Creator debunks nutrition comment directly from @reecebrah
The creator responds directly to a user's comment, which is displayed on screen, claiming the brain runs better on ketones. He refutes this by explaining that the brain always requires a certain amount of glucose, even in deep ketosis. He then details the catabolic process of gluconeogenesis, where the body breaks down muscle and bone tissue to create the necessary glucose if it's not consumed through diet.

Your brain actually cannot run only on ketones. Even in the deepest ketosis, you can only run on about 70% ketones. You still need glucose, which means your body still has to make glucose by tearing down amino acids and spiking cortisol and adrenaline. You cannot function without glucose. So either you eat it or you make it through catabolic processes that involve stripping muscle and bone tissue of amino acids.
