Well back then they said it worked by limiting the amount of food you can ingest but you could eat anything you wanted. They've now changed that. I can't eat very much in one sitting (never could really) but I am frequently hungry in a couple of hours. They did an x-ray and everything is fine on that end. They blame me. The more I read about it, the luckier I feel. So many people either die or have hideous consequences. I just gained back a good part of the weight. Though I never did lose a tremendous amount in the first place, I did lose a bit. I didn't get sick or lose my hair, etc. I'd rather be fat than dead.
