> I feel horrible about "body positivity" - making you feel good about an objective problem that's incapacitating and killing you is a huge problem.

It’s also a huge problem when people shame you for being fat. Some of it might be their fault but some of it not. Either way, I think it’s better to accept the body for what it is and work towards improving it and that’s what the “positivity” is. Shaming or judging someone is not a solution, it makes things worse. Yeah it can fuel motivation for some, and be quite detrimental to others - either way it’s nobody else’s business.
