'Feeling fat,' the somatic experience of having excess body weight that is not fully explained by true adiposity, correlates with eating pathology in clinical and non-clinical samples. It is unknown whether 'feeling fat' more strongly relates to specific eating disorder symptom dimensions that typically characterize anorexia nervosa, bulimia nervosa, and/or binge eating disorder. Understanding the significance of 'feeling fat's relationship with specific eating disorder symptom dimensions-cognitive restraint, dietary restriction, binge eating, and purging-may suggest its relevance to particular forms of eating pathology and elucidate treatment directions for addressing 'feeling fat'.
