The calorie is a unit of energy defined as the amount of heat needed to raise a quantity of water by one degree of temperature. There are two versions of the unit in use, which has led to some confusion. It is historically defined as the amount of heat energy needed to raise the temperature of one gram of water by one degree Celsius. This is now known as the small calorie and is spelled with a lower case ''c''. Today it is most widely used in nutrition as the large Calorie, where it is spelled with a capital ''C'' and is defined as the amount of heat needed to raise the temperature of one kilogram of water by one degree Celsius. ie the Calorie in nutrition is equal to 1000x the calorie used in traditional physics.

Children have widely varying calorie needs based on their age, size, and activity level.

Whereas the average toddler requires 1,200–1,400 calories per day, the average moderately active teenager requires 2,000–2,800 calories per day. Active teenage boys require even more.

Children who are growing and developing normally and engage in regular physical activity usually don’t need to count calories. When they’re provided with a range of healthy options to eat, most moderately active kids naturally eat the amount of food their body requires.
