What the study is about

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).

Being studied: Circadian Intervention

Conditions: Cardiometabolic Syndrome; Type 2 Diabetes; Sleep; Time Restricted Feeding; Lifestyle Factors; Overweight and Obesity; Insulin Sensitivity; Eating Habit; Sleep Hygiene
