Blaha is pretentious. He has the Layne Norton quality that he acts like an expert (in Laynes case he may be one) but provides no reasonable proof. He makes claims about his build and strength that he can't back up.
These are a few of the many reasons.
What is he an expert on? This shit is not complicated. You read that one damn study in which bodybuilders from the 50's were studied, use the FFMI calculator, and then from that, say that people with an FFMI over 25 dieted down are likely to be drug aided. This does not take expertise. It's common sense coupled with observation and experience.
He says some shit here and there on training and nutrition, but he has not shown he is an expert. Even Layne has a Phd in nutrition and has said some shit about training and nutrition.
With that said, I like both of them anyway, and I met Layne earlier this year at a nutrition conference at a college. I work in nutrition myself.
