CHAPTER 10
NUTRITION FOR MAXIMUM STRENGTH
We all know what a healthy diet is. A healthy diet is based on natural whole foods instead of processed foods, contains a balance of food types, and provides just enough total calories to sustain a healthy body weight. These are the eating habits that every legitimate nutrition expert recommends. However, I don’t believe the standard healthy diet is quite adequate for individuals like us, who push our bodies’ performance limits with physical training. Hard training places unusual stress on the body, and special nutritional measures are required to fully absorb and adapt to such stress, so that the stress builds the body up instead of breaking it down. An abundance of scientific research has shown that athletes perform better when they incorporate advanced nutrition practices that go beyond the standard recommendations.
One of my good friends and most esteemed colleagues is John Berardi, PhD, who is a leading expert on sports nutrition. (If his name sounds familiar, it’s because he wrote the foreword to this book!) A few years ago, John created a comprehensive nutrition program for athletes and fitness enthusiasts called Precision Nutrition. I believe this program represents the perfect hybrid of simple, old-fashioned eating guidelines as described above plus a more cutting-edge, science-based set of guidelines based on the special nutritional needs of athletes.
The essence of the Precision Nutrition Program is a set of 10 eating habits. I recommend that you follow these guidelines while undertaking the Maximum Strength Program.

HABIT 1: EAT EVERY TWO OR THREE HOURS

Eating frequently is proven to elevate the body’s metabolism and limit fat storage. If you eat, say, 3,000 calories in one day and distribute these calories among six separate eating occasions, your body will actually burn more of these calories to produce body heat than it will if you consume 3,000 calories in just two or three meals.
Another benefit of distributing your daily calories among a larger number of meals is that you consume fewer calories at each sitting. When you eat more calories than necessary to satisfy your body’s immediate energy needs, many of the excess calories are stored as body fat. The larger your meals are, the more excess calories there will be, and the more fat you’ll store. When you eat smaller meals more frequently, you are more likely to consume just enough calories at each sitting to meet your body’s immediate energy needs, so fewer calories are stored as body fat. Here’s a sensible eating schedule to follow:
7:00 A.M.—BREAKFAST
 
10:00 A.M.—MID-MORNING MEAL
 
12:00 P.M.—LUNCH
 
3:00 P.M.—MID-AFTERNOON MEAL
 
6:00 P.M.—DINNER
 
9:00 P.M.—PRE-BED MEAL
When you toss in a pre/during/post-training shake, you’re actually looking at seven meals per day. Trust me: It’s easier than it might sound!

HABIT 2: EAT A COMPLETE, LEAN PROTEIN ON EACH EATING OCCASION

Eating protein on each eating occasion is important for three reasons. First, it helps you achieve a high overall level of protein consumption, which is essential to maximize the muscle growth and strength gains resulting from your training sessions. Research has shown that increasing protein intake from normal levels (0.5–0.6 grams per pound of body weight daily) up to 0.7–0.8 grams per pound of body weight daily maximizes the muscle growth resulting from resistance exercise. However, most high-level bodybuilders and strength athletes (myself included) consume at least 1 gram of protein per pound of body weight daily. In this case, as in so many others, I think it’s best to emulate what those with the biggest, strongest muscles do instead of what the laboratory results suggest.
Protein is also the most thermogenic macronutrient; that is, the body has to burn more calories to digest, absorb, and metabolize proteins than it does with either carbohydrates or fats. Consequently, a high-protein diet produces a higher metabolic rate and less fat storage than a moderate- to low-protein diet.
Finally, protein is generally believed to be the most filling of the three macronutrients. Thus, if you maintain a high-protein diet, you are less likely to overeat because of hunger.
The words complete and lean in the formulation of Habit 2 are significant. Not all proteins are complete, and not all proteins are lean. Proteins from plant sources are incomplete (i.e., they lack one or more essential amino acids), while those from animal sources are complete. So you should consume protein from an animal source on each eating occasion. But not all animal proteins are lean, that is, low-fat. Full-fat dairy foods and fatty meats are high in fat. Lean sources of animal protein include lean cuts of beef and pork; low-fat and nonfat dairy products; skinless poultry; fish; and powdered protein drink mixes.
If you are a lacto-ovo vegetarian, rely on nonfat and low-fat dairy foods, egg whites and the occasional whole egg, and milk protein supplements for most of your daily protein. If you’re a vegan, don’t expect to be able to build muscle and strength as quickly as you could if you included animal foods in your diet. Research proves that you can’t.

