1. A method of measuring a body component of a user by a body component measuring apparatus including a band configured to be worn on the user, a first input electrode and a first output electrode which are disposed on an inside surface of the band and configured to contact a wrist of the user, a second input electrode and a second output electrode which are disposed on an outside surface of the band, a measuring circuit configured to apply a current to the first and second input electrodes and detect a voltage from the first and second output electrodes to measure a body impedance of the user, a plurality of acceleration sensors arranged in a direction perpendicular to a lengthwise direction of the body component measuring apparatus with a predetermined distance therebetween, and configured to sense whether the band is worn on a left wrist or on a right wrist by using a signal received according to a movement of the user, the method comprising:
sensing whether the band is worn on the left wrist or on the right wrist by using the signal received according to the movement of the user;
determining whether the first input electrode disposed on the inside surface of the band and the second input electrode disposed on the outside surface of the band are disposed farther from a center of a body of the user than the first output electrode disposed on the inside surface of the band and the second output electrode disposed on the outside surface of the band;
converting a disposition of the first and second input electrodes and the first and second output electrodes according to information about whether the band is worn on the left wrist or the right wrist;
providing the current between the first input electrode and the second input electrode;
measuring the voltage between the first output electrode and the second output electrode; and
determining the body impedance of the user based on the measured voltage.
