Final answer:
The most accurate way of measuring body fat is the Dual-energy X-ray absorptiometry (DEXA) technique, which can determine fat content by directing X-ray beams through the body and analyzing the energy absorbed.
Step-by-step explanation:
The most accurate way of measuring body fat among typical testing methods is the Dual-energy X-ray absorptiometry (DEXA) technique. DEXA not only measures bone density, but it can also determine fat content by directing two low-dose X-ray beams through the body and analyzing the energy absorbed from the beams. This method uses mathematical formulas to accurately estimate fat content.
