Summary

This study tested whether time-restricted eating (eating only during certain hours of the day) could improve blood vessel health and brain function in older adults at risk for age-related memory decline. Researchers measured changes in brain blood flow and electrical activity in 32 participants aged 55 to 80. The goal was to understand if this eating pattern might help prevent cognitive decline.
