Demonstrating that it's not just the ladies who have to undergo an exacting diet, 2AM's Changmin revealed his own rigorous diet to his fans via Twitter. On December 4th, a screencap of his diet plan on his iPhone was uploaded onto his Twitter. Changmin wrote, "My diet plans starting tomorrow. Anyone want to do it with me? lol Am I starting up again?" His strict regimen is as follows:

Breakfast: multi-vitamins, 1�medium sized�sweet potato, low fat milk, 1 whole egg, 2 egg whites Lunch: 1 pack of chicken breast, 1 medium sized sweet potato, salad without dressing Snack: 4egg whites, half of a sweet potato Dinner: 1 pack of chicken breast OR 7 egg whites (and a salad if dying of hunger) After exercising, half of an apple and one scoop of protein

No idea how long the man can survive off his egg-and-sweet potato diet, but best of luck to him! (So long as it's healthy and nourishing, of course). Source: Hankyung
