Abstract

The purpose of this study was to determine whether there is a difference in percent body fat measured by hand-to-hand bioelectrical impedance analysis (BIA), dual-energy x-ray absorptiometry (DXA), and air displacement plethysmography (ADP) both before and after consumption of a liquid or semisolid meal. Body composition of 32 participants was measured both before and after consumption of 350-mL Gatorade or cereal with milk. There was no significant difference in percent body fat measured before or after the food or fluid load by DXA, BIA, or ADP. Ingesting a small amount of food or fluid just before measurement does not appear to influence DXA, BIA, or ADP results.
