Study on Cardiovascular and Metabolic Health Effects of Eating Duration in Adults with Short Sleep

What this Trial Is About

This research aims to understand how eating duration affects cardiovascular and metabolic health in adults who habitually sleep less than 6.5 hours per night. Short sleep duration is linked to increased risks of heart and metabolic problems, but the exact lifestyle factors and biological mechanisms causing high blood pressure and poor blood sugar control in these individuals are not fully known. The study focuses on whether limiting the daily eating window can improve these health risks by correcting circadian misalignment caused by extended eating times. Participants will be randomly assigned to one of two groups for four weeks one group will follow a time restricted eating TRE plan limiting food intake to 8 hours per day, while the other group will continue their usual eating pattern lasting more than 14 hours daily. Both groups will maintain their habitual sleep schedules. The study will assess how these different eating durations impact blood pressure, insulin resistance, and melatonin secretion patterns. During the study, participants will be monitored for changes in 24-hour mean arterial blood pressure and insulin resistance from baseline to four weeks. Additional measures include 24-hour systolic blood pressure and post-meal blood sugar levels. Participants adherence to the eating schedules, sleep patterns, and physical activity will be tracked. The total study duration for each participant is four weeks, during which various health assessments and metabolic tests will be conducted to evaluate the effects of eating duration on cardiovascular and metabolic health.
