Losing substantial fat can be a life changing effect. Unfortunately, loose skin often plagues people after significant fat loss.

Someone who is younger is less likely to have very noticeable loose skin after losing fat, unless they are extremely obese. The older and longer you been overweight, the worse your excess skin will be when you lose the weight.

Luckily, over time the loose skin will slightly tighten up if you continue to maintain your smaller self. However, the only real way to completely get rid of loose skin in moderate to severe cases is with surgery.
