A device or tool, either physical or digital, designed to estimate the proportion of body mass that is comprised of adipose tissue. As an illustration, a device might utilize skinfold measurements, bioelectrical impedance analysis, or equations incorporating anthropometric data to derive this estimation. The output is generally expressed as a percentage of total body weight.
Knowledge of body fat composition is a valuable metric in assessing overall health and fitness levels. Monitoring changes in this metric can provide insights into the effectiveness of diet and exercise regimens. Historically, assessments of body composition were limited to laboratory settings; however, advancements in technology have made these calculations more accessible and convenient for general use.
