This actually raises a good point. Taubes mentioned this in one of his many presentations.....some women who lived in poverty where actually pretty fat, while their children were very thin. Yet, they were both suffering from malnutrition. They were both eating crap, but I reckon with time the women's body learned to deal with "famine" by storing as much fat as possible. Maybe something similar is happening with some people in North America. They eat excess calories but it's all sh*t. The body needs to hold on to every ounce because it is getting no NUTRITION and is preparing for famine.
