The measured body information acquisition unit acquires the current weight of the measured body, and the calculation unit subtracts the value of the reference point from the current weight to indicate a change in fat mass It may be calculated as (hereinafter referred to as fat mass information). By making the change in body weight a change in fat mass, fat mass information indicating the change in fat mass can be obtained easily and with high accuracy.

  The reference point information acquisition unit includes actual fat mass information on the actual body fat mass measured by the reference device for measuring the fat mass of the measured body, and the measured body fat mass when the actual body fat mass is measured. Fat mass information calculated using body weight is obtained as the value of the reference point, and the calculation unit obtains a value obtained by subtracting the lean mass from the current body weight to indicate the current fat mass May be calculated as As a result, the fat amount to be reduced or increased in the current body weight is calculated using the information on the fat amount actually measured in the past (actual fat amount information) as a reference point. Fat mass information based on changes can be obtained.

  The actual fat mass information is the actual body fat mass measured by the reference device, the lean mass obtained by subtracting the actual fat mass from the body weight of the measured body when the actual body fat mass is measured, The body fat ratio indicating the ratio of the actual body fat mass in the body weight of the body to be measured when the actual body fat mass is measured, and the lean body mass in the body weight of the body to be measured when the actual body fat mass is measured It may also include at least one of the lean mass ratios indicating the proportion of the amount.

As a result, the amount of fat to be reduced or increased in the current weight is calculated using the standard weight corresponding to the body to be measured as a reference point, so it is easy to obtain fat amount information based on changes over time according to the individual. Can do.

  The reference measurement object information acquisition unit acquires the height and sex of the measurement object, and the reference point calculation unit uses a standard weight based on the height of the measurement object and a coefficient value based on gender. A standard lean mass at the standard weight (hereinafter, standard lean mass) is calculated as a reference point value, and the calculation unit calculates a value obtained by subtracting the standard lean mass from the current weight. You may calculate as fat mass information which shows fat mass.

  The reference measured body information acquisition unit is configured to measure actual fat mass information related to actual body fat mass measured by a reference device that measures the fat mass of the measured body, and the measured body when measuring the actual body fat mass. The reference point calculation unit receives the actual fat mass information and the body weight of the measured body when the actual body fat mass is measured in the reference measured body information acquisition unit. Instead of calculating the medically predetermined value as the reference point value, the body fat mass based on the actual fat mass information is calculated from the body weight of the measured body when the actual body fat mass is measured. The subtracted lean mass may be calculated as the value of the reference point, and the calculation unit may calculate a value obtained by subtracting the lean mass from the current weight as fat mass information indicating the current fat mass. .

  The health management device includes a storage unit that stores the current weight of the measurement object acquired by the measurement object information acquisition unit, and the reference point information acquisition unit stores the weight stored in the storage unit. You may acquire as a value of a reference point. Thereby, since the change from the past body weight of a to-be-measured body can be made into the change of fat mass, the fat mass information based on the change with time according to an individual can be obtained easily.

  The health management device includes a storage unit, an impedance acquisition unit that acquires the impedance of a predetermined body part of the body to be measured, and a lean mass calculation unit that calculates a lean mass based on the impedance and the weight at that time. The storage unit stores the calculated lean mass as the reference lean mass, and the reference point information acquisition unit uses the reference lean mass stored in the storage as a reference point value. The measured body information acquisition unit acquires the current weight, and the calculation unit calculates a value obtained by subtracting the reference lean mass from the current body weight to indicate the current fat mass. You may calculate as information. As a result, while using the lean mass obtained by measuring the impedance as a reference point, the measurement after the next time regards the change in body weight as the change in fat mass, and the fat mass information is calculated. Statistical elements are prevented from entering in measurement, and fat mass information based on changes over time according to individuals can be obtained easily.

  The health management device includes an impedance acquisition unit that acquires an impedance of a predetermined part of the body to be measured, and the calculation unit subtracts the value of the reference point from the current weight when calculating the fat mass information. The correction value may be multiplied by the correction coefficient based on the impedance.

