obese/obesity

these terms along with "morbid obesity" have medical definitions (although they vary somewhat) and, as such, they are not discriminatory. Generally reserve "obese/obesity" for clinical writing. Outside the medical profession, the terms are often used to make prejudiced statements seem more scientific. Virtually no one self-identifies as obese, unless joking. Nigel Rees (A Man About A Dog) lists "obese" as a synonym for "fat": "Originally obese was more precisely used to describe the very fat and fleshy and the excessively corpulent." If describing someone you think is obese, try instead using adjectives as interesting as his. See also fat.
