Background: The Forbes equation relating fat-free mass (FFM) to fat mass
(FM) has been used to predict longitudinal changes in FFM during weight change but
has important limitations when paired with a one dimensional energy balance
differential equation. Direct use of the Forbes model within a one dimensional energy
balance differential ... read moreequation requires calibration of a translate parameter for the
specific population under study. Comparison of translates to a representative sample
of the US population indicate that this parameter is a reflection of age, height,
race and gender effects.
