Do you have a good source for this?
It's not "stigmatizing" to call something unhealthy which is, at least potentially, controllable. And you cited no information at all about "endocrine disruptors" for the vast majority of obese people.
Just to point out one potentially complicating factor Dr. Robert Lustig's work appears to show that our diets increasingly include processed foods which are strongly associated with health problems including weight gain and metabolic disease. So if you can completely avoid institutional food such as served at company canteens and figure out and stick to a good diet then maybe. Even then it seems like the stigma is just sloppiness that results in perfectly respectable contributions to society not being recognized.
Early on I made a habit out of becoming friends with fat people I met because their exposure to social stigma tended to make them strong as individuals.
If anything it seems like the person who is addicted to something that should be stigmatized is you.
Asking because as a person who has lost a lot of weight (and kept it off) I would like to get them to reconsider their review process.
Various things have lead to me eating/drinking (alcohol) to excess and becoming more overweight than ever.
My long-winded point is that it seems specifically to be my personal actions that have caused my obesity -- poor food choices and lack of exercise. Others from the same background, others at the same workplace, etc., are not obese.
I would hate anyone to start telling me being fat is OK and that I shouldn't bother to do anything about it.
