Fat serves as a concentrated source of energy. Each gram of fat yields 9 calories of energy (twice the double amount yielded by carbohydrates and protein). Any excess of energy is stored in the form of fat or adipose tissue.
Fats or lipids are the most concentrated form of all energy giving foods. They constitute an important part of our daily diet and supply about 10-30% of our energy needs.
The main function of fats in the body is to provide energy: By supplying energy, fats save proteins from being used for energy and allow them to perform their more important role of building and repairing tissues. Fats on oxidation provide almost twice as much energy as that given by carbohydrates.
