No, according to the product description page on the 24 hour fitness site, it does not measure body fat:

The things that bodybugg does do are as follows:

* pedometer/accelorometer: The armband contains an accelerometer. The accelerometer measures motion, such as steps being counted. It measures how you move from multiple perspectives to give a fuller understanding of movement. Steps are counted using the accelerometer to measure the distinct patterns created by running and walking. It is really much more than a pedometer actually.
* galvanic skin response: When you sweat, your skin becomes more electrically conductive. This measurement helps the device understand how active you are.
* skin temperature: There’s an electronic thermometer inside your armband that helps you know how hot you are.
* heat flux: When you move, your muscles produce heat. You measure the heat that’s flowing from your body into the environment.
