Energy Utilization

Meaning

Energy Utilization is the fundamental physiological process by which cells extract chemical energy from macronutrients—carbohydrates, fats, and proteins—and convert it into adenosine triphosphate (ATP), the primary energy currency required for all biological functions. In the context of hormonal health, the efficiency and substrate preference of this process are profoundly influenced by hormones like thyroid hormone, insulin, and cortisol. Optimal energy utilization ensures robust cellular function, supports metabolic rate, and prevents the accumulation of metabolic waste products, which is crucial for sustained vitality and longevity.
