From Nutrition and Dietetics: Macronutrients and energy balance · Carbohydrates, Proteins and Fats
After several days of fasting, which alternative fuel can the brain adapt to use for much of its energy?
- Ketone bodies made from fat
- Glycogen stored in brain cells
- Fatty acids taken straight from blood
Show the answer
Answer: Ketone bodies made from fat
The liver turns fatty acids into ketone bodies, which do cross into the brain and can cover a large share of its needs during prolonged fasting.
