Although you are never supposed to ask a woman how much she weighs, DJ Choi Hwa Jung did not shy away from the question.  He said, "Kahi, your body figure is so pretty.  How much do you weigh?"

Kahi replied, "My height is 168 cm (5' 5") and my weight is 49 kg (108 lbs)."

She continued, revealing the diet she undergoes to prepare for comebacks, "I really enjoy eating so I eat seven meals a day.  However, a month before my comeback, I exercise daily in order to maintain my figure . . . After six in the evening, I do not eat and in the morning, I have one banana.  Also, I only eat Korean food."
