Lean Body Mass (LBM) Calculator
Understanding Lean Body Mass (LBM)
Lean Body Mass (LBM) is the weight of your body minus your body fat. It includes the mass of your bones, muscles, organs, skin, and body water.
This calculator uses the Boer formula to estimate LBM:
- Males: LBM = (0.407 × Weight in kg) + (0.267 × Height in cm) – 19.2
- Females: LBM = (0.252 × Weight in kg) + (0.473 × Height in cm) – 48.3
Why is LBM important?
- It’s a better indicator of metabolic rate than total body weight.
- Helps in assessing nutritional needs and fitness progress.
- Useful for athletes and individuals managing weight.
The calculator also estimates your Body Fat Mass (Total Weight – LBM) and Body Fat Percentage ((Body Fat Mass / Total Weight) × 100).
Disclaimer: This is an estimate. For precise body composition analysis, consult a healthcare or fitness professional. Results can vary based on individual differences not accounted for by this formula.
Estimate your Lean Body Mass using the Boer formula.
Note: This calculator provides an estimate based on the Boer formula. Individual LBM can vary. Consult with a healthcare or fitness professional for personalized advice.
Your Estimated Lean Body Mass:
Lean Body Mass (LBM): kg
( lbs)
Derived Body Composition:
Body Fat Mass: kg
Body Fat Percentage: %
Notes:
- LBM estimation is based on the Boer formula.
- Body Fat Mass = Total Weight – LBM.
- Body Fat % = (Body Fat Mass / Total Weight) × 100.
- These are estimates. Consult professionals for precise analysis.
