Sixteen-year-old Zhu Lei successfully lost 109 kilograms (240 pounds) in nine months in a weight-losing camp.

The overweight teenager, who weighed 217.5 kilograms (479.5 pounds), signed up for the program last summer at his home in Changchun in northeastern China's Jilin province.

At the camp, medical experts design specific weight-losing plans for each participant, which include methods like acupuncture and psychological consultation.
