Americans are the fattest people in the industrialized world, while Koreans are the slimmest. There are many reasons for this, but one huge factor is diet. The Korean will have a post about the healthiness of Korean diet, but the most important point, for the Korean, is this: Koreans eat less. Portion size served in restaurants in Korea is anywhere between half to two-thirds of portion size in America.
Now, American government seems to have taken notice, which is a good news.
