To test a 14-hour prolonged nightly fasting (PNF) protocol in a group of older adults (≥ 65 years old) with self-identified age-related cognitive decline (ARCD) on the primary outcome of neurocognitive function and performance as measured by objective outcomes. The investigators will use an 8-week single group pre-post pilot study design to measure outcomes related to neurocognitive function and performance and cardiometabolic risk factors (i.e., sleep disturbances, body mass index).
