Obesity and related metabolic comorbidities have been associated with more than a 4-fold increased risk of incident cognitive impairment, including Alzheimer’s disease and related dementias (ADRD). Dysfunctional metabolic flexibility is increasingly recognized as a critical mechanism linking metabolic risk factors to risk of cognitive impairment, although few studies portable behavioral strategies to enhance metabolic function among individuals at risk for ADRD. The present study will examine the feasibility and acceptability of a 12-week time restricted feeding intervention among individuals with mild cognitive impairment (MCI). Changes in cognitive and metabolic function will also be examined.

肥胖和相关的代谢合并症与增加的风险增加了4倍以上 事件认知障碍，包括阿尔茨海默氏病和相关痴呆症（ADRD）。功能失调 代谢灵活性越来越被认为是将代谢风险因素与风险联系起来的关键机制 认知障碍，尽管很少有研究可移植行为策略来增强代谢功能 有冒险的人。本研究将检查12周时间的可行性和可接受性 轻度认知障碍的个体（MCI）受到限制的喂养干预。认知和 还将检查代谢功能。
