very rarely,someone joins who has a legitimate lose skin problem where exercise alone will not help and surgery is needed,but on most occasions,people who think that they have lose skin and are planning surgery,don't actually have it,what they have is more fat to lose,those are people who have been dieting so long and lost so much weight,they weren't aware that there is a little bit more dieting to do and more weight to be lost,so please when in doubt don't rush to the plastic surgeon,come in for my opinion.
