When estimating body composition using bioelectrical impedance, dehydration caused by insufficient water intake, excessive perspiration, heavy exercise, or alcohol use can result in
A) an overestimation of fat mass
B) an underestimation of fat mass
C) no change in the estimate of fat mass

Question

Quizplus · Accepted Answer

Dehydration increases the body's electrical resistance, leading to an overestimation of fat mass because the bioelectrical impedance analysis assumes a higher proportion of non-conductive tissue (fat).
