On a recent episode of the Oprah show, one of the guests was a 51 year old man with the heart of a 20 year old. He’s been following a calorie restriction plan and they said he might be one of the first people to reach 120 years old by following this plan. There have been stories both in the lay press and scientific press about calorie restriction for years and it has been a frequent talk show topic on other many other TV shows. However, before you cut your calories in half in hopes of adding another decade onto your life, you’d better get the other half of the story they didn’t talk about on Oprah.

I’ve seen a lot of strange things in the health field, and although calorie restriction (CR) is the subject of serious and legitimate scientific study, I consider CR to be one of those strange things. Of course, that’s because I choose a different lifestyle – the muscle-friendly Burn The fat, Feed The Muscle lifestyle – but there’s more than one reason why I’m not a CR advocate:

Hunger while dieting is almost always a challenge. There’s some hunger even with conservative calorie deficits of 15-20% under maintenance. Prolonged hunger is one of the biggest reasons people fall off the weight loss diet wagon because it’s unpleasant and difficult to resist. This is why pharmaceutical and supplement companies spend millions of dollars on researching, developing and marketing appetite suppressants. Yet CR advocates put themselves through 30-50% calorie restriction on a daily basis as a way of life in the hopes of extending life span or health.

Practitioners of CR follow a low-calorie lifestyle, but technically, they are not in a chronic 30% calorie deficit. That would be impossible. What happens is their metabolisms get very slow (that’s part of the idea behind CR; if you slow down your metabolism, you allegedly slow down aging). So a 6 foot tall man who would normally require nearly 3,000 calories to maintain his weight, might eventually reach an energy balance at only 1800 or 1900 calories. This is not just due to a ‘starvation mode’ phenomenon, that’s only part of it. It’s primarily because he loses weight until he is very thin and his smaller body doesn’t need many calories any more.

Does caloric restriction really extend lifespan?

The biological mechanisms of lifespan extension through calorie restriction are not fully understood, but researchers say it may involve alterations in energy metabolism (as mentioned above), reduced oxidative damage, improvements in insulin sensitivity, reduction of glycation, modulation of protein metabolism, downregulation of pro-inflammatory genes and functional changes in both neuroendocrine and autonomic nervous systems.

Mouse studies on CR go back as far as 1935 and monkey studies began in the late 1980’s. So far the results are clear on one thing: caloric restriction does increase lifespan in rodents and other lower species (yeast, worms and flies). Studies suggest the life of the laboratory rat is 25% longer with CR (even longer with aggressive CR). Primate studies are still underway and humans have been experimenting with CR for some time. In primates and humans, biomarkers of aging show signs of slower aging with CR. This makes many proponents talk about this CR as if it were a sure-thing, already proven through double-blind randomized clinical human trials.

The truth is, there is NO direct experimental evidence that you will live longer from practicing CR. Due to the length of human lifespans, we will not have the necessary data for at least another generation and perhaps multiple generations. Even then, it will still be highly speculative whether CR will extend human life at all and if so how much. We can only estimate. I’ve seen guesses in the scientific literature ranging from 3 to 13 years, if CR is practiced for an entire adult lifetime.

Jay Phelan, a biologist at UCLA is skeptical. He says the potential life extension is on the lower end of that range and the increase is so small that it’s not worth the semi-starvation:

“There is no current evidence that lifelong caloric restriction leads to increased lifespan in primates. It’s certainly tantalizing that things like blood pressure or heart rate look as though they are a lot healthier and I believe they are. Whether or not this translates to a significantly increased lifespan, I don’t know. I predict that it doesn’t.”

I don’t quibble qualitatively with their results. Yes, it will increase lifespan, but it will not increase it by 50% or 60%, it won’t increase it by 20% or 10%, it might increase it by 2%. So if you tell me that I have to do something horrible for every day of my life for a 2% benefit – for an extra year of life – I say no thanks.”

Is prolonged caloric restriction unhealthy?

When caloric restriction is practiced with optimal nutrition (CRON), it is not inherently unhealthy. Actually, it appears the reverse is true. First, the weight loss that comes with the low calories produces improvements in the health markers, as you would expect. Second, the meticulous choice of food from CRON practitioners, where they pick high nutrient foods and avoid empty calories means that they are making healthy food choices. Third, advocates say that the CR itself improves health. I wonder, however, how much does CR improve health independent of the weight loss and the optimal nutrition?

By losing fat and maintaining an ideal body composition (the fat to muscle ratio) and eating high nutrient density foods, I propose that even at a more normal caloric intake, you will get very significant health and longevity benefits. I also propose that gaining muscle in a natural way (no steroids) will increase your quality of life today and as you get older.

Aside from the fact that we are not lab rats, the truth is, none of us knows when our day will come. We could get plucked off this physical plane at any moment and have no control over how it happens. My belief is that we should make our lifestyle decisions based on quality of life, not just quantity of life. That includes our quality of life today as well as our anticipated quality of life when we are older. Maybe we ought to be focusing more on “health span” than life span.

Downsides of calorie restriction for life extension

One fact about calorie restriction that they often don’t mention on these talk shows is that the benefits of CR decline if you start CR at a later age. This was discussed in a research paper from the Journal of Nutrition called, “Starving for life: what animal studies can and cannot tell us about the use of caloric restriction to prolong human lifespan.” The author of the paper, John Speakman from the School of Biological Sciences at the University of Aberdeen in Scotland, said that the later in life you begin to practice CR, the less of an increase in lifespan you will achieve. Even if the CR proponents are right, if you started in your late 40’s or mid 50’s for example, the benefit would be minimal. If you started in your 60’s the effect would be almost nonexistent. Essentially, you have to “starve for life” to get the benefits.

While some CR proponents claim that they aren’t hungry and they cite studies suggesting that hunger decreases during starvation, Speakman and other researchers say that hunger remains a big problem during CR – especially in today’s modern society where we are surrounded with convenience food and numerous eating cues – and that alone makes CR impractical:

“Neuroendocrine profiles support the idea that animals under CR are continuously hungry. The feasibility of restricting intake in humans for many decades is questionable.”

Let’s suppose for a moment that CR is totally legit and the claims are true. Many of the proposed benefits of CR come at the expense of what many of us are trying to do here: gain and maintain lean body mass. One spokesman for CR is 6 feet tall and 130 pounds. Another poster boy for CR is 6 foot tall and 115 lbs. Measurements of rodents under CR not only show large reductions in skeletal muscle but also bone mass.

