Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a health management guideline advice device.
[0002]
[Prior art]
Conventionally, a health management guideline advice device (for example, a weight scale disclosed in Design Gazette No. 1021758) premised on use among a plurality of users is used for individual data (height, weight, etc.) of a plurality of users. , Age, etc.), body data measurement device, personal data stored in the memory and body data measured by the measurement device, body fat mass, lean mass, water content, basis A control unit that calculates health evaluation data such as metabolic rate and a display unit that displays the calculated data for health evaluation are provided.
[0003]
Each user of the health care guideline advice device stores personal data in a memory in advance, and calls the corresponding personal data when measuring biometric data by the measuring device. Thereafter, when the user measures biometric data with the measuring device, based on the personal data and the biometric data, health evaluation data such as body fat, lean mass, body fat percentage, water content, basal metabolic rate, etc. Value relating to body fat) is calculated and displayed on the display unit. Thereafter, the user can obtain guidelines for his / her health management by referring to the health evaluation data displayed on the display unit.
[0004]
In recent years, many health management guideline advice devices (referred to as “combination type advice devices”) that combine weight scales and body fat scales have been distributed in the market. The combination type advice device can measure a weight value, which has been one of personal data set by a user, together with biological data (for example, a biological impedance value) provided for processing by the control unit. . For this reason, improvement in the accuracy of the health evaluation data calculated by the control unit can be expected.
[0005]
The scale combination advice device is roughly divided into (1) a configuration related to weight measurement (weight scale unit) and a configuration related to biometric data measurement (biometric data measurement unit). What can be measured almost simultaneously (for example, refer to Japanese Patent Publication No. 5-49050: hereinafter referred to as “preceding example 1”) and (2) a weight scale unit and a biological data measurement unit are separated from each other. And biometric data cannot be measured at the same time (for example, see Japanese Patent Application Laid-Open No. 7-108040: hereinafter referred to as “preceding example 2”).
[0006]
In the first example, as a normal operation procedure, first, the user depresses a personal number switch that is also used as a power switch (specifies a personal number). After that, the user is placed on the weight scale unit, and the body weight and the biological data are measured at the same time, and the body fat, the lean body mass, the body fat rate, which are obtained by the calculation using the measurement result of the body weight and the biological data, Health evaluation data (values related to body fat) such as water content and basal metabolism are displayed.
[0007]
On the other hand, in the prior example 2, in order to improve the operability for the user, all the operation switches are often provided in the biological data measurement unit operated by hand. In addition, in the prior example 2, for the sake of convenience when measuring weight and biological data, even when the weight scale unit is turned off, when the user puts on the scale unit, the weight scale unit is automatically set. Some are designed to measure biometric data after the power is turned on and the weight of the user is measured.
[0008]
The operation procedure of the preceding example 2 is roughly as follows. That is, after measuring the body weight, the user calls his / her personal data registered in advance, and then measures the biometric data. Then, health evaluation data is calculated and displayed based on the measured weight value, biological data, and personal data. As described above, since the user's personal data is not required for the weight measurement, the personal data is generally called when the weight measurement is completed (i.e., when shifting from the weight measurement to the measurement of the biological data). Is called. At this time, in order to facilitate the work of identifying the user's own data from a plurality of personal data, for example, the user's name and user number, along with the user's height, weight, gender, age, etc. Personal data is displayed.
[0009]
[Problems to be solved by the invention]
However, the apparatus according to Prior Example 2 has the following problems. That is, in the preceding example 2, when the weight measurement is completed and the weight value of the user is confirmed, the confirmed weight value (referred to as “measured weight value”) is displayed on the display unit provided in the biological data measurement unit. The Thereafter, when the user calls his / her personal data, the contents of the personal data are displayed on the display unit.
[0010]
However, in the preceding example 2, since only one area (weight display area) for displaying the weight value is prepared on the display unit, when the weight value of the user is included in the personal data, the display is performed. The measured body weight value is erased from the display content of the display unit, and the body weight value (referred to as “registered body weight value”) included in the personal data is displayed in the body weight display area. Furthermore, once the measured body weight value was erased, it could not be displayed again. For this reason, the user may not be able to determine whether the weight value displayed on the display unit is the measured weight value or the registered weight value after the personal data is called.
