Conner: Wait - is there actually any real science behind being hangry? Julia: There totally is! The human brain uses more energy than any other organ in the body. Despite being only 2 percent of our total body weight, the brain needs over 20 percent of all the calories we eat! And it burns those calories as energy in the prefrontal cortex, which is the part responsible for self control and personality expression. So when we’re not fueling our gluttonous think tanks, we’re actually losing self-control. That’s when hangry gets real - real fast.*** You see, when self control stops, aggression often starts. Studies of people who had low levels of glucose, or empty stomachs, were more likely to act aggressively to loved ones, be rude to strangers, even damage someone’s hearing. Seriously! One study from Ohio State University gave one group of students lemonade sweetened with sugar, and the other got lemonade sweetened with Splenda. Sugar has calories, which provide fuel for the brain. Splenda does not. So what was the hangry group more likely to do? Blast a complete stranger with a loud noise through headphones. Why? Cause I’m so damn HANGRY!!! Thanks for watching guys!
