Heirs star Kang Ha Neul revealed in a recent interview for Campus 10 magazine that during his high school years he had weight issues. He explained that he weighed over 200 pounds at one point, and in order to lose weight he went on various diets including a very strict one involving negative calorie foods.

I had a feeling negative calorie foods involved a lot of vegetables and fruits but there ended up being more to it than that. After researching on Web MD I found out that negative calorie foods are supposedly foods that "take more energy to digest than they provide in calories." So for example, the one lousy carrot stick your munching on may contain 5 calories, but your body burns more calories than that by having to work to digest it.

Kang Ha Neul obviously looks amazing these days but the whole negative calorie diet theory isn't actually proven to work the way in which it's said to work. Honestly, probably any diet that restricts certain foods and requires you to eat only fruits and vegetables will result in weight loss, but that doesn't mean it's safe. So even though Kang Ha Neul looks hot don't try to be him, just try to be with him. #WordsOfWisdom
