A body mass index (BMI) calculator body fat machine is an electronic device that estimates an individual’s body fat percentage using bioelectrical impedance analysis (BIA). For example, a common type of body fat machine measures the electrical resistance of a person’s body, with higher resistance indicating a higher percentage of body fat.
BMI calculators are relevant to overall health and wellness, facilitating an understanding of weight composition. The devices provide benefits such as monitoring progress toward fitness goals and assessing the effectiveness of dietary and exercise regimens. Historically, the development of BIA technology in the 1960s laid the foundation for modern body fat machines.
