About the study

Sleep deprivation is a major problem in military populations. Some major consequences of sleep loss are inability to concentrate, poor work efficiency, and increase in errors during daily tasks. Ketogenic supplementation is speculated to alleviate some sleep deprivation issues via action of ketones. Ketones are small molecules that appear in the blood when following a ketogenic diet or consuming ketone supplements. The goal of this project is to find out if diet and/or ketones can improve sleep deprivation detriments over 5 days of sleep restriction (-50% from habitual sleep).
