Metabolic Flexibility Metrics

Meaning

Metabolic Flexibility Metrics are a set of quantifiable physiological measures that accurately assess the body’s efficiency in rapidly and appropriately switching between different primary fuel sources, specifically glucose and fatty acids, in response to varying nutritional and energetic demands. High metabolic flexibility indicates superior health, cellular resilience, and optimal energy balance, while metabolic rigidity is a core feature of insulin resistance and the broader metabolic syndrome. These metrics serve as crucial indicators of overall metabolic fitness and longevity potential.
