Four Compartment Model of Fuller et al for Determining the Weight of a Patient's Body Fat

Parameters:

(1) body volume in liters (determined by air displacement in a BOD POD)

(2) total body water in liters (using deuterium dilution)

(3) body weight in kilograms

(4) bone mineral content in kilograms

fat weight in kilograms =

= (2.7474 * (body volume)) - (0.710 * (total body water)) - (2.0503 * (body weight)) + (1.4599 * (bone mineral content)

fat-free mass in kilograms =

= (body weight in kilograms) - (fat weight)

percent body fat =

= (fat weight) / (body weight) * 100%
