Regardless of gender, this is where doctors go if you are obese, because most of the time, it's because you are obese.
Then of the patients that insist the obesity has nothing to do with it, some of them are right but the majority of those skeptics are wrong and just won't do the diet and exercise. It's hard if you try to take every one of those doubts seriously at first only to ultimately confirm the initial diagnosis over and over again in the patients they give a benefit of the doubt to.
Body positivity was a warranted reaction to the drive to be underweight, but obesity is too far the other way. Being a touch 'overweight' while also being reasonably active seems to be the sweet spot health wise, but obesity can produce just all sorts of health issues that people don't want to admit are related.
