Mobile terminal and method for controlling the same

A mobile terminal, comprising:

• a terminal body;
• a wireless communication unit configured to perform wireless communication with an external device that includes a first electrode unit positionable to permit contact with a part of a user's body;
• a second electrode unit arranged in the terminal body to permit contact with another part of the user's body to form a closed loop with the first electrode unit;
• and
• a controller configured to:
• obtain a body fat measurement using a voltage formed by a current flowing between the first electrode unit and the second electrode unit when the first electrode is in contact with the part of the user's body and the second electrode unit is in contact with the another part of the user's body, and
• control the second electrode unit to output the current to form an impedance when a specific function is executed, wherein the specific function is execution of a specific application for outputting a result of the body fat measurement.
