The chapter discusses eating disorders (EDs), including anorexia nervosa (AN) and bulimia nervosa (BN). After an overview of these disorders, their developmental features, and the main risk factors identified in the epidemiological literature, the chapter critically reviews existing evolutionary models and suggests new directions for research. The final section applies the criteria developed earlier in the book to classify the disorders within the fast-slow-defense (FSD) model and identify functionally distinct subtypes. The author proposes to distinguish between a fast spectrum subtype of EDs marked by dysregulated personality traits (high impulsivity, sensation seeking) and a prevalence of bulimic symptoms (F-EDs), and a slow spectrum subtype that comprises both overcontrolled and high-functioning personality profiles (S-EDs).
