I want to know the answer to the following question:
Where does the brain usually get most of its energy from inside the body?
All the background I'm provided with is that "The brain typically gets most of its energy from oxygen-dependent metabolism of glucose (i.e., blood sugar), but ketones provide a major alternative source, together with contributions from medium chain fatty acids (caprylic and heptanoic acids), lactate, acetate, and possibly amino acids.". Is that enough to answer the question?
