Differences between successful long-term weight loss maintainers and the general population with regard to eating and weighing habits, non-normative eating behaviors, and eating-related and general psychopathological parameters are unknown.
Self-identified weight loss maintainers from the German Weight Control Registry (GWCR, n = 494) were compared with a representative sample of the general German population (n = 2,129). The samples did not differ in current BMI. Using the same assessment instruments in both cohorts, a variety of eating-related and psychological variables were determined.
The GWCR participants reported more self-weighing and higher eating frequency but less hot meal consumption and more eating-out-of-home. Binge eating, compensatory behaviors, and concerns about shape and weight were reported more often by successful weight loss maintainers. Scores of depression and worrying about health were slightly higher whereas severity of somatic symptoms was less pronounced in the GWCR participants.
Overall, our data suggest that successful weight loss maintainers are characterized by more concerns about shape and weight, greater binge eating frequency, and higher use of compensatory behaviors. The latter suggests that weight loss maintenance might not only be achieved by healthy strategies but also by non-normative behaviors which might increase the vulnerability for weight regain.
成功长期保持体重减轻的个体与一般人群在饮食和称重习惯、非规范饮食行为以及与饮食相关和一般心理病理参数方面的差异尚不清楚。
本研究将德国体重控制登记处（GWCR）中的自报体重减轻维持者（n=494）与具有代表性的一般德国人群（n=2129）进行了比较。两个队列在当前 BMI 方面没有差异。在两个队列中使用相同的评估工具，确定了各种与饮食相关和心理变量。
GWCR 参与者报告了更多的自我称重和更高的饮食频率，但较少食用热餐和更多外出就餐。成功的体重减轻维持者更频繁地报告暴食、补偿行为以及对体型和体重的担忧。GWCR 参与者的抑郁和对健康的担忧评分略高，而躯体症状的严重程度则较低。
总体而言，我们的数据表明，成功的体重减轻维持者更关注体型和体重，暴食频率更高，并且更频繁地使用补偿行为。后一种情况表明，体重减轻维持不仅可以通过健康的策略来实现，也可以通过非规范的行为来实现，这可能会增加体重反弹的脆弱性。
