Functions of Fats
The main function of fats are to supply energy for the body so protein doesn't have to be used for energy and can be used to build and repair tissue instead. Fats in an oxidation process provide almost twice as much energy as carbohydrates. Some fats also supply the body with essential fatty acids.
