About this study

This trial is testing if a circadian intervention can improve cardiometabolic health in adults with overweight and obesity, short sleep duration, or both. Participants will be randomly assigned to either receive a circadian intervention (reducing nighttime light exposure and after-dinner snack intake) or basic health information about physical activity, goal setting, and nutrition when eating out. It lasts 1022 days.

Based on ClinicalTrials.gov records.
