Depending how much you have to go down before the weigh in another option could be to check out the Stillman's plan. I don't have any experience with it, but many report alot of success. It also is higher protien so it would be muscle sparing and not have the health risks associated with the fat fast.

Potatofree - I agree, and think the fat fast is way over used and abused in most cases. If it came down to the person is going to do it one way or another it could kill them the slowest at least. I like the other kids are doing crack line though. That's when you pat the kid on the head and explain that is why the other kids will grow up to be cashiers at mcdonalds still and living with thier parents at 40. That threat should scare any teen.
