams carbs (71%), 209 grams protein (16%) and 88 grams fat (15%) for the first 24 hours, and 3,123 calories, 470 grams carbs (60%), 209 grams protein (27%) and 52 grams fat (15%) for the second 24 hours. If a 36 hour carb load is desired, the values for the second 24 hours would just be halved and eaten over 12 hours. You may note that the percentages do not add up to precisely 100%; this is not an error in the calculations, but merely the effect of doing away with the decimals by rounding.

Mineral, vitamin and fiber recommendations

It goes without saying that the near lack of vegetables and fruits makes mineral and vitamin (micronutrients) supplementation necessary while on a ketogenic diet. The food choices you make on the ketogenic diet can drastically impact the micronutrient profile of the diet; for example, if plenty of diary products (such as cheese and cream) are eaten calcium will be plentiful, but if they are avoided calcium supplementation would indeed be very necessary. If the carb-load is kept decently healthy some of the micronutrient deficiences of the low-carb days can be made up for, but it would be foolish to count on it. The only way to determine what you need with some precision is to do a mineral and vitamin analysis based on your ketogenic diet food profile, but generally using a generic vitamin and mineral supplement with levels at least at the Reference Daily Intake (RDI) is usually sufficient along with some extra vitamin C (athletes should generally use at least 2,000mg daily) and calcium (600-1,200mg/day) if dairy products are not eaten in large amounts. An extra vitamin B supplement can also be in order, especially if the basic mineral and vitaminsupplement does not contain the whole vitamin B complex. Do make sure that your supplements are sugar free!

A total of 20-30 grams of fiber per day is generally considered optimal. The very low level of fiber present on a ketogenic diet can cause noticable effects in the bathroom, although it is quite common to survive well without any extra fiber once the body gets used to the diet. Nevertheless, some fiber supplementation or ingestion of fiber-rich low-carb vegetables is recommended due to the health benefits of fiber (at least 10 grams/day). The table below, one I made when I first embarked on the ketogenic diet, shows how much of each fiber source must be ingested for 10 grams of fiber. All sources are grouped by the amount of carbs this results in making it easy to rate sources at a glance. All weight measures are in grams. My own personal favorite is a big bowl of cabbage with a greasy garlic dressing on top.

Training on the Cyclical Ketogenic Diet

Simplistically stated, the goal of a CKD is to deplete muscle glycogen through exercise on the low-carb days (usually 5 days) to a sufficiently low level before refilling glycogen via a 24-48 hour carb-load. It follows that a cyclical ketogenic diet without a sufficient volume of exercise will quickly lead to fat gain as the huge amounts of carbs eaten on the carb-load will quickly cause the glycogen stores to overflow with the excess converted to fat. It is hard to say exactly how much volume is sufficient based on available research on glycogen depletion during weight training, but in his book Lyle McDonald says that a 36 hour carb-load requires about 5 sets of 10-12 reps @ 70% of 1RM (the maximum amount of weight that can be lifted once) per bodypart and a 48 hour carb-load approximately 8 sets per bodypart at the same intensity. Data on other intensity zones are not available, but, say, the standard Westside Barbell powerlifting template ought to be enough. It is also imperative that as large part of all muscle groups in the body is worked since muscle glycogen is local to every muscle. If someone did only bench presses, the legs would hardly be depleted at all. A routine with at least some accessory work to supplement the three powerlifts (or variations of them as in Westside) would seem the best option when done for powerlifting fat loss. As a general rule of thumb, powerlifters should not resort to bodybuilding-style “pumping” when dieting; keep the weights up to retain strength! In sum, lifters following abbreviated routines, such as Heavy Duty, or training infrequently should look at doing a Targeted Ketogenic Diet instead or look into carb-loading less infrequently (such as once every 10-14 days) to accumulate more volume.