  The health management device includes a physique level acquisition unit that acquires a physique level divided into a plurality according to the physique of the body to be measured, and the calculation unit calculates the fat mass information from the current weight.

<Outline of the invention>
First, an outline of the present invention will be described.

  In conventional body fat scales, body fat percentage is obtained by combining the bioimpedance data of the body to be measured (subject) obtained by measurement with the statistical data (average value) of body fat percentage derived from the body type. However, such a conventional body fat scale has the following three major problems.

  The first problem is that many statistical elements are included in the calculation of the body fat percentage as described above. In many cases, this is not a problem in transient measurement. However, when it is desired to know a change in fat mass over time, such as a diet, correct information cannot be obtained, which is a big problem.

Here, an example will be described in which a body under measurement having a body weight of 70 kg and a body fat percentage measured by an X-ray apparatus such as CT of 28% (that is, fat mass 19.6 kg) has been reduced by 10 kg. When the amount of fat in the body to be measured after weight reduction is measured with an X-ray device such as CT, the amount of fat often decreases by an amount substantially equal to the amount of change in body weight. That is, the amount of fat after weight loss is about 9.6 kg, and the body fat percentage at this time is 16%. However, since the conventional body fat scale does not reflect any information that the weight has been reduced from 70 kg to 60 kg, the body fat percentage is calculated based on the statistical value of the weight of 60 kg. As a result, in the conventional body fat scale, a display is made as if the body fat percentage after weight loss is 26.6% (the fat amount after weight loss is about 16 kg). Here, a measurement method (X-ray method) using an X-ray apparatus such as an X-ray CT apparatus is a method for obtaining fat mass from the X-ray absorption rate of the body of the measurement object, and includes statistical factors such as age and height. However, it has been established as a highly accurate measurement method.

  On the other hand, in the body fat scale using the conventional impedance method, it is understood that the dependence on the statistical element is high and the measurement of the fat mass is not accurate. In the first place, the impedance method can not directly measure fat that does not flow electricity (low water), but only indirectly estimates the amount of fat based on the lean mass of muscles with high water content. There is a limit to high-precision measurement. In addition, when the amount of moisture is changing temporarily, such as immediately after exercise or after bathing, the measured impedance value also changes greatly, so the results will vary greatly depending on the situation at the time of impedance measurement. There are many restrictions for accurate measurement.

  The second problem is that, in the measurement by the conventional body fat scale, the lean mass varies greatly due to the change in body weight. The composition of the human body can be broadly divided into two types: fat (amount) and non-fat lean (amount). In general adult men and women, most of the lean tissue is composed of invariant tissues such as organs, blood vessels, blood, and bones. Many. The lean tissue contains muscles (skeletal muscles) and body water, but in general life, the muscle composition rarely changes greatly (unless there is a sudden change in life). In addition, regarding body water, the circulating blood does not change following the change in body weight, except during abnormal times such as illness. Therefore, it is considered that the moisture does not change unless the muscle changes.

  As described above, in fact, the variation factor of the lean mass with respect to the change in body weight is overwhelmingly small in the same measured object. Nonetheless, the conventional body fat scale does not consider the past weight, so the fat mass is calculated with the fat mass at a certain point in the past significantly different from the current fat mass. The fat mass error is getting bigger.

  The third problem is that in the conventional body fat scale using the impedance method, the algorithm for incorporating statistical elements differs depending on the model or manufacturer, so the same body to be measured is measured with different body fat scales. However, a different result is output (an instrumental difference occurs for each body fat meter). This requires an algorithm in order to incorporate statistical elements, and there are various aspects of the algorithm, and there is a standard based on the weighing method for weight measurement, while measuring fat mass. The reason is that such a standard does not exist. As described above, body fat measurement using statistical elements is not accurate enough to follow changes over time, and it is considered that an algorithm that can be standardized as a standard cannot be established.

