Have you ever felt "hangry?" The term stems from a new study that found married couples are more likely to argue when they’re hungry.  

Dr. Brad Busham is the lead author of the study and a professor of communication and psychology at Ohio State University. He joined Fox and Friends to explain the science behind being "hangry."

The study measured anger with voodoo dolls and found that spouses were more likely to pin the doll when their blood sugar levels were lower.

“Aggression often starts when self-control stops,” Dr. Bushman said. “Although the brain’s only about two percent of our body weight, it consumes about 20 percent of the calories. So to regulate anger, the brain needs a lot of fuel and we get that fuel from the food we eat.”

His advice? Don’t bring up issues with your spouse on an empty stomach.
