The topic of diets came up on SBS' food variety show 'Baek Jong Won's Three Great Emperors', and Nara was able to have a taste of delicious Korean pancake. Her fellow guests were curious how the Hello Venus member manages to stay in safe, and she delved into her past, saying, "When I was young, I was really fat. It was to the point I had trouble breathing."

Nara continued, "My dad thought it had gone too far, so he took me hiking early in the mornings. I walked up the mountain with sand bags attached to me."

Well, it definitely worked!
