Explanation:
The plasma levels of fatty acids and ketone bodies increase in starvation, whereas that of glucose decreases. The metabolic changes on the first day of starvation are like those after an overnight fast. ... The liver obtains energy for its own needs by oxidizing fatty acids released from adipose tissue.

Answer:
During prolonged starvation, the primary source of glucose is gluconeogenesis from amino acids arising from muscle proteolysis. To spare glucose use (and thus spare muscle protein) most tissues of the body utilise fat-derived fuels (fatty acid and ketone bodies).
