Fat-to-Muscle Ratio

Meaning

The Fat-to-Muscle Ratio is a clinically relevant and highly informative metric representing the proportion of an individual’s total body mass composed of metabolically inert adipose tissue (fat) relative to their lean, functional muscle mass. This specific ratio is a far more accurate and sensitive indicator of metabolic health, hormonal balance, and longevity potential than the simple, crude Body Mass Index (BMI), as it directly reflects the functional quality of body composition. A highly favorable ratio, characterized by robust muscle mass and appropriately low body fat, is strongly correlated with improved insulin sensitivity, superior endocrine function, and a significantly reduced risk of age-related metabolic diseases.