[0011]
That is, in the prior example 2, the weight value is included in the content of the personal data so that the health evaluation data can be calculated by measuring the biological data without actually measuring the weight when calculating the health evaluation data. In addition, when the registered weight value is displayed after the measured weight value is displayed, the measured weight value is erased from the display content and cannot be displayed again. For this reason, the user may not know which of the measured body weight value and the registered body weight value is used for calculating the health evaluation data.
[0012]
Conversely, if the weight is measured after the personal data is called, the registered weight value is erased from the display content and the measured weight value is displayed, so the same problem as described above may occur. Had.
[0013]
The present invention has been made in view of the above-described problems, and after a user performs weight measurement and calling personal data, a value related to body fat is obtained using the bioimpedance value, the weight value, and the personal data. It is an object of the present invention to provide a health management guideline advice device that allows a user to clearly discriminate a weight value used for calculating a value related to body fat when calculated.
[0014]
[Means for Solving the Problems]
The present invention employs the following configuration in order to solve the above-described problems.
[0015]
That is, the first aspect of the present invention is a health management guideline advice device, a display unit, a body weight measuring unit for measuring the body weight of the subject, an impedance measuring unit for measuring the bioimpedance of the subject, A storage device that holds a weight value used for calculation of a value related to the body fat of the user as a registered weight value, and a weight value measured by the weight measuring unit and the registered weight value are values related to the body fat. And a control unit that simultaneously displays the weight value used for the calculation on the display unit.
[0016]
According to the first aspect of the present invention, since the measured body weight value (measured body weight value) and the registered body weight value are displayed at the same time, the measured body weight value and the registered body weight value can be distinguished and recognized. Become.

A second aspect of the present invention is a health management guideline advice device, a display unit, a weight measurement unit that measures the weight of the subject, an impedance measurement unit that measures the biological impedance of the subject, and a user A storage device that holds a weight value used for calculation of a value related to body fat as a registered weight value, and a weight value measured by the weight measurement unit and the registered weight value are calculated as values related to body fat. And a control unit that alternately displays the weight value provided on the display unit.
[0018]
In the first and second aspects, the measured body weight value and the registered body weight value may be selected by the person to be measured and used for calculation of a value related to body fat, and the measured body weight value is displayed. Alternatively, the measured body weight value may be forcibly used for calculation of a value related to body fat.
[0019]
Moreover, in the 1st and 2nd aspect, both can be distinguished by changing a display position, for example. At this time, if one of the registered weight value and the measured weight value is displayed with a smaller character than the other, the measured person can easily distinguish between the two. In addition, if a supplementary display indicating the type of weight value is displayed in the vicinity of at least one of the measured weight value and the registered weight value (for example, the word `` memory '' is displayed in the vicinity of the registered weight value), The distinction between the two becomes easier.

A third aspect of the present invention is a health management guideline advice device, a display unit, a body weight measurement unit that measures the body weight of the measurement subject, an impedance measurement unit that measures the bioimpedance of the measurement subject, and a user A storage device holding personal data including registered body weight values as body weight values used for calculation of values related to body fat, body weight is measured by the body weight measurement unit, and the measured body weight value is used as a measured body weight value. When the personal data is read from the storage device and displayed on the display unit after being displayed on the display unit, the control unit displays the measured weight value together with the personal data.
[0021]
According to the third aspect, the measured weight value is not erased from the display content by the display of the personal data.
[0022]
According to a third aspect of the present invention, the storage device holds personal data of a plurality of persons to be measured, and the control unit displays each measured weight value on the display unit, and then displays each individual from the storage device. When the data is read out and displayed individually on the display unit, the measured weight value may be displayed together with the individual data.
[0023]
In the third aspect, when the control unit displays the measured weight value together with personal data on the display unit, only the measured weight value may be displayed as the weight value.
[0024]

[0032]
The power supply 22 constantly supplies power to the control unit 24 and supplies operating power to the weight measurement unit 23 according to a command from the control unit 24 when the power switch 26 is pressed. In FIG. 2, the power supply line of the power source 22 is omitted.
[0033]
The weight measuring unit 23 outputs a load cell that outputs an electrical signal corresponding to the pressure due to the weight of the user placed on the measurement table 21, an amplification circuit that amplifies the output signal of the load cell, and an output signal of the amplification circuit that is analog / It comprises an A / D converter that performs digital conversion and inputs it to the control unit 24.
