Actually, for a lot of those people, "living" and "eating" seem to have similar meanings. Even though I'm on a 3,000kcal diet, some of them feel the urge to tell me that I should "enjoy life" or "celebrate my youth", and they never seem to have an answer when I tell them that I love enjoying life: I love lifting, stretching, running, hiking, cycling, teaching, studying, working, partying... why do they associate joy with food? And the worst part is that they are never enjoying actual taste. They are always complaining there's not enough salt, or not enough sugar. I've never seen a fattie eating McBeetus and saying "I can't even taste the meat properly, it's too overloaded", or one of them drinking Starbeetus and saying "this doesn't even taste like coffee, it's too sweet".
