Over 60% of the body's total glucose metabolism is used by the brain alone. This essential energy is supplied by direct sources of glucose, which can be acquired from the food we eat or produced internally through complex metabolic pathways. Understanding these origins is key to comprehending human energy regulation and overall health.

The human brain alone requires approximately 100 grams of glucose per day for energy. This demand for glucose persists even during periods without carbohydrate intake, revealing the body's sophisticated backup plan known as gluconeogenesis, which explains what a protein is converted to glucose called. This vital metabolic pathway ensures a continuous supply of glucose for essential organs and bodily functions.
