The goal of this review was to provide an update on the literature examining how voluntary, temporary abstention from eating impacts cognitive function.
We evaluated peer-reviewed articles published between August 2013 and January 2021 that assessed adults, included a measure of cognitive functioning with neutral stimuli, and compared individuals in a fasted state to individuals in a fed state (either within- or between-subject designs). Nineteen articles (21 studies) met inclusion criteria. Sample sizes, fasting methods, and tasks varied across studies. Review of studies indicated that fasting was associated with deficits in cognitive functioning; few studies indicated a benefit in cognitive functioning following a single voluntary fast. The heterogeneity and rarity of available studies limits the conclusions that can be drawn. Several crucial psychosocial and sociodemographic moderators remain unexplored. Recommendations for future work are discussed.
本文旨在提供关于自愿性短期禁食对认知功能影响的文献综述更新。
我们评估了 2013 年 8 月至 2021 年 1 月期间发表的同行评议文章，这些文章评估了成年人，包括使用中性刺激的认知功能测量，并将禁食状态下的个体与进食状态下的个体（无论是在个体内还是个体间设计）进行了比较。19 篇文章（21 项研究）符合纳入标准。研究中的样本量、禁食方法和任务各不相同。对研究的回顾表明，禁食与认知功能缺陷有关；很少有研究表明单次自愿禁食后认知功能会有改善。现有研究的异质性和稀缺性限制了可以得出的结论。一些关键的心理社会和社会人口学调节因素仍未得到探索。讨论了对未来工作的建议。
