Diet self help books will just confuse you. I even find stuff on this site that are contradictory to each other. Find a health plan that works for you and stick to it. I chose to go more raw. I cook very little and don't heat my food over 118 degrees. I found recipes free on line and through facebook that are awesome and taste phenomenal. I chose to do HIIT over normal cardio. I find normal cardio extremely boring and the benefits only last while you are doing the exercise instead of like with HIIT, I am still burning fat 36 hours later. (I did the research)
Books aren't going to teach you what your specific body needs. I have found that most are geared to the standard american diet which I refuse to follow.
