"To me this is a better (and more realistic) explanation that just " oh well the poor are obese because they are DENIED good food." Please"

I never get this, either. I mean, what is the real difference between grocery stores in wealthy areas and poor areas? It's really not much - maybe the difference between generic chicken nuggets and Tyson. I think the explanation is more that the very wealthy are more motivated and tied to image and so they keep thin. The middle classes are a little less obese than the poor folks, but not by much. All of the VP's/middle managers at companies I know are obese. The CEO's aren't but the VP's are. There was a study out of England showing that the rate of growth in middle-class areas far outstripped what was happening amongst the poor. It's really more abou blaming a general problem on poor people. I see people who are policymakers who are easily 40 BMI talking about how obesity is such an issue with poor people and how they need help. What the heck?
