Before you start claiming that bodybuilders and Arnold are Atkins people, you should know something about a bodybuilders diet.
Body builders go thru several phases of diet when training for a contest.
It is only in the last phase, 12 weeks from a contest, that carbs are limited. But they are never elimiated.
At the lowest, carbs are dropped to one gram for every pound of weight. So a 200 pound athlete will drop at the lowest to 200 grams of carbs in pre-contest training. But most bodybuilders never even drop to that level. They choose instead to burn the fat off doing cardio.
But in the off-season, the muscle building time of the year, carbs are a HUGE part of a body-bulders diet. A 200 pound man will consume 400 to 600 grams of high quality carbs.
This is nowhere near the Atkins Diet of no carbs. If a body-builder did Atkins he may lose fat for a contest but would also lose muscle, making him so flat that he would not be able to sustain a pump on stage.
This is probably more than you wanted to know about a bodybuilders diet, but it is important to know before anyone believes that Arnold followed an Atkins diet to win the Olympia seven times.
Yesterday Dr. Dean Edell said on the radio that by curent BMI standards Arnold would be considered "obese".
From the pics I have seen he is in the "extraordinarily fit" category.
