Lean Body Mass (LBM) Calculator
Lean Body Mass is the total weight of everything in your body **except fat** — including muscle, bones, water, and organs. It’s a valuable metric for tracking fitness progress, planning protein intake, and understanding your body composition more accurately than weight alone.
Estimate Your Lean Body Mass
💡 Understanding Lean Body Mass
- Higher LBM typically means more muscle and a stronger metabolism.
- This is an **estimate** — tools like DEXA scans give more precise body comp data.
- Use your LBM to estimate protein needs (typically 0.7–1.0g per pound of LBM for active individuals).