HABIT 3: EAT VEGETABLES ON EACH EATING OCCASION

Vegetables are a rich source of lasting carbohydrate energy, vitamins and minerals, fiber, and antioxidants. Eating a vegetable-rich diet is proven to provide wide-ranging disease-prevention benefits. The U.S. Department of Agriculture recommends that men eat five servings of vegetables daily for optimal health. The only way you’re likely to hit this target consistently is by getting in the habit of eating some type of vegetable at each sitting throughout the day.
Five servings a day sounds burdensome, but a serving is not large. A serving is defined as one-half cup of cooked vegetables or one cup of raw vegetables or salad. You can do that. In fact, if you ever find that it’s not practical to consume vegetables in a particular meal or snack (how many convenient vegetable snacks can you name?), you can still easily meet your daily quota by doubling up at another meal.
For example, if you have a large two-cup salad as part of your lunch, a smoothie with eight ounces of orange juice and one cup of strawberries, and then four or five steamed asparagus spears with your dinner, you’ve just had six servings of fruits and vegetables in one day.

HABIT 4: EAT VEGGIES AND FRUITS WITH ANY MEAL, OTHER “CARBS” ONLY AFTER EXERCISE

As you probably know, carbohydrate-containing foods are classified by a tool called the glycemic index. High-glycemic carbs are absorbed quickly and provide a quick rush of energy that does not last long and often gives way to a subsequent feeling of lethargy (called rebound hypoglycemia). Low-glycemic carbs are absorbed more slowly and provide sustained energy. Higher-glycemic carbohydrate sources such as bread and pasta do a nice job of replenishing muscle fuel stores after exercise, but at other times their heavy carbohydrate load results in too much fat storage, because carbs that are not needed for immediate energy or glycogen stores are converted to fat and sent to the body’s adipose tissues (which store fat in the body’s midsection).
All vegetables and most fruits have a low glycemic index, so that the carbs they contain are less likely to be converted to stored fat. Some fruits are high-glycemic, but they contain fewer total carbohydrates than high-glycemic grain-based foods and sweets, so they still result in minimal fat storage, if any. Thus, fruits and vegetables are better sources of “anytime energy.”
Note that, generally, your overall level of carbohydrate intake should vary with your training workload, since carbohydrate is your primary energy source for training. If the Maximum Strength Program represents a significant increase in your training workload and/or you find it difficult to maintain lean body mass during the early weeks of the program, you may need to increase your intake of healthy carbohydrates (vegetables, fruits, and whole grains)—so you can be a little less strict in following this particular habit. But most guys will get the best results by following Habit 4 to the letter.

