@tree, well said! I'm asian and I also have a hard time putting on weight. I'm too slim or slender for my taste, but most people I know said they kind of envy the body type that I have because like I said, I just can't seem to put on any weight, even if I tried. What i noticed is I eat tons but instead of gaining bulk proportionately, only my tummy grows! My tummy's so biggie. I used to always complain to my sister. My tummy was so flat before, but now, agh... It's a talking flabby tummy, but the limbs remain slender, much too slender for my appreciation. I guess generally, it only has to do with our genetic makeup.
