Food Addiction and Bariatric Surgery: A Systematic Review of the Literature
Open accessAbstract
Emerging research suggests that rates of food addiction are high among individuals seeking bariatric surgery, but little is known about associated features and the prognostic significance of pre-operative food addiction. Thus, this article provides a systematic review and synthesis of the literature on food addiction and bariatric surgery. Articles were identified through PubMed and SCOPUS databases, resulting in a total of 19 studies which assessed food addiction among pre-bariatric and/or post-bariatric surgery patients using the Yale Food Addiction Scale. Most studies were cross-sectional, and only two studies prospectively measured food addiction both pre-operatively and post-operatively. The presence of pre-surgical food addiction was not associated with pre-surgical weight or post-surgical weight outcomes, yet pre-surgical food addiction was related to broad levels of psychopathology. The relationship between food addiction and substance misuse among individuals undergoing bariatric surgery is mixed. In addition, very few studies have attempted to validate the construct of food addiction among bariatric surgery patients. Results should be interpreted with caution due to the methodological limitations and small sample sizes reported in most studies. Future rigorous research with larger and more diverse samples should prospectively examine the clinical utility and validity of the food addiction construct following bariatric surgery.

Weight regain after bariatric surgery is associated with problematic eating behaviors that have either recurred after a period of improvement or are new-onset behaviors.
“Weight regain after bariatric surgery is associated with problematic eating behaviors that have either recurred after a period of improvement or are new-onset behaviors.”
From Behavioral Interventions to Attenuate Driven Overeating and Weight Regain After Bariatric Surgery (2022) · cites this paper as [7]
The Discussion (page unavailable) reports that postoperative loss-of-control eating and binge-eating disorder are associated with poorer weight outcomes. It does not establish that weight regain is associated specifically with eating behaviors that recur after improvement or begin after surgery; it says the emergence or re-emergence of postoperative food addiction has not been prospectively examined in relation to poorer long-term weight outcomes.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