  Moreover, in such a body fat scale, since it is necessary to collect statistics in order to incorporate statistical elements in advance, it is necessary to change the algorithm itself incorporating statistical elements depending on gender and race. In particular, it is not easy to change the algorithm according to race, and it is not easy to produce a worldwide body fat scale using the impedance method. In addition, since a steep change in height is likely to occur in growing children and the like, and individual differences are large, statistical factors are difficult to apply, and the accuracy of body fat measurement for children cannot be increased.

  Inventors of the present invention have invented a health management device capable of realizing both “exclusion of statistical elements” and “no change in lean body mass” as a result of intensive studies based on the above three problems. I got the knowledge. That is, since the value obtained by subtracting the fixed lean mass from the body weight is the fat mass, the inventors of the present invention consider that “change in body weight = change in fat mass” is the most accurate calculation of fat mass. The knowledge that it becomes a formula was obtained. This is consistent with the fact that in the medical field, instruction is given to reduce weight in order to reduce body fat percentage.

Furthermore, it is common for conventional body fat scales to display “body fat percentage”, but in order to see changes in fat over time, it is convenient to see changes in fat mass, which is more In order to reduce the amount of fat, they have found that it is easy to set specific goals over time, such as caloric intake that can be taken per day.

  Based on such knowledge, the inventors of the present invention have invented the present invention. That is, a health management device according to an aspect of the present invention includes a reference point information acquisition unit that acquires a value of a reference point corresponding to a measurement object related to predetermined measurement object information, and a measurement object related to the measurement object information A measurement object information acquisition unit that acquires a current value of the measurement object, a calculation unit that calculates a health index based on a value obtained by subtracting the value of the reference point from the current value of the measurement object related to the measurement object information; It has. As a more specific configuration, the reference point information acquisition unit is based on a reference body weight (hereinafter referred to as reference weight) or a lean body mass (hereinafter referred to as reference lean body mass) obtained by subtracting the fat amount at that time from the reference body weight. The measured body information acquisition unit acquires the current body weight of the body to be measured, and the calculation unit subtracts the value of the reference point from the current body weight to change the fat mass. Is calculated as a health index (hereinafter referred to as fat mass information).

  According to the above configuration, the reference point corresponding to the measured value of the measured object itself is provided as a fixed value, and the health index is calculated based on the deviation from the value of the reference point. A health index can be provided. Furthermore, fat amount information indicating a change in fat mass can be obtained easily and with high accuracy by making the change in body weight a change in fat mass.

  At this time, since the calculated fat amount information does not require impedance measurement, there is no change in the fat amount information caused by impedance variation due to exercise, eating, drinking, bathing, or the like. Moreover, since the impedance is not directly related to the fat mass, such an estimation element can be eliminated. Furthermore, according to the above configuration, the fat mass information is calculated without using a statistical element, and the lean mass of the measurement object changes each time by changing the change in the body weight to the change in the fat mass. Therefore, a highly accurate health index according to the composition of the measurement object can be provided. In addition, since there is no need to use statistical elements, it is not necessary to prepare an algorithm for incorporating statistical elements, and as long as the change in weight is a change in fat mass, it is possible to use different models and between different manufacturers. It is possible to prevent a measurement difference (instrumental difference) in fat mass information from occurring. Further, by eliminating the need for statistical elements, it is possible to perform highly accurate measurement regardless of the race or age regardless of the object to be measured. In particular, according to this configuration, it is possible to measure fat mass with high accuracy even for a child in a growing period, which was difficult to measure in the past, although it is important to grasp the fat amount in the growing period. it can.

  Further, as a reference point, a medically predetermined value (for example, a standard weight as described later) based on predetermined measured body information such as height and weight, or an actual measured value of the measured body (for example, described later) The fat mass information is calculated using a measurement value obtained by an X-ray CT apparatus or the like. In this way, the concept of a reference point that has not been used in the conventional body fat scale is adopted, and since the fat mass information is calculated based only on the measured body information of the subject himself / herself, The fat amount information can be calculated with high accuracy.

