A body fat measurement device is an instrument designed to calculate the percentage of fat mass in a human body. The most accessible and commonly used method is bioelectrical impedance analysis, which measures the resistance to a small electrical current passing through the body.
Accurate body fat measurements are crucial for assessing overall health, managing weight and fitness goals, and diagnosing certain medical conditions. Historical breakthroughs, such as the invention of dual-energy X-ray absorptiometry (DEXA), have enhanced the precision and accessibility of body fat measurement techniques.
