I just lost 25lbs. On weight watchers. You eat regular food and you loss slowly. 1or2 lbs.a week. But you won't gain it back. Those fast weight loss diets are a disaster for me. I gained all my weight back on Jenny Craig . Do it slow and do it right. You chance of keeping it off is better inthe long run. If you want more info you can send me a message. Barb
