SEVENTEEN’s Mingyu shocks fans with rapid 7 kg weight loss ahead of Dior show; shares intense 12-day routine

Mingyu

SEVENTEEN member Mingyu has once again captured the internet’s attention, this time not for his performances or visuals alone, but for the sheer intensity of his preparation for a recent Dior fashion show. Fans were left both stunned and concerned after learning that the idol reportedly lost a massive 7 kilograms in just 12 days leading up to the high-profile event.

The revelation quickly went viral across online communities, as fans noted the dramatic transformation in Mingyu’s appearance. Known affectionately for his softer, “dumpling-like” visuals at times, the idol appeared at the Dior show with noticeably sharper features, including a jawline that fans joked was “sharp enough to cut paper.” The stark contrast sparked widespread discussion about the lengths idols sometimes go to for major schedules.

Curiosity surrounding the transformation only grew until Mingyu himself addressed it directly during a livestream on January 31, 2026. During the broadcast, he openly shared details about the short-term but demanding regimen he followed in the days leading up to the show.

According to Mingyu, the weight loss was the result of a strict detox-focused routine that lasted nearly two weeks. “For 12 days, I did a detox while eating only seonsik. This cleansed my body. They told me not to exercise, but I did light cardio for 30 minutes daily. The weight just fell off,” Mingyu explained.

Seonsik, a powdered meal replacement commonly consumed in Korea, is often used for short-term dietary control or detox purposes. By relying solely on it for 12 consecutive days, Mingyu significantly reduced his calorie intake while still consuming basic nutrients. Despite being advised against physical activity during the detox, he admitted to incorporating daily cardio, at a lighter intensity.

While many fans expressed admiration for Mingyu’s discipline and professionalism, others voiced concern over the extreme nature of the routine.

Mingyu reassured fans that the regimen was temporary and specific to preparing for the fashion event. Following the Dior show, he confirmed that he has since returned to eating normally and prioritising rest and recovery.
