A reward that has contributed to human survival in evolution is destroying us in today's world of abundance. "We are not meant to say no all the time. That's why we usually do not stop eating, even though we're full, "stresses Tittgemeyer. Obviously, the reward signals overshadow satiety - over-saturation and obesity are the consequences.
