A friend of the family is considering going Primal/Paleo after seeing the weight I had taken off. However I only took off 42 pounds she wants to do 150+ pounds. Her concern is sagging skin. She had considered gastric bypass but a side effect is excess skin. A friend of hers at work who is supposed to be paleo is telling her that the skin tightens up on our type of lifestyle and she does not need to worry about the skin. She is asking me to confirm this. I honestly don't know.

Anyone with first hand experience that can help with that question? She is about 5' 3" and 280 pounds(my estimate).
