CM Trial Summary

This trial suggests that when meals and sleep are not timelined correctly, it alters how the body processes information related to food and sleep. This could have an effect on weight regulation.

Who is the study for?
This trial is for adults with obesity (BMI of 25-34.9) who usually sleep at least 7 hours, starting at or before 4 AM, and eat within an hour of waking up. It's open to all races and ethnicities. People can't join if they have sleep disorders, severe insomnia, psychiatric conditions, recent significant weight changes, are pregnant or post-partum within a year, have high alcohol intake or substance abuse history.Check my eligibility
What is being tested?
The study investigates how the timing of meals and sleep affects body weight regulation without changing sleep duration. It aims to provide guidance on meal and sleep scheduling that could benefit shift workers or those experiencing jetlag.See study design
What are the potential side effects?
Since this trial involves non-medical interventions related to meal times and sleeping patterns rather than drugs or medical procedures, typical medication side effects are not expected.

Experimental Treatment
Active Control
Group I: Circadian misalignmentExperimental Treatment1 Intervention
Meals in this condition will be delayed by 4 hours relative to the circadian alignment condition. Food intake during this period will be from 1 PM to 11 PM.
Group II: Circadian alignmentActive Control1 Intervention
Meals in this condition will be aligned to the sleep episode. Food intake during this period will be from 9 AM to 7 PM.
