Okay First off I am 18... I did P90x, and during the 90 days I was on a strict diet the whole time, and after I finished I had one day where I ate anything I wanted and howerever much I wanted, Literally had a jar of Peanut butter in one hand, with cookies, chocolates, and Pizza in the other for basically the whole day. I went all out. The next day I returned to my normal healthy diet, and I started Insanity the following week. Well I am about to start my second month of Insanity, and Im wondering if its okay to go all out for a whole day like that again when I finish. I dont want my results to be effected, because at the rate Im at I should have my long wanted 6-pack after I finish Insanity. If I get my Abs showing the way I want, I never want that to go away, EVER! I plan on maintaining the same healthy diet after Insanity, mabey a little more leaniant because right now I am really hardcore. And will probably do a Fusion of Insanity, and P90x. I wanted to know how often would it be okay to have one of those days where I eat literally everything I want and however much I want without it effecting my hard work. Is it even okay to eat like that for a whole day? I just wouldnt want to unknowingly ruin my hard work.
