Neural Fuel Switching

Meaning

Neural Fuel Switching is the physiological capacity of the brain to seamlessly and efficiently transition its primary energy source between glucose and ketone bodies in direct response to changes in nutrient availability or metabolic demand. This metabolic flexibility is a critical mechanism for ensuring sustained, high-level cognitive function, especially during periods of fasting, intense mental exertion, or carbohydrate restriction. The ability to utilize ketones offers measurable neuroprotective benefits and can enhance mental clarity due to the brain’s preference for them as a highly efficient fuel source.
