Yes, fat is a form of energy storage in the body. It is one of the primary sources of energy, especially during prolonged periods of low food intake or high physical exertion. Fats are dense in calories, providing about 9 calories per gram, which is more than double the calories provided by carbohydrates or proteins. In addition to being an energy source, fats are important for the absorption of fat-soluble vitamins (A, D, E, and K) and for insulating and protecting the body’s organs.
