Okay you're still saying someone can't be overweight and healthy, so like I promised, I'm gonna assert that there's no such thing as men's health. Being male will make a man die sooner. We need to give all men estrogen pills immediately and make sure they stick to the regimen. Being male is not okay, it's bad for you and it's driving up insurance costs for the rest of us. It's selfish. Making bad choices out of stubbornness and pride while everyone else pays. That's not okay.
Please note these are not my actual views, I'm just applying anti-HAES logic to other parts of our bodies in the same manner.
Men and women tend to be different sizes, as I'm sure you've noticed. Body size and shape is part of gender. Trans people who are too big or too small to fit their ideal body shape suffer dysphoria. And in cis people, the symptoms of obesity bear an eerie similarity to stress symptoms. Part of the unhealth of obesity for many cis people is gender dysphoria. They have a body shape that doesn't make them happy, it stresses them out. However, not everyone in the world is a man or a woman. There are other genders, and some of those genders have an ideal size that is larger.
You say gender is nothing to cure, but then you say obesity is always a problem. And you say it to the face of an enby who gained weight on purpose and saw a reduction in physical dysphoria as a result. I didn't feel comfortable taking pictures of myself until I was what the BMI scale calls overweight. When I was thin, the face in the mirror didn't look like mine. It looked like some ugly person I'd been told my whole life was me. I've grown happier and more confident, and I have fewer suicidal ideations
And I still pursue physical health at my current weight.