HABIT 5: EAT HEALTHY FATS DAILY

There are three basic categories of fats: saturated, monounsaturated, and polyunsaturated. For optimal health you need to consume a balance of these three fat types. Most Americans consume too many saturated fats, too few monounsaturated fats, and the wrong kind of polyunsaturated fats. High levels of saturated fat consumption are closely associated with weight gain, obesity, and heart disease.
The ratio of unsaturated to saturated fats in the typical American diet is roughly 1:2. The ideal ratio is just the reverse, 2:1 (that is, twice as many unsaturated fats as saturated fats). The largest amounts of saturated fats are found, as you already know, in fatty cuts of meat, whole-milk dairy products, fried foods, and baked goods made with certain oils. You can easily and drastically reduce your saturated-fat consumption by limiting your consumption of these foods. Switch from fatty meats to lean meats, strictly limit the potato chips and french fries, and switch from whole-milk dairy foods to low-fat and nonfat dairy foods.
I’m sure you also know already that even worse than saturated fat, which is healthy in modest amounts, is trans fat, an artificial fat that is unhealthy in any amount. Trans fats are created when food chemists add hydrogen atoms to unsaturated fats to make them more saturated and, in turn, increase their melting point and make them better for baking and prolong their shelf life. Fortunately, the U.S. Food and Drug Administration now requires that trans fat content be listed on food package labels, so it’s easier to eat around this most unhealthy type of fat. High levels of trans fat consumption have been shown to increase heart disease risk even more than high levels of saturated-fat consumption. Meanwhile, both polyunsaturated and monounsaturated fats lower total cholesterol and LDL (the bad cholesterol). If you see trans fat on a product label, simply don’t buy it.
Good sources of polyunsaturated fats are fish, walnuts, and safflower oil. The most important polyunsaturated fats of all are the omega-3 fatty acids. The omega-3 fatty acids DHA and EPA are essential fatty acids (EFA); that is, they cannot be synthesized in the body, so they must be obtained in adequate amounts in the diet. This is easier said than done, as omega-3 fatty acids are destroyed when the oils that contain them are processed or heated, and most of the omega-3 sources in the modern diet are processed and/or heated. Many experts believe that omega-3 deficiency is one of the most widespread nutrient deficiencies in our society—and that’s a sentiment I share from years of reviewing new clients’ diets.
Omega-3s create healthier cell membranes. In addition, they are important precursors to anti-inflammatory components of the immune system. Omega-3 supplementation has been shown to improve cardiovascular health, sympathetic nervous system function, immune function, skin health, and a host of other health parameters. The best sources of omega-3 fatty acids are identical to the best sources of polyunsaturated fats in general: fatty types of fish (salmon, halibut, etc.), flax seeds, and walnuts. Unfortunately, there aren’t many other foods that contain high levels of omega-3s. For this reason, I recommend that everyone take a daily fish oil supplement (see page 191).
There’s another class of essential fats, called the omega-6 class, that you have probably also heard about. Omega-6 fatty acids are found abundantly in grains, eggs, and poultry. The typical American diet is not deficient in omega-6 fats, so you don’t need to make any special effort to add them to your diet as you do with omega-3s.
Last but not least are the monounsaturated fats. Good sources of these healthier fats include olive oil, almonds, cashews, and natural peanut butter.

HABIT 6: DON’T DRINK BEVERAGES WITH MORE THAN ZERO CALORIES

One of the easiest ways to trim a surprising number of calories from your daily intake is to make a few key beverage substitutions. America has become a beverage-crazy society in the past quarter century, and this trend has had a significant impact on our bodies. The sheer variety of beverages available in stores has exploded, and serving sizes have also increased substantially. Currently, one in five calories in the average American’s diet comes from beverages.
By replacing high-calorie beverages with zero-calorie beverages (preferably plain water), you can improve your body composition significantly without making any other changes in your diet. This strategy was demonstrated by a study done at Children’s Hospital in Boston. Researchers there invited 103 teenagers to pick noncaloric drinks they liked and then delivered a supply of those drinks to their home refrigerators. Apparently, the kids actually drank the stuff, because consumption of sugar-sweetened beverages tumbled by 82 percent over six months. The subjects also lost one pound of body weight per month, on average, in the study period.
If you’re serious about getting leaner and healthier, the only liquids you should regularly consume are water, green tea (a rich source of antioxidants with virtually no calories), and protein shakes.

