A news report from Ozarks First indicates that lack of sleep can contribute to weight gain over the holiday season.
A lack of sleep negatively impacts two hunger hormones, explains Dr. Lynch. “One is leptin. Leptin tells us that we’re satiated and don’t need to eat.”
The other is ghrelin. A hormone that tells us we’re hungry. “When we have not enough sleep ghrelin levels don’t go down during the night and we’re hungrier during the day time. And those leptin levels aren’t replenished during the night and we don’t get as full as easy. And we have these hunger queues.”
