Equation of Fuller et al for Determining the Weight of a Patient's Body Fat

Description

Fuller et al used a number of body parameters to calculate the weight of body fat in a patient. The authors are from MRC Dunn Clinical Nutrition Centre and Addenbrooke's Hospital in Cambridge, England.

Parameters:

(1) body volume in liters (determined by immersion)

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

(3) body weight in kilograms

fat weight in kilograms =

= (2.22 * (body volume)) - (0.764 * (total body water)) - (1.465 * (body weight))

fat-free mass in kilograms =

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

percent body fat =

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