Lean Body Mass and Bodyfat Calculator is: Accurate – Estimates body fat and lean body mass based on weight, height, age, gender, waist, iliac, and hips. Cost-Effective – Does not need expensive equipment or time-consuming analysis. Easy – Free online application only requires 5 measurements (weight, height, waist, iliac, and hips). Skin-fold measurements tend to be inaccurate because of loose skin after very large weight loss, so use this calculator for better results.
- Age – your age in years
- Height – your height without shoes
- Waist size – measure around your waist at your navel and also at the point midway between your navel and the bottom of your sternum, and take the average of these two measurements – that is your “Waist” measurement. Stand tall, but do not deliberately suck in your stomach or the estimation will be wrong.
- Iliac – measure around where your upper pelvic bones protrude the most (you can feel for them on either side of your waist/hips)
- Hips – measure around the hips at the maximum protrusion of the buttocks