I am not suggesting that these CR practitioners are anorexic, a concern that has been raised about CR when practiced aggressively. However, they are losing large amounts of fat-free tissue and that is plainly obvious for all to see when you look at their bony physiques. I am not imposing my body standards on others, but 115 to 130 lbs at 6 foot tall is underweight for a man by any standard. Furthermore, researchers say that at the body mass indices sustained by most voluntary CR practitioners, we would expect females to become amenorrheic. “One thing that is completely incompatible with a CR lifestyle is reproduction” says Speakman.

With that kind of atrophy, I have to wonder what their quality of life will be like in old age. While many people struggle with body fat for most of their adult lives, I’m sure almost everyone knows an elderly person who wrestles with the opposite problem: they are seriously underweight and they struggle to eat enough and maintain lean body mass.

My grandmother, before she passed away, was under 80 lbs. We could not get her to eat. She was weak and very frail. I have reported many times about the research showing how most overweight people under estimate calorie intake and eat more than they think or admit. In elder care homes, the research has often showed the opposite – the patients over estimate how much they eat. They swear they are eating enough, but they arent and they keep losing dangerous amounts of weight. With underweight, atrophied seniors, weakness means less functionality and lower quality of life and a fall can mean more than broken bones, it can be life-threatening.

Life extension with more muscle

While there is a commonality between CRON and the way I recommend eating (high nutrient density, low calorie density foods), in most regards, CR is the opposite of my approach. In my Burn The Fat, Feed The Muscle program, we go for a higher energy flux nutrition program, which means that because we are weight training and doing cardio and leading a very active lifestyle, we get to eat more. Because we are so active and well-trained, the eating more does not have a negative effect as it would on a sedentary person, who might get sick and fat from the additional calories. We active folks take those calories, burn them for energy, partition them into lean muscle tissue and we enjoy a faster metabolism and extremely high quality of life.

As a bodybuilder, CR is not compatible with my priorities, but hypothetically speaking, if I were to practice a lower calorie lifestyle, I wouldn’t follow an aggressive CR approach. I’d probably do as the Okinawans do. They have a very simple philosophy: hari hachi bu: eat until you are only 80% full. While this does not mean there is a carefully measured 20% calorie deficit, it’s consistent with what we practice in the  Burn The Fat, Feed The Muscle lifestyle for a fat loss phase, and avoiding overeating is certainly a smart way to avoid obesity and health problems. Incidentally, the Okinawans eat about 40% less than Americans, and 11% less than they should, according to standard caloric intake guidelines, and they live 4 years longer than Americans.

If someone is being “sold” on CR by an enthusiastic CR spokesperson, or simply curious after watching the latest TV talk show (where they are looking for controversial stories), it’s important to know that there is more than one side to the story. If you carefully read the entire body of research on CR, you will see that the experts are split right down the middle in their opinions about whether CR will really work. CR for humans remains highly controversial and there are no guarantees that this will extend your life.

Researchers at the National Institutes of Health in Baltimore, MD put it this way:

“Because it is unlikely that an experimental study will ever be designed to address this question in humans, we respond that “we think we will never know for sure.” We suggest that debate of this question is clearly an academic exercise.”

In closing, let me go back to one of the original questions I was asked: “Can the BFFM food plan also be thought as a longevity lifestyle, but with more muscle mass?” Absolutely beautifully said! That’s precisely what Burn The Fat, Feed The Muscle is.

I believe that by making healthy food choices but doing so at a higher level of calorie intake and expenditure, that we can fend off sarcopenia – the age related decline in muscle mass that debilitates many seniors – while enjoying a more muscular physique, greater strength, and a less restrictive lifestyle. Most gerontologists agree – by making simple lifestyle changes that include strength training and good nutrition, you can easily turn back the biological clock 10 years without going hungry.

Nowadays, sport athletes are becoming more health-conscious and perhaps even fairer in their goal to become as physically fit as possible. Rather than relying on all sorts of steroids and drugs to increase their strength and endurance, most sport athletes – as well as their trainers and managers of course – are simply focusing their energies on finding the proper and balanced diet.

Why Eggs are Beneficial for Athletes

EGGS ARE NUTRIENT RICH –  One egg has 13 essential nutrients in varying amounts, including
high-quality protein, choline, folate, iron and zinc, for only 75 calories.

What Makes Egg Protein Different

The protein found in eggs is so rich that it’s often used as a basis for comparison for other foods containing egg protein. Egg protein can be found in both parts of eggs: egg white, which is also called albumen, and egg yolk. Egg yolk however is rich in cholesterol so it’s best to concentrate on eating egg white…even if it tastes bland compared to egg yolk.

The protein found in eggs has been proven to be most helpful to human growth, a factor that athletes definitely need. Studies have shown that as much as 93.7% of egg protein provides actual benefits to the person drinking or eating them. On the other hand, milk can only help people as much as 84.5%. As for beef and fish, expect help in the quantitative value of 74.3% and 76% respectively from them. When you compare them vis a vis, egg protein comes up the absolute winner.

Where or How to Obtain Egg Protein

In the old days, athletes simply tried to benefit from egg protein by drinking them raw or having someone cook several eggs for them then eating them all.

These days however, medicinal companies have created egg protein health products that give you all the benefits with nary of the disadvantages.

Egg Allergy: Why Some Athletes Can’t Take Egg Protein

Unfortunately for some athletes, an allergy to eggs will expectedly prevent them from benefiting from egg protein. Worse, there will be a lot of foods that will be in the forbidden list because of their allergy. Contrary to popular opinion, skipping breakfast is not the way out to egg allergies. There are more to eggs than mere omelets and Eggs Benedict. Eggs can be found in dozens of other dishes, cakes and other pastries just to name a few.

When someone with egg allergy persists in digesting food containing eggs just to benefit from its protein contents, the body’s immune system will automatically raise its defense shield and view anything with egg in it as an enemy. When this happens, the body may start malfunctioning to the point that the individual may feel dizzy, nauseous, and itchy in certain areas of his body. The person may also feel pain in the head or stomach as a result.

How to Know If You Have Egg Allergy or Not

An athlete should undergo an egg allergy test before taking any egg protein to improve his performance. A skin test is the most common technique to determine if one’s allergic to a particular object or food. A liquid sample of egg protein is placed on a certain part of your body – usually your arm – to see if any allergic reaction would incur when your skin comes into contact with egg protein. You may also have to answer questions regarding the frequency in which you develop or display certain reactions when a particular dish – in this case, eggs – is eaten. Your family’s medical history may also play an integral role.

