One of the boggest conceren fo people who have alot of weight to lose is excess skin and will they need plastic surgery, This is one of the MANY easons I haev for holding off on gastric bypass surgery or and WLS( weight loss surgery).
Interesting article here on The Myth of Loose : http://www.bodyfatguide.com/LooseSkin.htm
When I look at my body- expeciall the “apron” of fat and skin I really dont know what will happen to it or where it will go.
The article implies that increasing mucsle mass with ger rid of the excess skin- but I am dubious.

Non-Surgical Removal of “Loose Skin”
To eliminate the droopy appearance of the remnants of excess body fat following weight loss, without resorting to surgical procedures, you must change your body composition, not just lose bodyweight. That means paying particular attention to the ratio of your body fat to lean body mass. Gaining muscle to replace some of those lost pounds of body fat and preventing loss of lean body mass while dieting will dramatically improve your appearance.

It is possible to be at the ideal bodyweight according to Body Mass Index charts (BMI), but still have too much body fat and not enough lean body mass. For example, a young woman in her twenties with “loose skin” recently appeared on a popular radio talk show. She had lost over two-hundred pounds in one year, and her bodyweight at 5′ 8″ was now in the 120’s. Yet, her abdomen was covered with flabby skin that hung off of her. I would guess there is at least another 20 pounds of excess body fat stored in those folds of skin. However, if she lost another 20 pounds of bodyweight, she would obviously look like an emaciated stick! But, that’s not because she is too low in body fat…it’s because she lacks sufficient lean body mass!
