Although it accounts for only about 2% of total body weight, the human brain consumes approximately 20% of the body's total energy, even during rest. To meet this high demand, the brain relies on several key fuel sources, with a complex and adaptive metabolic system designed to ensure a constant energy supply.

The human brain consumes roughly 20% of the body's total energy, despite making up only 2% of its weight, underlining its enormous metabolic demand. Understanding what is the best energy source for the brain is crucial for maximizing cognitive function, protecting against neurodegenerative diseases, and maintaining mental clarity.
