Summary

This study tests whether eating only between about 6:30 am and 2:30 pm (an 8-hour window) for 6 days a week can improve blood pressure, blood sugar, and heart rate in adults aged 60 and older with high blood pressure. Participants will follow this pattern for 12 weeks. The goal is to see if this eating schedule helps regulate the body's daily rhythms and reduces heart disease risk.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
early time-restricted eating (behavioral intervention)
What this could lead to
If it works, this could offer a simple, drug-free way to help older adults with high blood pressure improve their heart health and daily body rhythms.
What could go wrong
This is a small, early-stage study with only 30 participants, so results may not apply to everyone. The fasting schedule may be hard to stick with long-term, and any benefits might be modest.
