A portable communication device combining body fat analyzer is disclosed, which is used to measure a value of body fat of a user thereof. A power source provides a first detecting current. A first detection node and a second detection node are located on a surface of the portable communication device and connected to the power source and contacted with the user, respectively. A current detecting module measures a second detecting current flown at the second detection node. A computing module generates a value of body fat of the user by computing the first and second detecting currents. A communication module transmits the generated value of body fat to a database at a distant end for a specific purpose.
