"Nutritional Myths that Just Won't Die: Protein!"

So for a 200 pound guy that would be 200 grams of protein per day. No sweat. So how does this advice fair with the above current research findings? Well let's see. Being scientists like to work in kilograms (don't ask me why) we have to do some converting. A kilogram weighs 2.2lbs. So, 200 divided by 2.2 gives us 90.9. Multiply that times 1.8 (the high end of Dr. Lemon's research) and you get 163.6 grams of protein per day. What about the nutritionists, doctors, and others who call(ed) us "protein pushers" all the while recommending the RDA as being adequate for athletes?

Lets see. The current RDA is 0.8 grams of protein per kilogram of bodyweight: 200 divided by 2.2 x 0.8 = 73 grams of protein per day for a 200lb person. So who was closer, the bodybuilders or the arm chair scientists? Well lets see! 200g (what bodybuilders have recommended for a 200lb athlete) - 163g ( the high end of the current research recommendations for a 200lb person) = 37 grams (the difference between what bodybuilders think they should eat and the current research).

How do the RDA pushers fair? Hey, if they get to call us "protein pushers" than we get to call them "RDA pushers!" Anyway, 163g - 73g = (drum role) 90 grams! So it would appear that the bodybuilding community has been a great deal more accurate about the protein needs of strength athletes than the average nutritionist and I don't think this comes as any surprise to any of us. So should the average bodybuilder reduce his protein intake a bit from this data? No, and I will explain why. As with vitamins and other nutrients, you identify what looks to be the precise amount of the compound needed for the effect you want (in this case positive nitrogen balance, increased protein synthesis, etc) and add a margin of safety to account for the biochemical individuality of different people, the fact that there are low grade protein sources the person might be eating, and other variables.

So the current recommendation by the majority of bodybuilders, writers, coaches, and others of one gram per pound of bodyweight does a good job of taking into account the current research and adding a margin of safety. One things for sure, a little too much protein is far less detrimental to the athletes goal(s) of increasing muscle mass than too little protein, and this makes the RDA pushers advice just that much more.... moronic, for lack of a better word.

There are a few other points I think are important to look at when we recommend additional protein in the diet of athletes, especially strength training athletes. In the off season, the strength training athletes needs not only adequate protein but adequate calories. Assuming our friend (the 200lb bodybuilder) wants to eat approximately 3500 calories a day, how is he supposed to split his calories up? Again, this is where the bodybuilding community and the conservative nutritional/medical community are going to have a parting of the ways... again. The conservative types would say "that's an easy one, just tell the bodybuilder he should make up the majority of his calories from carbohydrates."

Now lets assume the bodybuilder does not want to eat so many carbs. Now the high carb issue is an entirely different fight and article, so I am just not going to go into great depth on the topic here. Suffice it to say, anyone who regularly reads articles, books, etc, >from people such as Dan Duchaine, Dr. Mauro Dipasquale, Barry Sears PhD, Udo Erasmus PhD, yours truly, and others know why the high carb diet bites the big one for losing fat and gaining muscle (In fact, there is recent research that suggests that carbohydrate restriction, not calorie restriction per se, is what's responsible for mobilizing fat stores). So for arguments sake and lack of space, let's just assume our 200lb bodybuilder friend does not want to eat a high carb diet for his own reasons, whatever they may be.

What else can he eat? He is only left with fat and protein. If he splits up his diet into say 30% protein, 30 % fat, and 40% carbs, he will be eating 1050 calories as protein (3500x30% = 1050) and 262.5g of protein a day (1050 divided by 4 = 262.5). So what we have is an amount (262.5g) that meets the current research, has an added margin of safety, and an added component for energy/calorie needs of people who don't want to follow a high carb diet, hich is a large percentage of the bodybuilding/strength training community. here are other reasons for a high protein intake such as hormonal effects (i.e. effects on IGF-1, GH, thyroid ), thermic effects, etc., but I think I have made the appropriate point. So is there a time when the bodybuilder might want to go even higher in his percent of calories >from protein than 30%? Sure, when he is dieting.
