Most people that are as fat as you might think have metabolism issues. I'm overweight and I run two miles everyday, nothing changes. No, I don't eat a stuffton of food afterwards.
Most people that are fat from eating, eat out of comfort. The more you act like an starfish and force respect loss from everyone because of it, the more they eat because it makes them feel comfortable. If anything, this topic is practically trying to make more fat people than bully them into becoming not-fat.
