About this study
This pilot and feasibility study will enable the research team to determine the feasibility of implementing a time-restricted eating regimen among adults with mild cognitive impairment (MCI) and the impact of time-restricted eating on cognitive performance and biomarkers of metabolic health in this population. Study staff will execute the specific aims using a pre-post, non-randomized study design in which all participants receive the intervention. The intervention is a 16/8 time-restricted eating regimen characterized by fasting for 16 hours and eating within an 8-hour window on 5 days per week for 3 months. Assessments will be performed at baseline and after the 3-month time-restricted eating intervention with the following outcome measures. Outcome measures for feasibility include participant recruitment, retention and metrics of acceptability, safety, and adherence to the intervention. Outcome measures for cognitive performance and metabolic health include neuropsychological tests, blood biomarkers, and surveys of psychological well-being.
