<h3>
Why fat is an important source of energy?</h3>
- An essential part of a diet intended to support activity is fat. Nine calories per gram of dietary fat and 3,600 calories per pound of stored fat, respectively, are available from fat.
- It is our largest store of energy due to its high caloric density (the highest of all nutrients) and almost limitless capacity for storage.
- Although dietary fat has been linked to a number of health issues, it is actually a necessary ingredient for good health.
- The largest reserve of stored energy for activity is found in adipose tissue (stored fat), which also protects nerves, cushions and insulates internal organs, transports certain vitamins (A, D, E, and K) throughout the body, and cushions and insulates internal organs.
