The word “calorie” is everywhere. We see it on food labels, fitness apps, diet plans, restaurant menus, and even on exercise machines. You may hear people say: “This food has too many calories.” “I burned 300 calories today.” “I am trying to eat fewer calories.” “How many calories should I eat per day?” But what exactly is a calorie?
