1. A device to provide data as a guide to health management, comprising:

  • a main unit;

    a pair of hand grips, connected to ends of said main unit, including first and second electrodes connected to apply a high-frequency signal and third and fourth electrodes connected to measure a resistance of a human body; and

    a foot electrode unit, connected to said main unit, including fifth and sixth electrodes connected to apply a high-frequency signal, and a seventh connected to measure an electrical potential developed across said human body,said main unit comprising;

    a signal generator operable to produce a first high-frequency signal which passes through both a shallow part of the body where subcutaneous fat is located and a deeper part of body where visceral fat is located and a second high-frequency signal which passes mainly through the deeper part of the body,an electrode selecting device including switches connected to establish connections to two of said electrodes;

    a frequency selecting device connected to select which of said first or second high frequency signals will be applied between two or more of said first, second, fifth and sixth electrodes;

    an impedance measuring device connected to measure an impedance between two or more of said third, fourth and seventh electrodes;

    a calculating device connected to calculate a fat mass based on a relationship between an impedance measured by said impedance measuring device when said first high-frequency signal is applied and an impedance measured by said impedance measuring device when said second high-frequency signal is applied; and

    a display device connected to display a result obtained by said calculating device.
