Really? Is it a US thing?
I'm overweight but not obese, and basically every doctor I've seen for various issues (blood pressure, back pain, sprained ankle) told me to lose weight, in two european countries.
I don't think so. They may be referring to the fact that it is increasingly becoming an issue of political correctness. But science is pretty clear about the risks of obesity and the medical professions follow that.

I have a friend who's (US) doctor told he needs to lose weight or he will die. It got him to join a gym at least.
Obesity is more or less considered to be normal now, it’s a real shift in the last few decades.
With my new doctor, I was looking at my last 2 yrs of blood tests and my LDL cholesterol has been at 105. Losing more weight will help with that, so will changing my diet - but my doctor didn’t point my LDL out as a problem even though it is.
