Changing lifestyle habits to achieve and maintain weight loss can be effective in prevention of Type II diabetes. Ability to resist temptations is considered one of the key factors in behavior change. This study examined how habit strength, motivation, and temptations for an energy-dense diet developed during the maintenance stage of a behavior modification intervention tool.
Participants with prediabetes and overweight/obesity were recruited in the two-phase trial PREVIEW with the aim to achieve ≥ 8% body weight loss over 2 months and maintain weight loss over a subsequent 34-month period. The four-stage intervention (PREVIEW Behavior Modification Intervention Toolbox, or PREMIT) supported participants in weight maintenance. Uni- and multivariate analyses were completed from the beginning of the PREMIT maintenance stage (Week 26 of the PREVIEW trial) with 962 individuals who completed the trial.
Habit strength and ability to resist temptations increased during the early PREMIT adherence stage (Weeks 26 to 52) before plateauing during middle (Weeks 52 to 104) and late (Weeks 104 to 156) PREMIT adherence stages. Higher habit strength for energy-dense diet was significantly associated with larger weight regain ( ≤ .007). No changes in motivation or interactions with PREMIT attendance were observed.
Changing diet habits is a complex, multifactorial process, with participants struggling at least with some aspects of weight maintenance. Habits against consuming energy-dense, sweet, and fatty food appeared effective in protecting against weight regain. The observed effect sizes were small, reflecting the complexity of breaking old habits and forming new ones to support long-term maintenance of weight loss.

改变生活方式习惯以实现和维持体重减轻，可以有效预防 2 型糖尿病。抵抗诱惑的能力被认为是行为改变的关键因素之一。本研究考察了在行为修正干预工具的维持阶段，习惯强度、动机和对高热量饮食的诱惑如何发展。
在两阶段试验 PREVIEW 中招募了患有前驱糖尿病和超重/肥胖的参与者，目的是在 2 个月内实现体重减轻≥8%，并在随后的 34 个月内保持体重减轻。四阶段干预（PREVIEW 行为修正干预工具箱，或 PREMIT）支持参与者维持体重。在 PREVIEW 试验的 PREMIT 维持阶段开始时（第 26 周），对完成试验的 962 名个体进行了单变量和多变量分析。
在 PREMIT 早期坚持阶段（第 26 周到第 52 周），习惯强度和抵抗诱惑的能力增加，然后在中期（第 52 周到第 104 周）和晚期（第 104 周到第 156 周）PREMIT 坚持阶段达到平台期。对高热量饮食的习惯强度越高，体重恢复的幅度越大（≤.007）。没有观察到动机的变化或与 PREMIT 出勤率的相互作用。
改变饮食习惯是一个复杂的多因素过程，参与者在维持体重方面至少在某些方面存在困难。反对摄入高热量、甜食和高脂肪食物的习惯似乎能有效防止体重反弹。观察到的效应大小较小，反映了打破旧习惯和形成新习惯以支持长期维持体重减轻的复杂性。（PsycInfo 数据库记录（c）2022 APA，保留所有权利）。
