Soyu and JungGiGo, who recently released their duo song "Some", appeared on the February 18 edition of�KBS' radio program 'Jo Jung Chi and Ha Rim's 2 O'Clock' and talked about their eating styles. JungGiGo also mentioned how he diets.

DJ�Jo Jung Chi said to Soyu, "I feel like there's nothing you can't eat," to which she replied, "There are foods that I haven't tried yet and there are foods I don't eat. I can't eat certain soups. I do enjoy Korean food. And it is true I do eat mostly everything, but I don't like foods that have a strong smell."

JungGiGo said, "I really have a mixed diet. I eat whatever I'm given. I even eat expired things." The DJs joked, "Then do you eat things that fell on the floor too?" Unexpectedly, JungGiGo responded, "I do," making everyone laugh. Soyu said, "I eat while savoring the taste, but JungGiGo just finds everything tasty."

In addition, JungGiGo divulged his secret to losing 15 kg (~ 33 lbs). He first revealed his reasons for dieting, "I did it to live like a person. I always liked eating and am the type to gain weight. When I'm not promoting, I eat and play severely, but I'm the type to quickly lose weight when it becomes time to promote again... You can't tell [I gained weight] based on my outer appearance. I don't gain much weight in my face."

He then revealed his personal method, "This is a method that everyone already knows, but I don't eat a lot and I exercise. It was the regular method. I don't hang out with people. If I meet people, I end up eating. When I wake up in the morning, I go on the running machine on an empty stomach and then eat little like two bananas and tofu for about a month and a half to two months. I was almost at critical condition. As I starved myself and only got rid of body fat, I lost even more muscle."
