RECRUITINGINTERVENTIONAL

Time Restricted Eating and Cardiac Rehabilitation

About This Trial

This study will use a form of intermittent fasting called time-restricted eating (TRE) where individuals consume ad libitum energy intake within a set window of time, commonly 8 hours, which induces a fasting window of 16 hours per day (i.e., 16:8 TRE). TRE could be an effective addition to cardiac rehabilitation as it has demonstrated cardiovascular health benefits and potential for synergy when combined with exercise training. This study will determine if TRE is a feasible and safe nutrition intervention during cardiac rehabilitation and if TRE improves the health benefits of cardiac rehabilitation compared to cardiac rehabilitation alone.
