Dehydration, glucose tolerance, and insulin resistance are related. Many older adults do not achieve the Dietary Reference Intake (DRI) for water, and aging and dehydration are both associated with decreased glucose tolerance. Conversely, weight loss is associated with improvements in glucose tolerance. For older adults following a hypocaloric diet, additional water consumption may lead to greater weight loss.

Our purpose was to investigate the possibility that increased water consumption among older adults (n=29, BMI=31+1 kg/m2, age=62+1 years) could improve glycemia beyond that observed with weight loss, as well as associations between plasma copeptin and diabetes risk. Analysis of diabetes-related variables for subjects grouped according to study intervention group, amount of drinking water consumed, or pair-matched for weight loss and gender did not reveal significant differences between groups.
