DT2 Trial Summary

This trial looks at the effects of eating dinner at different times, based on an individual's natural sleep cycle. Blood samples will be taken to measure how well the body processes different nutrients.

Who is the study for?
This trial is for healthy adults aged 18-30, with a BMI of 18-30 kg/m2 and normal sleep patterns (bedtime before 1:00 A.M. and mid-sleep before 5 A.M.). Participants should not be smokers or have conditions like diabetes, sleep disorders, GERD that affects eating near bedtime, or use medications affecting circadian rhythms.Check my eligibility
What is being tested?
The study investigates how the timing of dinner relative to one's own circadian rhythm impacts metabolism. It involves having an early or late dinner based on melatonin onset measurements and observing changes in metabolic markers like glucose and insulin levels.See study design
What are the potential side effects?
Since this trial involves only meal timing adjustments without any drugs or medical interventions, there are no direct side effects expected from participating in the study itself.

DT2 Trial Design

3Treatment groups
Experimental Treatment
Group I: Late Dinner firstExperimental Treatment3 Interventions
Participants will be served dinner and a stable isotope of palmitate to measure fat oxidation, at a late dinner time (DLMO+1h) followed by a sleep study (DLMO+2h). This arm will cross-over to the other 2 arms in random order.
Group II: Late Dinner + Late Sleep firstExperimental Treatment3 Interventions
Participants will be served dinner and a stable isotope of palmitate to measure fat oxidation, at a late dinner time (DLMO+1h) followed by delayed bedtime (DLMO+6h). This arm will cross-over to the other 2 arms in random order.
Group III: Early Dinner firstExperimental Treatment3 Interventions
Participants will be served dinner and a stable isotope of palmitate to measure fat oxidation, at an early dinner time (DLMO-3h) followed by a sleep study (DLMO+2h). This arm will cross-over to the other 2 arms in random order.
