Am reading the book and am now confused after reading a few threads about bodybuilding on here, I thought the whole idea of PB is not to eat foods like rice etc and stick with meat, veg, fruit and fat. Can a skinny guy NOT bulk up with the PB diet??? How did the cavemen do it? They didn't have rice and wheat. I've tried the conventional bodybuilding diets eating heaps of wholegrains, some meat, heaps of veg, fruit and some fat, don't get bigger, just end up with uncomfortable digestion, bloating and abdominal fat...
