Dude, I am skinny and all I want is for anyone who wants it, to have the experience I have. I have biases, surely, but none against the drugs that let people with disordered eating finally experience a normal appetite, to lose the constant food noise. To enjoy eating in a healthy way, get full and forget about it until physically hungry again. I absolutely do not think most fat people are just lacking willpower or whatever - I don't need willpower to eat normally, just need to pay attention to how I feel.
Maybe because I got here from anorexic and food obsessed in the other direction, getting healthy to the point eating did not make me anxious perhaps gives some perspective. Willpower did not avail me, it just harmed my body.
I do know some people who worry about the side effects of GLPs, whether that is disguised judgemental attitude I don't know. And more who think they are just so expensive it's unequally available and bad for that reason. But not many anymore who think it's just lifestyle alone that is an acceptable way to get to a healthy weight, not after seeing people's results on those drugs.
ETA nevermind on that last paragraph - I see there is someone in this very comment thread saying it's just lifestyle.