It’s a sad fact that there has been a lot of bad hype going around about eggs for a long time. Obviously, there’s a good side to eggs, and it’s called protein. Eggs play a role in weight management, muscle strength, healthy pregnancy, brain function, eye health and more.

Irvingia gabonensis is the latest weight loss supplement to hit the marketplace, saturate the internet with advertisements, ignite forum discussions and flood my email inbox with questions. In the weight loss marketplace, this may gain the dubious distinction of becoming the next hoodia or acai berry (scam), but I’ll just present the facts, make my case and then let you judge for yourself.

Irvingia gabonensis comes from a West African tree commonly known as the wild mango or bush mango. The trees bear edible fruits, and they’re especially known for their nuts which go by many different names including ogbono, etima, odika or dika nuts. Like other nuts and seeds, Irvingia gabonensis is high in fat (50%), and oil can be extracted from them. Irvingia gabonensis is also comprised of 26.4% carbohydrate, 7.5% protein, 2.3% ash and 14% fiber. Dietary fibers are often recommended to aid with weight loss programs as well as for their health benefits.

The first Irvingia Gabonensis weight loss study: 2005

Due to its customary use in African cuisine and reputation as a health food, a research group based in Cameroon (Western Africa) set up a randomized double blind study in 2005 to see if Irvingia gabonensis could help with weight loss. 40 obese subjects, age 19 to 52, were divided into placebo and experimental groups. The experimental group received 1.05 grams of Irvingia seed extract 3 times a day (total 3.15 grams) for 30 days.

Subjects were examined weekly and tested for body weight, body fat and hip/waist circumferences. Blood pressure was measured and blood samples were also collected after an overnight fast and tested for total cholesterol, triacylglycerol, HDL-cholesterol and glucose. The subjects were interviewed about their physical activity and food intake during the trial and were instructed to follow a low fat diet of 1800 calories per day and keep a food record for seven days.

At the end of the 30 day trial, the Irvingia group had lost an average of 5.26 kilos (11.5 lbs) and the placebo group had lost only 1.32 kilos (2.9 lbs). The group receiving Irvingia also experienced a decrease in systolic blood pressure, total cholesterol, triglycerides and LDL cholesterol. HDL cholesterol increased.

This was the first study that suggested a weight loss benefit from Irvingia gabonensis. Why did the Irvingia group lose more weight? It’s not clear, but in studies of free-living subjects, increased weight loss often means that the experimental group ate less, not necessarily from a direct action on metabolism, hormones or physiology.

In-credible weight loss research

In March of 2008, the same research group (Oben and Ngondi) published the results of their second study about Irvingia and weight loss. This time, Irvingia was combined with Cissus quadrangularis, a succulent vine native to West Africa and Southeast Asia. 72 subjects were divided into three groups, placebo, Cissus extract only (150 mg 2X/day) and Cissus-Irvingia combination (250 mg combined Cissus-Irvingia 2X/day).

All the same tests and measurements were taken as in the 2005 study. After 10 weeks, improvements were seen in total cholesterol, LDL cholesterol and fasting blood glucose. The placebo group lost 2.1 kg (4.6 lbs), the cissus group lost 8.82 kg (19.4 lbs) and the Cissus-Irvingia group lost 11.86 kg (26.1 lbs).

Attributing 26 pounds lost in 10 weeks solely to a fiber supplement is highly unlikely if not impossible, so the researchers (Oben and Ngondi) figured there was something else going on. They proposed that PPAR gamma, leptin, adiponectin or glycerol-3 phosphate dehydrogenase could all be potential mechanisms through which Irvingia gabonensis might affect body weight in overweight humans.

They set up another 10 week randomized double blind placebo-controlled study to investigate these possibilities. 120 subjects were divided into two groups; a placebo group and an Irvingia gabonensis group, which received 150 mg of Irvingia gabonensis extract twice a day.

Again, total and LDL cholesterol levels fell more in the Irvingia group than the placebo group (27% vs 4.8%). In the Irvingia gabonensis group, body fat decreased by 6.3% versus 1.9% in the placebo group. Weight decreased by 12.8 kg (28.1) pounds in the Irvingia gabonensis group vs 0.7 kg (1.5 lbs) in the placebo group. Favorable changes were also seen in Leptin (anti starvation hormone that signals brain & body about fat stores), adiponectin (protein secreted from fat cells; higher levels improve insulin sensitivity), C-reactive protein (marker of inflammation and cardiac risk) and fasting glucose.

To the lay person, this 28-pound weight loss (12.8 kilos) looks incredible. To someone familiar with research methods and weight loss research, these results look IN-credible, meaning NOT credible. To the informed and discriminating, results like these do not send you running to the health food store, they raise red flags, prompt more questions and demand more and better-controlled research.

What “controlled research” means

The subjects were advised not to alter their diet or activity, but that doesn’t mean they didn’t alter it anyways. These were free-living subjects, free to eat whatever they wanted and the only way the researchers knew how much the subjects ate or how active they were was from self-reported food and activity records. That’s another way of saying the study was NOT controlled.

A true tightly-controlled weight loss study means that the subjects stay in a hospital or research center metabolic ward where all their food is prepared and delivered to them, which is the ONLY way to guarantee we actually know how much they ate. It also means that activity and exercise levels are monitored. Alas, none of these controls were used in this study and we have no way of knowing the true caloric intake or caloric expenditure of these subjects.

Explaining the anomaly

If these results are questionable, then how do we explain them? I mean, we’re not saying the researchers are frauds, we’re only suggesting that there were some anomalous findings which were parlayed into the latest supplement craze and a thriving business.

The main problem is that self-reporting of food intake is highly inaccurate and makes long term weight loss research very difficult to do. It’s even possible that some subjects may have experienced a sort of “12 week fitness contest” type of effect, whereupon enrolling in the study, they wanted to impress anyone who saw the results. Therefore, they increased their exercise or activity in spite of instructions otherwise. Perhaps some of the subjects got sick and lost lean body mass. Maybe some were bloated and water retentive and simply dropped a lot of water weight. The explanations are endless.

But the story doesn’t end here. There’s another twist! It turns out that one person has done ALL the research to date and the same person owns the product rights.

Am I being overly skeptical?

Sure, I’m skeptical of weight loss supplements. That’s because I’m intimately familiar with their sordid history and I read the research. In case anyone thinks I’m just trying to pick part this particular research only because I’m a diet pill party pooper and supplement skeptic, then think about the magnitude of the claim for a moment and decide for yourself:

The Dubious claim: “28 pounds of fat loss in 10 weeks with NO CHANGE IN DIET OR EXERCISE.”

