Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

This pilot clinical trial will test the hypotheses that sleep restriction (for 5 nights), in comparison to "normal sleep", will: 1. Decrease peripheral insulin sensitivity and glucose tolerance, as measured by the hyperinsulinemic-euglycemic clamp and oral glucose tolerance test. 2. Decrease hepatic insulin sensitivity, as assessed by stable isotope studies of endogenous glucose production, gluconeogenesis and glycogenolysis.

Site investigator names are published by ClinicalTrials.gov only while a study recruits, so completed studies list sites without them.
