Time-restricted eating (TRE) is a type of fasting that involves eating within a specific time window. A recent study found that combining TRE with standard nutritional counseling can lead to improvements in glucose control and weight loss among adults with metabolic syndrome. Participants who engaged in TRE experienced greater reductions in fat mass and hemoglobin A1C (HbA1c) levels compared to those who only followed standard dietary guidance. The study involved 108 participants tracked through the myCircadianClock (mCC) app, with results showing enhanced glucose control and reductions in fat mass for the TRE group.
TRE, often associated with intermittent fasting, has gained popularity as a weight management method. This approach typically includes consuming food within an 8 to 12-hour window each day and fasting outside of that period. Previous research suggests TRE may offer benefits such as weight loss, improved cholesterol levels, better insulin sensitivity, and other health benefits. The study randomized participants into two groups, with one receiving standard nutritional advice and the other instructed to follow a personalized 8 to 10-hour eating window alongside the same guidance.
Over a three-month period, researchers monitored the intervention remotely and tracked participants’ meal times using the mCC app. Main outcomes focused on changes in fasting blood sugar and HbA1c levels, showing that the TRE group experienced greater reductions in weight with a significant portion from fat loss. Additionally, improvements in blood sugar control and HbA1c levels were more pronounced in the TRE group compared to the standard dietary guidance group. The findings suggest that TRE could be an effective lifestyle intervention for improving glycemic control and metabolic health.
Dr. Emily N C Manoogian, a postdoctoral researcher at the Salk Institute for Biological Studies and lead author of the study, highlighted the benefits of TRE for adults with metabolic syndrome. The research demonstrated that TRE, even when combined with medications like Metformin and Statins, provided positive impacts on multiple aspects of metabolic syndrome, including blood sugar, cholesterol, and body composition. Dr. Mir B Ali, a board-certified bariatric surgeon, noted that intermittent fasting and time-restricted eating have shown benefits for weight loss and fat burning, directing the body towards utilizing stored fat for energy.
The study contributes to the growing body of research supporting the use of TRE for improving cardiometabolic health and glucose regulation. While additional studies with longer durations and larger participant numbers are needed for a comprehensive understanding of TRE’s health impacts, the innovative use of the mCC app for remote monitoring opens avenues for future research at a larger scale. By combining TRE with standard nutritional counseling, individuals with metabolic syndrome may see modest improvements in weight loss, glucose control, and overall metabolic health.
