Fuck it, I'm fat and I know I'm not healthy because of it.
That being said not all fat people are unhealthy. What matters more is exercise and diet, not how much fat you have. It seems like fatness would follow that but not always, as is in some genetic related conditions.
Also people calling non-fat people fat can go to hell. Seriously.
Actually the people who bring it up in the first place. Unlike smoking, I'm not infecting you with my second-hand fatness. My health is actually none of your business, and I don't need your condescending "concern". You're only going to make things worse for me by trying to bring it up.
Not to mention 90% of the time it's just hecklers looking for a cheap laugh rather than anyone actually concerned. And funnily enough, a lot of these hecklers are, themselves, fat.
To me, "Fat Acceptance" doesn't mean "BEING FAT IS A GOOD THING", but rather "Some of us can't help it, others can but need help, and quite frankly, it's none of your business. Also, stop calling body types that don't actually have much in the way of fat, "Fat", it's erroneous.
Also, eating disorders are a thing. Food addiction is a thing. And unlike smoking, food is everywhere, it's actually the center of our culture, right next to pop culture. You can't escape food commercials, food ads, people eating food. At least with smoking they actually banned cigarette ads."
