Metabolic Switching

Meaning

Metabolic switching is the dynamic physiological process where the body rapidly and efficiently shifts its primary energy substrate from one source to another, most commonly moving from glucose utilization to the oxidation of fatty acids and ketones. This fundamental adaptability is a key indicator of metabolic flexibility and is typically triggered by periods of fasting, intense exercise, or caloric restriction. In hormonal health, the capacity for efficient switching is crucial for maintaining stable blood glucose levels, optimizing body composition, and enhancing cellular resilience.
