Dual Fuel Engine

Meaning

The term Dual Fuel Engine, in the context of human physiology and metabolic health, is a clinical metaphor describing the body’s optimal capacity to efficiently utilize both glucose (carbohydrates) and fatty acids (fats) as primary energy substrates for cellular function. This metabolic flexibility signifies a highly adaptable and healthy system, allowing the body to seamlessly switch between fuel sources based on nutritional availability and energy demand, a state known as metabolic flexibility. Achieving this dual fuel capacity is crucial for sustained energy, weight management, and preventing insulin resistance, which occurs when the system becomes rigidly reliant on glucose.
