Existing time-restricted eating approaches may have limited adherence and sustainability due to fixed fasting windows with prolonged fasting duration before sleep, or they involve self-selected fasting windows without specifying the duration relative to sleep, a critical period for cardiometabolic regulation. We hypothesized that an individualized approach that extended overnight fasting duration by 3 hours in alignment with habitual sleep time (last meal \u22653 hours before sleep) would enhance nighttime autonomic balance, decrease blood pressure and heart rate, increase blood pressure per hour dipping, and glucose regulation compared with a control group maintaining habitual eating patterns.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>METHODS:<\/jats:title>\n                    <jats:p>In this randomized parallel-arm controlled trial, 39 overweight\/obese participants (36\u201375 years) completed either an extended overnight fasting intervention (13\u201316-hour fasting) or a control condition (habitual fast of 11\u201313 hours). Both groups dimmed lights 3 hours before bedtime. The intervention duration was 7.5 weeks.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>RESULTS:<\/jats:title>\n                    <jats:p>Compared with control, extended overnight fasting intervention significantly improved the coprimary outcome of nighttime dipping of diastolic blood pressure, but not the Matsuda Index of insulin sensitivity. extended overnight fasting improved secondary measures of nighttime autonomic function and morning oral glucose tolerance, including lower nighttime heart rate, higher heart rate variability, lower nighttime cortisol, and during the Oral Glucose Tolerance Test, lower glucose level, and higher 30-minute insulinogenic index, indicating improved acute insulin response.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>CONCLUSIONS:<\/jats:title>\n                    <jats:p>Extending overnight fasting duration by 3 hours in alignment with sleep improved cardiometabolic health in middle-aged\/older adults by strengthening coordination between circadian- and sleep-regulated autonomic and metabolic activity.
