Determining body fat percentage is an integral aspect of health and fitness assessments. The use of body fat machines has become prevalent, offering a convenient and non-invasive method to measure body fat. The accuracy of these machines, however, remains a subject of debate.
Body fat machines utilize advanced technologies such as bioelectrical impedance analysis (BIA), which measures the resistance of the body to an electrical current. This resistance is influenced by body composition, including fat mass and lean mass. Advancements in BIA technology have improved the accuracy of body fat machines over the years.
