Hi! I've lost weight too, a ittle more than 10 pounds at this point, and I'm not very big to start with. I think it is diet - no cow dairy and cutting way back on starches seems to limit what I can eat. Some of it could be AS I suppose. I don't want to lose too much or my clothes won't fit and I can't afford to go clothes shopping till after my boys graduate and get jobs. Good luck - Helen
