I have no advice for you, really, but I do know that my bf lost about 130 pounds before I met him, and he does have stretch marks and some loose skin around his belly and thighs. As far as he knows, the only way to get rid of it would be surgically, and I don't think that's worth it. He lost the weight fast (Atkins) and then starting exercising, but I think if you are exercising while you lose the weight, your body will tone up more and you will have less of a chance of that happening. Sorry I don't really have more advice for you; I would like to lose 30 pounds also, and if I end up with some extra skin, I think it'd be worth it! Good luck to you and let me know if you find anything out!
