to increase blood flow to the limbs for energy production to release energy from lipids stored throughout the body to transform stored proteins into carbohydrates for energy to contract muscles to create heat energy for the body
I gave my students this multiple choice question: Food provides calories needed by the body for energy. However, the body must use energy between meals when food is not consumed. What is the most likely response of the body when more energy is used than the calories consumed provide?

Only one answer is correct among these 4 choices:
- to increase blood flow to the limbs for energy production
- to release energy from lipids stored throughout the body
- to transform stored proteins into carbohydrates for energy
- to contract muscles to create heat energy for the body

Could you tell me which one is correct?

to release energy from lipids stored throughout the body
