InBody uses a method called Bio-electrical Impedance Analysis (BIA) to measure body composition, which divides your weight into different components such as lean body mass and fat mass to assess health and nutrition.
A low-level electrical current is sent through the body.
The flow of the current is affected by the amount of water in the body.
The device measures how this signal is impeded through different types of tissue. Tissues that contain large amounts of fluid and electrolytes, such as blood, have high conductivity, but fat and bone slow the signal down.
The muscle in your body contains water, unlike fat, so the more muscle you have, the more body water. And the more body water you have, the lesser the resistance on the electrical current.
This information is then calculated to provide us with an easy to read body composition analysis results sheet that we can then use to track progress and communicate with members.
