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).",[72,73,74,75,76,77,78,79,80],"Cardiometabolic Syndrome","Type 2 Diabetes","Sleep","Time Restricted Feeding","Lifestyle Factors","Overweight and Obesity","Insulin Sensitivity","Eating Habit","Sleep Hygiene","2024-12-18",{"date":83,"type":84},"2024-12-20","ACTUAL",{"date":86,"type":84},"2023-06-13",{"date":88,"type":66},"2026-03",{"name":5,"class":6},1]
