I have a fair bit of weight to lose. Whilst I would love to weigh less regardless, the saggy leftover skin is a worry to me. Is it possible to lose a lot of weight and not have saggy skin? I am only young (22), and I have read that this is when the skin is the most elastic. Has anyone here lost a heap of weight (say 80lb) and not had the skin problem? How overweight would one have to be before the saggy skin becomes inevitable?