  In addition, once the reference point is set, the health index is calculated simply by inputting (or measuring) the measured body information such as the current weight, so that the measurement can be performed with a simple operation, Measurement time can be shortened.

The memory | storage part 22 is comprised so that the said various information can be memorize | stored for every some subject. Thereby, the health index according to each of a plurality of subjects can be obtained with one device.

  The health management program 100 causes the control unit 20, which is a computer, to function so as to calculate the fat mass of the subject. Specifically, the information acquisition unit 21 of the control unit 20 includes a reference point information acquisition unit 211 that acquires a reference point value according to a subject related to predetermined measurement object information, and a subject related to measurement object information. It functions as the to-be-measured object information acquisition unit 212 that acquires the current value of. The calculator 23 calculates a health index based on a value obtained by subtracting the value of the reference point from the current value of the subject regarding the measured body information.

Obtained as a point value, the measured body information obtaining unit 212 obtains the current weight of the subject. Further, the calculation unit 23 functions as a fat mass information calculation unit 231 that calculates a value obtained by subtracting the value of the reference point from the current weight as a health index (hereinafter, fat mass information) indicating a change in fat mass.

  The reference weight acquired by the measured body information acquiring unit 212 may be a weight value measured by the weight measuring unit 12 or a weight value input from the operation unit 13 separately. When the reference lean mass is acquired by the measured body information acquisition unit 212, the weight value is input from the weight measurement unit 12 or the operation unit 13, and the reference value is input from the operation unit 13 or the impedance measurement unit 16.

  Hereinafter, a plurality of modes for performing calculation of fat mass information using the value of the reference point will be described.

<Aspect using the value based on the actual fat mass information obtained from the reference device as the reference point>

Calculated. Such calculation of lean mass may be performed by the reference point calculation unit 232 or may be performed by the reference device 30 side. When the lean mass is output from the reference device 30, the reference point information acquisition unit 211 may directly acquire the lean mass.

  Further, the actual fat mass information acquired by the reference measured body information acquisition unit 213 is not limited to the actual body fat mass and the lean mass measured by the reference device 30 as described above, and the actual fat mass is measured. Body fat percentage indicating the ratio of the body fat amount to the body weight of the subject when measured, or the lean body percentage indicating the ratio of the lean body mass to the subject weight when measuring the actual body fat mass Good. When the reference measured body information acquisition unit 213 acquires these values, the reference point calculation unit 232 uses the weight at the time of measurement by the reference device 30 from these values to calculate the lean mass (the reference point value ( (Fixed value). Thereby, in this aspect, the lean mass of the subject is calculated only from the measured value of the subject himself / herself.

The fat amount calculating unit 231 calculates a value obtained by subtracting the lean body mass from the current weight as fat amount information indicating the current fat amount. That is, since the lean body mass is less changed due to changes in body weight, the current value is obtained by subtracting the lean body mass from the current body weight with a fixed value (lean body mass measured by the reference device 30 = current lean body mass). Fat mass is calculated. As a result, the fat amount to be reduced or increased in the current body weight is calculated using the information on the fat amount actually measured in the past (actual fat amount information) as a reference point. Fat mass information based on changes can be obtained. Further, according to this aspect, since the lean mass of the body to be measured is calculated only by the measurement value of the subject himself, it is possible to obtain fat mass information with much higher accuracy than measurement using a statistical element. it can. In addition, once information on the actual fat mass is acquired using the reference device 30 once in the past, the reference device 30 is used in the subsequent measurement of the body fat mass without using the reference device 30. A measurement result substantially equivalent to the case can be obtained.

  The health management device 10 according to the present embodiment is based on an aspect in which a medically predetermined value (for example, standard weight or standard lean mass), which will be described later, is used as a reference point, and actual fat mass information obtained from the reference device 30. It is possible to use in combination with an aspect in which the value is used as a reference point. However, if the fat amount information can be calculated in any aspect, the reference point information acquisition unit 211 preferentially uses a value based on the actual fat amount information obtained from the reference device 30 as a reference point. Configured as follows. As a result, when information about the fat mass actually measured in the past (actual fat mass information) is known, the actual fat mass information is preferentially used as a reference point (an element having a higher ratio of measurement values by the person). Since the amount of fat to be reduced or increased in the current body weight is calculated, fat amount information based on changes over time according to the individual can be obtained easily.

