46-Year-Old Leading Singer Reveals Weight Loss of 10kg (22 Pounds) in 2 Months

Sung Si Kyung is raising eyebrows with his extreme diet confession.

The singer posted on March 20 about his strict food routine. For a month, he ate only eggs, sweet potato, flounder sashimi, and supplements. He kept intense workout sessions, training up to three times a day while filming A Gourmet Friend’s Restaurant.

“I didn’t even count the one hour of walking and running cardio I do at night. During filming for A Gourmet Friend’s Restaurant, I worked out three times a day. For the first month, I basically lived on eggs, sweet potatoes, flounder sashimi, and supplements,” Sung said alongside his workout log.

He started at 95kg (209.4 lbs) on January 6 and dropped to 85.3kg (188.1 lbs) by March 15. That’s a 9.7kg (21.4 lbs) loss in just two months. He rarely rested, playing tennis and lifting weights regularly. His BMI hit 24.46, which is within the normal range—a big deal for a 46-year-old.

Sung Si Kyung explained,
“I’d been living as an overweight middle-aged man for too long, and at this age and weight, becoming a cosmetics model felt a bit shameless. But I saw it as a good opportunity and decided to put in the effort. People keep asking if I’m sick, but I was the one who wasn’t healthy before. Now I’ve finally reached a normal weight for the first time, so from here on, I’ll manage myself well and take better care of both my body and mind.”

Fans have mixed reactions about the diet’s intensity and sustainability.

Sung Si Kyung remains a popular singer and variety star, drawing attention with his recent transformation and candid sharing of his health journey.
