My brother is an engineer. One of the guys that worked with him was a very serious vegetarian Did all the things about replacing fats with this or that veg protein, with other more complex etc. he had it down to science and according to RG he stayed right at 2% body fat , ran marathons and was all lean muscle. One day RG spotted him in the lunch room eating a HAMBURGER!!
Carl, what happened? "You know I did that for 7 years". ""you have any idea just how hard it is to get your nutrition right on a vegan diet"? "It's work" "After 7 years I just decided it wasn't worth all the trouble and if I die a couple years earlier and enjoy myself, so be it".
