About Lean Body Mass

Lean Body Mass (LBM) is the weight of your body minus all the weight due to fat mass. It includes the weight of your organs, bones, muscles, and water in your body.

Why is LBM important?

  • It's a key indicator of overall health and fitness
  • Used to calculate basal metabolic rate (BMR)
  • Helps in determining nutritional needs
  • Useful for tracking progress in fitness and weight loss programs

This calculator uses your weight and body fat percentage to estimate your lean body mass. For accurate body fat percentage, consider using methods like DEXA scans, hydrostatic weighing, or professional skinfold measurements.
