What is Hunger

A feeling of discomfort or weakness caused by lack of food, coupled with the desire to eat. It’s a physical reaction caused by the chemical changes in the body related to a naturally low level of glucose in the blood several hours after eating. Hunger is also an instinctive, protective mechanism that makes sure that your body gets the energy it requires to function properly. It is not easy to control hunger, and ignoring hunger can cause serious results. Hunger can cause dizziness, fatigue, and low blood sugar.

The feeling of hunger is your body’s way of telling you that you need food. It can also send some singles such as rumbling of the stomach, which is known as hunger pangs.

Main Difference - Hunger vs Appetite

What is Appetite

Appetite is the natural desire to satisfy a bodily need, especially for food. It is a sensory or psychological reaction that stimulates an involuntary physiological response. In other words, if you see or smell a delicious, delectable food, your mouth will start salivating, your stomach will contract; you’ll practically taste the food and feel its texture. Even thinking about that food will elicit this response.

This is a conditioned response to food – a coordination between the brain and the stomach. But appetite is not an urgent need for food; it doesn’t cause you dizziness or fatigue since it is not a physical need like hunger. Thus, appetite can be controlled and ignored. If you learn to have control over your brain, this is not difficult at all.
