Xiumin of EXO-CBX discussed his failed attempt at weight loss during a live broadcasting stage. 

During the group's debut broadcasting program through Naver's 'V' on October 31, Xiumin talked about how one should exercise while trying to lose weight. He stated, "When I was doing 'Growl' promotions, I weighed 53 kg (116 lbs). I didn't eat to lose weight. I ate one meal every other day, and just drank coffee all the time."

The weight loss didn't last long, however. Xiumin continued, "When 'Growl' was over, I got my chubby cheeks back in the next promotion. I gained 10kg (22 lbs) in 2-3 months. Yo-yo happens quickly. I do not recommend to skip eating to lose weight."
