It’s quite literally the medical term… i… I am an obese man, I am an obese man mostly of my own doing, their might be some psychological or socioeconomic reasons, but it’s mostly the fact that food is good, exercise sucks, and impulse control. I wasn’t born this way, I wasn’t treated as nonhuman for something beyond my control, and obese is not used for the sole purpose of being derogatory.
Those two words are very, very different. Even if you are obese because of a thyroid, or injury, or whatever, a doctor can, and will call you obese in your medical reports. And if you can’t handle that because you can’t handle that slight uncomfortability, no wonder you are still obese.
I do agree that if you are obese and have unrelated medical issues the doctors will very much say “you need to lose weight”, and call it done. And that is x10 if you are a woman, for some reason. Yeah, these problems may not be so bad if I was not obese, and they may not have existed is I wasn’t (bulging disks my back, in my case etc.), but the truth is, I am fat, I still need my problems fixed, go ahead and do the surgery to trim the disk that is pinching my nerves to fix my back because otherwise I can’t move and I will just get fatter and my back will just get worse. Perpetually.
It is just laziness and they have a blanket scapegoat to use to get out of doing their job if you walk in and are overweight.
