I use the word "fat." I use that word because that's what people are: they're fat. They're not bulky; they're not large, chunky, hefty or plump. And they're not big-boned. Dinosaurs were big-boned. These people are not overweight: this term somehow implies there is some correct weight. There is no correct weight. Heavy is also a misleading term. An aircraft carrier is heavy; it's not fat. Only people are fat, and that's what fat people are! They're fat!
