Food Addiction in Sleeve Gastrectomy Patients with Loss-of-Control Eating.

OBJECTIVE

Food addiction and binge eating share overlapping and non-overlapping features; the presence of both may represent a more severe obesity subgroup among treatment-seeking samples. Loss-of-control (LOC) eating, a key marker of binge eating, is one of the few consistent predictors of suboptimal weight outcomes post-bariatric surgery. This study examined whether co-occurring LOC eating and food addiction represent a more severe variant post-bariatric surgery.

METHODS

One hundred thirty-one adults sought treatment for weight/eating concerns approximately 6 months post-sleeve gastrectomy surgery. The Eating Disorder Examination-Bariatric Surgery Version assessed LOC eating, picking/nibbling, and eating disorder psychopathology. Participants completed the Yale Food Addiction Scale (YFAS), the Beck Depression Inventory-Second Edition (BDI-II), and the Short-Form Health Survey-36 (SF-36).

RESULTS

17.6% met food addiction criteria on the YFAS. Compared to those without food addiction, the LOC group with food addiction reported significantly greater eating disorder and depression scores, more frequent nibbling/picking and LOC eating, and lower SF-36 functioning.

CONCLUSION

Nearly 18% of post-operative patients with LOC eating met food addiction criteria on the YFAS. Co-occurrence of LOC and food addiction following sleeve gastrectomy signals a more severe subgroup with elevated eating disorder psychopathology, problematic eating behaviors, greater depressive symptoms, and diminished functioning. Future research should examine whether this combination impacts long-term bariatric surgery outcomes.
