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.


(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%
