That was the case until the Asians began consuming western diets, which are characterized as being processed, high in fat and sugars, and low in fiber and nutrition. This is of course coupled with with other things that the modern age has brought, such as conveniences, which can cause individuals be less physically active. Now the wave has reached the shores of some developing nations.
