Karina, who loves to eat, confessed she has a body type that gains weight quickly and loses it just as quickly.

She surprised the panel by revealing that she once gained 4 kg and lost 4 kg in the same day.

(During trainee days) I ate whatever I wanted, but when I weighed myself, I gained 4 kg. I had a weigh-in the next day, so I quickly lost the weight.

She also shared the method she used to lose the weight.

I turned on the heater in the practice room, put on leggings and a sweatsuit, a hoodie zip-up, and a padded jacket, and ran for five to six hours until 100 songs were finished. I also took a bath for an hour when I got home.

Hearing this, MC Ahn Jung Hwan stated, “You were draining all the water out,” noting that it was similar to the weight-loss methods used by athletes.

Doing this makes you feel totally drained. Now that I’m older, I can’t eat like that or exercise like that. These days, even rainy days make my body hurt.
