Mobile phone with fat measuring function and the fat measuring method thereof

A fat measuring method performed on a mobile phone, the mobile phone including a mobile phone control module, a display unit, a fat measuring control circuit, a constant current electrode pair, a voltage measuring electrode pair, and a memory device, both the display unit and the fat measuring control circuit being coupled to the mobile phone control module, both the constant current electrode pair and the voltage measuring electrode pair being coupled to the fat measuring control circuit, the memory device being coupled to the mobile phone control module and storing a range of target body fat percentage predetermined by a user, the method comprising the steps of:

• accessing the user's personal data including at least a weight data by the mobile phone control module;
• touching the constant current electrode pair and the voltage measuring electrode pair by the user, allowing the fat measuring control circuit to measure a bioelectric impedance of the user;
• generating a body fat percentage of the user according to the bioelectric impedance and the user's personal data by the fat measuring control circuit, and displaying the body fat percentage on the display device;
• and
• determining if the user's body fat percentage is outside the range of target body fat percentage;
• if yes, selectively imposing restrictions on the length of talk time or the number of calls the user can make within a specific period of time by the mobile phone control module.

A mobile phone for measuring a user's body fat percentage according to the user's weight data, comprising:

• a mobile phone control module;
• a display device coupled to the mobile phone control module;
• a fat measuring control circuit coupled to the mobile phone control module;
• a constant current electrode pair coupled to the fat measuring control circuit;
• a voltage measuring electrode pair coupled to the fat measuring control circuit;
• and
• a memory device which is coupled to the mobile phone control module and stores an authorized body fat percentage for the user,
• wherein when the user touches the constant current electrode pair and the voltage measuring electrode pair, the fat measuring control circuit applies a predetermined current to the constant current electrode pair, causing the voltage measuring electrode pair to generate a measured voltage, the user's body fat percentage is then generated according to the measured voltage and the user's weight data, and the body fat percentage is displayed on the display device,
• wherein the mobile phone control module terminates a normal booting procedure of the mobile phone if the user's body fat percentage measured by the mobile phone is beyond a tolerance error of the user's authorized body fat percentage.
