Singer IU, 20, appeared on KBS2 Entertainment Weekly‘s Guerilla Interview. On the show, she went ahead and quickly expressed how what she worried about most of the time when it comes to herself was her diet.

On the regarding episode, when she was questioned what she’s most concerned about facing her comeback, she replied that it was her weight saying, “While filming the drama The Best Yi Sunshin, I gained a lot of weight.” As you already know, the Korean media industry is very particular about weight when it comes to their acts so IU's concern could not have been more than valid. During her drama, she gained more weight than she had anticipated and because of that, she got herself on a diet to shed the weight before her comeback was to be put into play.

Upon hearing IU’s concern, viewers found a clip of IU mentioning her dietary rules on SBS’s variety program Strong Heart. She had said during this guest appearance that, “In the morning I eat an apple, in the afternoon a sweet potato and a bit of water, and protein shake for dinner.” IU also revealed her height and weight on the show as 161.7cm and 44.9kg.
