Glucose and the Brain

Glucose is the preferred energy source for the brain. The brain cannot store energy on its own, like some other body systems can. So, how does the brain function well for at least 30 days without its primary energy source?

You still eat carbs on whole30, they're in all plant-based foods to some degree, some have more than others (so, celery has fewer carbs than sweet potatoes or bananas, but there are carbs in all fruits, vegetables, and nuts). The body breaks down complex carbohydrates into simple forms, including glucose, which your body can use.
