What about the fact that bodybuilding is dominated by the carnivore lifestyle? Bill Pearl says that after going vegetarian, he had the same amount of muscle that he did when he won his Mr. Universe titles. Kenneth Williams, a vegan bodybuilder, placed third in the 2004 Natural Olympia bodybuilding competition. And, of course, Mike Mahler is long time vegetarian and strength coach extraordinaire. The fact is that, if you desire, one can easily build a massive physique while on a vegetarian or vegan diet.
