Frequently Asked Questions
What is lean body mass?
Lean body mass is your total body weight minus fat mass — it includes muscle, bone, organs, and water. It is a useful baseline for setting protein intake targets and tracking body composition changes.
Why use the Boer formula?
The Boer formula is one of the most widely validated equations for estimating lean body mass from just weight and height, without needing specialized body composition equipment like a DEXA scan.
How can I use my lean body mass result?
Many fitness and nutrition guidelines base protein intake recommendations on lean body mass rather than total body weight, since it more accurately reflects your muscle tissue that actually needs protein to repair and grow.
