Study Summary
This study examines the acute impact of eating an "early" versus "late" dinner. "Early" and "late" will be customized to individuals based on the individuals' own circadian rhythms. Healthy adults will have the adults' circadian rhythm assessed by measuring the adults' dim light melatonin onset (DLMO). Based on the timing of DLMO, participants will be randomized to eating dinner before DLMO or after DLMO. The investigators will also compare the effects of delaying sleep relative to dinner time. Participants will eat meals in the laboratory and have serial plasma samples collected to examine profiles of free fatty acids, glucose, insulin, triglycerides, and oxidation of dietary fat.
Primary Outcome
Serial blood samples taken during visit, 25 samples taken over 25 hours (One every hour) per visit.
Interventions
- BEHAVIORAL Late Dinner
- BEHAVIORAL Early dinner
- BEHAVIORAL Late Dinner + Late Sleep
