I saw this today and thought it relevant to this discussion. 
Ezra Klein - The Persistence of Obesity
This reminds me of Charles Karelis's "The Persistence of Poverty." The basic argument is that the wealthy misunderstand the mental state of the poor, which leads them to make conceptual errors when creating policies to address poverty, or, in this case, obesity. Think of a bee sting, he advises. If you have a single bee sting, you'll go buy some salve to take away the pain. Now imagine three bee stings, a sprained ankle, a burn, a cut, a crick in your neck, a sore throat, and arthritis. Does the bee sting matter anymore?
It is one thing for a successful, financially comfortable, socially accepted and respected person who has multiple things happening every day that are pleasurable (golf, driving a nice car, nice home, stylish clothing, success at work, interesting social events, kids doing well, planning vacations, etc) to take just one pleasurable aspect of life (overeating) and sacrifice some of that pleasure for the good result of losing weight.
"Now, for people struggling financially and socially, trying to just get through the day and keep their lives together to varying degrees ... their meals are often the only consistently happy and pleasurable events they can count on each day.
