Early Time-Restricted Eating for Cardiovascular Health

Aligning Clocks: Time-Restricted Eating to Improve Cardiovascular Health in Hypertensive Older Adults Who Skip Breakfast

Source: ClinicalTrials.gov · Last updated 28 Sept 2026

Brief summary (registry, in English)

This study will examine whether eating earlier in the day within a consistent 8-hour eating window can improve heart and blood vessel health in older adults with high blood pressure who often skip breakfast. Participants will be randomly assigned to either follow an early time-restricted eating schedule or continue their usual eating habits for 12 weeks. Researchers will measure blood pressure, blood vessel function, and biological markers related to the body's internal clock and oxidative stress to better understand how meal timing affects cardiovascular health.
