That day, BIBI stated that she controlled her diet for two weeks ahead of the Waterbomb 2026 stage. Her manager explained to Lee Seo Jin and Kim Kwang Kyu that BIBI had to fast until the performance.
BIBI said, “I lived on chicken breast, eggs, brown rice, and soy milk. I focused on a protein-centered diet. After the performance, I plan to eat Korean beef intestines and spicy chicken feet,” talking about the diet management leading up to the stage.
Before the performance, BIBI visited the waiting room and packed snacks prepared by the organizers into her bag. She said, “I’ll eat these later when I go out for a meal,” carefully saving the snacks she couldn’t eat immediately.
Then, BIBI said, “Eating is the best thing in the world for me.” When Kim Kwang Kyu asked, “Are you someone who doesn’t gain weight no matter how much you eat?” BIBI unexpectedly shared her past.
She honestly revealed, “I used to be a chubby girl. I was the heaviest in middle school, about 155 cm tall and weighed 66 kg. It was impressive. This weight loss is really the result of effort.”