Let’s do some math, shall we? 28 pounds of fat loss in 10 weeks = 98,000 calories, or 9,800 calories per week, or 1400 calories per day. So, the researchers and makers of this supplement are claiming that this product will raise metabolic rate by 1400 calories per day.

Is it a more reasonable assumption that an over-the-counter plant extract from an African tree caused astronomical increase in metabolism that probably no prescription drug comes close to, or that the research is flawed?

Consumers in the weight loss marketplace have such short memories. Doesn’t anyone remember that last African wonder pill, hoodia? What happened to that one? And why another? How many of these products are already buried in the supplement graveyard? Haven’t we learned our lessons from the past?

Irvingia Gabonensis: The bottom line

With an objective look at the evidence, we can probably conclude that Irvingia is a good source of fiber. Fiber can provide numerous health benefits and play a role in body fat control, but there are cheaper ways to get fiber than expensive African supplements, (starting with your food!) A 30-day supply of Irvingia (60 softgels at 150 mg each) currently retails for $42 to $72.

Future research might show that Irvingia Gabonensis and or an Irvingia and Cissus combination may provide significant health benefits. Existing research already suggests health benefits including cholesterol improvements, glycemic control, antibacterial actions and antioxidant properties. It’s possible that some of the proposed anti-obesity benefits may also be confirmed. But at this time, the evidence is too thin to recommend Irvingia Gabonensis for weight loss beyond what you could get from any fiber product.

It is considered an “essential amino acid” because a person cannot survive without its presence in his or her diet. Amino acids fulfill various metabolic functions in the body. They work as a building block of proteins, antioxidant, neurotransmitter, hormones’ precursors and other body constituents.

Amino acids are found in red meat, dairy products and other protein-containing foods. Amino acid supplementation can help since certain amino acids including lysine, Arginine, methionine, phenylalanine, Ornithine and Histidine stimulate the release of insulin, hormones and glucocorticoids, which promotes the body’s anabolic process. BCAAs (branched-chain amino acids) supplementations are the source of amino acids isoleucine, Valine and Leucine.

Normally, humans cannot synthesize the number of amino acids needed in one’s body. Therefore, you have to ingest them from supplements to maintain proper health and athletic performance. A typical person should consume 1.5 to 1.75 grams of protein for every kilogram of body weight needed for an ample supply of amino acids.

The typical diet today contains an average of 1.2 grams of protein for every kilogram of body weight. However, people who are physically active, such as bodybuilders, power athletes, weightlifters and endurance athletes need larger amounts of amino acids  or 1.75 to 2.2 grams of protein.

Amino acids for athletic performance have been a hot topic in the world of professional sports because of its three benefits:

1) Amino acids build muscles – The muscle tissues contain two important proteins – myosin and actin. These proteins are made up of isoleucine, Valine and Leucine, also known as the BCAAs.  If you include branched-chain amino acids (BCAAs) in you diet, from either supplements or food, it increases raw materials of your muscle tissues, which in turn, contributes to muscle building.

2) Amino acids increase stamina – When a person performs strenuous physical activities, his or her body automatically decomposes proteins and use up BCAAs to compensate for the lack of energy source.

Several studies show that intense physical activities such as cross-country marathons could damage your muscle tissues. However, this can be prevented by replenishing the needed BCAA in the body before or during participating in intense sports activities.

BCAA supplements can help significantly in giving room for energy sources, which allows your body to hold stamina for longer periods. Moreover, taking the required amount of amino acids could help speed up the recovery of damaged muscles, preventing muscle soreness, fatigue and other symptoms of muscle damage.

3) Amino acids improve recovery from fatigue – Branched-chain amino acids also helps in suppressing lactic acid production. This is particularly important for athletes and physically active people since lactic acid is a fatigue-causing substance.

When a person exercises continuously, his or her lactic acid blood levels increases, which results in the decrease of pH in muscles. This results in a sudden difficulty to contract muscles.

Amino acid supplements can replenish your body’s BCAAs, inhibiting the elevation of lactic acid blood levels, even if you’re performing intense exercises.

4) Amino acid supplementation reduces mental fatigue – Your physical performance relies greatly on concentration and willpower. When the amount of neurotransmitter called serotonin increases in your brain, your will power decreases.

This main cause of this scenario is due to the raw material of serotonin called tryptophan, an essential amino acid. When you perform extensive training continuously, this essential amino acid is transferred to your brain, which leads to the production of serotonin. If you take amino acid supplements, it prevents a great portion of tryptophan to enter your brain, which suppresses serotonin production.

These are the reasons why amino acid supplements can enhance both your mental and physical performance. Experience an increase in mental clarity, reduce the risks of infections due to exercise stress and improve athletic performance even under extreme conditions by incorporating amino acid supplements into your diet.

I’ll preface this article by saying that it will help if you have an open mind and accept that some of these facts are a slap in the face to politically correct nutrition in this day and age where fats are admonished by many doctors, health “experts”, the mass media, etc. To start, eating an adequate supply of healthy dietary fats is vitally important to your overall health. Fats are one of the main components in all of the cell membranes throughout your entire body. If you eat enough healthy natural fats, your cellular processes will proceed normally. On the other hand, if you eat man-made, heavily processed, chemically altered fats (damaged fats) that are found in most processed foods, your cellular function will be impaired as these damaged fats become part of your cell membranes, the body will have to work harder to operate correctly, and degenerative diseases can develop. In addition, healthy dietary fats are essential for optimal hormone production and balance within the body and are therefore essential for the muscle building and fat burning processes. Other important functions that dietary fats play in a healthy body are aiding vitamin and mineral utilization, enzyme regulation, energy, etc.

