Katch-McArdle Calculator

Precise BMR calculation based on lean body mass - ideal for athletes

How the Katch-McArdle Formula Works

This formula calculates BMR based on lean body mass rather than total body weight, making it more accurate for people who know their body fat percentage. It's particularly useful for athletes and physically active individuals.

Katch-McArdle: BMR = 370 + (21.6 × lean body mass)
Lean Body Mass: Weight(kg) × (1 - body fat %/100)
