Weight loss camp
（重定向自Health farm）
A weight loss camp, weight loss resort, retreat, or holiday, is a type of residential program where people who are overweight or obese go to lose weight through exercise and lifestyle changes. In common parlance the term "fat camp" is also often used (either humorously or pejoratively) to refer to these programs. Weight loss camps typically provide nutrition classes, weekly weigh-ins, and a variety of classes and activities designed for weight loss.
