Abstract

Objective

This study examined eating behaviors over 12 months in lower, medium, and higher responders to metabolic bariatric surgery (MBS).

Methods

Eating behaviors were assessed using the Three-Factor Eating Questionnaire, Dutch Eating Behaviour Questionnaire, and Binge-Eating Scale in 112 gastric bypass patients before and at 6 and 12 months after surgery. Body weight, body composition, and metabolic parameters were measured. Based on TWL at 12 months, participants were classified as lower (TWL < 20%, n = 26), medium (20% ≤ TWL < 30%, n = 57), and higher (TWL ≥ 30%, n = 29) responders.

Results

Lower responders exhibited the highest internal hunger and lowest cognitive restraint, while higher responders had the highest baseline restraint. At 12 months, higher responders demonstrated the greatest decreases in rigid control and restrained eating. Hunger and disinhibited eating decreased similarly across groups, but emotional and external eating decreased only in medium and higher responders. Binge-eating declined in all groups, least in lower responders.

Conclusions

Successful weight loss after MBS is marked by lower preoperative hunger, higher cognitive restraint, and postoperative improvements in restraint as well as emotional and external eating. Lower responders show greater hunger, lower restraint, and no improvements in emotional or external overeating. These findings define behavioral signatures of surgical success and highlight targeted opportunities for intervention.

低、中、高反应者在代谢减肥手术后的饮食行为

目的：本研究调查了对代谢减肥手术（MBS）反应较低、中等和较高的患者在12个月内的饮食行为。方法采用三因素饮食问卷、荷兰式饮食行为问卷和暴饮暴食量表对112例胃分流术患者术前、术后6个月和12个月的坐位行为进行评估。测量体重、体成分和代谢参数。根据12个月时的TWL，参与者被分为低应答者（TWL和lt； 20%, n = 26）、中应答者（20%≤TWL和lt； 30%, n = 57）和高应答者（TWL≥30%,n = 29）。结果低应答者表现出最高的内在饥饿和最低的认知约束，而高应答者表现出最高的基线约束。在12个月时，高反应者在严格控制和克制饮食方面表现出最大的下降。饥饿感和去抑制性进食在各组中都有相似的减少，但情绪性和外源性进食只在中等和较高反应者中减少。所有小组的暴食行为都有所下降，反应较低的小组表现最差。结论MBS术后成功减肥的特点是术前饥饿感降低，认知约束增强，术后约束、情绪和外部进食改善。低反应者表现出更大的饥饿感，更低的自制力，在情绪或外部暴饮暴食方面没有任何改善。这些发现定义了手术成功的行为特征，并强调了有针对性的干预机会。

期刊介绍： Eating Behaviors is an international peer-reviewed scientific journal publishing human research on the etiology, prevention, and treatment of obesity, binge eating, and eating disorders in adults and children. Studies related to the promotion of healthy eating patterns to treat or prevent medical conditions (e.g., hypertension, diabetes mellitus, cancer) are also acceptable. Two types of manuscripts are encouraged: (1) Descriptive studies establishing functional relationships between eating behaviors and social, cognitive, environmental, attitudinal, emotional or biochemical factors; (2) Clinical outcome research evaluating the efficacy of prevention or treatment protocols.
