Fuel Matrix

Meaning

The Fuel Matrix refers to the complex, integrated system of metabolic pathways that dictates which macronutrients—carbohydrates, fats, or proteins—are utilized by the body and brain for energy production at any given time. This matrix reflects the body’s metabolic flexibility, which is its ability to efficiently switch between these substrates in response to hormonal signals and energy demands. Optimal hormonal health is characterized by a highly flexible and efficient fuel matrix.
