I got P90X over the summer and started to do it, but quit due to being gone on vacation and such. I know following the nutrition plan front to back is supposed to get you mind-blowing results, but I really cannot afford most of the stuff mentioned in the guide. All I want to know is what are the best foods to eat throughout the day while doing P90X, that will get me as close to the results as possible? Feedback will be greatly appreciated. Thanks!
