Cravings for fatty foods, sweets, and overeating: A study just published in Scientific Reports reveals why sleep deprivation turns us into junk food addicts. The culprit? A glitch in the brain.
To draw this conclusion, researchers tracked brain activity in 46 men—who are more prone to late-night munchies than women—over 5 days and 4 nights. Twelve slept a full 8 hours nightly. The other 34 got just one full night, followed by 3 nights of sleep deprivation.
Key finding: Sleep-deprived participants downed more than 1,000 extra calories, irresistibly drawn to high-fat foods. Why? Lack of sleep disrupts satiety signals, ramping up pleasure-linked senses like sight, smell, and taste. We end up confusing real hunger with an urge for feel-good treats, like a thick slice of chocolate cake.
Case closed. Here's hoping this science doesn't become an excuse for those midnight snacks!
