The number of kilocalories (kcals) you burn depends on the type of exercise you do. (A kcal is the same amount of energy as a calorie, except that the custom is to use the term "calories" when we're talking about food and "kilocalories" when we're talking about exercise. They're both the same amount of energy.)
