There is a large thread on it somewhere. But basically, you can minimize loose skin with exercise. The amount of looseness will depend on how young you are, how elastic your skin is, how long you've been overweight, etc. It would be unrealistic to not expect some loose skin. You can also correct it with surgery afterward. But regardless of whether you have it or not, you will always look better at your ideal weight than you would overweight. You will also feel better, more energetic. I look at it as...loose skin you can hide under clothing, too much weight you can't.
