How much you eat when you're not really hungry may depend on how well off your family was when you were a child, according to new research. Previous research has established childhood poverty as a risk factor for obesity, but the mechanisms driving this relationship are not completely clear. New research shows that growing up poor promotes eating in the absence of hunger in adulthood, regardless of one’s wealth in adulthood. This biological blueprint would help children survive in impoverished environments, leading them to seek out food whenever it is available, and would continue to drive their behavior as they aged, regardless of whether their access to food had improved.
