Brain and starvation: During starvation, a significant pa (60-70%) of the energy requirement of the brain is then met by ketone bodies (Fig. 8.1) Brain and acetoacetate: The brain is unable to utilize fatty acids as a source of fuel since the fatty acids complexed to albumin are unable to traverse the blood-brain barrier.
