A Balanced Diet Isn’t Enough

November 14, 2008

by John M Berardi, PhD, CSCS

What The Heck Is A Balanced Diet?
You hear it all the time – from your mom, from dietitians, from doctors, from coaches, heck, even from your uncle Jimmy.

Just eat a “balanced diet” and you should be fine.

Of course, the fact that no one ever mentions what actually constitutes a “balanced diet” only adds to the mystique and allure of this mythical creature.

To your mom, a balanced diet pretty much means whatever she puts on your plate. To your dietitian and doctor, it pretty much means to eat less saturated fat and cholesterol. To your coach, it means whatever keeps you from getting fatter. And to your uncle Jimmy, it means skipping breakfast, having fries and a burger for lunch, and having a 6-pack of Coors Light after work.

For most people, a balanced diet is simply a buzz word for “eating whatever I want to eat.” The phrase is beautifully vague enough to be able to justify their own personal choices with amazing vehemence and rationalization. It’s vague enough to convince folks that no changes are necessary in their daily intake. It’s vague enough for dietitians to suggest that no supplements are required to meet our daily needs.

Yet it’s also vague enough to be utterly useless and void of all utility or meaning. And it’s vague enough to ensure that the rates of diabetes and heart disease consistently increase.

Truth be told, as you’ve probably guessed by now, I hate the phrase “balanced diet.” Indeed, if there were one phrase that should be banned from our collective nutritional lexicon, this is the one. It’s a useless term that is often used to justify counterproductive habits.

How About A Dietary Analysis
To help illustrate my point, just the other day I was searching the medical databases for a host of diet analysis studies.

My goal was to find studies done on athletes, recreational exercisers, and sedentary folks.

And my intention was to find out whether or not their so-called “balanced diets” were actually providing them with the minimum level of nutritional intake established by the very conservative American Dietetics Association.

You see, the ADA establishes nutrition standards for the population at large.

For example, assuming a 2000kcal diet, the average person should be getting the following macronutrients each day, according to the ADA:

Total Fat 65 g
Saturated fatty acids 20 g
Cholesterol 300 mg
Sodium 2400 mg
Potassium 4700 mg
Total carbohydrate 300 g
Fiber 25 g
Protein 50 g

And in terms of micronutrients, here’s what we should be getting to achieve 100% of our recommended daily intake, according to the ADA.

Vitamin A 5000 IU
Vitamin C 60 mg
Calcium 1000 mg
Iron 18 mg
Vitamin D 400 IU
Vitamin E 30 IU
Vitamin K 80 μg
Thiamin 1.5 mg
Riboflavin 1.7 mg
Niacin 20 mg
Vitamin B6 2 mg
Folate 400 μg
Vitamin B12 6 μg
Biotin 300 μg
Pantothenic acid 10 mg
Phosphorus 1000 mg
Iodine 150 μg
Magnesium 400 mg
Zinc 15 mg
Selenium 70 μg
Copper 2 mg
Manganese 2 mg
Chromium 120 μg
Molybdenum 75 μg
Chloride 3400 mg

Again, these numbers are conservative. They’ve been established by the ADA as rock-bottom minimums required to prevent us from contracting nasty diseases.

They say nothing about optimization, mind you. However, they are still useful. After all, if we dip below these levels, we’re in nutritional deficiency land. Cue up pirate songs, eye patches, and the talk of scurvy.

So, in beginning the research review mentioned above, my goal was to uncover some of the published literature, to see if anyone ever actually achieves a “balanced diet” in the real world.

My criterion, of course, would be something measurable. I’d be using a real dietary analysis to determine just what “balanced” actually meant.

My Experience
Now, my experience told me that I’d be pretty disappointed in this notion of a so-called “balanced” diet.

When at the University of Western Ontario working on my PhD, I assisted Dr Peter Lemon with an advanced Exercise Nutrition course. And, as part of the class, every year we had 150-200 students do a personal dietary analysis.

So, for 3 years straight, it was my job to collect these analyses and plug them into a database for further review. And, over the course of 3 years, and over 500 exercise and nutrition students, it was my experience that very, very few of them achieved 100% of the recommended intake of all the macro- and micro-nutrients.