I cringe every time I hear so called “health experts” recommend restriction of dietary fat, claiming that a low-fat diet is the key to good health, weight loss, and prevention of degenerative diseases. Restriction of any one macronutrient (protein, carbs, or fat) in your diet works against what your body needs and can only lead to problems. All three basic macronutrients serve important functions for a lean, healthy, and disease-free body. As Dr. Mary Enig, Ph.D, and one of the leading fats and lipids researchers in the world, notes in several of her books and articles, there is very little true scientific evidence supporting the assertion that a high fat diet is bad for us. For example, if these so called “health experts” that admonish fat are correct, and a low-fat diet is the solution to good health, then why did traditional Pacific Islanders who typically obtained 2/3 to 3/4 of their total daily calories from fat (mostly from coconut fat), remain virtually free from heart disease, obesity, and other modern degenerative diseases (that is, until Western dietary influences invaded)? Also, why did traditional Eskimo populations, consuming up to 75% of their total caloric intake from fat (mostly from whale blubber, seal fat, organ meats, and cold water fish), display superior health and longevity without heart disease or obesity? Why did members of the Masai tribe in Africa remain free from degenerative diseases and maintain low body fat percentages on diets consisting of large quantities of raw whole milk, blood, and meat? What about the Samburu tribe of Africa, which eats an average of 5 times the quantity of dietary fat (mostly from raw whole milk and meat) as overweight, disease-ridden Americans, yet Samburu members are lean, healthy, and free of degenerative diseases? What about traditional Mediterranean diets, which are known to be very high in fat (sometimes up to 70% fat), and are also well known to be very healthy?

These examples of high fat diets and the associated excellent health of traditional populations around the world go on and on, yet it seems that many doctors, nutritionists, and government agencies still ignore these facts and continue to promote a diet that restricts fat intake. Well, the problem is that the good fats (the natural unprocessed health promoting fats) have gotten mistakenly lumped together in nutritional advice with the deadly processed fats and oils that make up a large percentage of almost all processed food that is sold at your local grocery store, restaurant, deli, fast food joint, etc. These deadly processed fats are literally everywhere and almost impossible to avoid unless you know what to look for and make smart choices in what you feed your body with. Take note that I’m not recommending following a super high fat diet. Active individuals that exercise on a regular basis certainly also need adequate supplies of healthy carbohydrates for energy and muscle glycogen replenishment as well as good sources of protein for muscle repair. The above examples of the high fat diets of traditional populations and their corresponding excellent health were simply to prove the point that you don’t need to be afraid of dietary fats as long as you make healthy natural choices and stay within your daily caloric range to maintain or lose weight (depending on your goals). Following is a list of some of the healthiest fatty foods (some will surprise you!) as well as some of the deadliest fatty foods to try to avoid at all costs:

The Healthy Fatty Food Choices:

• Coconut fat: Coconut fat is approximately 92% saturated fat, yet surprisingly to most people, is considered a very healthy natural fat. The health benefits of coconut fat lie in its composition of approximately 65% medium chain triglycerides (MCTs). Specifically, about 50% of coconut fat is a MCT called lauric acid, which has very potent anti-microbial properties helping to enhance the immune system. Also, MCTs are more easily utilized for immediate energy instead of being stored as body fat. Coconut oil is also an excellent cooking oil for stir-frying, etc. since saturated fats are much more stable and do not oxidize like polyunsaturated oils when exposed to heat and light, which creates damaging free radicals. The best sources of healthy coconut fat are organic coconut milk, virgin coconut oil, or fresh coconut.

• Extra virgin olive oil: Olive oil is approximately 71% monounsaturated, 16% saturated, and 13% polyunsaturated. Choose “extra virgin” olive oil, which comes from the first pressing of the olives and has higher quantities of antioxidants. Unlike most other oils on supermarket shelves, extra virgin olive oil is not extracted with the use of harmful industrial solvents and is one of your healthiest choices for liquid oils. Try making your own salad dressing by mixing a small amount of olive oil with vinegar. This is healthier than most store bought salad dressings, which are usually made with highly processed and refined (chemically damaged) soybean oil extracted with industrial solvents.

• Dark, bittersweet chocolate (>70% cocoa): The cocoa bean is a very concentrated source of antioxidants and responsible for part of the health benefit of dark chocolate. The fat portion of the cocoa bean (cocoa butter) is a healthy natural fat, composed of approximately 59% saturated fat (mostly healthy stearic acid), 38% monounsaturated fat, and 3% polyunsaturated fat. I’ll limit the description of healthy chocolate to ONLY dark bittersweet chocolate with >70% cocoa content. Most milk chocolates are only about 30% cocoa, and even most dark chocolates are only about 55% cocoa, leaving the remainder of those products composed of high amounts of sugar, milk fat, corn sweeteners, etc. Look for a quality dark chocolate that lists its cocoa content between 70%-80%. A dark chocolate with cocoa content in this range will contain mostly cocoa and very little sugar. Keep in mind that although dark chocolate can be a healthy treat, it is still calorie dense, so keeping it to just a square or two is a good idea.

• Avocados or guacamole: The fat in avocados (depending on where they’re grown) is approximately 60% monounsaturated, 25% saturated, and 15% polyunsaturated. Avocados are a very healthy natural food that provides many nutrients, fiber, and healthful fats, while adding a rich flavor to any meal. Try sliced avocado on sandwiches or in salads or use guacamole in wraps, sandwiches, or quesadillas.

• High fat fish such as wild salmon, sardines, mackerel, herring, trout, etc.: Just about any fish or seafood are good sources of natural omega-3 polyunsaturated fats, but the higher fat fish listed above are the best sources of omega-3’s. Due to the radical switch to a higher proportion of omega-6 polyunsaturated fats like soybean oil, corn oil, safflower oil, etc. in our food supply during the middle of the 20th century, the average western diet is currently way too high in omega-6’s compared to omega-3’s, which wreaks havoc in your body. This is where good omega-3 sources like high fat fish, walnuts, and flax seeds can help bring you back to a better ratio of omega-6/omega-3.

• Nuts (any and all – walnuts, almonds, peanuts, cashews, macadamias, etc.): Nuts are great sources of healthy unprocessed fats as well as minerals and other trace nutrients. Macadamias, almonds, and cashews are great sources of monounsaturated fats, while walnuts are a good source of unprocessed polyunsaturated fats (including omega-3’s). Try to avoid nuts that are cooked in oil. Instead, choose raw or dry roasted nuts.

• Seeds (sunflower seeds, pumpkin seeds, sesame seeds, flax seeds): All of these seeds are great sources of natural unprocessed healthy fats. In particular, flax seeds have received a lot of attention lately due to their high omega-3 content. However, keep in mind that omega-3 polyunsaturated fats are highly reactive to heat and light, and prone to oxidation and free radical production, so freshly ground flax seed is the only way to go. Instead of using the store bought ground flax seed, you can buy whole flax seed and use one of those miniature coffee grinders to grind your own flax seed. Try grinding fresh flax seed into your yogurt, cereal, or even your salad. If you’re using a flax oil, make sure it’s a cold-pressed oil in a light-proof refrigerated container, and use it up within a few weeks to prevent it from going rancid. NEVER cook with flax oil!

