Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of this project is to investigate the impact of dinner timing on eating behaviors, physical activity and metabolic healthy in healthy adults

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

In the early dinner trial, participants will be required to eat dinner between 17:30 and 19:00 for a week. In the delayed dinner trial, participants will be required to eat dinner between 20:30 and 22:00 for a week. During the intervention, energy intake (3 days of weekday and 1 day of weekend), physical activity (7 days), glucose concentrations (7 days) and sleep (7 days) will be monitored continuously for both early and delayed dinner.

After intervention, body composition, cognition, food preference, metabolic health and resting metabolic rate will be measured.
