Area of Science:

  • Behavioral Science
  • Psychology
  • Nutrition Science

Background:

  • Conventional models of eating and overeating focus on physiological drives like hunger and satiety.
  • These models may not fully capture the complexities of everyday food intake and overconsumption.

Purpose of the Study:

  • To challenge the primacy of hunger and satiety in explaining eating behavior.
  • To propose a normative control framework for understanding food intake and overeating.

Main Methods:

  • Conceptual analysis and theoretical argument.
  • Examination of personal and situational norms influencing food intake.

Main Results:

  • Hunger and satiety play a minor role in typical eating occasions.
  • Food intake is largely governed by the motive to avoid excessive consumption.
  • Personal and situational norms significantly influence eating behavior.

Conclusions:

  • A normative approach provides a more comprehensive understanding of eating and overeating.
  • Interventions targeting eating behavior should consider normative influences.
