Both time-restricted eating (TRE) and high-intensity interval training (HIIT) have been shown to improve cardiometabolic health in people who are overweight and at risk of serious disease. Now a randomized, controlled trial has tested whether combining these two approaches is more effective than either of them on their own. The results show that the combination improved the average long-term glycemic control compared to a no-intervention control group and induced 2- fold greater reductions in fat mass and visceral fat area compared with each intervention in isolation.
The trial had four arms: HIT alone, TRE alone, the TRE-HIIT combination, and a control group. A total of 131 women were enrolled, with 32 or 33 in each arm. All of them had overweight or obesity and had risk factors for cardiometabolic diseases like type 2 diabetes and cardiovascular disease. TRE was defined as consuming all daily calories within a 10-hour time window. HIIT was defined as exercise done at 90% of maximum heart rate for 35 minutes, three times per week. The exercise sessions were supervised by the investigators, and the participants were asked to log their first and last calories every day.
