      It is all about your brain and your stomach. When you stomach is empty and rumbling, it sends signals to your brain which tells your body that you need some food. Food is energy, so we need to eat to function.

      There are also a number of hormones that control our appetite. For example there is a hormone called GhRelin (also known as the “hunger hormone”, that is produced by our stomach and released in your bloodstream. When our stomach is empty, high levels of ghrelin are released in the bloodstream; ghrelin travels in the bloodstream to tell a specific part of your brain, the hypothalamus, that your stomach is empty. So your brain sends out the message to you: “you are hungry, go eat!”. After you eat, ghrelin levels in your bloodstream are very low, while other hormones (like leptin, the “satiety hormone”) will be high.

      We have different reactions continuously happening in our bodies. All of these need energy. As energy is used up, more must be made from our food. Therefore, signals, such as hormones, can be sent to our brains to tell us we are hungry. One of the signals is a hormone, called ghrelin, it is used to signal to the brain that your stomach is empty and needs food.

      In simple terms, being hungry is just a way of our mind telling us that our battery(glucose) has run out. Glucose is like a currency of energy similar to your phones and ipads. Once it is low, our body needs recharging. This is regulated by body sending signals to the brain to feed it.
      Two major signals of hunger that we feel are as below:
      Specialized motions in the stomach sweep up undigested food followed by final phase secreting a hormone called motilin which the rumbling in our tummies and hunger pangs.

      Another hormone is ghrelin which activates a specific region of the brain, which tell us that we are hungry.
