In the presence of glucose and ketones, the brain always goes for the glucose first.
In evolution, this is not what an "adaptation" is supposed to work. Eg, if fish are adapted to water, then they MUST have water to live. If humans are adapted to air, then we MUST have air to live. But apparently in the ketosis world, a body that is "fat adapted" still prefers glucose as a fuel source, and the only way to force this "adaptation" (if one could even call it that) is to deprive it of glucose.
Any evolutionary biologist wanna explain what this fat-adaptation is all about?
Ketosis and fat adaptation is strictly a "survival mechanism", which allows humans to survive during food shortages...Ketosis and fat adaptation was never meant to be used as a " healthy lifestyle choice", especially for people who are physically active, train, workout, compete in sporting events or are trying to achieve long term fat loss.
