Time Restricted Eating in Alzheimer's Disease

Participants will be instructed to follow a 16/8 regimen characterized by 16 hours of fasting and an 8-hour eating window daily, on approximately 5 days/week, for 3 months. Previous research has shown that 16 hours of fasting is feasible, safe and well-tolerated among older adults, and that most persons report easy adjustment (Anton, Lee et al. 2019, Lee, Sypniewski et al. 2020). The intervention will be implemented through individual and group sessions with participants and will involve extensive education, coaching, guidance, and support throughout the 3-month intervention. Educational materials on lifestyle factors including physical activity will be provided to each participant. We will be also be collecting data on physical activity and sedentary behavior. These data will be co-variates when we conduct the statistical analysis.
