This may sound ignorant, but does anyone else think Genetics play a larger role than diet? I'm not saying Diet isn't important, but there was a thing on tv a few weeks ago about this guy who eats 2 Big Mac's everyday for lunch and he only weighs 160lbs. I'll be honest here, my diet isn't that great. I eat as much pasta and bread as I can get. Last night I had about 8 manicotti for dinner along with chicken parm. But I'm still in pretty damn good shape...maybe because I train my ass off.
I guess for people who compete diet is crucial, but I still think a person's genetics play an equal factor.
