Bodybuilder's diet myths?

Stumbled across this article at Peak Performance. Controversial to say the least

What do you all make of it?

----------------------------------------------------------------------------------

Professional bodybuilders look great during competition, and most of them believe that their 'ripped' physiques are at least partially the result of their carefully planned nutritional programmes. However, new research carried out by Janet Brill at Florida International University indicates that most bodybuilders have weighted down their minds with a load of nutritional bunkum. At best, these faulty beliefs waste bodybuilders' money; at worst, they may actually make it harder to produce the rock-hard physiques which bodybuilders desire.

After surveying 309 male and female bodybuilders, Brill discovered that the following myths about nutrition were prevalent:
Myth No. 1: Protein supplements are necessary to build muscle mass. Fact: Whenever a bodybuilder lifts a weight during a workout, carbohydrate - not protein - provides the necessary energy. Therefore, large amounts of carbohydrate are required to carry out the strenuous training needed to stimulate muscle growth. The excess dietary protein which bodybuilders consume isn't funneled directly into muscle production; in fact, the builders' bodies actually convert extravagant quantities of protein into carbohydrate, which is then metabolized for energy.

Myth No. 2: Carbohydrate loading just before a competition helps to 'pump up' muscles. Fact: When carbohydrate (glycogen) is stored inside muscle cells, water is stockpiled, too, so this belief seems logical at first glance. After all, maybe that accumulated water could make muscle fibres swell up a bit. However, if carbo-loading really produced a 'maximum pump' marathon runners would have gargantuan arms and legs instead of their characteristically scrawny appendages. Indeed, scientific research has shown that carbo-loading doesn't expand muscle-cell diameters at all.

Myth No. 3: Carbohydrate loading stretches the skin, making muscles bulge. Fact: Carbo-loading doesn't broaden the muscles, so there's no extra pressure put on the skin. Also, carbohydrate isn't stored in the skin, so there is no reason for the body's outer covering to change in any way.

Myth No. 4: Consuming extra quantities of sodium increases muscle definition. Fact: The hypothesis is that the additional sodium will pull water into muscle cells, making the muscles expand, but there is absolutely no evidence that this actually happens. In fact, the extra sodium is usually simply dumped into the urine.

Myth No. 5: Sodium restriction increases muscle definition. Fact: Again, there's no supportive evidence, but this widespread belief, the exact opposite of Myth No. 4, gives a good indication of the nutritional confusion which prevails among bodybuilders.

Myth No. 6: Bodybuilding magazines are the best source of information about sports nutrition. Fact: Bodybuilding magazines can't survive on subscription sales alone; they need the advertising revenues which they receive from nutritional-supplement manufacturers. It's doubtful that bodybuilding publications will ever bite the hand which feeds them; after all, contradicting the unverified nutritional claims made by supplement makers could lead to a loss of advertising.

Myth No. 7: 'Growth-hormone releasers,' including amino acids such as arginine and omithine, are effective alternatives to steroids for enhancing muscle growth. Fact: There's no solid evidence that the releasers have an anabolic effect.

Not surprisingly, Brill found that only 1 per cent of bodybuilders get their nutritional information from registered dietitians. The same percentage of builders derive their dietary information from family members and friends - or from television! In contrast, about 50 per cent of all bodybuilders receive their primary nutritional advice from other bodybuilders, and 17 per cent rely on bodybuilding magazines. Overall, 'someone who has recently won a contest is viewed as a far more credible source of nutritional information than a nutritionist or an exercise scientist,' notes Brill.

How do bodybuilders look so great - when their nutritional beliefs are so flabby? Well, we'll have to let you use your imagination to resolve that strange paradox.
 
is that real? i never heard of a lot of those 'myths' before... some sound hella fake.... i think the reason lots of bb'ers listen to other bbers is cuz whatever they do obviously works, and the fat dieticians whatever they are doing, doesnt work, i would like to see 2 people do a test, one with bb diet, one dietician advice diet... see who bulks up faster... twins with the same genetics if possible... lol.

This was kinda my point in posting this.

