Still get healthy, even if the skin is hanging it's better than being unhealthy and overweight. I lost 50 lbs so far, there is some sag but with light therapy (light4beauty.com) deep tissue massage (with that wooden block) and vitamin C (5 bucks at Skinactives.com) the skin can look MUCH better, not perfect, not fitness model, but damn good for a 42 year old ex-fatitude -- it took years to stretch out, it will take time to go back too. And there is Thermage too.