Since training speeds up the burning off of liver glycogen, ketosis is established much faster than without exercise. Therefore, a workout is usually schedule at the end of a carb-load (immediately following or the next day). As this is when muscle glycogen levels are at their highest, this should be the most demanding workout of the week and should involve the largest muscle groups of the body. Bodybuilders usually find that the supercompensated glycogen stores with all the associated water will lead to an unbelievable pump for this workout. An hour of low-intensity aerobics (below 65% of maximum heart rate) is even more effective and can cause ketosis to develop in a matter of hours following an overnight fast, but personally I don’t see why a strength athlete should waste the best opportunity for training with aerobics. Each to his or her own I guess. Without exercise, ketosis is usually developed within three days, with moderate volume weight training within about 1-2 days and with an hour of low-intensity aerobics within a few hours.

As the week goes by and the various muscles are stressed directly or indirectly in previous workouts, the more of a performance hit will you experience in later workouts. Since, again, muscle glycogen is only depleted in a particular muscle when that muscle is taxed at sufficient intensity, a powerlifter should find that a decent second max effort day can be done reasonable well as long as the involved muscle groups have not been extensively taxed earlier. However, if that workout takes place late during the low-carb week, performance will definitively suffer. To maximise the time in ketosis, doing the second workout the day following the first workout is ideal if the routine and body can take it.

A second consideration is that muscle glycogen supercompensation is optimal only if the carb-load is begun within two hours after the muscle has been worked. In other words, only the muscle groups heavily taxed in the workout immediately preceeding the carb-load will be optimally supercompensated. Theoretically, this would point to a full-body workout with reps kept at perhaps 10-12 would be the best way to ensure supercompensation of most muscle groups (for powerlifters, this could be an accessory day). It may not be ideal on paper, but in practice many people find that they achieve good results without worrying about the depletion workout being a full-body one. In my opinion, only consider a full-body depletion workout if it doesn’t destroy your lifting routine, or if it turns out that muscles not worked immediately before the carb-load feel sluggish during the week. Another option is to rotate workouts so that different workouts end the carb-load every week. We will go into specifics below, but carbs also need to be ingested before the workout as being out of ketosis following the workout results in better supercompensation.

In sum, here’s how to set-up training around the diet:

1. Plan in one workout to end the carb-load: this is done either immediately following the end of the carb load or the next day. Make this the most demanding workout of the week. The large amount of insulin released during the carb-load generally make many people feel lethargic so training during the same day as the carb-load ends is not always the best for good training intensity (as a sidenote, never train DURING a carb-load as this will royally mess up glycogen resynthesis!). Keep in mind that you should avoid carbs both during and after this first workout of the low-carb week; a carb-rich postworkout drink would refill liver glycogen in a snap!
2. Plan in one workout to begin the carb-load: this could be a whole body depletion workout or a regular workout. Approximately five hours before this workout ingest about 25-50 grams of carbs (I like candy and a Jolt cola here, but feel free to experiment with slower carbs as well) to begin upregulating liver enzymes. Two hours before the workout a mix of fructose and glucose should be consumed, again 25-50 grams, to refill liver glycogen and exit ketosis. After this workout begin the carb-load immediately, preferably by consuming fast carbs (such as maltodextrin or anything sugarcentric). Keep fat very low for the first hours to kick-start the carb-load.
3. Plan in the rest of the workouts: try not to swear too loudly if this breaks your routine…
4. Plan in aerobic training if you must: If you feel like you must do aerobics, keep intensity low. Above roughly 65% of the maximum heart rate, the aerobic activity will start to effectively cut into muscle glycogen stores which means that performance in the weight room is hampered. Due to the low-level of anabolic hormones during the low-carb days recovery is slower during the low-carb days, so be careful to allow muscles involved in the aerobic activity to recover before training them with weights. Personally, I would not do any aerobics at all during a cyclical ketogenic diet and save all my energy (and muscle glycogen) for the weights. Obviously, athletes whose sport relies on aerobic fitness should not follow this example.

