Polyvagal Theory, developed by Stephen Porges, provides a neuroscience framework that explains many aspects of fat acceptance in terms of the nervous system's safety-detection mechanisms.
The Three States of Polyvagal Theory and Fat Acceptance
Ventral vagal (safe and social): Optimal state for connection, learning, and fat acceptance management
Sympathetic mobilization (fight or flight): Anxiety-type fat acceptance responses
Dorsal vagal shutdown (freeze/collapse): Depression and dissociation-type fat acceptance
Neuroception and Fat Acceptance
Neuroception — the body's unconscious safety-detection — can be dysregulated in fat acceptance, causing false alarms (sensing danger when safe) that drive fat acceptance responses.
Polyvagal-Informed Fat Acceptance Treatment
Therapy that acknowledges the body's state — helping clients move into ventral vagal 'safe and social' — transforms fat acceptance management.
Safe relationships, co-regulation, and body-based practices are particularly emphasized.