It challenges a lot of what I beleve in terms of diet and such.

I was curious as to how others took it.

Thanks for the reply.
 
I'll tell you what that is...They said themselves the muscle mags are a business, and so is the medical field. Myth 1: Doctors love to act like they know more than anybody. Fact: I have talked to doctors that don't know the difference between glutamine and glucose (really).
Myth 2: The exercise creates the muscle so the more carbs the more muscle you build, Fact: it is not the exercise that creates muscle but recovery from damage that exercise does.
Myth 3: Carbo loading will pump up a marathon runner, Fact: they have nothing to pump up in the first place.

Man I hate these know it all Doctors

Now this is what I was looking for!!!
 
I am hardly a guru...but this article is long on speculation and short on substance. If it backed its shit up with evidence I wouldnt have a problem with it, but the fact is, even in BB mags there is far more attention to detail and research and citing sources than in this article.

As I said I am no guru I am actualy pretty ignorant, but here is my reply.

Myth No. 1: Protein supplements are necessary to build muscle mass. Fact: Whenever a bodybuilder lifts a weight during a workout, carbohydrate - not protein - provides the necessary energy. Therefore, large amounts of carbohydrate are required to carry out the strenuous training needed to stimulate muscle growth. The excess dietary protein which bodybuilders consume isn't funneled directly into muscle production; in fact, the builders' bodies actually convert extravagant quantities of protein into carbohydrate, which is then metabolized for energy.
BBers take protein not for energy to lift the weight, but for muscle growth and repair. Every single BBer I know eats huge carbs as well.

Myth No. 2: Carbohydrate loading just before a competition helps to 'pump up' muscles. Fact: When carbohydrate (glycogen) is stored inside muscle cells, water is stockpiled, too, so this belief seems logical at first glance. After all, maybe that accumulated water could make muscle fibres swell up a bit. However, if carbo-loading really produced a 'maximum pump' marathon runners would have gargantuan arms and legs instead of their characteristically scrawny appendages. Indeed, scientific research has shown that carbo-loading doesn't expand muscle-cell diameters at all.
Source for that last sentence? And, marathon runners train completely differently from BBers. It's a whole different world. Who knows, maybe a marathoner does get a small pump of his tiny muscles, when he carb loads.

Myth No. 6: Bodybuilding magazines are the best source of information about sports nutrition. Fact: Bodybuilding magazines can't survive on subscription sales alone; they need the advertising revenues which they receive from nutritional-supplement manufacturers. It's doubtful that bodybuilding publications will ever bite the hand which feeds them; after all, contradicting the unverified nutritional claims made by supplement makers could lead to a loss of advertising.
This is actually an excellent point. People should always beware of conflicts of interest. And no doubt most supplements are junk. That doesnt invalidate the BB diet though - you need scientific research for that

How do bodybuilders look so great - when their nutritional beliefs are so flabby? Well, we'll have to let you use your imagination to resolve that strange paradox.
...and therein lies the reason this article is idiotic.
a) no sources to check, no hard evidence, just hearsay and "a study said so-and-so" (WHICH STUDY!?!?!)
b) it fails to explain how BBers who follow her "myths" get so huge and look so good

1) Studies have shown pre and post workout protein to be highly beneficial. But of course protein powders aren't necessary, they are after all, supplements.

2) After all, maybe that accumulated water could make muscle fibres swell up a bit. You ever try to get a good pump going on a low carb diet? The runner comparison is off-base in so many ways.

3) See #2, if muscle fibers expand, skin will be tighter.

4) Never heard this one..

5) Sodium increases water retention, which is why you need sodium. Ever hear of all those guys dying from sodium deficiency by drinking tons and tons of water?

6) Yeah, I'll give them that one. Although, there are some good ones out there; I like T-Mag.

7) Yeah, free form aminos tend to be pretty useless. Although Arginine can increase NO2 levels, which can help with erections ;)
 
Considering that most dietitians I've come across look like shit and probably couldn't compete in either power-based or endurance-based athletics for shit... umm yeah anyways.

