Why Do We Crave Glucose? Study Says Our Brains are to Blame

Researchers at the Imperial College London believe that the desire for glucose may be hard-wired in our brains, Reuters reports. A study conducted on rats shows that glucokinase, an enzyme that senses glucose in the liver and pancreas, increases its activity in the hypothalamus, which may have an affect on a person’s appetite. Researchers also discovered that when glucokinase activity was lower, rats tended to consume less glucose, leading them to believe that glucokinase regulation may serve as an effective treatment for obesity.