[0034]
The control unit 24 includes a microprocessor (MPU), a central processing unit (CPU), and the like, and controls the operations of the weight measurement unit 23 and the infrared light emitting diode 27 according to a predetermined control program held in the memory 25.
[0035]
The memory 25 holds a control program and is used as a work area for the control unit 24. When the infrared light emitting diode 27 receives data to be transmitted from the control unit 24 to the body fat scale 30, the infrared light emitting diode 27 generates and emits an infrared signal corresponding to the data.
[0036]
On the other hand, the body fat scale 30 includes a bioimpedance measuring unit 31, a control unit 32 having a memory 33 (corresponding to a storage device), an infrared sensor 35, a receiving circuit 36, a first power source 34, and a second power source 37. 1 is connected to the bioimpedance measurement unit 31, and the control unit 32 includes the power switch 4, the LCD 103, and the key input shown in FIG. The unit 104 is connected.
[0037]
The bio-impedance measuring unit 31 includes a constant current generating circuit for passing a high-frequency current between the electrodes 105 and 106 for energization, and between the electrodes 107 and 108 for measuring a potential difference when a high-frequency current is passed between the electrodes 105 and 106. And an A / D converter that converts the output signal of the amplifier circuit from analog to digital and inputs the signal to the control unit 32.
[0038]
The control unit 32 includes an MPU, a CPU, or the like, and executes a predetermined control program held in the memory 33. As a result, the control unit 32 controls the operation of the bioelectrical impedance measurement unit 31 and the LCD 103 in accordance with input signals from the power switch 4 and the key input unit 104.
[0039]
The memory 33 holds a control program and forms a work area for the control unit 32. In addition, the memory 33 is used by the control unit 32 for the calculation of health evaluation data (values related to body fat) such as body fat, lean mass, body fat percentage, water content, basal metabolism, etc. (Height value, weight value, age, sex) can be held for each of a plurality of users.
[0040]
Each user of the advice device 1 can register his / her personal data by operating the key input unit 104. However, the weight value may be registered by operating the key input unit 104, or the weight value measured by the weight scale 20 and displayed on the LCD 103 may be registered by pressing the record button 14.
[0041]
The infrared sensor 35 detects an infrared signal. The receiving circuit 36 extracts transmission data carried by the infrared signal from the infrared signal detected by the infrared sensor 35 and provides the control unit 32 with the transmission data.
[0042]
The first power source 34 is a constant power source and always supplies power to the infrared sensor 35, the receiving circuit 36 and the control unit 32. Thereby, the infrared sensor 35 and the receiving circuit 36 are in a state of always waiting for the reception of the infrared signal from the weight scale 20, and the control unit 32 is in a state of constantly monitoring the reception state of the infrared signal.
[0043]
The second power source 37 is a main power source for the body fat scale 30, and is activated by the control unit 32 when a specific signal is received, and supplies operating power to the LCD 103, the bioimpedance measurement unit 31, and the like. Note that the power supply lines of the first power supply 34 and the second power supply 37 are omitted in FIG.
[0044]
FIG. 3 is a flowchart showing an operation example (processing by the control unit 24) of the weight scale 20 shown in FIG. However, in this example, it is assumed that personal data (including registered body weight values) of a plurality of users is registered in the memory 35 of the body fat scale 30 before the processing shown in FIG.
[0045]
In FIG. 3, in step (hereinafter referred to as “S”) 01, the control unit 24 is always activated by supplying power from the power source 22, waits for the power switch 26 to be pressed, and then the power switch 26. If is pressed, the process proceeds to S02.
[0046]
In S <b> 02, the control unit 24 supplies power from the power supply 22 to each unit of the weight scale 20, generates a start signal for the second power supply 37 of the body fat scale 30, and gives the start signal to the infrared light emitting diode 27. As a result, an infrared signal including an activation signal is transmitted toward the body fat scale 30.
[0047]
In S03, the control unit 24 performs calibration processing (weight value zero adjustment) of the measurement unit.
[0048]
In S04, the control unit 24 determines whether or not the calibration process has been completed. If the calibration process has not been completed, the control unit 24 returns the process to S02, and if it has completed, advances the process to S05.
[0049]
In S05, the control unit 24 determines whether or not the calibration process is successful. If the calibration process is not successful, the process proceeds to S14. If the calibration process is successful, the process proceeds to S06.
