Does Co-administration of Lactate to an Oral Glucose Tolerance Test Lower the Glucose Response?
To investigate whether co-administration of lactate with a glucose load affects postprandial glucose levels/handling, gastrointestinal hormones, gastric emptying, and appetite sensations in individuals with pre-diabetes when compared to placebo.

Hypothesis:

Oral lactate administration improves/lowers glucose excursions following an oral glucose tolerance test (OGTT) by stimulating insulin secretion and delaying glucose absorption.