<Aspect using medically predetermined value based on reference object information as reference point>
When the reference measurement object information acquisition unit 213 acquires reference measurement object information such as height and weight, the reference point calculation unit 232 uses a medically predetermined value as a reference point based on the reference measurement object information. As the value of. For example, the reference measured body information acquisition unit 213 acquires the height of the subject, and the reference point calculation unit 232 calculates the standard weight of the subject from the height of the subject. The standard weight Wi (kg) is given by Wi = L ² × 22, where the height is L (m). The standard weight indicates the weight when the height L is BMI 22. A BMI of 22 has been medically advocated as being the healthiest for humans. Thus, the standard weight is a value that is uniquely determined medically based on the height. The reference point calculation unit 232 stores the obtained standard weight Wi value in the storage unit 22 as a reference point value.

  Further, the measured body information acquisition unit 212 acquires the current weight of the subject based on the input from the weight measurement unit 12 or the operation unit 13. When calculating the fat mass information, the reference point information acquisition unit 211 acquires the standard weight stored in the storage unit 22 and sends it to the fat mass calculation unit 231 together with the current weight acquired by the measured body information acquisition unit 212. introduce. The fat amount calculation unit 231 calculates a change in the current weight with respect to the standard weight (fixed value) as fat amount information. Specifically, the fat mass information at this time indicates the fat mass to be increased or decreased to obtain the standard weight.

  As a result, the amount of fat to be reduced or increased in the current body weight is calculated using the standard weight that is medically predetermined according to the individual as a reference point, so the amount of fat based on changes over time according to the individual is simple. Information can be obtained. In particular, even for a growing child with a large change in height, if the height changes, the standard weight also changes accordingly, so even if there is a sudden change in the height of the subject, it is highly accurate depending on the individual. Fat mass information can be calculated. Therefore, it is possible to provide effective fat amount information even for a growing child, which has been considered difficult in the past. In addition, when it is predicted that the change in height is large as described above, it is preferable to obtain height information for each measurement, calculate the standard weight for each measurement, and update the reference value with the standard weight. .

In addition, for example, the reference measurement object information acquisition unit 213 acquires gender in addition to the subject's height, and the reference point calculation unit 232 uses a standard weight based on the subject's height and a coefficient value based on gender. Are used to calculate the standard lean mass (hereinafter, standard lean mass) at the standard weight as the reference point value. The standard lean mass Fi (kg) can be expressed as Fi = Wi × (1−0.28) in the case of a male and Fi = Wi × (1−0.33) in the case of a female using the standard weight. I can express. Thus, the standard lean mass is a value that is medically and uniquely determined in advance based on height and sex. The reference point calculation unit 232 stores the obtained value of the standard lean mass Fi in the storage unit 22 as the reference point value. The measured object information acquisition unit 212 acquires the current weight of the subject as in the case of using the standard weight.

  The fat mass calculation unit 231 calculates a value obtained by subtracting the standard lean mass from the acquired current weight as fat mass information indicating the current fat mass. That is, since the standard lean mass is less changed due to changes in body weight, the current fat mass is determined by subtracting the standard lean mass from the current weight with a fixed value (standard lean mass = current lean mass). Calculated. This also calculates the amount of fat to be reduced or increased in the current body weight using the standard lean mass according to the individual as a reference point, so that it is easy to obtain fat mass information based on changes over time according to the individual. be able to.

