If consuming a no carbohydrate diet, what would the brain use as its primary energy source? Where would these come from? Why does it use these and not fatty acids? - The brain would have to use ketone bodies as its primary energy source since it is unable to use carbohydrates and also unable to go through beta oxidation and utilize fatty acids. The ketone bodies would come from the liver. Your friend rarely drinks alcohol, but at a social event is drinking heavily. How would he/she be metab...
