She revealed, "I never liked salty food.  I liked them when I was young, but I get bloated easily, so I don't eat them.  I also bloat a lot if I eat flour, so I don't eat it often.  I don't think gluten goes well with me.  I don't eat kimchi often, either.  When I was young, a teacher tried to regulate my eating, so I was forced to eat it; due to that trauma, I don't eat it.  I do eat things like kimchi fried rice, but if [the kimchi pieces] are too big, I take them out.

"I never starve myself to maintain my figure.  I fear that if I starve myself, there will be a yo-yo [effect], so I slowly and deliciously enjoy cooking that is healthy.  For exercise, I do core workouts that raise my basic metabolism rate."

Time to jot some of this down!