In general, only about 10-15% of them met all of their dietary needs. The other 85-90% were deficient in one or more key nutrients – whether it was zinc, magnesium, omega 3 fatty acids, or protein.

Interestingly, in my hunt above, I found an interesting study published in 2006. This study, published in the Journal of the International Society of Sports Nutrition, corroborated my experience perfectly.

Here’s what the researchers found.

Seventy diets were computer analyzed from the menu of athletes or sedentary subjects seeking to improve the quality of micronutrient intake from food choices. All of these dietary analyses fell short of the recommended 100% RDA micronutrient level from food alone.

In other words, over 70 diets were analyzed from individuals actively trying to improve their nutritional intake. And not a single one even achieved the minimum micronutrient suggested by the ADA!

The Study
If you’re interested in checking out the study details, which I think you should be, here’s the paper for your review.

J Int Soc Sports Nutr. 2006; 3(1): 51–55.
Food Alone May Not Provide Sufficient Micronutrients for Preventing Deficiency
Bill Misner

Introduction
Reference Daily Intakes (RDI) is a new term that replaces the familiar U.S. Recommended Daily Allowances (U.S. RDA). RDIs are based on a population-weighted average of the latest RDAs for vitamins and minerals for healthy Americans over 4 years old.

RDIs are not recommended optimal daily intake figures for any particular age group or sex. Government-established Reference Daily Intake guidelines (RDI) are designed to prevent nutrient-deficiency diseases.

Most nutritionally oriented professionals imply that a balanced variety of foods selected from the Food Guide Pyramid (FGP) will supply all micronutrients at the RDA or new RDI levels necessary to maintain optimal health and prevent nutrient-deficiency diseases. The American Dietetic Association (ADA) has proposed a conservative strategy for managing dietary micronutrient deficiency and sufficiency:

“It is the position of the American Dietetic Association (ADA) that the best nutritional strategy for promoting optimal health and reducing the risk of chronic disease is to wisely choose a wide variety of foods. Additional nutrients from fortified foods and/or supplements can help some people meet their nutritional needs as specified by science-based nutrition standards such as the Dietary Reference Intakes. This position paper addresses increasing the nutrient density of foods or diets through fortification or supplementation when diets fail to deliver consistently adequate amounts of vitamins and minerals.”

Between 1996 and 2005, 70 diets were computer analyzed from the menu of athletes or sedentary subjects seeking to improve the quality of micronutrient intake from food choices.

Surprisingly, all of these dietary analyses fell short of the recommended 100% RDA micronutrient level from food alone.

Therefore, based on diets analyzed for adequacy or inadequacy of macronutrients and micronutrients, a challenging question is proposed: “Does food selection alone provide 100% of the former RDA or newer RDI micronutrient recommended daily requirement?”

Methods
From 70 computer-generated dietary analyses, 20 subjects’ diets were selected based on the highest number of foods analyzed from 10 men (ages 25–50 y) and 10 women (ages 24–50 y).

A First Data Bank Nutritionist IV computer-program default was utilized, defaulted to apply the Harris-Benedict equation, a formula that determines energy expense against RDA micronutrient requirement, by age, gender, and body mass index (BMI).

The purpose of this study was to determine if food intake alone provided the Recommended Daily Allowances (RDA) requirements for 10 vitamins and 7 minerals. The ten vitamins analyzed were Vitamin A, Vitamin D, Vitamin E, Vitamin K, Vitamin B-1, Vitamin B-2, Vitamin B-3, Vitamin B-6, Vitamin B-12, and Folate. The seven minerals analyzed were Iodine, Potassium, Calcium, Magnesium, Phosphorus, Zinc, and Selenium.

The 20 Individual Diets analyzed originated from the following subjects:

1. Two professional cyclists athletes (A)
2. Three amateur cyclists athletes (A)
3. Three amateur triathletes athletes (A)
4. Five eco-challenge amateur athletes (A)
5. One amateur runner athlete (A)
6. Six sedentary non-athletes (S)

Hence, fourteen (14) athletes’ (A) and six (6) sedentary subjects’ (S) diets were analyzed for calorie and RDA-micronutrient adequacy or inadequacy.

