After you use this program to loose weight, what kind of long term dietary intake are you planning? Are you expecting to go back to eating what you used to? If that is the case why wouldn't you expect to simply gain back the weight again?
Permanent weight loss seems to require a permanent change to one's lifestyle. As such learning to eat properly in both type and quantity from the very beginning seems to be a good idea. Given such ideas, please consider just what this diet gimmick your considering does to the long term goal of permanent weight loss.
