What is Lean Body Mass?
Lean Body Mass (LBM) is your total body weight minus your fat mass. It includes your muscles, bones, organs, skin, and water. Tracking LBM helps you ensure you're losing fat, not muscle, during weight loss.
Why LBM Matters
- Preserving LBM during weight loss maintains your metabolism
- Higher LBM means more calories burned at rest
- LBM tracking ensures you're losing fat, not muscle
LBM vs Total Weight
Scale weight doesn't tell the whole story. Two people at the same weight can look completely different based on their lean mass vs fat mass ratio. Focus on body composition, not just the number on the scale.
