Going back a few years I read a few studies re economic status vs weight, low income = overwieght. Also, women used to smoke to avoid weight gain.
Of course both of these are politically incorrect. Smoking isn't healthy but over eating, obesity, knee replacements and a disability checks because you are too fat to work is good for the economy and hasn't the stigma of smoking.
I'm more concerned about second hand fat. Second hand fat is the obese person blocking the fire exit, falling down in an airplane aisle, plugging toilets, herniated discs trying to get them in an ambulance, that sort of thing.
