Question for those of you who have tried the Atkins diet?

If you lose body fat, does your skin sag, or does the outer layer of skin that is curvaceous shrink in size? For example, if a 300 pound woman, lost 200 pounds, do you think they could have the same figure as a model who is skinny, or would they hav extra baggage of skin lying around? I'm talking exlusively about the atkins diet. If you are not familiar with it, please do not answer.
