As with everything it depends on the communities you run with. The core tenet of fat acceptance is that your weight doesn't define your value as a human. Proana which is short for pro-anorexia, also known as thinspo (thin inspiration) has the core tenet of advocating and encouraging an eating disorder as how you'd obtain value. The point of thinspo is to provide people inspiration and motivation to starve themselves, which is otherwise unnatural for humans to do. if you found a community that advocate overeating as the aesthetic ideal that would be as toxic. with the caveat being that being underweight is more dangerous from a health standpoint than overweight is. again, it all depends on the community and exactly what they're advocating for. you'd be more attractive if you were thiner that is healthy, is a lot more toxic of an idea than being fat doesn't mean there's something wrong with you.
