Behaviour change interventions for weight management have found varied effect sizes and frequent weight re-gain after weight loss. There is interest in exploring whether differences in eating behaviour can be used to develop tailored weight management programs. This secondary analysis of an 18-month weight maintenance randomised controlled trial (RCT) aimed to investigate the association between individual variability in weight maintenance success and change in eating behaviour traits (EBT). Data was analysed from the NoHoW trial (Scott et al., 2019), which was designed to measure processes of change after weight loss of ≥5% body weight in the previous year. The sample included 1627 participants (mean age = 44.0 years, SD = 11.9, mean body mass index (BMI) = 29.7 kg/m, SD = 5.4, gender = 68.7% women/31.3% men). Measurements of weight (kg) and 7 EBTs belonging to domains of reflective, reactive, or homeostatic eating were taken at 4 time points up to 18-months. Increases in measures of 'reactive eating' (binge eating, p < .001), decreases in 'reflective eating' (restraint, p < .001) and changes in 'homeostatic eating' (unlimited permission to eat, p < .001 and reliance on hunger and satiety cues, p < .05) were significantly and independently associated with concomitant weight change. Differences in EBT change were observed between participants who lost, maintained, or re-gained weight for all EBTs (p < .001) except for one subscale of intuitive eating (eating for physical reasons, p = .715). Participants who lost weight (n = 322) exhibited lower levels of reactive eating and higher levels of reflective eating than participants who re-gained weight (n = 668). EBT domains can identify individuals who need greater support to progress in weight management interventions. Increasing reflective eating and reducing reactive eating may enhance weight management success.
行为改变干预措施在体重管理方面已经发现了不同的效果大小，并且在减肥后经常出现体重反弹。人们对探索饮食行为的差异是否可以用于开发量身定制的体重管理计划很感兴趣。这项对为期 18 个月的体重维持随机对照试验（RCT）的二次分析旨在研究体重维持成功的个体差异与饮食行为特征（EBT）变化之间的关系。该数据来自 NoHoW 试验（Scott 等人，2019 年），该试验旨在测量前一年体重减轻≥5%的个体在减肥后的变化过程。该样本包括 1627 名参与者（平均年龄 44.0 岁，标准差 11.9，平均体重指数（BMI）29.7kg/m，标准差 5.4，性别 68.7%女性/31.3%男性）。在 18 个月内，共进行了 4 次体重（kg）和 7 项属于反射性、反应性或内稳态饮食领域的 EBT 测量。“反应性饮食”（暴食，p<.001）的增加、“反射性饮食”（抑制，p<.001）的减少以及“内稳态饮食”（无限进食许可和依赖饥饿和饱腹感线索，p<.001 和 p<.05）的变化与体重变化显著相关。所有 EBT（除了一种直觉饮食的子量表（因身体原因而进食，p=.715）外，体重减轻、维持或反弹的参与者之间的 EBT 变化差异显著（p<.001）。与体重反弹的参与者相比，体重减轻的参与者（n=322）表现出较低的反应性饮食水平和较高的反射性饮食水平（n=668）。EBT 领域可以识别需要更多支持才能在体重管理干预中取得进展的个体。增加反射性饮食和减少反应性饮食可能会增强体重管理的成功。
