Summary

This study looks at whether eating all meals within an 8-hour window earlier in the day can improve heart health in adults aged 60 and older who have high blood pressure and often skip breakfast. Over 12 weeks, participants will either follow this eating schedule or stick to their usual habits. Researchers will measure changes in blood pressure and blood vessel function to see if meal timing makes a difference.
