Heymsfield et al reported an equation for estimating total body fat using a multicompartment model. The authors are from St. Luke's Roosevelt Hospital and The Flinders University of South Australia.

Patient selections: adolescents and adults, male and female, Black and White



(1) body density from hydrostatic weighing

(2) total body water in liters by deuterium dilution

(3) total body bone mineral content (BMC) in kilograms from DXA (dual-energy X-ray absorptiometry)

(4) body weight in kilograms


body volume in liters =

= (body weight) / (body density)


total body fat in kilograms =

= (2.513 * (body volume)) - (0.739 * (total body water)) + (0.947 * (bone mineral content)) - (1.79 * (body weight))