• The fat in organically raised, free-range animals: This is where most people have been misinformed by the mass media. Animal fat is inherently good for us, that is, if it came from a healthy animal. Human beings have thrived on animal fats for thousands of years. The problem lies in the fact that most mass produced animal products today do not come from healthy animals. They come from animals given loads of antibiotics and fattened up with hormones and fed un-natural feed. The solution is to choose organically raised, free-range meats, eggs, and dairy. At this time, the price is still a little higher, but it is worth it, and as demand grows, the prices will come down.

The Deadly Fatty Foods:

• Hydrogenated oils (trans fats): These are industrially produced chemically altered oils subjected to extremely high pressure and temperature, with added industrial solvents such as hexane for extraction, and have a metal catalyst added to promote the artificial hydrogenation, followed by bleaching and deodorizing agents…..and somehow the FDA still allows this crap to pass as food. These oils aren’t even worthy of your lawnmower, much less your body! They’ve been linked to obesity, heart disease, diabetes, cancer, and more. Even small quantities have been shown in studies to be dangerous. If you care about your health, check the ingredients of everything you buy, and if you see partially hydrogenated oils of any kind, margarine, or shortening, protect yourself and your family by choosing something else. The FDA has mandated that all food manufacturers have to show the quantity of trans fat on all labels by January 2006.

• Refined oils: Even if the oils are not hydrogenated, most oils on your supermarket shelves are refined, even most of the so called “healthy” canola oils. Even most refined oils still undergo the high temperature, high pressure, solvent extraction, bleaching, and deodorizing processes. Anything labeled vegetable oil, soybean oil, corn oil, cottonseed oil, safflower oil, and even many canola oils have been damaged by this refining process. This damages the natural structure of the fats, destroys natural antioxidants, creates free radicals, and produces a generally unhealthy product. Take note that the explosion of heart disease in the middle of the 20th century coincides quite nicely with the rapid increase in the use of hydrogenated and refined oils in the food supply at that time.

• Anything deep fried: including tortilla chips, potato chips, French fries, donuts, fried chicken, chicken nuggets, etc. All of this crap doesn’t even pass as real food in my opinion!

• Homogenized milk fat – Milk fat is a very healthy fat in its natural raw state. Traditional populations around the world thrived in perfect health while consuming huge quantities of raw, non-pasteurized, non-homogenized, full fat dairy products. Once again, food processing ruins a good thing by pasteurizing and homogenizing milk fat, rendering it potentially dangerous inside the human body. Unfortunately, you will find it almost impossible to find raw milk in the US unless you personally know a farmer. Check out realmilk.com for more info on the benefits of raw milk and to find out if it’s available near you. As an alternative, cultured dairy products like yogurt have at least had beneficial microorganisms added back to them making them better for you. Realistically, since you probably won’t find raw milk, sticking to skim milk is the best option. If you use butter for cooking, cultured organic butter is the best option.

It’s axiomatic that the exercises which give you the best results are always the hardest ones to do. If you want a huge back… you row and deadlift. If you want huge legs, you squat… OR… you do THIS   leg exercise – that almost no one wants to do because its one of the hardest of them all.

Which one am I talking about? FRONT SQUATS!

Barbell Front Squat

In my opinion, front squats are one of the absolute best quad builders. Back squats are a tremendous mass builder as well, but front squats introduce an additional level of challenge because they require flexibility, technique, and core strength because the bar must be held and balanced on the front of the shoulders. As such, the front squat does everything the back squat does and more.

One great advantage of the front squat, especially for someone like me, having previously suffered a low back injury (herniated L4), is that the torso can be held in a more upright (vertical position). Since there is less forward trunk inclination, this removes some of the stress and shear forces from the lower back. At the same time, this upright position is closer to a bodybuilding squat and throws much more emphasis on the quads and less on the hips. It is truly a superb bodybuilding exercise.

There are two styles of front squatting, the Olympic lifting style and the crossed arm style. I find that most athletes, and of course Olympic lifters, use the former, while most bodybuilders seem to prefer the latter. The barbell should generally be your weapon of choice, but for bodybuilders, front squats on the smith machine are an outstanding alternative. The Smith machine front squat takes some of the balance issues out of the picture, which allows the physique athlete to really focus on working the muscle rather than worrying about balance and stabilization. Be sure to rotate between both versions, however– barbell and smith machine – because long term overuse or dependency on machines may lead to stabilizer weakness or muscle imbalances and variety is never a bad idea in the physique game. Incidentally, the barbell front squat is an outstanding “core” exercise.

A third version of the front squat worth considering is the dumbbell front squat (especially the sumo or wide stance version). These can be performed holding a single dumbbell with both hands on the front of the shoulders, cupped between both hands (goblet squat) or with two dumbbells, one in each hand, resting on top of each shoulder. The limiting factor on these front squat variations is often the poundage, as holding heavy dumbbells can become unwieldy. This can be partially overcome by performing the dumbbell front squat last in a leg workout or second in a superset, or by manipulating tempo and range of motion so the exercise is made more difficult. The dumbbell variations are also a great choice for women who usually don’t require as much weight as men for stimulation.

I find that the front squat is particularly effective at developing the tear drop shaped vastus medialis portion of the (“lower”) quads, and you can emphasize this effect even more by elevating your heels on a board or a wedge. Elevating your heels is considered controversial and some say that this is damaging to the knees. I’m not convinced that this is the case with a slight elevation and very strict form and controlled tempo, although I would not recommend this method to anyone with existing knee problems. There is certainly a risk to benefit ratio of every technique variation, and you have to decide if the added potential benefit is worth the potential risk, depending on your particular situation (consult the appropriate medical or training professional if you’re not sure)

You can also emphasize the medialis and increase overall effectiveness by working FULL squats (breaking parallel) and only coming up three quarters (no locking out). Have you ever seen Mr. Olympia Ronnie Coleman’s workout videos? I realize that Mr Olympia’s bodybuilding video tapes are not “workout instruction” nor do they really have anything to do with us mere mortals, but I pay attention to everything in the world of bodybuilding, and I did find it very interesting to watch Ronnie front squatting 500+ pounds. I also found it interesting that he went rock bottom and he did ¾ reps without releasing tension for even a single rep. Although he certainly has some advantages over other bodybuilders, everything is relative and he has some ridiculous quads, even compared to other IFBB pros. Indeed, continuous tension ¾ reps are a tremendous technique to employ with the front squat exercise, regardless of whether you’re a novice or a pro. Be prepared to leave your ego at home, however.