Results
Based on each subject’s activity level (caloric expense), age, gender, and body mass index (BMI), 10 of the diets were found calorie-excessive, above energy requirements (4 men and 6 women), but the remaining 10 diets were found calorie-deficient, not meeting 100% of their energy requirements (6 men and 4 women).

When total calorie intake percents were averaged by gender, men consumed only 92.6% of the calories required for their total energy requirements, while women consumed only 97.3% of the calories required to meet their energy requirements.

Of the 20 diets analyzed, 50% were calorie-sufficient and 50% calorie-deficient resulting in an overall -7.4% deficiency for men and a -2.7% deficiency in women (Table 1.).

CLICK HERE FOR TABLE 1

Calorie deficient diets tended to record a greater number of micronutrient deficiencies as compared to the calorie-sufficient diets.

Of the 340 micronutrient entries generated from 17 micronutrients analyzed, all 20 subjects presented between 3 and 15 deficiencies each based on the Recommended Daily Allowances (RDA) value from food intake alone.

Males averaged deficiencies in 40% of the vitamins and 54.2% of the minerals required.

Females averaged deficiencies in 29% of the vitamins and 44.2% of the minerals Recommended Daily Allowances (RDA) required.

The male food intake was RDA-deficient in 78 out of 170 micronutrient entries, or 45.8% of the 10 vitamins and 7 minerals analyzed.

The female dietary intake was RDA-deficient in 60 out of 170 micronutrients or 35.2% of the 10 vitamins and 7 minerals analyzed. Both male and females as a single entity recorded 138 micronutrient deficiencies out of the possible 340 micronutrients analyzed, or 40.5% micronutrient RDA-deficiency from food intake alone. (Table 2.)

CLICK HERE FOR TABLE 2

Accuracy of the individual food-weighed measures, accuracy in reporting foods consumed, and the accuracy of the computer-generated software are factors that affect the accuracy of the results reported in this observational study.

The effect of activity on calorie deficiency in this contingent demonstrates an increased micronutrient deficiency in athletes (A) and surprisingly, the sedentary subjects (S) in this study also posted food-borne micronutrient deficiencies.

Each chronic deficiency proportionately increases the risk of nutrient-deficiency diseases. In highly active athletes (A), micronutrient deficiencies occur at higher rates because calorie deficits are associated with exercise expense.

Food alone in all 20 subjects did not meet the minimal Recommended Daily Allowances (RDA) micronutrient requirements for preventing nutrient-deficiency diseases. The more active the person, the greater the need to employ a variety of balanced micronutrient-enriched foods including micronutrient supplementation as a preventative protocol for preventing these observed deficiencies. (Tables 3, 4, 5).

CLICK HERE FOR TABLE 3

CLICK HERE FOR TABLE 4

CLICK HERE FOR TABLE 5

Concern for micronutrient adequacy from food alone is not a new question. Excerpts 70 years ago (1936) from the 2nd Session of the 74th USA Congressional Record (excerpts) stated:

“Laboratory tests prove that the fruits, the vegetables, the grains, the eggs and even the milk and the meats of today are not what they were a few generations ago (which doubtless explains how our forefathers thrived on a selection of foods that would starve us today).

It is bad news to learn from our leading authorities that 99% of the American people are deficient in these minerals, and that a marked deficiency in any one of the more important minerals actually results in disease. Any upset of the balance, any considerable lack of one or another element, however microscopic the body requirement may be, and we sicken, suffer, and shorten our lives.”

This twenty-subject dietary analysis study is not representative of the entire population, however the results supported by the 1936 congressional record, beg the question:
“Does food selection alone provide 100% of the former RDA or newer RDI micronutrient recommended daily requirement?”

It may be that chronic micronutrient insufficiency from food alone is more fact than fantasy. This study calls for a dietary analysis of a larger contingent of the population to determine if there is an association between chronic suboptimal RDI-micronutrient deficiency and suboptimal health disorders that may digress into disease.

Our Conclusions
In the end, the take home message here is quite clear.

