Would you believe just one sleepless night can increase your food cravings the next day?

In a new study from the University of Pennsylvania, researchers found just one sleepless night alters the brain’s response to food the next day, increasing food cravings. Their findings concluded that a person who didn't sleep well the night before would crave more food than normal the next day. 

The Study:

• Studied 40 healthy people
• Ages 21-50
• Followed regular sleep schedule of 6-8 hours of sleep/night
  • Sleep-deprived group ate almost 1,000 more calories than they usually would the next day
  • They also ordered more fatty foods and less carbs

MRI scans of the brain revealed a correlation with new cravings to the brain's salience network. Losing sleep broke this pathway, which is known for decision making and behavioral responses.

Rise in Obesity Connected to Sleep?

This study is significant for people who experience trouble sleeping or even work late night shifts. It also builds upon previous studies about the possible neural connection behind obesity and over-eating. 

Some studies previously have shown pathways in the brain of an obese person are stimulated  when anticipate high-calorie food is anticipated, compared to lean and healthy food.

Key to Sleeping Well

According to the National Sleep Foundation, the average adult needs about 7 to 9 hours of sleep at night in order to function and feel good throughout the day.
