Participants in the "Biggest Loser" reality TV contest are able to shed massive amounts of weigh — frequently, 100 pounds or more. But followup studies indicate that maintaining that sizeable loss isn't a piece of cake, because often the body's metabolism fights back.

Bariatric surgery is currently the most effective means of weight loss for the extremely obese; some types have even been shown to cause remission of diabetes. But these benefits occur with some downsides, which people should be aware of before choosing this type of treatment.
Bariatric surgery is perhaps the most effective means of combatting obesity, and according to the Journal of the American College of Surgery, some form of that surgery was chosen by over 120,000 people in 2008. There is, however, more than one type of bariatric surgery, and until recently it wasn t clear which would be better in terms of post-operative complications, the rate of re-hospitalization, or the efficacy of different procedures.
Two recent reports raise hope that both bariatric surgery and drug treatments can be effective in helping obese individuals cope with the rigors of weight loss.
