Time-restricted Eating Study (TRES): Impacts on Anthropometric, Cardiometabolic and Cardiovascular Health

Summary

The goal of this clinical trial is to learn about the effects of time-restricted eating in patients with history of acute coronary syndrome. The main questions it aims to answer are: 1) Is 10-hr TRE safe and feasible for patients with ACS; 2)What are the impacts of 10-hr TRE on anthropometric measurements, cardiometabolic health and cardiovascular health compared to ad libitum eating in patients with ACS?. Participants will be asked to limit eating duration to 10 hours daily.
