Singer Sung Si-kyung (46) revealed he lost 10 kilograms over about two months.

Posting on his social media, Sung shared, “I started at 95 kilograms on January 6 and lost 10 kilograms over about two months.” On how he did it, he said, “I didn’t log my nighttime cardio―an hour of walking and running―but during filming periods I trained three times a day,” adding, “For the first month, my meals were mostly eggs, sweet potatoes, halibut sashimi, plus supplements.”

He continued, “I’d been on the chubbier side for too long, and at my age I was offered a cosmetics modeling job, so I felt a sense of responsibility. I treated it as a great opportunity and worked hard.” Addressing fans’ concerns about his health, he added, “I was the one who hadn’t been well―now I’m at a normal weight for the first time. I’ll take even better care of my body and mind going forward.”
