Just an example of losing weight too fast and the skin thing...

A friend of mine lost around 80 lbs between high school and college (I think she went from around 210 to 130 or so). She lost is really quickly, and even though she was pretty young, I think she just lost it too fast because her skin on her tummy never did shrink down to where it should be. That extra skin bothered her so much she wouldn't wear a bikini or revealing clothing even though her shape was really great. It all ended well though, since she got all of that extra skin tucked as a graduation present!
