Abstract: A weight scale includes weight measurement means, storage means for storing a weight measurement value along with a measurement day and time, determination means for determining whether a fluctuation range of the weight measurement value in the same day is within a predetermined reference range, and display means for displaying a percentage of days determined that the daily weight fluctuation is within the reference range. In this manner, a trend in weight change can be grasped even with the measurement of a relatively short period.

Abstract: A health management guideline advising device includes input means for inputting personal information of a measuring subject; measurement means for measuring weight and body impedance of the measuring subject; estimation means for estimating a body composition distribution of the measuring subject from the inputted personal information and the measurement result by the measurement means; storage means for storing the measurement result by the measurement means and an estimation result by the estimation means with a measurement date and time, prediction means for predicting future weight fluctuation from the stored weight and the body composition distribution; and display means for displaying the predicted future weight fluctuation. Furthermore, target setting means for setting a weight reduction target and determination means for determining whether or not the weight reduction target can be achieved based on the prediction result by the prediction means are preferably arranged.

Abstract: A body composition measuring instrument includes a body composition calculating unit for calculating the body composition of a user by using a plurality of electrodes, a reference value storage region for storing information of a reference value related to the past body composition of the user, a display control unit for performing a control to display a position of the body composition during the time calculated by the body composition calculating unit in reference to a line showing the reference value on a predetermined graph, and a display section for providing a display corresponding to the output from the display control unit.

Abstract: A body composition measuring instrument includes a body composition calculating unit for calculating a body composition of a user by using a plurality of electrodes, a reference value storage region for storing information of a reference value related to the past body composition of the user, a display control unit for performing a control to display a position (BR1) of the body composition for this time calculated by the body composition calculating unit and a line (62) being a position of a reference value on a predetermined graph (G1 to G4), and a display section (15) for performing a display corresponding to an output from the display control unit.

Abstract: A server selects one of a predetermined display specification programs based on at least one of attribute information related to an attribute of the user, purpose information related to a usage purpose of the user, and measurement data of the user input from a communication terminal capable of exchanging data with a body composition measuring instrument. The selected display specification program is transferred to the body composition measuring instrument via the communication terminal. As a result, the display specification program of the body composition measuring instrument is updated.
