Then to make matters worse, in the US hospitals and doctors can be punished for trying to help obese, especially very obese patients. The ACA brought along patient satisfaction scores. So if you don't like what your being told you can score the hospital/doctor lower. While the economic impact might be measured in small percentages the tightness is costs makes this a big factor. You can guarantee this affects how the obese and very obese are treated, in many cases they will be coddled and never once will their weight be mentioned.
Finally we have far too many people inactive in this country and many others because government benefits programs are sufficient to allow them this lifestyle. Simply put, if you keep paying and feeding people not to work just what do you expect them to do? Idleness is not a good state, its worse when we institutionalize it.
Anecdotal but I am sure many have the same experience, there are two groups of co workers who are out the most, very obese people and smokers. Why should either be acceptable? If we can stamp out smoking we can stamp out obesity.
