I'd deny most healthcare to anyone overweight until they met the (extremely generous) normal numbers on the bmi chart. And I'd deny all healthcare to anyone who was obese. Why should doctors and other health care providers work harder than they do to ensure their health and comfort?    It would be hilarious to see them turned away at ER when they broke an ankle.  Let them suffer the consequences of their poor choices. The rest of us shouldn't be paying for their gluttony.
