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.