Measuring progress

Recall that when glucose is stored as glycogen, every gram of glucose binds to 2.7 grams of water. Then consider that a cyclical ketogenic diet depletes glycogen stores severely before a carb-load is done that leads to supercompensated glycogen stores (about 1.5 times the normal amount of glycogen for a 36 hour carb-load). As the glycogen is burned off, the water it binds to is also lost. These changes are large enough to show up on the scale in a big way, leading to typical fluctuations on the order of 5-10 lbs/2.3-4.5 kg a week depending on the amount of muscle mass the lifter carries and how severe a depletion is achieved during the low-carb weeks (some people have reported up to a weekly variance of 15 lbs/6.8kg!). Glycogen supercompensation lasts about three days if no exercise is done; with the training done on a cyclical ketogenic diet, there is usually a large drop in weight around the third low-carb day following the carb-load with a huge weight gain following the carb-load. Again, this is nothing but water weight and has nothing whatsoever to do with true fat loss!

So, how do you find out if you’ve lost any bodyfat in the middle of this weight fluctuation frenzy? Since glycogen depletion will be very similar at the end of every low-carb phase, the best bet is to hop on the scale before breakfast on the day when the carb-load begins (also take possible caliper and girth measurements then). The degree of supercompensation reached after the carb-load can vary some from week to week, especially if not following the scientific model, but it is also a good idea to weigh yourself on the morning following the carb-load. This will give you a reasonable consistent reading of your bodyweight at its lowest and highest. Use the pre-load result as the main indicator of lost fat as that should be more stable than the one after the carb-load. As an example, if the scale shows 217 lbs/98.4 kg one week and 215 lbs/97.5 kg the next the morning when the carb-load begins, you can with reasonable accuracy determine that you’ve lost 2 lbs/0.9 kg of fat. As your fat level drops, the weight following the carb-load should also drop although not necessarily at the same rate as the pre-load measurements. If you keep track on both of these weights (pre-load, post-load) in some kind of chart, you will have a good view of how the diet is working for you.

Putting it all together: a sample cyclical ketogenic diet

Joe is a 200 lbs/91 kg powerlifter who wants to become leaner while keeping as much of his hard-earned lean body mass and strength as possible. He would start the diet at 13 calories per pound (2,600 calories) with carbs kept initially below 30 grams a day (120 calories) or less. Protein intake is 1 gram per pound (200 grams = 800 calories) for the first three weeks, after which it can be dropped down to about 0.8 grams per pound (160 grams). Fat makes up the rest of the calories (1680 calories = 187 grams of fat). Depending on fat loss, calories are adjusted down (or even up if needed) via manipulating the fat intake to keep weight loss at 1-2 pounds/0.5-1kg per week. Calories for the low-carb days of the first week would thus look like this:


2,600 calories
30 grams carbs (4.6% of calories)
200 grams protein (30.8% of calories)
187 grams fat (64.7% of calories)

Joe wants to do a 36 hour carb-load. He has the options of just eating a boatload of carbs during the first 24 hours and a slightly more normal amount for the last 12 hours while keeping fat and protein intake decent all throughout OR following the more scientific model. Using the scientific model, Joe would consume 4.5 grams of carbs per pound of bodyweight (900 grams = 3,600 calories) for the first 24 hours and half of the 2.25 grams of carbs per pound used for the second 24 hours of a 48 hour carb-load (225 grams = 900 calories). Protein is kept at the same 1 gram per pound (200 grams = 800 calories) with fat making up 15% of the calories (again, these values are halved for the last 12 hours). Joe’s carb-load thus looks as follows:

First 24 hours	Last 12 hours
5,060 calories 900 grams carbs (71.1%) 200 grams protein (15.8%) 84 grams fat (15%)	1,495 calories 225 grams carbs (60.2%) 100 grams protein (26.8%) 25 grams fat (15%)

Joe wants to carb-load on the weekend, and places his last workout at 11am Saturday morning. The workout lasts roughly 1.5 hours after which the carb-load is immediately begun. The first 5,060 calories should roughly be consumed by noon Sunday with the 1,495 calories consumed before midnight Sunday when the carb-load ends. To ensure consistent results, Joe weighs himself Saturday morning on an empty stomach, which is also when possible skinfold and girth measurements should be taken. If results are not satisfactory, Joe should look closely at the his nutrition diary; did he eat too many carbs (possible hidden in something he didn’t think had any carbs) or excessive protein which could have hampered ketosis (cf. ketostix records)? If yes, he should try to create a more favorable ketogenic ratio (without dropping protein too low!) and perhaps also drop calories moderately. If no, he should drop calories further and perhaps also look into cycling them (i.e. eat less one day, and make up for the loss by adding that to the next day). Or did he do too little training causing the carb-load to fail?