[0050]
In S06, the control unit 24 generates a calibration end signal and transmits it from the infrared light emitting diode 27, and then advances the process to S07.
[0051]
In S07, when the user is placed on the measuring table 21 (see FIG. 1), the control unit 24 determines whether or not an error has occurred in the scale 20 (S08), and if an error has occurred. Advances the process to S14, and if no error has occurred, advances the process to S09.
[0052]
In S09, the weight value of the user is measured by the weight measurement unit 23 and the control unit 24, and in S10, the measured weight value is transmitted to the body fat scale through the infrared light emitting diode 27.
[0053]
In S11, the control unit 24 determines whether or not the weight value is stable. If the weight value is not stable, the process returns to S08. In this manner, the loop processing of S08 to S11 is repeatedly performed until a stable weight value is measured, and the weight values measured in each S09 are transmitted. Then, when the weight value is stabilized, the process proceeds to S12.
[0054]
In S <b> 12, the control unit 24 determines the weight value with a stable weight value, and transmits the determined weight value (determined weight value) from the infrared light emitting diode 27.
[0055]
In S <b> 13, the control unit 24 generates a weight measurement end signal and transmits it from the infrared light emitting diode 28 to the display 30. Thereafter, when a predetermined time (for example, 3 seconds) elapses, the power supply 22 is turned off by the auto power off function, and the transmission of the infrared signal from the infrared light emitting diode 27 is stopped. However, power supply to the control unit 24 is continued.
[0056]
On the other hand, when the process proceeds to S14, after the error code is transmitted to the body fat scale 30, the power supply by the power source 22 is stopped except for the power supply to the control unit 24 by the auto power off function. To do.
[0057]
FIG. 4 is a flowchart showing an operation example (processing by the control unit 33) of the body fat scale 30 shown in FIG. In FIG. 4, the control unit 33 is always activated by receiving power supply from the first power supply 34 at all times.
[0058]
In S001, after the second power source 37 is turned off (stopped), the control unit 33 determines whether or not the power switch 4 of the body fat scale 30 is pressed within a predetermined time (S002). If the switch 4 is pressed, the process proceeds to S005. If the switch 4 is not pressed, the process proceeds to S003.
[0059]
In S003, the control unit 33 determines whether or not an infrared signal is received from the weight scale 20 within a predetermined time. If the infrared signal is received, the process proceeds to S004, and if not, the process is performed. To S001.
[0060]
In S004, it is determined whether or not the infrared signal received in S003 is an activation signal for the second power source 37 (main power source). If not, the process returns to S001, and if so, the process is performed. Proceed to S005.
[0061]
In S005, the control unit 33 turns on the second power source 37 and advances the process to S006. As a result, the second power source 37 is turned on, and the second power source 37 supplies operating power to each part of the body fat scale 30 such as the LCD 103 and the bioelectrical impedance measuring unit 31. As a result, the LCD 103 is activated, and the display content at the time of activation is displayed on the display screen of the LCD 103.
[0062]
In S006, the control unit 33 determines whether or not the power switch 4 is pressed within a predetermined time. If the power switch 4 is pressed, the process returns to S001 to turn off the second power source 37. On the other hand, if the power switch 4 has not been pressed, the process proceeds to S007.
[0063]
In S007, the control unit 33 determines whether or not an infrared signal is received within a predetermined time. If the infrared signal is not received, the control unit 33 returns the process to S001, turns off the second power source 37, and receives it. Advances the process to S008.
[0064]
In S008, the control unit 33 determines whether or not the infrared signal received in S007 is the infrared signal transmitted from the scale 20, and if not, the process returns to S001, and if so, The process proceeds to S009.
[0065]
Here, as shown in FIG. 3, the weight scale 20 continuously transmits a calibration end signal, a body weight value, a final body weight value, and a measurement end signal (or error code) after the start signal is transmitted. For this reason, after receiving the activation signal, the body fat scale 30 is in a state of receiving the infrared signal from the weight scale 20 until the measurement end signal is received unless it is out of the transmission range of the infrared signal.
[0066]
Accordingly, in S009, the control unit 33 causes the LCD 103 to display a reception indicator. That is, the control unit 33 displays, for example, “receiving” characters on the display screen of the LCD 103. Thereafter, the process proceeds to S010.
