Feasibility of Implementing Time-restricted Eating in Women With Mild Cognitive Impairment

This study will investigate the feasibility of implementing a time-restricted eating intervention in females with mild cognitive impairment. Targeted therapeutic interventions that improve cognitive impairment and delay onset of ADRD are particularly important for females, who have twice the lifetime risk of developing AD, compared to males.

This study will investigate the feasibility of implementing a time-restricted eating (TRE) intervention in females with mild cognitive impairment. Data will be collected for 10 weeks. Baseline food timing, activity/sleep, metabolic health (fasting labs and anthropometric measures), and cognitive testing will be collected in the first two weeks. Subjects will then be invited to enroll in a TRE intervention for 8 weeks. Subjects will be educated about the potential health benefits of TRE, and then each subject will self-select a 10-hr window and consume all daily calories during this time frame. Subjects will text the time of their first and last daily calories for the duration of the study. At the end of the 8-week TRE intervention, metabolic, anthropometric, activity/sleep, and cognitive measurements will be collected.

Participants will have baseline and post-study data collected, including activity/sleep data, metabolic parameters (fasting labs and anthropometric measurements), and cognitive testing. In addition, food timing will be collected throughout the study. Subjects will be educated about the potential health benefits of time-restricted eating and will self-select a 10-hr window, during which all daily calories will be consumed for 8 weeks.

Subjects will be educated about the health benefits of time-restricted eating. Each subject will self-select a 10-hour (10hr +/- 1 hr) window aligned with their active phase during which they will consume all daily calories. Subjects will text the time of their first and last daily calories for the duration of the study.

The times of first and last meals will be collected from participants with an SMS texting system. Adherence defined as minimum 10 hour (+/- 1hr) TRE window 5 days per week.
