On April 2nd, singer IU guested on MBC TV's "Quiz to Change the World". During the recording, she revealed her weight change since her pre-debut days. MC Park Mi Sun started off by stating, "IU is very popular amongst idol members" - noting that many have even picked IU as their ideal type. To this, IU sadly replied, "Maybe it's because of that, but in reality, not one person has contacted me." Park Mi Sun made a clever metaphor, "There's usually nothing to eat at a famous banqueting house" - drawing laughter from the guests. Just then, singer Hong Seo Bum interjected, "You have to watch out for Sul Woon Do." To which Sul Woon Do wittily replied, "She's not my ideal type" - causing the whole studio to burst out in laughter. Besides this, IU also drew attention as she revealed that she lost 10kg since her debut. Because of her busy schedule, her weight loss came naturally. When she began to receive compliments about becoming more womanly, she shyly replied, "I lost of lot of baby fat." Meanwhile, 2PM's Junho, Nichkhun, and Chansung; 5dolls' Chanmi and Eungyo; and comedian Ji Sang Ryul also guested for this episode. Source: TV Report via Nate
