Bioelectrical
Impedance Analysis or BIA is considered one of the most exact and
accessible methods of screening body fat. In conventional BIA, a
person is weighed, then weight, height, age and gender are entered in
a computer. While the person is lying down, electrodes are attached to
various parts of the body and a small electric current is discharged
that measures the impedance or resistance to muscle and fat.  The more muscle, the lower the
value as the electricity passes easily through lean mass. A formula in
the computer converts all of the data to indicate what percentage of
the body is fat.
Tanita has patented a
revolutionary new way of measuring BIA that is faster, easier, less
intrusive and includes a precision scale as part of the one-step
process. Height, age and gender are entered into a computer and the
person steps on the scale. Electrodes in the foot sensor pads send a
low, safe current through the body. Weight and body fat content are
calculated simultaneously in seconds.
