Body fat percentage is the proportion of your total body mass that is fat tissue. Unlike BMI, body fat percentage distinguishes between fat and lean mass (muscle, bone, water), making it a more accurate indicator of fitness and health risk.
💡
Tip: Waist circumference alone is a strong predictor of cardiovascular risk. Men with waist >40 in (102 cm) and women >35 in (88 cm) have significantly elevated risk.

Fun Fact
Elite marathon runners typically have 5–11% body fat (men) or 10–18% (women). However, very low body fat impairs hormone function and immune response.
