Have you noticed that you are very nervous and angry when you’re hungry? If so, then you have experienced the phenomenon that is common to a large number of people.
Surely you’ve ever found yourself in a situation that you were very nervous and angry, or simply with no some special reason to start yelling at someone when you had the “attack” of hunger. There are people who, whenever feel hungry, become grumpy and short-tempered.
The answer to the question why we are aggressive when we are hungry is in the processes that take place in our body when it needs food.
Carbohydrates, proteins and fats, as well as everything you eat, is converted into simple sugars (such as glucose), amino acids and free fatty acids. These nutrients pass through the bloodstream and are delivered to the organs and tissues that use them for energy. As the time of your last meal passes, the amount of nutrients that circulate in the bloodstream begins to decline. If glucose levels drops, our brain react.
Our brain sends instructions to some organs to synthesize and increase the hormones , which will again increase the amount of glucose in the bloodstream. One of these hormones, among other is adrenaline, which is released into the bloodstream.
Feel of hunger usually will not keep you long, because our body finds other sources of glucose. It start to breaking down fat reserves in the quest for power and energy, some of them are converted into ketones, products of fat metabolism. Ketones serve to keep the control of the attacks of hunger, because the brain can used them as fuel instead of glucose.
The easiest way to deal with hunger is to eat something before you become too much hungry. As a reminder, fast food is not the best solution for this problem. The popular “junk food” rapidly increases glucose in blood, but after fall even faster. This allows you to feel even hungrier and also as everyone knows, fast food is not very healthy meal.
