New research from the University of Arizona shows a correlation between financial stress in childhood (as in, concern about whether there would be enough money for necessities) and a tendency to overeat. People from more privileged backgrounds were more likely to eat based on their hunger level, whereas those who grew up with less comfortable socioeconomic backgrounds tended to eat the same amount regardless of their actual energy needs.
