is propanalol a beta-blocker? Beta-blockers make it a little harder for a person to lose weight. Also, given your height and weight and taking propanalol, i would worry about becoming light-headed from fasting, that your blood pressure might drop too low. Your size sounds just about perfect to me, i thought you had some muscle on you. I would just build more muscle and let that muscle burn off any extra fat. I think if you try to burn off fat, you will lose muscle instead and thereby lower your metabolism. Also, stressing out will shoot fat to your belly via cortisol, and you dont want that either.
