Meh, I was born with a crappy metabolism. My father has diabetes and is overweight, and on my mom's side, her weight is very unstable, as is every other female of that side of the family. And on by moms side, both my aunt and my grandmother have diabetes. I don't know if that justifies being overweight, but it should. Some things like this aren't your fault. I'm not saying I'm obese. I've found ways to improve my metabolism. WATER helps a lot. So before acting like a completely insensitive moron, realize that it's not always the persons fault. And instead of calling them fat, next time give adice. Saying things like "PUT DOWN THE FORK!" or "GO OUTSIDE MORE, LARDO!" aren't the best way to deal with things.
P.S. I proclaim fat kid hunting season officially open.
