Definition:
A calorie is a unit of energy. In the context of food and nutrition, a calorie represents the amount of energy that is provided when a particular food item is consumed and metabolized by the body. The term is often used in two forms: the small calorie (cal), which is the amount of energy needed to raise the temperature of 1 gram of water by 1 degree Celsius, and the large Calorie (kcal or Cal), commonly used in food labeling, which is equivalent to 1,000 small calories.
