Brief Summary:
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).

Official Title: Prolonged Nightly Fasting (PNF) in Older Adults With Age-related Cognitive Decline: A Pilot Study Exploring Changes in Neurocognitive Function (Public Name:Think FAST)
Actual Study Start Date : February 1, 2021
Estimated Primary Completion Date : December 2021
Estimated Study Completion Date : December 2021

Arm Intervention/treatment
Experimental: Intervention Arm
8 week 14 hour prolonged nightly fasting intervention.
Other: PNF
PNF Participants will engage in 8 weeks of 14 hours per night fasting

Primary Outcome Measures :
  1. Memory and Attention Phone Screener (MAPS) [ Time Frame: 8 weeks ]
    Cognitive Function and Performance Test.

Secondary Outcome Measures :
  1. Rapid Eating Assessment for Participants Scale (REAPS) [ Time Frame: 8 weeks ]
    Scale to asses eating behaviors. The scale has a minimum of 13 and a maximum of 39. Higher scores indicate higher diet quality.

  2. Insomnia Severity Index (ISI) [ Time Frame: 8 weeks ]
    Scale to asses insomnia symptoms. The scale has a minimum of zero and maximum of 28 where zero would be absence of insomnia and 28 would be severe insomnia.

  3. Mindful Eating Scale (MES) [ Time Frame: 8 weeks ]
    Scale to asses behaviors related to mindful eating. Each item has a minimum of zero and a maximum of 4 where 4 means less eating awareness.

  4. Creature of Habit Scale (COHS) [ Time Frame: 8 weeks ]
    Scale to asses routine habits. Each item has a minimum of zero and a maximum of 4 where 4 means a more habitual nature.

  5. Salivary Cortisol [ Time Frame: 8 weeks ]
    Measure of cortisol via participant saliva samples.

  6. Body Mass Index (BMI) [ Time Frame: 8 weeks ]
    Self-reported body measurements .
