Turns out, counting a bunch of sheep may leave you hungry. Research suggests a lack of sleep can increase hunger.
How Hunger Works
Grehlin, a hormone secreted in your stomach, tells your brain that your body is ready to eat. Once you fuel up, a different hormone named leptin gets released, signals to the brain you’re satiated. Together, these hormones keep your appetite in check. (1)
Sleeping less than five hours can bolster the amount of grehlin released, which causes hunger to increase. Additionally, a lack of sleep cam also decrease leptin levels, so the body doesn’t feel full as quickly. (1)
Proof’s in the Pudding
One study compared groups of well rested and sleep deprived participants, and found those with little sleep (four hours or less) ate a higher number of calories and tended more toward high-fat, high protein foods. (2)
“High-fat food is tempting, and maybe on short sleep you can’t restrain yourself as well, while on full sleep you can resist more easily.”
– Marie-Pierre St. Onge, Ph.D.
Having a large meal close to bedtime can make it more difficult to fall asleep because some foods contain stimulating proteins. (3) It is recommended you eat a light, healthy snack or meal 2 – 3 hours before you hit the sack. (4)
Sleeping keeps you healthy and active. (5) It’s important to keep up with your CPAP therapy, as a good night’s sleep can keep your appetite normalized.
