What this trial studies

This pilot study aims to assess the feasibility of implementing a time-restricted eating regimen among adults aged 60-80 with mild cognitive impairment (MCI). Participants will follow a 16/8 fasting schedule, where they fast for 16 hours and eat within an 8-hour window, five days a week for three months. The study will evaluate the impact of this dietary intervention on cognitive performance and metabolic health through neuropsychological tests and biomarker assessments. The research will also measure participant recruitment, retention, acceptability, safety, and adherence to the regimen.

Who should consider this trial

Good fit: Ideal candidates are adults aged 60-80 who meet the criteria for mild cognitive impairment and have a body mass index between 18.5 and 40.0.

Not a fit: Patients with diabetes requiring insulin treatment, eating disorders, or contraindications to time-restricted eating may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to dietary strategies that improve cognitive function and metabolic health in individuals with mild cognitive impairment.

How similar studies have performed: While the approach of time-restricted eating is gaining interest, this specific application in mild cognitive impairment is relatively novel and has not been extensively tested in prior studies.
