Fuel Partitioning Mastery

Meaning

Fuel Partitioning Mastery is the physiological control over how ingested macronutrients are distributed between storage (adipose tissue), immediate use (oxidation), and tissue accretion (muscle protein synthesis). Optimal partitioning favors nutrient use for anabolic processes and energy expenditure over fat storage, even with caloric surplus. This state reflects superior insulin sensitivity and effective utilization of hormonal signals governing substrate fate. Achieving mastery ensures that dietary inputs maximally support lean mass maintenance and metabolic health.
