Singer IU confessed that she gained some weight since previously revealing her weight to be 44.9 kg. (99 lbs) on a July broadcast of SBS 'Strong Heart'.

Although fans know IU to have an extremely slim figure, she revealed on the most recent recording of MBC's 'Strongest Quiz Show Q' that she actually has a lot of stomach fat and now weighs 46 kg (101 lbs).

IU's confession had arisen because of celebrity personal trainer Sean Lee who said, "I can accurately guess a person's weight by just looking at their bodies." Sean Lee guessed IU's weight to be less than her actual weight as he stated, "IU looks to be 43 kg (94 lbs). At most she probably weighs 45 kg (99 lbs), but nothing more."

However, IU corrected him by stating, "No, I actually weigh more. I'm 46 kg. I have a lot of weight where you can't see it. If you don't believe me, I'll show you."
