Interventions

BEHAVIORAL

Prolonged Nightly Fasting

Participants will engage in 14+ hours a night of fasting and no calorie containing food or beverages for 8 weeks. Participants will be allotted one "cheat day" per week, during which they will not need to fast (or track their times)- the day may change weekly and will be based on participant preference. Study staff and study participants will engage in a weekly coaching call (via phone; 5-10 minutes). Weekly coaching calls will last through the duration of the 8-week intervention.

BEHAVIORAL

Health Education Control

Participants in this group will receive weekly 15-minute videos (once weekly) focused on non-diet/non-fasting health educational content for 8 weeks. Participants will be asked to review the video at their convenience, prior to their weekly coaching call (5-10 minutes) with the study staff. Weekly topics will be as follows: Week 1: Sleep hygiene, Week 2: Sun safety, Week 3: Home safety, Week 4: Driving safety, Week 5: Hydration, Week 6: Dental health, Week 7: Working environment, Week 8: Communication.