HABIT 7: EAT WHOLE FOODS INSTEAD OF SUPPLEMENTS WHENEVER POSSIBLE

Your body was designed to absorb and metabolize natural, unprocessed foods, including fresh fruits and vegetables, seafood, and lean meats. Optimal health and performance are possible only if your diet is based on these foods. Nutritional supplements should have only a small place in your diet.
Some nutrition experts believe that nutritional supplements should be avoided altogether. My view is that this extreme position is not quite realistic, especially for men who push their bodies hard in the gym. If you’re gunning for maximal strength, you need to consume fairly large amounts of protein frequently. Frankly, you can eat only so much meat. So there’s nothing wrong with snacking on protein shakes and bars and chugging down high-protein posttraining drinks on the way home from the gym.
Believe it or not, research has actually shown that a pretraining shake containing protein (and carbs, ideally) improves long-term muscle mass gains more than a post-training shake alone. Unless you want to eat half a chicken breast immediately before you train and the other half immediately after you train, a good protein powder is your best bet. I recommend Biotest Surge as a pre/during/post-training protein source; you can find this and other protein powders online or at health food stores.
There are a handful of other nutritional supplements that are acceptable and even beneficial. Creatine supplements are proven to increase strength beyond the level that creatine-containing foods can. Fish oil supplements, as mentioned above, make it much easier to get the amount of omega-3 fatty acids that is needed for optimal health. I’ll say more about each of these types of nutritional supplements later in the chapter.

HABIT 8: PLAN AHEAD AND PREPARE MEALS AND SNACKS IN ADVANCE

It’s one thing to know what you ought to eat and when. It’s another to actually eat what you should eat when you should eat it. Eating by the rules on a consistent basis requires a consistent effort to plan and prepare ahead of time so that you don’t get stuck with the fast-food drive-through as your only option to cure a raging hunger. You should put the same degree of planning and preparation into your eating as you put into your training. You always know where and when you will do tomorrow’s training session, and what sort of training you will do. Similarly, you should also know where and when you will eat tomorrow’s meals, and more or less of what these meals will consist. And if any of these meals requires shopping and preparation, it’s important that you take care of these things ahead of time.
There are a few simple measures you can take to ensure you always have the right foods available at the right times. One is to identify restaurants that serve healthy meals near where you’ll be. If you are planning tomorrow’s meals, and you know that you will be away from home for at least one of them and you are unable to take something with you, simply choose a restaurant from your list that you know you will be able to access for this meal, and order wisely.
Another measure you can take is to make sure your kitchen is always well stocked with lean protein sources, fresh vegetables, and other healthy foods. Pick one day of the week to do your food shopping for the following week, and err on the side of buying more than enough to get you through the next seven days, so you never run out of wholesome options and wind up calling the pizza delivery guy to bail you out. One strategy I’ve employed with great success is to cook in bulk on the weekends and freeze whatever I don’t plan to use immediately. When things are hectic during the week, I can just defrost and chow down instead of having to cook an entire meal from scratch.
Stashing healthy snacks in your car and at work makes it easy to take care of your mid-morning and mid-afternoon needs. Options for the car and office include fruits, mixed nuts, low-carb beef jerky, protein powder, and protein bars (in a pinch).
Finally, I recommend that you build a repertoire of dinners and other menus that you can prepare at home. If you like to cook, this is easily done; you just have to find recipes that include lean protein, vegetables, variety, and no high-glycemic carbs (except after exercise). If you don’t like to cook, you need to find recipes that meet these requirements and are very quick and easy to throw together. A great source of such recipes is the Gourmet Nutrition booklet that comes with Dr. Berardi’s Precision Nutrition kit. Visit www.precisionnutrition.com to order it. Another good source is Power Eating by Susan Kleiner, PhD.

