Here is a very long and informative thread in the Maintainers Forum which we started in 2004 and have been "growing" since. My story is one of the originals in there. I lost and have maintained a loss of 65 pounds for 10 years. Yes, I did have skin removed. I carried ALL my fat around my belly. I was 45 years old when I started my weight loss and while my skin was in pretty good shape, the skin on my stomach had been "shredded" from 2 huge pregnancies. I'm absolutely positive that most of my skin issues were from the pregnancy damage rather than the weight loss. I can tell you that time has helped. I exercise like a maniac and have good musculature- but lowering my body fat further produces more loose skin, not less. Especially on my face. But at my age, everyone has some wrinkles unless they have been botoxed into rigidity.
Don't let fear of skin stop you- you can disguise it with clothes or have surgery if you can afford it and the idea doesn't bother you. I'm thrilled that I did, but I needed it whether I'd been heavy and lost or not.
