Question
How do we know that we are hungry and that we should eat?

Answer

When the food absorbed in the blood gets exhausted, after release of energy, the message reaches the brain via the network of nerves. Due to this, the brain then gets the signal that the body needs food. We realise we are hungry and we need to eat food.