That's absolutely no indicator of their diet-related knowledge. It's like saying a big fat football coach (like mine, in high school, who coached us to 2 state championships) knows jack about football because he obviously can't play.
 
But who would you trust to teach you to be the best at your position, the Pro-Bowl MVP or the fat coach you described. I'd stick with the Pro and let the fat coach concentrate on the plays instead of my techniques. In bb terms your analogy would be like saying I should listen to good old Joe W. and ignore Coleman. Only experience can prove mastery of any skill...And spectating is not experiencing.
 
You ever see a pic of Lyle MacDonald? His body ain't shit-hot, but he's a genius when it comes to diet.
 
Myth No. 4: Consuming extra quantities of sodium increases muscle definition. Fact: The hypothesis is that the additional sodium will pull water into muscle cells, making the muscles expand, but there is absolutely no evidence that this actually happens. In fact, the extra sodium is usually simply dumped into the urine.

IMO - the body always aims for homeostatis and once the blood levels of sodium are elevated the kidneys will simply not reabsorb the extra sodium into the blood and exrete it in the urine. One the other hand, if the sodium is persisitanly introduced perhaps the sodium will cause some water (cause sodium and water travel together) retention..... but this wont give the definition, just bloat

Myth No. 5: Sodium restriction increases muscle definition. Fact: Again, there's no supportive evidence, but this widespread belief, the exact opposite of Myth No. 4, gives a good indication of the nutritional confusion which prevails among bodybuilders.

This one is plain stupidity IMO<,, Of course decreasing the sodium will give more definition. less sodium = less water.. = more definition.. why the hell do they think bb's use diuretics??? :p
 
In my physical fitness class, we discussed a similar article, it was proven that protein wasn't needed as much as carbs, i said "BULLSHIT" and got funny looks, i think they are crazy, everyone takes protein, any one that doesn't, is out of their mind, protein makes muscle gain...end of story!

Athletes who eat the recommended 50g of protein a day will have a very negative nitrogen balance. Regardless of calories. What does this mean? It means your body it eating its own protein.
 
You guys are right. It was a non sequitur on my part.

So let's look at this:

Myth No. 1: Protein supplements are necessary to build muscle mass. Fact: Whenever a bodybuilder lifts a weight during a workout, carbohydrate - not protein - provides the necessary energy.

FACT: The higher protein intakes are primarily for the purpose of muscle repair in between workouts rather than energy during workouts. And more than one study has shown the protein needs for bodybuilders and anyone who doesn't sit on their ass all the time to be higher than the RDA.

Myth No. 2: Carbohydrate loading just before a competition helps to 'pump up' muscles. Fact: When carbohydrate (glycogen) is stored inside muscle cells, water is stockpiled, too, so this belief seems logical at first glance. After all, maybe that accumulated water could make muscle fibres swell up a bit. However, if carbo-loading really produced a 'maximum pump' marathon runners would have gargantuan arms and legs instead of their characteristically scrawny appendages. Indeed, scientific research has shown that carbo-loading doesn't expand muscle-cell diameters at all.

FACT: Low-carb glycogen-depleting diets reduce inches off of most people's measurements in short periods of time. Marathon runners typically have far smaller muscle fibers even than your average human let alone your average bodybuilder.

Myth No. 3: Carbohydrate loading stretches the skin, making muscles bulge. Fact: Carbo-loading doesn't broaden the muscles, so there's no extra pressure put on the skin. Also, carbohydrate isn't stored in the skin, so there is no reason for the body's outer covering to change in any way.

FACT: Many people with reasonable sized muscles look and measure larger at the end of a workout/flexing session which followed a period of carb loading versus a workout session which followed a period of carb depletion. It is noticeable even to people who aren't familiar with common bodybuilding practices.

Myth No. 5: Sodium restriction increases muscle definition. Fact: Again, there's no supportive evidence, but this widespread belief, the exact opposite of Myth No. 4, gives a good indication of the nutritional confusion which prevails among bodybuilders.

FACT: No studies, but plenty of PRACTICAL supportive evidence.