Most people trying their best to achieve a “balanced diet” are falling short, creating personal deficiencies in vitamins, minerals, and more.

In the study above, the nutrients folks were most at risk for deficiency in were:

Iodine – 100% of the diets were deficient in iodine
Vitamin D – 95% of the diets were deficient in vitamin D
Zinc – 80% of the diets were deficient in zinc
Vitamin E – 65% of the diets were deficient in vitamin E
Calories – 50% of the diets were deficient in calories
Calcium – 50% of the diets were deficient in calcium

Of course, this doesn’t mean that nutritional supplements are necessary as a first line of defense. Indeed, recent data have clearly demonstrated that the vitamins, minerals, and phytochemicals found in real food, dose per dose, often outperform those found in pills and capsules.

What it does mean, however, is that if you’re not getting the advice of a nutrition professional, or if you’re not following a sound eating protocol that’s designed specifically to overcome nutrient deficiencies, you’d better get cracking.

The longer you wait, the more at risk you’ll become for a host of nutritional deficiency related diseases and disorders, diseases and disorders you could have prevented simply by changing just a few eating habits.

Protein Problems: When You Need To Say Bye-Bye To Your Current Brand of Protein

November 10, 2008
by Dr John Berardi, CSCS

This week I’m out in Calgary working with Canada’s top bobsleigh and skeleton athletes. And right now, the athletes are in the midst of a testing camp, meaning that they’re all here competing for a position on this year’s upcoming World Cup and Europa Cup squads.

As nutritional support for their hard training is a must, I spend a lot of time with these athletes making sure everything is in place for success – food amount, food type, food timing, and appropriate supplement intake.

Interestingly, as most of the athletes use some type of protein supplement to help meet their high protein needs, every time I’m out here I’m reminded of how many folks are hypersensitive to protein powders – especially whey protein.

In fact, during this trip alone, I’ve had to take 5 athletes off whey protein because of their negative reactions to the stuff – even the so-called “high quality” whey isolates.

One athlete, for example, had extreme bloating and gas from their whey protein supplement. Within 30 minutes of drinking their shake, a big, smelly cloud would fill the room and their belly would bloat up to about 125% of its normal size.

Another athlete, who has used whey protein during training sessions for the last year, thought – FOR THE ENTIRE TIME – that he had a low-grade, chronic head cold due to the extreme stuffy-ness he’d experienced during every workout.

Another athlete, after every serving of whey protein, would build up a thick coating of mucous in their throat as a result of their protein supplement.

And the list goes on…

These symptoms, of course, are commonly associated with food allergies and/or food intolerances. And unfortunately, they are symptoms many of them, and likely many of you, have either failed to recognize, ignored, or just simply learned to live with.

But, as I told my athletes, these symptoms are not normal and should not be brushed aside. Rather, they should be dealt with and eliminated.

So, at this point, let me pose these 4 questions:

How often do you feel gassy and bloated?

How often do you suffer from flatulence?

How often do you have a stuffy nose?

How often do you feel excess mucous production in your head and throat?

If these symptoms above are part of your normal day, it’s time to look to your food intake to see what might be causing the problem or problems.

Specific to protein problems, the symptoms above are typically the result of one or both of the following:

Lactose Intolerance
In certain individuals (those without enough lactase enzyme activity), undigested lactose passes through the stomach into the intestines where it must be fermented. Through this process, lots of gas is formed, causing stomach cramps, bloating, flatulence, and diarrhea.

Protein Allergy/Intolerance
In addition to the above, symptoms can be a result of milk protein allergy/intolerance. While casein protein has been implicated in more cases of milk protein problems than whey, both milk proteins can cause similar issues. This is due to the fact that in some individuals, casein and whey can cause an excessive inflammatory immune response. This leads to mucous production. And high mucous means blocked airways, stuffy noses, and thick throats.

Now, I know. Your supplement manufacturer swears that the protein they’re selling you is a “high quality” isolate. And yes, true high-quality isolates contain very little lactose. But again, it may or may not be the lactose that’s the problem. It could be the protein isolate itself that’s causing the issue.

