Purpose of review: Disordered eating behaviors (DEBs) are associated with poor weight outcomes following bariatric surgery. We describe DEBs most relevant to this population, their associations with weight outcomes, and emerging data on interventions for DEBs.
Recent findings: Loss of control eating episodes and grazing have been the most well studied DEBs in bariatric samples. Although DEBs often remit after surgery even without targeted intervention, a subgroup of patients have persistent or newly developed DEBs postoperatively. Preoperative DEBs have little effect on weight outcomes, whereas preoperative impulse control-related features commonly associated with DEBs (e.g., inhibitory control) may have stronger predictive value. Postoperatively, DEBs appear to exert robust effects on concurrently measured weight. Postoperative interventions hold promise for optimizing treatment outcomes.
Summary: We recommend the following to improve clinical care and move research forward: a common language for DEB constructs is needed to improve cross-talk among researchers and care providers; diagnostic schemes and assessment tools may require tailoring for the bariatric population; mechanisms underlying improvements in DEBs following surgery should be clarified; ongoing monitoring of DEBs in the postoperative period is warranted; and a stepped-care approach may improve weight outcomes in a cost-effective manner.
