Go Jun Hee opened up about what she thinks is her major flaw, saying, "I can't stand it when I'm hungry. Even when I'm in the car, I'll stop by a convenience store to buy kimbap if I'm hungry. I get really angry when I'm hungry."
When asked about her lean figure, the actress explained she had her own way of keeping the pounds off. She said, "I'm the type to gain weight easily, but if I eat a little bit at a time often then I gain less weight. I eat about 4-5 meals a day, but I avoid anything made of flour or anything fried. I tend to eat Korean food."
