There are many different kinds of obesity boot camps, with different focuses and strategies. But in general these are sleep-away camps often for people who are considered morbidly obese, in which a controlled environment is provided in order to lose weight. There are camps both for children and adults. The effectiveness of these camps often depends a great deal on the camper's commitment to their own weight-loss/health improvement and the support of their family and friends. Weight loss camps are not cheap, and can cost up to $8,000+ per month, on the high-end. As for whether or not the camps would be covered by insurance, that is something that you would need to discuss with your particular medical insurance carrier in order to get the specifics.
