. . .or what people say when you are hungry, and become grumpy!

A lot of people get tired and cranky when they don’t eat, and snap at other people, etc. This state of mind is known in the fitness and exercise world as “hangry.” But why do we become like this when we don’t eat for long periods of time?

The physiology of Hangry come from scientific knowledge. Amanda Salis who is a NHMRC Senior Research Fellow in the Boden Insitute of Obesity, Nutrition, Exercise & Eating Disorders at University of Sydney writes: “The carbohydrates, proteins and fats in everything you eat are digested into simple sugars (such as glucose), amino acids and free fatty acids. These nutrients pass into your bloodstream from where they are distributed to your organs and tissues and used for energy. As time passes after your last meal, the amount of these nutrients circulating in your bloodstream starts to drop. If your blood-glucose levels fall far enough, your brain will perceive it as a life-threatening situation. You see, unlike most other organs and tissues in your body which can use a variety of nutrients to keep functioning, your brain is critically dependent on glucose to do its job.”

You’ve probably already noticed this dependence your brain has on glucose; simple things can become difficult when you’re hungry and your blood glucose levels drop. You may find it hard to concentrate, for instance, or you may make silly mistakes. Or you might have noticed that your words become muddled or slurred.”

With this in mind, it is very important to stay on top of eating every three hours and not starving yourself for a long period of time. It can cause more damage than just trying to lose weight. Eating helps.