In addition to the ¾ reps, try manipulating your tempo. It will limit your poundage even further, but what you sacrifice in strength you will make up in hypertrophy.  Whereas a regular rep might be 2011 or 3011 tempo, or even a full-out explosive concentric with a controlled eccentric, bodybuilders may want to try utilizing a tempo of 3020, or (even harder) 4030. With sets of 10 -12 reps, this will give you a minimum of 50-70 seconds of continuous time under tension. The lactic acid burn around the 10-12 th rep has to be felt to be “appreciated.” The only thing more difficult than continuous tension/non-lockout ¾ reps are continuous tension, non-lockout reps with a slow tempo. Truly a quad killer!

Note: 4-point tempo prescriptions are as follows:

3020 tempo =
3 = negative/eccentric action
0 = pause in stretch/bottom position
2 = positive/concentric action
0 = pause in contracted/top position

So if front squats are so good, why don’t more people do them? Simple – because they’re damn hard. Here is what I usually see happen: Someone will start front squatting (or try to), and they inevitably put on way too much weight. Their form is horrible, it feels totally uncomfortable and unbalanced, so our novice front squatter quits and writes off front squats for good after only one try, and heads back over to the leg press machine.

I usually advise them to unload the bar and master the form first with very light weights, but invariably, ego gets in the way, and 315-405 squatters and 1000+ pound leg pressers don’t want to be seen with a single “wheel” (45 pound plate) on each side of an Olympic bar while they patiently master the technique for a new exercise. Alas, they never learn to front squat, they go back to what is easy and familiar and they never gain all the benefits of this awesome exercise.

“How could you eat that junk? It’s so bad for you!” (nag, nag). “Don’t you know those fries will give you a heart attack?” (nag, nag). “You have to stop eating all that fast food, it’s going to make you fat!” (nag nag). “You have to eat more healthy food like fruits and vegetables – they’re good for you!” (nag, nag). Your friends nag you, your family nags you, your doctor nags you, the health newsletters, websites and magazines – they all nag you, and of course, your personal trainer nags the heck out of you, to stop eating all those BAD FAST FOODS. But does all that nagging you and bad-mouthing the fast food industry really help anyone stop?

It doesn’t look that way. The fast food industry is thriving, even in the bad economy. The Chicago Tribune recently said that McDonalds is “recession proof.”

As one of only two companies to turn a major profit over the last year (the other being Wal Mart), McDonald’s is laughing its way to the bank. In fact, McDonalds plans to open 1,000 new stores this year.

I was driving down Route 95 a few weeks ago and pulled over to use the rest room at Mcdonalds on a Saturday morning (there’s a McDonalds conveniently located immediately off almost every exit up and down the full length of Interstate 95).

The parking lot was full, it was standing-room only inside and the lines snaked around into the seating area! You’d think Brad and Angelina were there signing autographs or something. Nope. Just a regular weekend at breakfast-time.

I was shopping in Wal Mart the same week and I almost passed out when I saw (smelled, actually) a McDonalds… INSIDE THE WAL- MART! Also, with lines.

Yep. It looks like your friends and family’s nagging you to stop eating fast food, and all the messages of the health and fitness industry to get people eating more “health food” are not working!

So what does work?

The results of a new survey from the behavior and psychology section of the journal, OBESITY (Feb 2009) provide some answers:

Researchers at the University of Minnesota School of Public health surveyed 530 adults about their attitudes towards fast foods.

They found that people already know fast food is unhealthy. (like, no kidding!)

The primary reasons they eat it anyway are because of the perceived convenience and a dislike for cooking! (I’d add another: they think fast food is always cheaper than healthy food).

What’s the right approach?

Focus on teaching people how to make healthy eating fast, convenient and easy, because those are the reasons people are choosing fast food in the first place.

So what’s holding us back from implementing or taking this advice?

That said, I’m not going to nag you, scold you or try to scare you out of eating fast food. I’m not going to lecture you about health food (not today, anyway). Nor am I going to bad-mouth the fast food restaurants.

3-MINUTE APPLE CINNAMON OATMEAL

I eat this almost every morning. It’s faster, easier and cheaper than going to the donut place or getting sausage, cheese, bacon breakfast muffins at the fast food joint! (you don’t have to wait in line, either!)

10-MINUTE LAZY PERSON’S CHINESE STIR FRY

This takes 30 minutes, however, if you get a rice cooker and make a giant batch, you can have your rice on standby for instant eats and this will take less than 10 minutes.

It doesn’t get much easier than that. (I like those chinese veggies that come with the little mini-corn-on-the-cobs… reminds me of that Tom Hanks Movie, BIG)

2-MINUTE BLACK BEANS AND SPICY SALSA

This means that my way of eating makes you more muscular and leaner… so you can look hot wearing very little clothes this summer… and be healthier… and save money too.

Train Hard, Eat Right, and Expect Success!

About the Author:

People who are afraid of medications usually prefer to rely on natural or herbal remedies to take care of their various problems. Some athletes feel the same way, too, and this is why they may also choose a natural method over a medical one to help them burn fats more easily.

GREEN TEA – This particular cup of tea is certainly making waves in the healthcare industry. The origins of green go as far back as four thousand years ago.  Green tea possesses a rather unusual flavor that appeals to some while repelling others. Green tea contains several key ingredients that help get rid of undesirable compounds in our body such as calories and – you guessed it – fats!

In a study performed at Birmingham (UK) University, it was shown that average fat oxidation rates were 17% higher after ingestion of green tea Extract than after ingestion of a placebo [2].  Similarly the contribution of fat oxidation to total energy expenditure was also significantly higher by a similar percentage following ingestion of green tea extract. This implies that ingestion of green tea extract can not only increase fat oxidation during moderately intensive exercise but also improve insulin sensitivity and glucose tolerance in healthy young men. [1]

If you’re intending to use green tea as a fat burner, choose a product that has the highest amount of polyphenols, as this is the chief source of benefits of green tea. Secondly, drinking three cups of green tea everyday would sufficiently bring your fat content down.

Coleus forskohlii – This strange-sounding fat burner is a plant that’s found in the Asian region. Studies have shown that properties of this plant can increase the level of fat burning inside our bodies. This particular plant also helps people feel full longer, and therefore eat less. If you’re intending to use this fat-burning technique, make sure that you inform your physician first as it may have unwanted side effects.

YERBA MATE – This is another herbal remedy to help increase the level of fat burning in your body. It is primarily found in the rainforests of Latin America. When you take yerba mate, you can experience the advantages of caffeine without its downside. Simply put, your brain functions better and you feel more energetic without feeling too nervous or restless. Secondly, yerba mate, according to recent studies, can also help your body burn fats more quickly.

