Official title
Effects of Dinner Timing on Eating Behaviour, Physical Activity and Metabolic Health
Overview
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
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.