<Mode using previously acquired weight as reference point>
In the health management device 10 of the present embodiment, it is also possible to use the previously acquired weight as the reference point value. In this case, when the measured body information acquisition unit 212 acquires the weight, the storage unit 22 stores the weight. In the subsequent measurement of fat mass information, the measured body information acquisition unit 212 acquires the current weight, and the reference point information acquisition unit 211 uses the weight stored in the storage unit 22 as a reference point value ( Get as a fixed value). The fat amount calculation unit 231 subtracts the weight stored in the storage unit 22 from the current body weight, and thereby changes the weight from the time of measurement of the weight stored in the storage unit 22 to indicate the change in the fat amount. Calculate as Thereby, since the change from the past body weight of the subject can be set as a change in fat mass, fat mass information based on a change with time according to the individual can be obtained easily.

<Aspect using a value based on fat mass information obtained from impedance as a reference point>
In the health management device 10 of the present embodiment, the lean mass based on the impedance of a predetermined body part of the subject can be used as the reference point value. In this case, the impedance acquisition unit 214 acquires the impedance of the subject from the impedance measurement unit 16 or the operation unit 13, and the lean mass calculation unit 233 uses the impedance method based on the acquired impedance and the weight at that time. The lean mass (reference lean mass) is calculated. The weight at the time of impedance measurement may be measured by the weight measurement unit 12 or may be input from the operation unit 13.

  The reference lean mass calculated by the lean mass calculator 233 is stored in the storage unit 22 as a reference point value. In the subsequent measurement of fat mass information, the measured body information acquisition unit 212 acquires the current body weight, and the reference point information acquisition unit 211 stores the reference lean body mass stored in the storage unit 22 from the current body weight. A value obtained by subtracting the amount is calculated as fat amount information indicating the current fat amount. As a result, while using the lean mass obtained by measuring the impedance as a reference point, the measurement after the next time regards the change in body weight as the change in fat mass, and the fat mass information is calculated. Statistical elements are prevented from entering in measurement, and fat mass information based on changes over time according to individuals can be obtained easily.

<Correction mode>
In each of the above-described aspects, the aspect in which the fat mass calculation unit 231 outputs the difference between the reference point and the measured body information such as the current weight as the fat mass information as it is is mainly described. The fat amount information may be calculated by multiplying the difference by a predetermined correction coefficient.

  In particular, when the standard weight and the standard lean mass are used, the actual lean mass of the subject may deviate from the standard lean mass as the subject's weight deviates from the standard weight. This is thought to be due to the fact that when the body weight increases from the standard weight, the proportion of muscle mass increases to support the body weight. Thus, individual differences in lean mass can be corrected by correcting fat mass information as follows.

  For example, the fat mass information calculation unit 231 is configured to multiply the value obtained by subtracting the value of the reference point from the current weight by a correction coefficient based on the impedance acquired by the impedance acquisition unit 214 when calculating the fat mass information. The In this case, a group is divided into a plurality of groups (for example, groups of about 3 to 5) according to the impedance value, and correction coefficients (for example, 0.8 / 0.9 / 1.0 / 1.1 / 1) are grouped for each group. .2 etc.). Then, the fat mass information calculation unit 231 calculates a correction coefficient corresponding to the group to which the impedance acquired by the impedance acquisition unit 214 belongs to the value obtained by calculating the difference between the reference point and the measured body information using each aspect. The multiplied value is output as fat mass information.

  As a result, it is possible to correct the rate of change in fat mass due to changes in body weight and individual differences between subjects with respect to the standard lean mass using impedance values. Fat mass information can be obtained. Further, the impedance value is used not to know the fat mass itself but to know the general tendency of the subject regarding the original muscle condition (that is, the ratio of the lean mass). For this reason, the accuracy of impedance measurement itself does not need to be high, and high-accuracy fat mass information can be easily calculated without using statistical elements.

