No comment on whether it's pc nonsense, but ask yourself this; are you healthy? Body positivity claims you should love yourself just the way you are. That's fine up to a point, but if the way you are is bad for your health, how can it be healthy self love? If you are just a few ponds overweight or can't control it because it's glandular, that's one thing. But if your doctors are telling you to eat better, you should listen, no matter how good you feel about yourself.
