The Surprising Link Between Sleep and Body Weight: Understanding the Impact of Sleep on Hunger and Weight Gain

A new study highlights the significant impact of sleep on body weight. Research from the University of Chicago shows that insufficient sleep can increase cravings for sugary and salty foods and disrupt hunger-controlling hormones, leptin and ghrelin. Another study with over 1000 participants found a direct correlation between sleep loss and weight gain, although sleep alone is not a weight loss solution.
