Brain Energy Utilization

Meaning

Brain Energy Utilization describes the rate and efficiency at which the central nervous system consumes metabolic substrates, predominantly glucose, but also ketone bodies and lactate, to sustain neuronal and glial function. The brain is an energetically demanding organ, and its utilization rate is a critical determinant of cognitive performance, emotional regulation, and neuroplasticity. Optimal utilization ensures stable ATP production, preventing energy deficits that can manifest as brain fog, fatigue, or mood dysregulation, which are often linked to systemic hormonal imbalances.
