My guy, being fat is not the same as having a hard to pin down chronic illness.

I say this as a guy who does not remember a day where I wasn’t concerned about my weight, who only recently managed to drop from obese to over weight. You can fix being fat. You can fix fat with diet and exercise. You can’t fix “maybe lupus? Maybe MCTD? I dunno it’s probably autoimmune? We’re going to need to order more tests” with diet, exercise, magic crystals, or whatever other random bullshit people like to suggest.
