First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether eating only during a set window each day (time-restricted eating) combined with supervised exercise can reduce fat in the liver and improve heart health in adults with obesity. 187 people took part. The goal was to see if the combination works better than either approach alone.
