Study: people who grow up poor have a harder time regulating their food intake
A bit missing from these studies are my parents' generation. My father grew up in hard times during the Depression, my mother grew up in WW2 ravaged Europe and spent some years with severe food shortages. Neither had any sort of obsessive relationship with food.Ok, 2 people is not data. But this happened to tens of millions of people. As I understand it, that generation was less obese than later generations.