To speed up entry into ketosis, Joe schedules his heavy squat day for Monday and his heavy bench day for Tuesday when he is still fresh. The depletion workout consists of accessory work for both the squat and the bench done at submaximal intensity for reps. Optionally, Joe could do squat accessories on Thursday and bench accessories on Friday (or alternate between doing bench and squat accessories on Friday every other week to maximize recovery). The options and diet constraints are many, which gives Joe a slight headache (this is normal).

The final program looks like this:


Monday: low-carb, heavy squat day. Joe also measures his morning weight on an empty stomach to see how much water weight the carb-load put on his body.
Tuesday: low-carb, heavy bench day (use ketostix to start measuring for urinary ketosis)
Wednesday: low-carb, no training (except perhaps very light restorative or technique work)
Thursday: low-carb, no training
Friday: low-carb, no training
Saturday: Joe gets up at 6am to weigh himself and has 25-50 grams of carbs (5 hours before the workout) before going back to bed. At 9am (two hours before the workout), Joe has 25-50 grams of glucose and fructose (a couple of bananas and a Jolt does the trick) together with some protein and fat. The accessory workout is done between 11am and 12.30pm after which the carb-load is immediately begun.
Sunday: Carb-load until midnight (bed time!)

Before embarking on the program, Joe makes sure to have his cholesterol and skinfolds taken. Since he has a digital camera, he also snaps some “before” pictures to compare the final result against. He also weighs himself and gets the mineral and vitamin supplements he needs along with a low-carb cookbook and ketostix. He even remembers to tell his friends in advance of his diet so they know that they should only throw food surprises his way on the weekend when he can eat pretty much anything (unless Joe is too preoccupied with keeping that too scientific all the way…). And not the least, Joe orders The Ketogenic Diet to make sure he thoroughly understands the diet.

Further reading

We conclude this review with a somewhat cursory link section dealing with many aspects of the diet. Weary from writing a long article, this link section is still somewhat under construction. Other link suggestions are warmly welcome.

Ketogenic diets for seizure control in epileptics

• The Atkins diet, which is very similar to the low-carb days described, has been tried with good success as an alternative to the protein and water-restricted ketogenic diet traditionally used in treating epilepsy. See for example,
  Eating Your Way to Seizure Control (good intro based on a study from 2003)
  A modified Atkins diet is effective for the treatment of intractable pediatric epilepsy, a study from early 2006.

Taking a peep inside our boat shed on the mainland was one of the first, well the first, thing I did at the end of the journey up to the summer cottage. I had ordered a used Buffalo Bar several weeks earlier, but so far only dad, who picked it up for me, had seen it. There it was, but it wasn’t quite what I had bargained for. Or more to the point, it wasn’t the Ironmind Buffalo Bar I thought I had bought.

My heart sunk. Just kidding. After taking a closer look at the beast, I concluded that I had not paid 195 euros/244 dollars in vain. It was a good sturdy bar even if not as rugged as an Ironmind original, the camber was even and save for some very light surface rust (probably from its week in the shed - part of normal maintenance) and chalk stains where the previous owner had used to grip it, the bar was in pristine shape.

