Frequently asked questions

What makes Katch-McArdle different from Mifflin-St Jeor?: Katch-McArdle uses lean body mass rather than total body weight, so it is more accurate for people who know their body fat percentage. Mifflin-St Jeor only needs weight, height, age, and sex.
How do I find my lean body mass?: Subtract fat mass from total weight. Use our Lean Body Mass Calculator to estimate LBM from height, weight and sex using the Boer formula.
