Common strategies for reducing body weight rely on limiting energy intake and restricting food choices. However, these strategies have often been proven ineffective in achieving long-term and sustainable weight reduction. More recently, mindful eating as an alternative weight management strategy has gained increasing attention, yet systematic reviews on intuitive or mindful eating published so far present contradictory results. We performed a systematic review and meta-analysis on randomized controlled trials on weight loss programs based on mindful or intuitive eating. We analyzed results using meta-regressions. We included a total of 10 studies and found a significant weight loss effect of mindful/intuitive eating strategies compared with nonintervention controls (-0.348 kg, 95% CI: -0.591 to -0.105, P = 0.005). However, there was no difference compared with conventional diet programs (P = 0.99). Reduction of BMI (-0.137 kg/m , 95% CI: -0.365 to 0.091, P = 0.240) or waist circumference (-0.358 cm, 95% CI: -0.916 to 0.200, P = 0.209) were not statistically significant. Mindful/intuitive eating could be a practical approach to weight control. Limitations of this study include the unbalanced sex, origin, place of residence of the participants, and the short duration of interventions. Future research should aim at investigating long-term effects and include a more heterogeneous study population.
常见的减肥策略依赖于限制能量摄入和控制食物选择。然而，这些策略在实现长期和可持续的体重减轻方面往往被证明是无效的。最近，作为一种替代体重管理策略的正念饮食越来越受到关注，但迄今为止发表的关于直觉或正念饮食的系统评价结果存在矛盾。我们对基于正念或直觉饮食的减肥计划进行了系统的回顾和荟萃分析。我们使用荟萃回归分析来分析结果。我们共纳入了 10 项研究，发现与非干预对照组相比，正念/直觉饮食策略有显著的减肥效果（-0.348kg，95%CI：-0.591 至 -0.105，P=0.005）。然而，与传统饮食方案相比，没有差异（P=0.99）。体重指数（BMI）的降低（-0.137kg/m ，95%CI：-0.365 至 0.091，P=0.240）或腰围的减少（-0.358cm，95%CI：-0.916 至 0.200，P=0.209）也没有统计学意义。正念/直觉饮食可能是一种实用的体重控制方法。本研究的局限性包括参与者的性别、来源、居住地不平衡，以及干预时间较短。未来的研究应旨在调查长期效果，并纳入更具异质性的研究人群。