HABIT 9: EAT AS WIDE A VARIETY OF FOODS AS POSSIBLE

Different foods offer different nutrition profiles. No food provides every nutrient your body needs, and many natural foods provide nutrients that few or no other foods provide. This is especially true of plant foods, which contain dozens of useful phytonutrients (nonessential but highly beneficial plant nutrients, many of which function as antioxidants) that help the body in many ways. So the best way to ensure that your body gets enough of each nutrient is to consistently eat a wide variety of foods.
I’m not talking about merely hitting all of the basic food groups each day. I’m talking about getting as much variety as possible within each food group. Your animal protein should not always come from beef. Romaine lettuce should not be your only green vegetable. You get the idea.
The greatest potential source of variety in your diet comes from vegetables. Each type of vegetable has a nutrition profile that’s a little different from that of any other. By mixing up the vegetables in your diet, you will supply your body with the greatest balance of healthful plant nutrients. The five categories are dark green, orange, legumes, starchy vegetables, and other vegetables. The table on page 186 lists examples of each.
Make an effort to consistently include vegetables from all five categories in your diet.

HABIT 10: DON’T “BREAK THE RULES” MORE THAN 10 PERCENT OF THE TIME

On the Precision Nutrition plan you will eat 6 times a day on average, or 42 times a week. In order to enjoy the full benefits of this system, you must break the rules no more than 10 percent of the time, or roughly 4 times a week. That’s not much, so you should try to obey the rules every time you eat. When you do break a rule, consider it water under the bridge; don’t have a guilt fit. Just move on and eat right next time, and the next time, and the next time.

THE CALORIE QUESTION

Most eating plans start by telling you how much you should eat and then tell you what (and possibly when) to eat. Precision Nutrition is different. In this system you may eat as much as you feel like eating. Why? Because if you follow the 10 Precision Nutrition habits, train consistently, and focus on performance as I’ve emphasized, you simply won’t be able to eat more calories than your body needs to fuel and build your muscles.
Counting calories is totally unnecessary; I never have my clients do so. All you have to do is eat enough to feel comfortably satisfied at each meal. Over time, you learn to eat the right amount instinctively. The quality of your nutrition, the frequency of your feedings, and your hard work in the gym will combine to ensure that there will be no “extra” calories left over for fat storage after your muscles’ needs have been met. Trust me.

A SAMPLE DAY OF PRECISION NUTRITION

Exactly how you put the Precision Nutrition principles into practice depends on when you train. The reason is that non-fruit-and-vegetable carbs are to be consumed only during the first two hours after training (and at breakfast, in those who tend to tolerate carbs well). Here are sample one-day eating plans for those who train in the morning (before work) and for those who train in the late afternoon or evening (after work).
MORNING TRAINING MEAL PLAN
TRAINING PRE/DURING/POST. Biotest Surge shake (or comparable shake; never train on an empty stomach!).*
BREAKFAST. 1/4 cup oats (dry measure) with two scoops low carb chocolate whey protein powder (stirred in), one apple (or other fruit).
MID-MORNING MEAL. Protein bar with one orange (or other fruit).
LUNCH. Grilled chicken spinach salad with fresh veg gies, olive oil and vinegar for dressing, fish oil soft gels (half of daily dosage).
MID-AFTERNOON MEAL. One scoop low-carb protein powder mixed in water and ¼ cup almond/walnut mixture.
DINNER. Lean red meat with steamed vegetables.
PRE-BED MEAL. Smoothie with one scoop low-carb vanilla pro tein powder, ½ cup blueberries (or other berries), ice, and ½ cup cottage cheese; one ta blespoon natural peanut butter (eaten sepa rately); fish oil soft gels (half of daily dosage).
*NOTE: Those looking to get leaner should use half the recommended dose of protein pow der and add one scoop of low-carb protein powder instead.
EVENING TRAINING MEAL PLAN
BREAKFAST. Omelet with eggs (two or three) plus one or two additional egg whites with veggies (chopped onions, tomatoes, spinach, and diced tomatoes), fish oil soft gels (half of daily dosage).
MID-MORNING MEAL. One scoop low-carb protein powder mixed in water and ¼ cup almonds or other nuts; fish oil soft gels.
LUNCH. Spinach salad with additional veggies and grilled chicken and olive oil and vinegar for dressing, fish oil soft gels (half of daily dosage).
MID-AFTERNOON MEAL. 1 cup low-fat cottage cheese with ¼ cup rasp berries, ¼ cup walnuts (or other fruit or nuts).
TRAINING PRE/DURING/POST. Biotest Surge shake.*
DINNER. Grilled chicken; sweet potato; green beans.
EVENING SNACK. Smoothie with one scoop low-carb vanilla pro tein powder, ½ cup blueberries, ice, and ½ cup cottage cheese; one pear (or other fruit).