But, consider this as well…any protein powder that contains “whey protein concentrates” still contains lactose – even if the manufacturer claims it’s a high quality isolate. Therefore if it’s got concentrates, it’s got lactose.

In addition, many protein industry insiders believe that some companies are lying about the quality of their product to increase profit margins. They claim that since it’s much cheaper to use lower quality whey protein concentrate than it is to use a high quality whey protein isolate, some companies are adding concentrate without listing it on the label.

Sneaky, sneaky.

Of course, I’m not trying to kick off a conspiracy theory – rather, I’m just trying to help you look and feel better by avoiding potential dietary problems. And, like I said above, even if you’ve got high quality protein product that is lactose free, you could actually have a protein allergy/intolerance. Therefore the protein type itself would have to go.

Now, without making things too complicated here, let’s get practical with a few suggestions for those of you who think you’re having problems with your protein supplements.

1) Switch Protein Brands
If you consistently get gassy and bloated or stuffy and mucousy after having a supplemental milk protein product, it may be time to switch brands. Your brand might have too much lactose or too high a concentration of certain protein products and either of these could be detrimental.

Indeed, this week one of my athletes switched protein powders from a whey protein isolate to a milk protein blend and within 1 day all of their complaints disappeared. Heck, I’ve even seen athletes switch from one brand of whey isolate to another and have an improvement in function and a removal of symptoms.

2) Switch Protein Types
If you switch protein brands and that doesn’t help, you may legitimately have an intolerance to the milk protein itself.

In such case, you might try switching to rice protein isolates. Rice protein isolates are hypoallergenic and are nowadays fortified to contain a complete compliment of amino acids.

3) Think About Your Dairy
One other thing to also consider if you’re suffering the symptoms above is your dairy intake. Maybe, instead of your protein being the problem, you’re having a problem with milk, cheese, yogurt, etc. Again, the lactose or protein fractions in dairy products may be the culprit, so don’t rule either out.

If it turns out that dairy is the problem, you could switch to non-cow’s milk dairy (goat or sheep’s milk dairy), or you could switch to soy-based dairy like milk, yogurt, etc.

In the end, the point of this article isn’t to make you a dairy or protein hypochondriac. Don’t invent symptoms that don’t exist. However, I do encourage you to think about your protein and dairy intake and consider whether your protein supplements and dairy are helping or hurting you.

If you’re aware of the link between what you eat and how you feel, it’s much easier to begin to change things up if a particular food is problematic.

When Exercise Doesn’t Work

November 3, 2008

by John M Berardi, PhD, CSCS

This week I’ve got no fancy introduction. I’ve got no “journalistic hook.” You see, I recently had an “ah ha” moment that I’ve simply got to share with you. And here it is…

Exercise doesn’t work.

Now that might sound shocking coming from a guy with big biceps and 8% body fat; from a guy that recommends lots of exercise, at least 5 hours per week.

So if this all seems incongruent, I guess I should qualify the statement above. I guess I should have probably said:

Exercise, ALONE, doesn’t work.

My Wake-Up Call
My coming to this realization wasn’t an easy process.

I’ve been working with clients for over 15 years now and although I always knew that diet was an important part of the training equation, I also always harbored some subconscious notion that if I worked my clients hard enough, their lack of dietary effort would be overcome by my super-effective training programs.

Sure, I wanted them to eat well. But if they didn’t (more like, wouldn’t), somewhere deep inside it seemed ok. I figured in the battle of training vs. diet, training would win.

Now, I never said this aloud. However, somewhere I’m sure I felt it. So it wasn’t until I was slapped in the face with some cold, hard, objective data that I realized how wrong I’d been.

The Texas Study
These data came in the form of a study I recently worked on at the University of Texas.

In this study, nearly 100 initially sedentary participants either stayed sedentary (about half of them) OR began exercising (the other half). They exercisers were given a program to follow that added up to about 5 1/2 to 6 hours of activity per week and that lasted for a total of 12 weeks. The non-exercisers did nothing for the 12 weeks except show up for measurement sessions.

These individuals, as stated above, did no exercise before the study began. As a result of this sedentary lifestyle, they averaged between 35% and 40% body fat (according to DEXA scans).