Compared to a standard powerlifting bar’s 125 cm/49.2″, here represented by my chrome plated generic bar that will have to go sooner or later, the Buffalo Bar is a whopping 141 cm/55.5″ between the sleeves to allow for a wide grip when squatting. This is wide enough to comfortably allow it to be gripped outside the rack uprights without risking one’s precious fingers. Interestingly enough, my version is still 8 cm/3.2″ shorter than a regular 220 cm/86.6″ bar. What gives? Obviously, the weight sleeves are shorter, 33.5 cm/13.2″ against a 42 cm/16.5″ for my regular bar. This made me alarmed at first, but after doing the math I could conclude that it is still good for between eight (my new rubber coated plates) and ten (my black iron plates) 20 kg/44 lbs plates a side, i.e. a total weight of between 340 kg/748 lbs and 420 kg/924 lbs. Unlike a normal bar, the weight sleeves are also slightly angled upwards which makes the plates stay put a lot better. The camber appears to be closer to 2″ than the 3″ of the Ironmind original, but having used the bar for a few squatting sessions now, I can attest that it is more than enough to remove ALL biceps strain even when suffering from symptoms akin to biceps tendonitis. The bar weighs around 19 kg/42 lbs, enough to call it a regular 20 kg/44 lbs bar.

The pictures below show the bar loaded with the new weight plates in the rack and compared with the regular crappy bar. The lowermost picture shows how big the camber is in practice when the bars are lying next to each other.

For what it’s worth, the Buffalo Bar that now graces the Voimaharjoittelu.net pages has bigger dimensions than this one, but for 200 euros/250 dollars less, I am more than content owning what must be a pretty uniquely dimensioned but well crafted Buffalo Bar. It will come to serve me and my gym visitors more than well.

The first powerlifting book to graze my vast shelves was Power (1998) by legendary Judd Biasiotto. Described as a book written by a “guy weighing 131 pounds [59.5 kg] with legs that look like a pair of pliers in shorts who can squat 575 pounds [261 kg]”, Power was packed with twenty-eight short chapters on everything from psyching up to lifting technique. Suffice it to say, this little gem dynamited with valuable information made me more than a little favorably disposed toward Biasiotto’s and Arndt’s The Bench Press. I had been aware of this book for some time, but my recent foray into the finer points of benching technique made me finally decide to invest some of my hard-earned cash on it ($14.95 USD for the book and $12.00 airmail from DrJudd.net). Subtitled Training & Techniques of the World’s Greatest Bench Pressers, this sounded like just the ticket to learning more intricacies from lifters who benched during the era when heels were firmly planted on the floor (the style I currently use).

The 126 page book consists of chapters around 10 pages long on a selection of immortal benchers from both the States and Europe who saw their heyday between the 1960s and mid 1990s: Anthony Clark, Ken Lain, Ted Arcidi, Craig Tokarski, Chris Confessore, Jim Williams, Mike Hall, Frank Pfaumer, Michael Brügger and Karl Saliger. Loaded with great photos contributed by Powerlifting USA, the chapters tell the story of how these men began their benching career and how they progressed towards the huge lifts they left their mark with. It is intriguing in its own right to read how Arcidi lived in a cellar after being disowned by his father for pursuing a lifting career or how Williams got into lifting by giving a local YMCA barbell a spin in between dancing every Saturday… not to mention how Clark decided to use a reverse grip in order to “break the world record backwards” as proof of God’s strength. The last part of every chapter discusses the lifter’s training on the level of what exercises they believe are most beneficial and what routine they have found to work best for them. Lastly, every chapter also contains a power tip from every lifter that can be anything from “bench with as wide a grip as possible” to “do plate raises for the delts”.

On the whole, the books was a lot more general than I had hoped for. The life stories contribute little towards an understanding of how these lifters honed their technique and training routines over the years. The discussion on training methodology rarely goes beyond “arch your back” and “have long-term goals” and exercises are usually mentioned without much explanation of finer points or why they are important. The Bench Press comes across splendidly as a candid account where the lifter’s tell their own story in their own words, but it would be a mistake to think that this is a good manual on how to learn the dark arts of benching. In my opinion, it should really be subtitled something like Biographies of the World’s Greatest Bench Pressers. As such, it is a great book that should really be owned by anyone interested in powerlifting history or anyone who wants a quick inspirational read with some great photos.