SUPPLEMENTS WORTH CONSIDERING

So much money is spent on the marketing and advertising of nutritional supplements that it’s difficult to avoid being brainwashed. The underlying message of these communications is that you cannot maximize your health and athletic performance without nutritional supplements. The reality is that only a very small number of supplements are scientifically proven to enhance the benefits of resistance exercise, and their effect is modest.
In other words, in the pursuit of maximal strength, supplements are optional. The four primary nutritional supplements that I consider worth a try for virtually everyone are creatine, fish oil, protein blends, and vegetable supplements.

Creatine

Creatine phosphate occurs naturally in the body and is one of the most important sources of energy for high-intensity (anaerobic) muscle contractions. Creatine phosphate is able to provide energy so rapidly that it is the muscles’ primary energy source for maximum-intensity efforts such as heavy weightlifting and sprinting. The muscles store it in extremely small amounts, though, so it lasts no longer than 15 seconds during maximum-intensity muscle work.
A tiny percentage of our creatine phosphate stores is synthesized in the body. The rest comes ready-made in protein-rich foods, including fish and beef. But even these foods contain only small amounts of creatine phosphate. That’s why scientists in the 1990s began to look at creatine supplementation as a potential means to enhance high-intensity muscle performance (strength, speed, and power) by increasing the availability of this particular energy source in the muscles. They quickly found that various creatine phosphate precursors, including creatine monohydrate, are readily converted to creatine phosphate in the body and, when taken supplementally, increase creatine phosphate stores in the muscles far beyond the levels that can be achieved by diet alone.
As few as five days of creatine monohydrate supplementation increase creatine phosphate levels in the body by 10 to 40 percent. Dozens of research studies have shown that these increases translate directly into faster muscle development and strength building. However, some people find that creatine has little effect. Scientists refer to these individuals as “nonresponders.” And even among the majority of individuals who do respond to creatine supplementation, some benefit more than others, so if you’re interested in trying it, you’ll just have to see what it does for you.
I recommend that you take three to five grams per day. You can mix the powder into any drink, but most lifters prefer to just include it with their pre/during/posttraining shake. On off days, simply stir it into your green tea. Do not fall for the hype that says that you need a special creatine delivery system full of carbs and a thousand other ingredients. Plain old powdered creatine is very affordable and is all you need to get the job done. You do not need to worry about beginning the supplementation process with a “loading phase,” either; simply taking a small dosage over the course of three to four weeks will get you the same results without any of the minor gastrointestinal problems (stomach bloating and gas) that come with loading.
There has been some public concern about side effects associated with creatine supplementation, including muscle cramping and altered liver and kidney function. However, formal scientific studies have found no evidence of any side effects, except muscle weight gain, and recent comprehensive reviews of the literature have concluded that even long-term creatine supplementation is safe. If you have questions, ask your doctor.

