NCT06645431

Brief Summary

This clinical trial aims to learn if increasing water intake for five days can lower blood glucose in healthy, free-living individuals. The main question it aims to answer is whether increasing water intake will reduce daily blood glucose. Researchers will compare blood glucose when drinking adequate water to when the same individuals drink a low amount of water to see if blood glucose differs with water intake. Participants will be asked to drink a prescribed volume of water over two weeks while wearing a continuous glucose monitor and collecting two urine voids throughout each day.

Outcome Measures

Primary Outcomes (1)

  • Daily blood glucose

    Area under the curve of daily blood glucose

    14 days

Secondary Outcomes (1)

  • Urine specific gravity

    14 days

Study Arms (2)

High water intake

EXPERIMENTAL

For six days, participants will consume the NAM's recommended total water intake of 2.7 liters per day for women and 3.7 liters per day for men

Behavioral: Water Intake

Low water intake

ACTIVE COMPARATOR

For six days, participants will consume 0.7 liters per day for women and 1 liter per day for men.

Behavioral: Water Intake

Interventions

Water IntakeBEHAVIORAL

Previous studies have not observed blood glucose with adequate vs. low water intake in a free-living situation. The use of continuous glucose monitors allows this.
