Explanation: 

Detailed explanation-1: -The best biological explanation for why the human body stores fat is that it is a fuel reserve during periods when food is scarce.

Detailed explanation-2: -Dietary fats are essential to give your body energy and to support cell function. They also help protect your organs and help keep your body warm. Fats help your body absorb some nutrients and produce important hormones, too.

Detailed explanation-3: -Energy Storage While glycogen provides a ready source of energy, lipids primarily function as an energy reserve. Glycogen is quite bulky with heavy water content, thus the body cannot store too much for long. Fat is used for energy during exercise, especially after glycogen is depleted.

Detailed explanation-4: -Fats are stored in the human body in adipose tissue. Adipose tissue acts as a central metabolic organ and regulates the energy homeostasis of the body. During starvation or a long period of fasting adipose tissue gets broken down to give energy to the body.

Detailed explanation-5: -Fat helps the body absorb vitamin A, vitamin D and vitamin E. These vitamins are fat-soluble, which means they can only be absorbed with the help of fats. Any fat that’s not used by your body’s cells or turned into energy is converted into body fat.
