Social networks and health behavior

In the developing world obesity has become one of the major health challenges. Our diet is a crucial determinant of our weight. But humans are omnivores; they have to choose what they eat. This choice is at least in part determined by peers and the social norms one is exposed to. Several theories try to explain why the presence of others influences our food choice: among them the evolutionary perspective, identity theory, and psychological factors. Drawing on each of these theories this research tries to assess how peer groups and their social composition affect the food choices of an individual.
