I just read some articles that Korean peoples more healthy. Their obesity level so low than other Asian. That's why idol from Korean so slim, right ? now... i will tell you their secrets for diet, this is Traditional Diet from Korean ^^

Koreans will eat something close to the following for each meal. They always eat veggies. if you like watching Korean drama, movie, reality show, variety show, etc, you'll fine spicy things and vegetables. it because spicy and veggies is good for metabolism.

this is the example for their meal...


Breakfast
Rice, side-dishes made previously the day before (like Spinach side dish, kimchi, radish side dish, perilla leaf kimchi, and young summer radish kimchi), and a soup to accompany the meal. Soups served in the morning are not too spicy, oily, or meat rich. Soups like soybean sprout soup, seaplant soup, bean paste soup, dried pollack soup, or cabbage bean paste soup are good choices.

Lunch
Rice, Kimchi and other side dishes (like fish cake side dish, egg side dish, bean sprout side dish, pan fried tofu, etc) are usually accompanied by a meat/fish entree such as bulgogi jungol. Spicy stews such as soft tofu stew, spicy fish stew, yukgaejang, bean paste soup, or kimchi stew may be accompanied with the meal. Additional food like Vegetable pancakes, squash pancakes may be ordered seperately.
Usually there is no desert, but if there is, it is usually fruit cut into bite size pieces (apple, pear, persimmon, etc.) or a small serving of shikhae or sujungwa. Lunch can also be a simple bowl of noodles like jajangmyun, sujebi, jajangmyun.

Dinner
Usually considered the largest meal of the day, menu is usually the same as lunch. However, noodles are not as popular for dinner. Dinner tends to be a more formal meal to Koreans with more side dishes and varieties of food rather than a simple bowl of noodles.

Most important ingredients you will always need to cook basic Korean food :
Garlic, Kimchi, Red pepper flakes, red pepper paste, sesame oil, dried anchovies, soy sauce, & soy bean paste.

Secondary ingredients: 
Roasted sesame seeds, tofu, fish sauce, green chili peppers, green onions, dried shitake mushrooms, dried kelp, onions, etc.

Fact :
Kimchi is good for diet. i really wanna try it again. i'd ever tried make kimchi... but i did wrong so the taste so horrible. that's why i wanna make it again until i can make the tasty one :D