[0067]
In S010, the control unit 33 determines whether or not the infrared signal received in S007 includes an error code. At this time, if an error code is included (S010; Y), the control unit 33 assumes that an error has occurred in the weight scale 20, and the content of the error code (error content generated in the weight scale 20). Is displayed on the LCD 103 (S015), the process proceeds to S017. On the other hand, if no error code is included (S010; N), the process proceeds to S011.
[0068]
In S011, the control unit 33 determines whether an error has occurred in the body fat scale 30, and if so (S011; Y), the error content generated in the body fat scale 30 is displayed on the LCD 103. After the display (S016), the process proceeds to S017. On the other hand, if no error has occurred (S011; N), the process proceeds to S012.
[0069]
In S012, if the infrared signal received from the scale 20 includes a weight value (excluding the confirmed weight value), the control unit 33 displays the weight value on the LCD 103, and then advances the process to S013.
[0070]
In S013, the control unit 33 determines whether or not an infrared signal including a measurement end signal has been received. If the infrared signal has not been received (S013; N), the process returns to S007, thereby performing steps S007 to S013. A loop process is performed to receive each of the calibration end signal, the body weight value, the final body weight value, and the measurement processing signal from the scale 20, and each weight value received after receiving the calibration end signal is displayed on the LCD 103. And the control part 33 advances a process to S014, when a definite body weight value is received and a measurement end signal is received (S013; Y).
[0071]
In S014, the control unit 33 causes the LCD 103 to display the determined weight value. At this time, the confirmed weight value is displayed blinking on the LCD 103, thereby allowing the user to recognize that the confirmed weight value. At this time, if the user presses the record button 14, the displayed determined weight value is registered in the memory 35 as personal data. Thereafter, the process proceeds to S017.
[0072]
In S017, the control unit 33 turns off the reception indicator. That is, after the reception indicator displayed on the LCD 103 is turned off, the process proceeds to S018.
[0073]
In S018, the control unit 33 determines whether or not the current body fat scale 30 mode is the body fat measurement mode. If not, the process returns to S001. , The process proceeds to S019.
[0074]
In S019, personal data selection processing by the user is performed. FIG. 5 is a diagram showing display contents of personal data displayed on the LCD 103, and FIGS. 6A to 6C are diagrams showing examples of screen display displayed on the LCD 103 in the personal data selection processing. . However, here, as an example, it is assumed that the personal data of the woman to whom the personal number “1” is assigned and the personal data of the man to which the personal number “2” is assigned are stored in the memory 35.
[0075]
In S019, when the user presses the data call button 11, personal data shown in FIG. That is, numbers indicating the height value, weight value, age, sex, and personal number assigned to each user are displayed on the display screen of the LCD 103.
[0076]
At the start of the process of S019, as shown in FIG. 6A, the determined weight value is displayed in the upper right of the display screen of the LCD 103. When the user presses the data call button 11, personal data corresponding to the personal number “1” is displayed on the LCD 103.
[0077]
That is, as shown in FIG. 6B, the display screen of the LCD 103 is displayed with the final weight value (measured weight value) displayed on the upper right, and corresponds to the personal number “1” on the left side. The user's height value, age, gender and personal number are displayed. Further, the weight value registered as the personal data of the personal number “1” (registered weight value) is lower than the confirmed weight value together with the characters “memory” indicating that the registered weight value is below the confirmed weight value. Displayed with small numbers.
[0078]
Thereafter, when the user presses the key corresponding to the personal number of the numeric keypad 7, the personal data corresponding to the personal number is displayed instead of the personal data of the personal number “1”. Here, assuming that the personal number assigned to the current user is “2”, if the user presses the “2” key of the numeric keypad 7, the personal data corresponding to the personal number “2” is stored in the personal number. It is displayed on the LCD 103 instead of the personal data “1”.
[0079]
At this time, as shown in FIG. 6C, the confirmed body weight value is kept displayed, and the personal data of the personal number “1” is switched to the personal data of the personal number “2”. Also at this time, when the registered weight value corresponding to the personal number “1” is held in the memory 35, the registered weight value is displayed below the confirmed weight value.
