Circadian Intervention to Improve Cardiometabolic Health

RecruitingNA

Sponsor: University of Utah

Conditions: Cardiometabolic Syndrome, Type 2 Diabetes, Sleep, Time Restricted Feeding, Lifestyle Factors

Interventions: Circadian Intervention

Countries: United States

The overall goal is to examine the efficacy of a circadian intervention in people with overweight and obesity and habitual short sleep duration (HSSD). Participants will undergo a randomized controlled trial, with circadian intervention and control (healthy lifestyle) groups. The circadian intervention is designed to reduce nighttime light exposure and after-dinner snack food intake. Alternatively, the control group will receive basic health information (e.g., physical activity, goal setting, and nutrition when eating out).
