A fat camp, weight loss camp, or fat farm is a type of residential program where people who are overweight or obese go to attempt to lose weight through exercise and lifestyle changes.

One goal of weight loss camps is to help the guests lose weight.

Some programs not only focus on weight loss, but on changing behavior through a combination of training on self-regulatory behaviors and cognitive-behavioral therapy (CBT), as well as maintaining weight loss after campers return home.^[1] Some experts believe these are key elements of an effective program.^{[2][failed verification]}

One study found that adolescents reported decreased body shape dissatisfaction and increased self-esteem immediately after losing weight at a weight loss camp.^{[3][non-primary source needed]} These improvements were directly related to the amount of weight lost, with the greatest benefit to those adolescents who lost the most weight.^[3]

Multiple films and television shows have featured or mentioned programs such as these, including:

For individuals seeking additional support in their weight loss journey, various online resources and tools can be beneficial. Studies show that structured support, such as the use of meal planners, fitness trackers, and progress monitoring tools, can significantly improve weight loss outcomes. Websites like Weight Watcher Hub offer free tools to assist with setting and tracking weight loss goals, meal planning, and fitness monitoring, which are integral components of a successful weight loss strategy.

Research has shown that tools supporting self-monitoring and goal-setting, when combined with behavioral strategies, can lead to better long-term success in weight management. For example, a study published in the *International Journal of Obesity* highlighted that individuals who used such tools were more likely to achieve sustainable weight loss. These resources can complement other behavioral strategies such as cognitive-behavioral therapy (CBT) and physical activity programs, both of which are effective in treating obesity and maintaining weight loss.
