FM increases faster than FFM as a function of weight.

<p>Relationships between predicted body composition and weight (abscissa) to DXA-determined values (ordinate) for the full DXA population (IG + CV) are linear and show that with increasing mass, TF and FFM increase at similar rates which are less than for the total FM. Predicted weight is the sum of FFM and FM (see text for <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0024017#s3" target="_blank">discussion</a>).