[0080]
Thereafter, for example, when the user presses the “1” key of the numeric keypad 7, personal data corresponding to the personal number “1” is displayed on the LCD 103 again. That is, the display content on the LCD 103 returns to the state shown in FIG. That is, if the user presses the “1” key and the “2” key of the numeric keypad 7 alternately, the display content of FIG. 6B and the display content of FIG. 6C are alternately displayed on the LCD 103. The
[0081]
In this way, even if the user reads personal data or selects personal data to be displayed on the LCD 103 in order to select personal data, the confirmed weight value remains displayed at the same position. maintain. Therefore, unlike the prior art, the displayed confirmed weight value (measured weight value) is not erased by calling the personal data. In addition, the registered weight value stored in the memory 35 is displayed in an identifiable manner below the confirmed weight value, so that the user can easily determine the confirmed weight value (measured weight value) and the registered weight value. Can be determined.
[0082]
Thereafter, the user operates the key input unit 104 to calculate the weight value used for calculating the health evaluation data (value related to body fat) between the determined weight value and the registered weight value simultaneously displayed on the LCD 103. Either can be selected. In this way, when the personal data is selected and the confirm button 12 is pressed, the personal data displayed at that time and the selected weight value are confirmed as values used for calculating the health evaluation data. Thereafter, the process proceeds to S020.
[0083]
In S020, a body fat measurement process is performed. That is, the user grips the grip portion 2 with the palm of the left hand in contact with the electrodes 105 and 107 from the front side of the body fat scale 30, and the palm of the right hand contacts the electrodes 106 and 108. Then, gripping the grip part 3 and extending both arms forward so as to be parallel to the horizontal plane takes a measurement posture of bioimpedance (see FIG. 7).
[0084]
Thereafter, when the user presses the measurement start switch 13, the bioelectrical impedance measuring unit 31 measures the potential difference between the electrodes 107 and 108, and the control unit 33 calculates the bioelectrical impedance value of the user from the measured potential difference. To do. Subsequently, the control unit 33 sets the body weight value (determined body weight value or registered body weight value) selected in S019, the measured bioelectrical impedance value, the height value as personal data, the age, and the sex to values relating to body fat. By substituting in the predetermined estimation formula, health evaluation data (for example, body fat percentage) is calculated.
[0085]
Thereafter, the control unit 33 displays the body fat percentage calculated in S020 on the LCD 103 (S021), and then returns the process to S001.
[0086]
As described above, according to the present embodiment, after weighing (after displaying the confirmed weight value), by calling or switching personal data, the confirmed weight value is not erased from the display content, The confirmed weight value and the registered weight value are displayed in an identifiable state. For this reason, the user can use either one for calculating the health evaluation data (value related to body fat) after clearly grasping the confirmed body weight value (measured body weight value) and the registered body weight value. However, when weight measurement is performed, a configuration in which the determined body weight value is compulsorily used for calculation of a value related to body fat may be employed.
[0087]
Therefore, it is possible to avoid the problem that the user cannot know whether the value related to the body fat is calculated using the measured body weight value or the registered body weight value, as in the past.
[0088]
In the present embodiment, the case where the display screen of the LCD 103 has a weight value display area of two weight values, that is, a confirmed weight value (measured weight value) and a registered weight value has been described. However, the LCD 103 displays one weight value display. In the case of having only a region, as shown in FIG. 8, if the determined weight value is not erased from the display content by switching personal data and is maintained as it is displayed, The registered weight value will not be displayed.
[0089]
For this reason, since the same weight value is always displayed at the same position on the personal data selection screen from the end of the weight measurement, the weight value used by the user to calculate the value related to body fat It is possible to clearly grasp that is a definite weight value. In this case, the determined body weight value is compulsorily used for calculating a value related to body fat.
[0090]
In the present embodiment, the determined weight value (measured weight value) and the registered weight value are displayed at the same time. However, the determined weight value and the registered weight value are alternately displayed by operating the key input unit 104. It is good also as a structure to be performed. At this time, the position where each weight value is displayed may be the same or different.
[0091]
In this embodiment, the example in which the weight scale 20 and the body fat scale 30 transmit and receive data by non-contact communication (infrared communication) has been described. However, the weight scale 20 and the body fat scale 30 are wired (power cable). And a data transmission line), and both may supply power and transmit / receive data via a wire.
[0092]
【The invention's effect】
According to the health management guideline advice device according to the present invention, after the user performs weight measurement and calling personal data, a value related to body fat is calculated using the bioelectrical impedance value, the weight value, and the personal data. In this case, the user can clearly discriminate the weight value used for calculating the value related to the body fat.
