What happens when the body uses its energy stores to provide cellular energy during a time of fasting, when there is not enough food energy?

Answer;

Fat cells break down stored fat and release fatty acids into the blood.

Explanation;

-When the body uses its energy stores to provide cellular energy during a time of fasting, when there is not enough food energy, the fat cells break down stored fat and release fatty acids into the blood.

-During short-term fasting the body burns free fatty acids from the body stores. As the muscle and liver glycogen stores become depleted, the body relies increasingly on fat to satisfy the body's energy needs.

When there is not enough food for the production of energy in the body, it would use the stored fat in the body to supply the needed energy to survive. This process is called the ketosis. Hope this answers the question. Have a nice day.
