"I lost 10 kilograms. There's no secret behind it, you just have to not eat and exercise," he claimed.

JungGiGo continued, "I also lost 15 kilograms while I was promoting "Some". I tend to eat a lot during my off seasons. Since I like to drink and enjoy hanging out with friends, I gain more weight during those times. That's why I don't meet with anyone when I need to go on a diet."
