Timing Your Meals: How Eating Schedule Impacts Heart Health

New research from Northwestern Medicine highlights the importance of aligning eating with the circadian rhythm for cardiovascular and metabolic health. The study shows that extending the nighttime fasting window by approximately two hours, combined with avoiding food and dimming lights three hours before sleep, can significantly improve heart health. Middle-aged and older adults with an increased risk of cardiometabolic disease showed improvements in blood pressure, heart rate, and blood sugar levels. The timing of fasting appears to be crucial, as synchronization with the sleep-wake cycle enhances coordination between the heart, metabolism, and sleep. Cardiometabolic health is vital for preventing chronic diseases such as type 2 diabetes and cardiovascular disease. The study showed that nighttime blood pressure decreased by 3.5%, while heart rate fell by 5%. Researchers emphasize that adjusting intermittent fasting around the sleep period may be a realistic and accessible intervention for improving health. They plan to expand the trials to larger studies to confirm the findings and improve the protocol.
