Cost-based anorexia: A novel framework to model anorexia nervosa.

Area of Science:

• Neuroscience
• Behavioral Economics
• Psychiatry

Background:

• Anorexia nervosa (AN) is a complex eating disorder with biological and sociocultural origins.
• Studying human AN etiology is challenging due to practical and ethical limitations.
• Animal models are crucial for understanding AN's neurobiology and behavior.

Purpose of the Study:

• To introduce and discuss the merits of cost-based anorexia (CBA) as an alternative animal model for AN research.
• To highlight CBA's foundation in behavioral economics for studying feeding behaviors.
• To emphasize CBA's potential to incorporate contextual feeding aspects often missed in other models.

Main Methods:

• Conceptual discussion of cost-based anorexia (CBA).
• Exploration of CBA's grounding in behavioral economics principles.
• Analysis of factors influencing CBA magnitude, including feeding context.

Main Results:

• Cost-based anorexia (CBA) is proposed as a valuable addition to AN research models.
• CBA's framework allows for the integration of feeding context, a key element in AN.
• The model's magnitude is adaptable, reflecting real-world feeding complexities.

Conclusions:

• Cost-based anorexia (CBA) presents a promising avenue for advancing AN research.
• This model can bridge the gap between biological predispositions and sociocultural contexts in AN.
• CBA facilitates a more nuanced understanding of eating disorder neurobiology and behavior.