That being said, there is one major exception and that is the section on Ken Lain. He is introduced as a technician who cared for the nitty-gritties of flawless technique. The first thing that struck me [hard] was a discussion on rowing the shoulders back on descent.

One thing Lain does differently is the “shoulder row”, as he calls it. “If you stick your arms straight out in front of you, and shrug your shoulders to your ears, your arms will drop six inches, without even bending at the elbow. So when you are coming down with the bar, you actually row your shoulders towards your ears. This will decrease the distance that you’ll have to drop the bar. Plus you are giving yourself a lot of strength and power off the bottom, by bringing the lats into play.
Biasiotto, Judd and Arndt, Klaus: The Bench Press, Solaris 2001 [2nd ed.]; pp. 39.

Don’t know if anyone besides Lain is known to do this, but this is sure interesting stuff. After talking about the essentials of arching, he goes on to talk about how he grips the bar.

“Most people will grab the bar with their hands, just staying straight on it, and then let the wrists rotate backwards. Take a pencil and let it rest on your thumb and the bottom of the heel of your hand. Look, that is the way my grip is. The tip of my little finger rides right on top of the bar, because I twist my hands slightly forward. By doing this, I’m putting the bar in a direct line to the center of my wrist. […] [This way] you get your delts in a better position to work for you.
Biasiotto, Judd and Arndt, Klaus: The Bench Press, Solaris 2001 [2nd ed.]; pp. 40.

This makes me think Lain’s book Add 50 to 75 lbs. to Your Bench Press might be a worthwhile read, but that is a different story…

As this review is written, it over a decade since the first official Westside training video, Squatting Secrets, was released in 1993. Westside being the innovative and living system it is, it is no small wonder that a lot of things have happened since then, such as relying less on kneeling squats and starting to calculate box squat percentages from the actual competition record instead of from the box max. Still, the foundation remains and this video is an excellent gateway to the Westside system.

Intro

The video begins with Louie Simmons setting the Westside Barbell methods into context by introducing his Elite and World Champion Squatters through pictures on shelves at the club. This gives the viewer a good idea what had been achieved by the club by 1993.

Proper and improper squatting technique

Next, Chuck Vogelpohl enters the stage to show proper and improper squatting form with Louie explaining the do’s and don’t’s in the background. Louie emphasizes that a correct squat is essentially about pushing back against the bar preventing it from forcing the upper body down, i.e. arching the weight up instead of pushing it up with the legs. Proper technique boils down to pushing the stomach hard against the belt and driving the knees apart on descent, then coming up by pushing the chest out and driving the head into the bar. The shins are kept vertically straight throughout the movement. As a result the bar pretty much moves straight up and down without the all too common forward dip. Louie explains that keeping the feet pointed straight forward will allow more power to be generated from the hips, although it makes breaking parallel somewhat more difficult.

Chuck then demonstrates three common mistakes: carrying the bar too low, pushing the knees forward and pushing with the legs first instead of arching the back.

This 5½ minute section alone should be worth much more than the modest price of the tape for people who haven’t gotten their form down. For myself this turned into a big revelation, and I did finally understand concretely how the box squat will teach you proper squat form by sitting back. In essence, the form for the box squat is the same as that for the normal squat.

Box squats

Now turning to box squats, Louie begins by briefly touching on the history of this foundational Westside movement. A very interesting detail is that the box squat was originally known as the “rocky box squat” in the 1960s due to the fact that the lifting shoes with elevated heels then in vogue forced the lifter to rock back and forth to generate enough momentum to actually get off the box. The completely flat soled shoes used today allows the lifter to come straight up, while moving the stress off the quadriceps to the actual squat muscles (hip, lower back etc.).

