Summary
This study tested whether drinking an extra 1.5 liters of water daily for a year could lower blood sugar in adults with signs of dehydration and high blood glucose. Nearly 800 participants were split into two groups: one received lifestyle advice plus extra water, the other only lifestyle advice. The goal was to see if better hydration could improve metabolism and reduce diabetes risk.
