What quick, easy, non surgical ways to lose weight are there?

Anonymous
Basically the question says it all. I need to lose 30pounds for medical reasons I've been exercising and dieting with no luck and my doctor is pushing surgery which I don't want. I swear to God this is not an anorexic thing but if I can't get the weight off in the next three months I'm going to have to do what I don't want to do...the surgery. if I have the surgery to reduce my weight then I have to wait a further 4 months to have a valve transplant and even though it can probably wait I already have the date for the heart surgery set and I'm kinda too stubborn to change it