Louie and Chuck then show a useful technique for teaching beginners how to box squat. Many novice lifters have difficulty continuously sitting back on lower boxes without at some point dropping straight down. To cure this the trainee begins by squatting off a high box. When he has good form an inch is pulled off the box forcing him to sit back further. Once his form is good at this level another inch is taken off, and so on until a very low box height is reached. When squatting with proper technique, form will actually improve the lower the box. This is because lower boxes force the lifter to sit back more and will put more stress on the hips and buttocks. Thus, Westsiders prefer to squat off fairly low boxes.

Continuing to cater for the budding box squatter (although Matt Dimel used this method to break the 800 pound squat barrier), the four box levels are introduced. Chuck first does reps off his 17 inch/43 cm high box, where Louie says one should be able to handle about 10% more than one’s maximal squat. He then proceeds to a parallel box (15 inches/38 cm), then to just slightly below parallel (apparently 13 inches/33 cm) and, finally, to a very low box. A beginner would use this cycle to first build up to a max on the high box, then drop some 50 lbs/23 kg for each lower box (naturally, with low weights smaller jumps should be used; I think Louie is just giving an example of what weights commonly need to be deducted).

Capping off the discussion about box squats, hassock squats, or soft cushion squats, are introduced. An original Simmons invention from the early 1970s, this box makes the lifter sink in without a solid base making it tougher to get off and hitting the muscles differently. The hassock would usually be trained for three or four weeks and then either a new max would be attempted or the box switched to a hard box of the same height for another three or four weeks. Since the hassock squat more closely resembles a competition squat than the box squat, it is especially used a few weeks prior to a meet.

Usually 65-80% of the box max would be used in speed box squatting, with Chuck doing 8 to 12 doubles with loads in the 70% range and 6 to 8 doubles if using weights in the 80% range.

Power good morning/arched back good morning

Now 22 minutes into the video, the focus is switched to the arched back good morning. Simulating the beginning and end of the squat, this movement is done in pretty much the same way: push the knees and buttocks out and arching the back while bending over close to parallel with the floor and then coming back up. The feet width should be the same as for squats. Sometimes the lower position would be held for 4 seconds to train the static contraction needed when squatting heavy. Adding to his previous gems, Louie notes that Mike Bridges’ squat basically was an arched-back good morning which broke parallel. Finally, he talks about the importance of strong hips and obliques (heavy side-bends are the ticket).

Hassock squat workout

Next an actual filmed dynamic hassock squat workout is shown featuring Mark Borda and Chuck Vogelpohl doing 465 lbs/210 kg and 505 lbs/229 kg respectively with a cambered bar. To increase muscle tension short rest periods (45 seconds to 1 minute) are used, which makes it possible for two people to finish a squat workout in less than 20 minutes.

The workout opens with the Guns N’Roses track Welcome to the Jungle echoing through Westside Barbell Club. Matt Dimel and Louie are changing weights and shouting encouragements for the two lifters who take turns in the rack. The training pace is indeed very fast; Louie and Matt hurry to change weights, then immediately the lifter is changed and the bar gets moving for an explosive double. By the time Welcome to the Jungle is finished Mark has done 4 sets and Chuck 3 sets, in less than four minutes!

AC/DC’s Highway to Hell starts to come out of the speakers. If there are any signs of fatigue it is not from the lifters but from the tape viewer watching set after set fly by. If you like to be stressed out, try viewing the workout with fast forward!

After just under 12½ minutes both lifters have done a total of 10 sets, the last set with heavier weights (Mark 505 lbs/229 kg, Chuck 600 lbs/272 kg).

Special exercises

A variety of special exercises used to build up the squat are then presented. First up is the belt squat, which is done to hit the quadriceps pretty much neglected by the box squat. Done on deadlift day, this movement is done with a weight hanging from a special hip belt that puts the weights in front of the body (a dip belt will not suffice!). Standing on a platform to allow the weights to hang straight down, the trainer performs a normal squat. According to Simmons, a normal working weight for a 700 pound/317 kg squatter is 500 lbs/226 kg for five reps! Handle squats, a variation of the belt squat where the weights are held from handles, are then shown.