Fish Oil

The American Heart Association recommends that we eat fish at least twice a week to nourish our bodies with healthy fat. But eating fish twice a week or even daily doesn’t provide enough of the essential fatty acids EPA and DHA to meet the body’s needs. A good rule of thumb is to aim for a combined 3,000 milligrams of EPA and DHA per day. The majority of products out on the market provide 180 milligrams EPA and 120 milligrams DHA per soft gel. Thus, you need 10 soft gels per day to reach your “quota.” While it sounds like a ton, it amounts to only a few teaspoons of oil. Fortunately, some companies have created more concentrated versions to make our lives easier. Biotest’s Flameout, for instance, provides the necessary daily total in only four soft gels. Carlson also makes a quality liquid fish oil that you can use to get your allotted dose quite easily. It’s fairly easy these days to find fish oil, whether it’s at the corner drugstore or at your local health food store.
Regardless of the form you choose, I recommend that you take a fish oil supplement every day. Fish oil can help prevent arthritis, heart disease, psychological disorders, gastrointestinal problems, eye issues, and dozens of other maladies that relate to systemic inflammation. Think of it as giving your body the right raw materials with which to build cell membranes.

Protein Blends

As I mentioned above, most successful strength and power athletes (and bodybuilders) consume at least 1 gram of protein per pound of body weight. It is difficult to achieve this level of protein consumption in a calorically efficient way with whole-food protein sources alone. For example, to get 25 grams of protein from lean ground beef, you have to consume roughly 210 total calories. Meanwhile, you need to eat 250 calories of nonfat yogurt to get 25 grams of protein. To get the same amount of protein from a whey protein powder, though, you have to consume only 120 calories. (Although you don’t need to count calories on the Precision Nutrition plan, half the reason you don’t have to count calories is that it’s based on calorically efficient foods.) Protein supplements also afford us more convenience when we’re on the go, and around exercise times, when the last thing we want to do is eat solid food. For these two reasons, I believe that including a powdered-protein drink mix in your daily nutrition regimen is a good idea.
The most popular type of protein supplement is whey. Whey protein is one of two main proteins in milk (the other is casein). It is one of the highest-quality proteins in nature, as it contains all 20 amino acids and high levels of the specific amino acids that are known to be most important for muscle performance and growth (leucine, isoleucine, valine, and glutamine, in particular). Whey protein is also absorbed and metabolized very quickly compared to other proteins. For this reason, it’s a great choice around training times, when you want protein to go to work quickly.
Personally, I prefer protein supplements that combine fast-acting whey protein with slower-acting proteins such as casein. While no protein matches the capacity of whey to increase muscle protein synthesis around a training session, casein actually does a better job of reducing muscle protein breakdown (which is normally elevated after training). Thus, a supplement that combines whey and casein has a more positive effect on net muscle protein balance. If you’re using these supplements during the day as a meal replacement product, opt for low-carb versions and combine them with solid foods (e.g., nuts, fruit).
Other research has shown that protein supplementation is most effective when the supplement is consumed either immediately before or immediately after training. The objective is to make amino acids readily available when the muscles begin their recovery and adaptive response to training in the hours following a training session.

Vegetable Supplements

If you are able to consistently eat five or more servings of vegetables daily, good for you. But only a quarter of American adults manage to consume even three servings of vegetables daily. Vegetable-based nutrition supplements can help fill the gap. You can purchase capsules and powders made of extracts from a large variety of vegetables, fruits, and herbs.
I’m not saying that vegetable supplements represent an equivalent alternative to whole vegetables, but they do deliver a lot of nutrition and are better than skimping on veggies altogether. You can find them at many health food stores.

SUPPLEMENTS TO AVOID

The vast majority of nutritional supplements that are sold under muscle-building (and fat-burning) claims are scientifically proven to have no effect on muscle growth or strength gains. In other words, if you buy them, you’re a sucker. My list of the top supplements to avoid wasting your money on includes arginine, chromium picolinate, DHEA, HMB, and ribose.

