Calories are a unit of energy. We need it to stay warm, move around and control other processes in our bodies. It is important to take in enough energy (calories) to keep your body functioning optimally. If you eat more than you use, you can either gain or lose weight if you don't eat enough. How much you need depends on your weight, gender and how active you are.
