The BF-350 from Tanita is an FDA cleared and Health Canada approved body composition analyzer. Using bioelectric impedance analysis (BIA), it is able to accurately assess an individual’s weight and body fat percentage. The BF-350 transmits a very low, safe electrical signal from four metal electrodes through the feet to the legs and abdomen. The electrical signal passes quickly through water that is present in hydrated muscle tissue but meets resistance when it hits fat tissue. This resistance, known as impedance, is measured and input into scientifically validated Tanita equations to calculate body composition. The algorithm includes additional information such as gender, age, and height alongside weight and impedance values and were developed by collecting data from thousands of people worldwide to ensure the most reliable results possible.
