Fasting Induced Fat Oxidation

Meaning

Fasting induced fat oxidation is the physiological process where a period of nutrient abstinence triggers the preferential breakdown and utilization of stored body fat as the primary fuel source for energy production. This metabolic shift is a core component of metabolic flexibility and a necessary survival mechanism, ensuring energy supply when external nutrients are unavailable. Clinically, enhancing this capacity is a major therapeutic target for improving body composition and managing insulin resistance. The efficiency of this process reflects the body’s ability to transition smoothly between fed and fasted states.
