I really want to order the P90x workout videos, but my only concern is the nutrition. The infomercials have said that following the nutrition guide is key to the success of the program. I know there is 3 sections of the guide and I should be eating different foods within those three parts. I was wondering if it tells me what i should eat and when i should eat. I don't want to purchase it and then not get results because I wasn't eating the right foods when I thought I was. If anybody has P90x and reads this can you please leave an answer.
