I've previously asked if the obesity "epidemic" in the United States is overstated. That said, there are a growing number of children and adults who are genuinely obese.
The New York Times has an article on weight loss camps.
Apparently, these camps are typically for profit. Scientists express concerns that children may revert to their previous weight after completing the camp. Health insurance typically doesn't cover the costs of these camps, and national lobbying is taking place to change that. All in all, the article highlights a quintessentially American set of challenges around organizing care for a (possibly overstated) medical condition.
