China has established 'fat prisons,' specialized camps designed for significant weight loss, accepting individuals from around the world. These facilities, often affiliated with commercial enterprises or the government, enforce rigorous training, mandatory weigh-ins, and restricted movement. Participants engage in activities like boxing and cardio, with banned items including instant ramen. An Australian woman documented her experience in one such camp, highlighting the strict security measures and the program's aim to encourage substantial weight reduction in adults and children.