Arginine

Several years ago, supplements that are purported to elevate nitric oxide (NO) production in the body became popular among men seeking muscle growth and strength gains. Blood vessels produce nitric oxide, which helps them dilate to increase blood flow. With increased blood flow comes increased oxygen and nutrient delivery to the muscles and fuller, more “pumped”-looking muscles. The amino acid arginine is one of the main substrates for NO synthesis and is the main ingredient in most of the many NO-boosting supplements on the market. However, natural arginine levels far exceed anything you can take in pill form (without GI distress) to stimulate NO production.
The majority of these supplements are marketed with claims that they increase muscle size and strength. However, there is absolutely no scientific basis for these claims. In fact, arginine supplementation has been shown to mute the growth hormone response to resistance training, so it can actually limit mass and strength gains than to augment them.

Chromium Picolinate

An essential trace mineral (i.e., a mineral humans need in very small amounts), chromium is naturally present in foods such as beef, eggs, and spinach. It is also an ingredient in many diet products because chromium is known to assist naturally in the metabolism of carbs and fats, as well as in blood sugar regulation. Many bodybuilders take chromium supplements—usually in the form of chromium picolinate—in the belief that it helps them burn fat and improve their body composition.
For the life of me I can’t figure out why anyone takes supplemental chromium picolinate. Study after study has found that it is completely ineffective. For example, one study from the University of Maryland compared the effects of daily chromium picolinate supplementation with a placebo during 12 weeks of resistance training. The study’s authors concluded, “Chromium supplementation, in conjunction with a progressive, resistive exercise training program, does not promote a significant increase in strength and lean body mass, or a significant decrease in percent body fat.”

Dehydroepiandrosterone

Dehydroepiandrosterone (DHEA) is a relatively weak steroid hormone similar to estrogen and testosterone. Synthetic DHEA is sold as a supplement under claims that it slows the aging process, including the muscle and strength declines that are part of aging, and protects against a variety of diseases and ailments, including heart disease and Alzheimer’s disease.
The original rationale for DHEA supplementation was the fact that DHEA levels naturally peak at age 25 and decline thereafter, roughly in parallel with testosterone levels in men. It was thought that supplementation might slow and to some degree reverse this hormonal decline and any aging processes that might be connected to it. Early studies with rodents looked promising, but the trouble is that rodents produce very little DHEA, so the results did not translate. Recent human studies, including a large two-year study at the Mayo Clinic, have found that DHEA supplementation fails to increase testosterone levels or muscle size and strength gains resulting from resistance exercise.

Beta-hydroxy beta-methylbutyrate

Beta-hydroxy beta-methylbutyrate (HMB) is a metabolite of the essential amino acid leucine. HMB became popular as a muscle- and strength-building supplement in the 1990s because of speculation that it might limit muscle protein degradation following resistance exercise and enhance positive nitrogen balance. The effects of HMB on muscle and strength gains resulting from resistance training have since been investigated in numerous studies. Some have shown that it is effective, while others have shown that it is not.
The majority of studies showing benefits have been poorly designed. A majority of the well-designed studies have shown no benefit. Also, most studies showing beneficial effects of HMB supplementation have involved beginning weightlifters, while most studies involving trained weightlifters have shown no benefit. While there may be a small benefit to HMB at very high dosages, looking at the total pool of research on HMB I can say with confidence that HMB supplementation is not worth the $50 to $60 per month it would cost you!

Ribose

Ribose is a sugar that the body produces through glucose metabolism and is in turn used to replenish adenosine triphosphate (ATP) stores in muscle cells. Therefore, it plays an important role in muscle energy production. Many bodybuilders and strength athletes use ribose supplements in the belief that these accelerate muscle recovery by increasing the rate of ATP synthesis after training.
However, studies have demonstrated unequivocally that ribose does not have this effect. For example, in a double-blind, randomized, placebo-controlled Belgian study, subjects performed an intensive regimen of lower-body strength exercises over a six-day period. Subjects who took a ribose supplement neither replenished ATP stores faster than placebo subjects nor outperformed them in strength tests.
There are literally hundreds of other supplements out there on which people willingly spend money, but from which they get little to no benefit. Covering them all would be beyond the scope of this book, but I hope by presenting these few examples I will save you some cash that could otherwise be spent on high-quality whole foods.