Next squats in an isokinetic machine are demonstrated by Mark Borda at two different force meter positions. This is followed by Louie demonstrating pull-throughs done for the glutes (bent legs) and the lower back (straighter legs, heavy forward lean). Louie says to use sets of 10 to 15 reps with heavy weights.

Moving on to abdominal training, Louie first shows heavy side-bends (or side deadlifts) which he recommends for strengthening the obliques (weights up to bodyweight are used at Westside). The controversial sit-up is then discussed. As Louie puts it, crunches are safe, but “most exercises that are perfectly safe don’t have much use for strength”. Crunches leave out the hip flexors, which are precisely what need to be developed for lifting heavy iron. If the back hurts while doing sit-ups it is simply because the back is too weak. Straight-legged sit-ups on a flat bench with a lower pulley are shown, both in a dynamic and static form (where the movement is held for 6 seconds at the top for 5 reps).

Louie then turns to a discussion of different forms of leg raises, including hanging, lying and bent and straight-leg leg raises (the last two shown in a leg raise rack). To alleviate a stiff back caused by squatting, Louie recommends doing hanging leg raises with the toes touching the bar on every rep. Since the lower abdominals are harder to develop, leg raises should always be done first in an ab workout.

Taking a sudden unexpected move, Louie proceeds to hit himself over the stomach with an iron pole to help the abdominals contract individually and build up the abs for pushing out during the squat. Not only looks impressive, it sounds impressive too!

In between exercises how to use knee-wraps are discussed and how to wrap them for a lighter man (figure eight crossing) and heavier men (straight around). At Westside, knee wraps are only used in meets, never in training. Louie also very briefly talks about erector shirts.

Partner assisted neck bends while lying on a flat bench are then introduced. A strong thick neck is essential for heavy squatting since, as mentioned, the neck must be driven into the traps on the ascent.

Next Chuck reappears, now in the power rack. He demonstrate high bar squats with a moderate stance (to increase the pull in the deadlift), short-range good mornings (to strengthen the beginning and end of the squat), straight-legged good mornings (for hamstrings, buttocks and lower back) and bent-legged good mornings (which simulate a conventional deadlift and is great for building great erector strength). Chuck then demonstrates the Zercher squat, which is basically a squat with the bar held in the crook of the elbows. Louie explains that this exercise is great for teaching people proper squat form. Kneeling squats (for the hip flexors) are then shown, which Louie claims will in combination with the Zercher squat (for the abs, hamstrings and glutes) easily put 50 pounds on anyone’s squat and deadlift. Then safety bar squats are shown, which Louie says are potentially detrimental for the shoulder and knees but a great tool to build a very strong back.

Now stepping out the rack, Chuck does a few reps of the variety of partial deadlifts similar to Olympic power pulls. This exercise is credited for having helped Matt Dimel squat 1010 lbs/457 kg for a world record. This movement build the glutes and hamstrings while taking out much of the stress on the lower back.

Next exercises on the calf/ham/glute machine are shown. The first one is back raises, which in America are commonly known as “hyperextensions” (the European name is used since the back should never be hyperextended). The second exercise is the calf/ham/glute raises, which involves raising the upper body up from the bench by essentially performing a leg curl. At Westside about 100 lbs/45 kg is used on this exercise attesting to how difficult it is to perform even one rep. Lastly straight-legged sit-ups are performed (aka hyper sit-ups [note: the pictures behind this link of the zercher and sit-ups are taken from the video])

Matt Dimel’s box squat workout

After a short summary of some important points and a warning about psyching up in workouts (should be saved for the meets), the last minutes of the video is dedicated to the dynamic box squat workout of Matt Dimel. At a bodyweight of 390 lbs/176 kg at 6 feet/183 cm, Matt prefers to take two minutes between sets. A 13 inch/33 cm hard box is used for four sets at 630 lbs/285 kg, one set with 670 lbs/303 kg and finally a set with 705 lbs/319 kg. As Louie says, the speed is essentially the same on all reps in spite of the weight raise. AC/DC seems to be the big guy’s workout music of choice. Despite his size, Matt’s form seems flawless.