EPHEDRA – People who are already somewhat familiar with the trends in the healthcare market would no doubt recognize the name ephedra. Ephedra is actually where ephedrine, a popular stimulant, comes from. Ephedra not only burns fats and calories faster, it can also help you lose weight more quickly because of its appetite-suppressing functions.

Ephedra is both a stimulant and a thermogenic; its biological effects are due to its ephedrine and pseudoephedrine content. [4] These compounds stimulate the brain, increase heart rate, constrict blood vessels (increasing blood pressure), and expand bronchial tubes (making breathing easier). Their thermogenic properties cause an increase in metabolism, evidenced by an increase in body heat.

The Truth about Fat Burning Pills

No matter how powerful a fat burning pill is it won’t work if the person doesn’t adhere to the right exercise and diet at the same time.
Athletes must not expect fat burning pills to work like miracles; they still need to undergo rigorous workouts and a strict diet if they want the fat burning pill to work.

Secondly, you must not allow yourself to be swept away with the bold claims frequently made by fat burning pills. Most of these pills are fond of claiming that their products no longer contain any dangerous ingredients, and that it’s thoroughly safe and effective to use, and so forth. The only way however to determine that is to find someone you personally know and trust to confirm the validity of those claims. Failing that, you can always contact the Food and Drug Administration and know their official stand regarding said product.

Competition is always fierce in all kinds of sports, and this is probably why athletes feel a desperate need to make use of the most effective fat burner available in the market. Their needs however must not make them blind to the risks they’ll be facing if they make the wrong choice. Fat burning is good, natural or not, just as long as it’s done safely.

Working as a fitness professional, there is one type of question I get all the time that shows that many people are missing the big picture regarding the benefits of strength training. This popular question usually goes something like this:

“What exercise can I do to isolate my _______ (insert your muscle of choice – abs, quads, biceps, triceps, etc)?”

It doesn’t matter which muscle someone is asking about, they always seem to be asking how to ‘isolate’ it. My first response to this question is always – “Why in the world would you want to isolate it?”

The first thing I try to teach my clients is that the body does not work well in muscle isolation. Rather, it works better in movements along a kinetic chain; that is, large portions of the body assist other portions of the body in completing a complex movement. In fact, there really is no such thing as true muscle isolation. There is almost always a nearby muscle group that will assist in some way with whatever movement you are doing. However, this article compares attempting to ‘isolate’ body parts via single-joint exercises to the much more effective strategy of performing multi-joint complex movements.

When you attempt to ‘isolate’ muscles by performing single-joint exercises, you are actually creating a body that is non-functional and will be more prone to injury. Essentially, you are creating a body that is a compilation of body parts, instead of a powerful, functional unit that works together.

Now if you really want to end up hobbling around in a body bandaged up with joint problems, tendonitis, and excess body fat, then by all means, continue trying to ‘isolate’ body parts. On the other hand, if you would rather have a lean, muscular, injury-free, functional body that works as a complete powerful unit to perform complex movements (in athletics or even everyday tasks), then you need to shift your focus away from muscle isolation. Believe me, focusing on how well your body functions will give you the side effect of a body that looks even better than it would have if you focused on muscle isolation. For example, take a look at the physiques of any NFL running backs, wide receivers, or even world class sprinters. Trust me when I say that these guys pretty much NEVER train for muscle isolation (their strength coaches wouldn’t be crazy enough to let them), yet they are absolutely ripped to shreds! Just look at guys like Maurice Green or Terrell Owens and tell me who wouldn’t want a physique like those guys.

Another benefit to moving away from the ‘muscle isolation’ mindset to a more ‘complex movement’ mindset is that you will find it much easier to lose body fat. The reason is that by focusing more on multi-joint complex movements as opposed to single-joint muscle isolation, you not only burn a lot more calories during each workout, but you also increase your metabolic rate, and stimulate production of more fat burning and muscle building hormones like growth hormone and testosterone.

Let’s look at an example. The machine leg extension is a single joint exercise that works mainly the quadriceps, can potentially cause knee joint instability in the long run, and doesn’t even burn that many calories. On the other hand, exercises like squats, lunges, step-ups, and deadlifts are all multi-joint complex movements that work hundreds of muscles in the body (including the quadriceps) as a functional unit, create more stable and strong joints in the long run (when done properly), and also burn massive quantities of calories compared to the single-joint exercises.

Cardio exercise is such a strange thing. In theory, it should work so perfectly well for all men and women, but as anyone who has tried it knows, the practicality of it just doesn’t add up.

After all, some men and women do cardio 6 hours, 9 hours, or more per week, and still have belly fat to burn. On the other hand, it works just fine for others.

British researchers wanted to get more insight into this paradox, and studied 35 overweight men and women, who weren’t previously exercising.

(Reference: International Journal of Obesity 32: 177-184, 2008).

Subjects exercised 5 times per week for 12 weeks. That’s a lot of exercise, but it helped the subjects lose an average of 8.2 pounds, which is great – I was positively surprised by the results.

So cardio will work for some people, however, in my experience, it works best in young men, who need the help the least!

Back to the study, the variance in fat loss between individuals was huge. Check this out…

The best subject lost a staggering 32.3 pounds in 12 weeks, while the worst subject actually GAINED 3.74 pounds.

The scientists think they know where things went sour. They classified the subjects into 2 groups, called the “Compensators” and the “Non-compensators”.

The Compensators were hungrier, and as a result consumed an extra 268 calories per day, all but wiping out their cardio efforts.

Therefore, the Compensators lost the least amount of weight, and scientists believe that was due to the huge “compensatory” increase in appetite experienced by this group.

Does your appetite increase when you do slow cardio? If it does, research shows it will ruin your cardio efforts.

So if your cardio program is not working for you, check your appetite and calorie intake to see if you are “compensating” for your efforts. If you are, you might be better off using a program
of high-intensity resistance and interval training (i.e. Turbulence Training) for your weight loss efforts.

As Australian Professor Steve Boucher has shown in research, interval training increases hormones called catecholamines. And increased catecholamines can reduce appetite, among other fat-burning benefits.

In the real world, few people lose 33 pounds after 12 weeks of cardio. Heck, few even achieve an average weight loss of 8 pounds with aerobic exercise.

So again, check your appetite, and consider giving high-intensity exercise a go for your next workout program.

Beat the curse of cardio with high-intensity Turbulence Training.
