Generally speaking we don’t want people to be overweight. That’s something we do want to societally minimize. People who are overweight shouldn’t be treated badly, but it’s still a national health concern. We should not, meanwhile, socially minimize the population of minorities or women or trans people or gay people.
I’m saying that that is a partial motivation. It’s not the only motivation. There is a lot of stuff which is just unfair. Disgust, perception of laziness, degrees of racism and sexism, and a lot of societal beauty standards. If it was just about public health concern, we wouldn’t be encouraging women to be super skinny, which can be just as unhealthy as being obese. But there is a legitimate public health reason to want to reduce overweight. There is not for these other bigotries.
And part of this is also changing societal perceptions towards a reasonable healthy perspective. Because we right now are not encouraging people to be a healthy weight, we are expecting someone to be unhealthily underweight. Some fat is normal. And we don’t adequately talk about how unhealthy being super underweight is or how unhealthy bodybuilders often are.
When you say food intake, are you including conditions like Prater-Willi syndrome, where it’s so difficult to stop eating that people literally have to lock up their food? It’s much harder to control your food intake when you produce much more ghrelin (the hormone that signals hunger), it doesn’t drop after eating, and an issue in your hypothalamus means you don’t ever register feeling “full”