Once the study began, the training group gathered together for 3 weight training sessions per week and 2 group exercise / interval sessions per week. All the training was designed by myself and overseen by a weightlifting coach and group exercise coach. So there was a pretty high level of quality control there.

Now, it’s important to note that we didn’t alter the participant’s eating at all. And we did this on purpose. We wanted to test the effects of exercise alone – without diet. In other words, the question became:

“Without a dietary intervention, can exercise alone reshape a person’s body?”

At the end of the 12 week study, we got our answer:

“Not so much…”

That’s right, when analyzing the data, I was shocked to find that even with 3+ hours of training per week with a weightlifting coach and 2+ hours of training per week with a body-weight circuit instructor didn’t really work. The formerly sedentary participants didn’t do much better than their couch-sitting counterparts.

That’s right, without dietary control, 12 weeks of high intensity training produced a fairly disappointing 1% loss of body fat. In terms of raw data, the participants lost only 1 pound of fat and gained 2 pounds of lean vs. the placebo group.

Frankly, that sucks.

The Machete Perspective
Now, imagine you’re overweight (about 38% body fat) and you decide to take the plunge, to hire a personal trainer, and to get in shape for perhaps the first time in your life.

So, you decide to buy a training package, one that contains 60 sessions (5 sessions per week for 12 weeks). The cost, per session, is 50 bucks, the going rate. So you plunk down 3 grand and start your initial 12 week fitness journey.

You don’t expect big things…you just expect to start moving in the right direction. So you’re patient. You attend all your training sessions, you get to know your trainer really well, spending over 60 hours with him or her. You stay off the scale, not wanting to jinx yourself.

Then, at the end of the 12 weeks, you weigh-in.

Body weight –
You were overweight, obese in fact, to start with. Well, if you simply exercised (without changing your diet and following the protocol above) you now weigh one pound more!

About to go crazy, your trainer talks you down off the cliff. You probably gained a lot of muscle while losing a lot of fat, he or she says. So it’s time to do a body comp test.

Fat weight -
Ok, here’s the moment of truth. You’re sure there must have been some fat loss. Drumroll please…

If you followed the protocol from above, you’re down one, uninspiring, unnoticable pound of fat.

“What the heck!? Can I NOW be pissed?”

Lean weight -
Because you weigh one pound more, and lost one pound of fat, that means that your formerly sedentary butt put on 2 lbs of lean mass.

That’s nice and all. But that wasn’t the goal! You wanted to lose fat. This is when your anger kicks in.

So, you spent 3000 bucks and 60 hours working your ass off in the gym. And your ass didn’t change one bit! Is it time to grab a machete and take that good for nothing trainer’s head clean off?

It’s Not A Fluke
Now, when I first saw these data, I thought they were a fluke. I got the research team together on the phone and chewed them out. There must have been a data mix-up.

I mean, seriously, 12 weeks of hard training and only one pound of fat lost vs. no training at all. Was this some sort joke? Did they screw up the data collection? Did the research participants skip out on sessions? What was the deal?!?

Despite my insistence, there were no errors. The participants showed up. They trained hard. The data were collected properly. The participants just didn’t progress. And, for the first time, I started asking the question honestly.

Can a solid training program alone get people into great shape?

Note I said “solid” training program. In the past I figured people weren’t getting results because their training program was awful and perhaps so was their diet.

But, as a result of this new study, a study in which the training protocol was solid, the answer appeared to be no. A solid training program alone wasn’t enough to get people into great shape.

Other Research Support
With a new sense of purpose, I started digging around in the research. And I quickly found another recent study suggesting the exact same thing.

This study, published in the April 2008 issue of Nutrition and Metabolism, demonstrated that after 10 weeks of training (3 endurance sessions and 2 strength sessions per week – the flip flop of our study), 38 previously overweight, sedentary subjects also saw minimal changes in body composition with training.

Body Weight –
In this study, neither the control (no exercise) group or the exercise group significantly changed their body weight. Both groups saw about a 0.6lb loss in body weight on average. But again, neither change was significant.

