Singer/actress IU revealed the secret diet plan behind her character’s weight loss in KBS‘s “Dream High” while walking reporters through the film set during the drama’s press conference on January 25th.

Fans immediately noticed a diet plan scrawled on the school’s blackboard amidst several other lunch menus for Chinese, Japanese, and Korean cuisine.

The special ‘diet menu’ consists of salad, a boiled egg, boiled sweet potatoes, and eight baby tomatoes, all amounting to exactly 346 calories.

Fans speculated this to be the diet plan used by IU’s character in losing weight for her transformation.  Although it’s certainly interesting to look at, they expressed their sorrow in ‘Pil Sook’ having to go through such a strict menu.
