A young Chinese couple, each weighing about 200 kilograms, has caught national attention as they fight to lose weight in preparation for their first child.

Lin Yue, 29, and his wife Deng Yang, 27, are undergoing weight loss therapy at a hospital in Changchun, Jilin province, which offered them free services.

The treatment started in late November and includes a diet and exercise routine, and traditional Chinese therapy such as acupuncture and massage, said Yu Shuzhong, the doctor working with the couple.
