Definition & Terminology
Formal Definition
Etymology & Origins
The term "binge" has been used since the 17th century to describe excessive indulgence, particularly in drinking. The application to eating behavior emerged in the mid-20th century as clinicians recognized the pattern of compulsive overeating as a distinct clinical entity.
Anatomy & Body Systems
Neurobiological Factors
Binge eating involves dysfunction in brain reward and impulse control systems:
Reward System Dysregulation: The mesolimbic dopamine system, involved in reward and motivation, may be dysregulated in binge eating. Individuals may experience altered responses to food cues and reduced sensitivity to natural rewards.
Impulse Control: The prefrontal cortex, responsible for decision-making and impulse control, may show reduced activity, making it difficult to resist eating.
Stress Response: The hypothalamic-pituitary-adrenal axis and stress hormones may be dysregulated, contributing to emotional eating.
Metabolic Effects
- Weight gain and obesity
- Metabolic syndrome
- Type 2 diabetes

Causes & Root Factors
Primary Causes
Genetic Factors: Family and twin studies suggest heritability of 40-60%. Genes related to reward processing and impulse control may be involved.
