Lean Mass Dominance

Meaning

Lean Mass Dominance is a state of optimal body composition characterized by a high proportion of metabolically active skeletal muscle mass and a low, healthy percentage of adipose tissue, particularly visceral fat. This physiological profile is clinically significant as it is strongly correlated with superior metabolic health, enhanced insulin sensitivity, and overall longevity. Achieving this state indicates effective anabolic signaling and efficient substrate utilization, signifying a robust metabolic engine. It represents a key therapeutic target in hormonal health and aging intervention, actively counteracting sarcopenia.
