Interventions

  • Early Time-Restricted Eating (eTRE) — BEHAVIORAL
    Participants in the eTRE group will be asked to fast for a target of 16 hours per day (eat ad libitum within the 8-hour eating window, starting between 6:30-9:30 am), 6 days/week for 12 weeks. Participants will be allowed to consume calorie-free beverages, sugar-free gum, and will be encouraged to drink plenty of water throughout the entire intervention period.

Study Details

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.
