Calories

Calories are a measurement of energy. Your body needs a certain amount of energy each day. Energy comes from food in the form of calories. Calories let you function and do your daily activities. After your body meets its needs, it stores extra calories as fat.

Your weight stays steady when your body takes in the same number of calories that it burns. To lose weight, you have to use up more calories than you take in.
