Don't give up. I found that the program works and teaches you how to eat right. I found that my taste for food changed. When I cheated the foods I used to eat tasted greasy,yuky,So at that time as with others it even inforced in me that the program works and I should stick with it always.
So far lost 70 LBS need more to go but will make it for sure. No way can I turn back.
Stay in there and give it a longer try,let your body get used to the eating difference.
