Sleep Deprivation May Affect Fat Metabolism
Chronic sleep deprivation may increase the risk of heart disease, high blood pressure, stroke, and diabetes. Now a recent study has found that sleep deprivation may also make you feel less full after eating and change the way the body metabolizes fat.
Participants in the study included 15 healthy men in their 20’s who participated in a 10-day sleep study. For 5 of those nights they spent no more than 5 hours in bed each night. They consumed a high-fat dinner after four nights of sleep restriction, and then again after spending 10 hours in bed. The researchers collected blood samples at baseline, after 4 nights of sleep restriction, and after a full night’s sleep.
The participants reported feeling less full after eating the same meal when sleep deprived compared to when they were well rested. When the researchers analyzed the blood samples, they found that sleep restriction resulted in a faster clearance of lipids from the blood. This means the lipids were being stored by the body, which could lead to weight gain.
The study was conducted by researchers from the University of Washington School of Medicine and the Pennsylvania State University. It was published online ahead of print on September 4, 2019 in the Journal of Lipid Research.
