ESPResearchers at Northwestern Medicine explored whether timing an overnight fast to match a person's natural sleep wake cycle could improve heart and metabolic health. The circadian rhythm plays a central role in regulating cardiovascular and metabolic function. Importantly, participants did not reduce calories. The focus was entirely on adjusting when they ate.
The study found that middle age and older adults at elevated risk for cardiometabolic disease benefited from extending their overnight fasting window by roughly two hours. They also avoided food and dimmed lights for three hours before going to sleep. These changes led to measurable improvements in heart and metabolic markers during sleep and throughout the following day.