Fat Mass -
When it came to fat mass, the exercise group lost 2.4lbs while the control group lost 0.9lbs. This means that the 50 exercise sessions lead to a mere 1.5lb fat loss vs doing nothing. Better than a kick in the teeth, I guess. But not all that stellar.

Lean Mass -
The exercise group grained 1.7lbs of lean mass while the control group gained 0.2lbs of lean mass. This means that the 50 exercise sessions led to a 1.5lb gain in lean mass vs doing nothing at all. Again, not bad. But not great either.

Different vs. Important
Sure, in both studies, the changes were “statistically significant.” In other words, participants did lose more fat and gain more lean mass when training vs. not training. However, let’s not confuse different with important. After all, these changes are small, really small. And I would suggest, unimportant.

I mean, come on now, people exercise to actually change their bodies in noticeable, measurable ways. They want to fit better into their clothes. They want to go from overweight to normal weight. They want to be able to walk up the stairs without getting winded. They want to lower their cholesterol.

In my estimation, and it might just be me, they’re just not all that interested in dumping big dollars and lots of time into something that leads to a one pound fat loss. Seriously, that’s not all that good.

The Lesson – No, It’s Not To Stop Exercising!
At this point you might be wondering if it’s my advice to stop exercising. Of course not! Exercise is critically important to looking better, feeling better, and performing better every single day. And don’t you forget it!

However, my point is that exercise ALONE just doesn’t cut it. What you really need is exercise PLUS a sound nutritional program. Now that’s just what the doctor ordered.

Consider what happens when people actually eat well…

In our recent Precision Nutrition Body Transformation Challenge, the average fat loss for all of our participants was 1/2% (or 1lb) lost per week! Remember, in the studies above, they lost about 1 to 1.5lbs in 10-12 weeks!

That’s almost at 10-fold increase in effectiveness when people added the Precision Nutrition plan to their training system.

Further, our finalists (the top performers) saw the following results:

  • Finalist #1 lost about 30lbs in 16 weeks – losing 23lbs of fat, or about 1.4lbs of fat per week.
  • Finalist #2 – lost about 16lbs in 16 weeks – losing 23lbs of fat, or about 1.4lbs of fat per week.
  • Finalist #3 – lost 37lbs in 16 weeks – losing 27lbs of fat, or about 1.7 lbs of fat per week.
  • Finalist #4 – lost 25lbs during 16 weeks – losing 35lbs of fat, or about 2.2lbs of fat per week.
  • Finalist #5 – lost 37lbs during 16 weeks – losing 31lbs of fat, or about 1.9lbs of fat.

Note: each of our finalists followed one of the training programs available in the PN Member’s Resource Section (member’s only) and our nutritional guidelines outlined in the Precision Nutrition System.

Also consider the research study discussed above, the one published in Nutrition and Metabolism.

In this study, there was actually a 3rd group. And this group, in addition to exercising, supplemented each day with 2 nutrient-dense meal replacement supplements. Each supplement contained 300 calories, 5g fat, 25g carbs, and 40g protein and a host of vitamins and minerals. And while the exercise-only group saw small fat losses and muscle gains, the exercise plus supplement group, was a different story.

Body Weight –
The exercise+supplement group lost 4lbs of total body weight. This compared to the 0.6lbs lost in the exercise alone group.

Fat Mass -
The exercise+supplement group also lost 6lbs of total body fat. This compared to the 2.4lbs lost in the exercise alone group.

Lean Mass -
The exercise+supplement group gained about 1.8lbs of total lean body mass. This compared to the 1.7lb gained in the exercise alone group.

So, as you can see, even something as simple as adding a high quality protein drink or MRP can improve fat loss vs. exercise alone.

But, again, nothing is as effective as following a solid nutrition program while exercising properly.

Trainers Take Note
At this point, I’ve gotta serve notice to trainers. Folks, if you’re not providing nutrition advice to your clients, that’s a real problem.

A trainer selling a client exercise alone is equivalent to a car salesman selling a car with no engine. As you’ve already seen, the thing just won’t go.

Now, I don’t want to seem as if I’m taking shots at ALL trainers because I love the service many of them provide. However, I do have something to say to those trainers who don’t have a nutrition system in place.

