Can you guess why do we feel hungry? Our body makes us feel hungry to tell us that it is in need of food. Why does it need food? Our body works all the time. It works when we play, eat, walk, breathe or run. Some parts of our body keep working even when we are asleep like our heart. It is beating all the time to pump blood. For all these works to do, out body requires a lot of energy. Where do we get this energy from? We get energy from the food we eat.
