Abstract

This prospective study tested whether (a) baseline outcome expectations regarding the benefits of a weight-loss diet, (b) 6-month outcome realizations regarding perceived benefits actually experienced, and/or (c) the interaction between them predicted 6-12-month weight regain among overweight/obese women randomized to one of four popular weight-loss diets (N=311). Positive 6-month realizations regarding improvements in physical shape and appearance predicted less 6-12-month weight regain among Atkins diet participants only (n=70), controlling for baseline expectations, the expectations-realization interaction, and initial weight loss. Atkins participants displayed three distinct patterns of regain based on levels of 6-month realizations and initial weight loss. Experimental research should investigate whether improving realizations leads to reduced weight regain in response to this popular diet.

摘要

本前瞻性研究旨在测试以下三种情况是否可以预测超重/肥胖女性在随机分配到四种流行减肥饮食中的一种后 6-12 个月体重反弹:(a)关于减肥饮食益处的基线预期结果,(b)实际经历的感知益处的 6 个月结果,和/或(c)它们之间的相互作用。对于仅参与阿特金斯饮食计划的参与者(n=70),控制基线预期、预期-实现相互作用和初始体重减轻,6 个月时对身体形状和外貌改善的积极认识预测 6-12 个月体重反弹较少。阿特金斯饮食计划的参与者根据 6 个月时的认识和初始体重减轻水平表现出三种不同的恢复模式。应开展实验研究,以探究提高认识是否会导致对这种流行饮食的反应性体重减轻减少。