Nutrition – Fit for an Athlete

October 16, 2008

For an athlete achieving peak performance is paramount particularly in the competitive world of athletics. Athletes perform at their very best when they undergo proper training and eat a balanced and nutritious diet. Whether you are a keen sports person or an athlete competing at the highest level, good fitness is necessary to maintain strength, fight infections and injuries and provide energy. Therefore let us examine the nutritional elements that make up an athlete’s diet alongside other tips worth considering.

An athlete’s diet is largely made up of carbohydrates known as complex and simple carbohydrates. Complex carbohydrates are found in foods such as cereals, pasta and potatoes and simple carbohydrates are in foods namely sugar, honey and fruit.

Complex carbohydrates are broken down by the body during digestion and turned into glucose which is then stored in the body as glycogen. During exercise the glycogen is converted back to glucose and used for the energy required to sustain prolonged and strenuous bouts of activity. It is important that an athlete’s energy levels are kept up during this time as a lack of it may well lead to fatigue and a weakened mental attitude, vital if he or she is to win and perform at their best.

Glycogen is a form of glucose. The body cannot store much glycogen although athletes need a lot of it. Therefore in order to keep the ‘glycogen tank’ full, try to eat carbohydrates as much as you can and drink plenty of water as glycogen is stored better when the body is well hydrated.

Try to avoid white sugar and honey as this increases the pain of injuries. Should an injury occur, get a fresh pineapple and eat as much of it as you can as it contains an enzyme called Bromelain, which helps the healing process by breaking down the injured tissue. Taking vitamin B6 is also good as it is a natural diuretic and helps carry damaged tissue out of the system.

A good diet which contains a variety of foods will ensure that an athlete gets sufficient vitamins and minerals. Vitamins such as Thiamin B1, Riboflavin B2 Niacin and Folacin maintain a healthy body and are found in foods such as whole grains, liver, lean meats, milk and green leafy vegetables. Calcium is also good for bone structure and strength and a lack of it can lead to osteoporosis later in life. A excellent supply of Calcium can be found in foods such as eggs, cheese and milk.

Iron serves an important part in the body as it carries oxygen to the red blood cells and removes carbon dioxide. Many growing athletes, women and vegetarians are prone to having an iron deficiency due to poor iron intake, low absorption or loss of iron in sweat. A diet sufficient in fruits, vegetables, cereals and red meat will help rectify any shortage.

The function of protein in the diet also provides a vital role. Protein is used for building and repairing muscle, bone, skin, hair and other tissues. It is essential in the diet as the body doesn’t store protein, the best sources coming from eggs, milk, meat and fish. In general athletes who train hard tend to need more protein than the average individual, and the amounts they need depend on the duration, intensity and frequency of the exercise. Athletes whose diet is low in protein may experience fatigue and poor performance.

Foods that contain fats provide fuel for the body and the amount of fat used depends on the athletes physical fitness and the event that he or she is competing in. Trained athletes tend to use up more fat than an untrained athlete. A good amount of body fat is needed and care must be taken when eating foods with a high fat content as it can lead to weight gain. Select lean cuts of meats and low fat dairy products along with ‘healthy’ fats and oils such as Canola and Olive oils.

Water is crucial in the life of an athlete and drinking 8-10 glasses of water throughout the day will ensure that you are replacing fluids loss during exercise. Dehydration can cause fatigue and muscle cramps. Drinking chilled liquids throughout the event is advisable as they lower body temperature.

Other tips to note are:-
•    Always eat breakfast as this will help kick start your day and your metabolism.
•    Do not eat any foods that you are not familiar with. An athlete doesn’t need any ’suprises’ on the big day. Experiment after the event and not before.
•    Any food eaten should be well digested before the exercise or event begins. The body must feel as light as possible. Leave 3.5 hours after eating a high carbohydrate meal and 2-3 hours after eating a big meal.

So for anyone who enjoys sports competing is only half the fun. Keeping your body in peak condition will not only benefit you in years to come but will ensure that you excel and win at your chosen sport. After all as the saying goes ‘You are what you eat’ a phrase that rings notably true in the world of athletics.
