It's important to love your body. You're never going to get a new one (unless you're a Kardashian). You have to either live with it or change it. If you're a little heavier and you don't want to lose weight, I think that's perfectly fine. If you're a little heavier and you are proud of it, I think that's even cooler. That's the angle this guy is coming from with his "Well fed" tattoo. Sure, you don't really need a tattoo to see that, but I'm always one for comedic irony.
He's going to have an interesting mark leftover if he ever does decide to get gastric bypass or hit the treadmill. If he loses enough weight he could just cut out that portion of skin. I'd say that's a pretty good plan, but it'll require people to stop putting food in him.