  Further, for example, when calculating the fat mass information, the fat mass information calculation unit 231 multiplies the value obtained by subtracting the value of the reference point from the current weight by a coefficient corresponding to the physique level acquired by the physique level acquisition unit 215. Configured as follows. In this case, a coefficient (for example, 0.8 / 0.9 / 1.0 / 1.1 / 1.2) is assigned according to a physique level divided into a plurality (for example, a group of about 3 to 5). The physique level is classified according to, for example, the rate of exercise or the rate of muscle training, and is input from the operation unit 13 by the subject's self-report. And the fat mass information calculation part 231 multiplied the coefficient according to the physique level acquired by the physique level acquisition part 215 to the value which calculated the difference of a reference point and to-be-measured body information using each said aspect. The value is output as fat mass information. Also by this, since the rate of change in fat mass due to change in body weight can be corrected according to the physique level, it is possible to obtain fat mass information based on changes over time according to the individual.

  The mode of correction is not limited to the above. For example, the circumference of a predetermined part of the subject (for example, waist, thigh diameter, etc. or sebum thickness of the predetermined part (measured value by a so-called caliper method) is used. It is good also as correcting.

<Future value prediction mode>
The health management device 10 of the present embodiment can also calculate a specific target value that leads to improvement of lifestyle habits based on the fat amount information calculated according to the above aspects. For example, the weight loss information acquisition unit 216 acquires weight loss information related to intake or consumption of calories per predetermined period based on the fat amount information. The weight loss information is input from the operation unit 13. The weight loss information is, for example, a target value for the amount of calorie reduction per day.

The predicted value calculation unit 234 calculates at least one of body weight and fat mass predicted after a predetermined period of time based on the weight loss information and the fat mass information. At this time, the predicted value calculation unit 234 displays the fat amount to be reduced (excess fat amount) based on the fat amount information calculated by the fat amount calculation unit 231 on the display unit 14 and sets the excess fat amount to 0. The amount of calories to be consumed in order to be displayed can be displayed. When the fat amount information is equal to or less than the reference point value (when the excess fat amount is negative), the fat amount to be reduced may be displayed as 0, or may be displayed negatively (or displayed as the fat amount to be increased). May be. The subject or the operator inputs the weight reduction information such as the target value of the calorie reduction amount per day and the weight reduction period from the operation unit 13 with reference to these values displayed on the display unit 14.

  When the weight loss information acquisition unit 216 acquires the input weight loss information, the predicted value calculation unit 234 calculates the predicted body weight and the predicted fat amount after the weight loss period has elapsed, and displays them on the display unit 14. For example, when the subject's weight is 78.40 kg, fat amount is 22.26 kg, excess fat amount is 9.32 kg, calorie amount to be consumed is 67122 kcal, the target value of daily calorie reduction is 300 kcal, and the weight loss period is 6 When the month is entered, the weight after 6 months is displayed as 70.7 kg, the fat mass after 6 months is 14.56 kg, and the predicted decrease in body weight and fat mass is 7.7 kg. Thereby, the subject can examine the amount of calorie reduction per day and the weight loss period by comparing the excess fat amount with the predicted decrease in body weight and fat amount. Thus, since prediction after the lapse of a predetermined period can be performed based on fat mass information and assumed weight loss information, it is possible to easily provide a policy regarding daily intake or consumption of calories according to the individual. it can.

<Control flow>
Below, the flow of control of the health management apparatus 10 provided with each said aspect is illustrated. The flowchart shown in FIG. 3 shows an outline from when the health management apparatus 10 is turned on until the power is turned off. First, after the power is turned on, a registration number selection screen is displayed on the display unit 14 (step S1). When the subject has been registered in the past, the registration number is selected and input. When the subject is new, the registration number to be newly registered is selected and input. The control unit 20 determines whether the selected registration number is new (whether past data exists in the registration number) (step S2).

  When the selected registration number is new (Yes in step S2), the control unit 20 causes the display unit 14 to display an input screen for reference object information, and the reference object information such as height, sex, and age is displayed. Is input (step S3). At this time, if necessary, a physique level may be input. The control unit 20 stores each value of the inputted reference measured object information in the storage unit 22 in association with the registration number. On the other hand, when data already exists in the selected registration number (No in step S2), the control unit 20 causes the display unit 14 to display an inquiry screen as to whether to update (change) the registered data ( Step S4). When updating the registered data (Yes in step S4), the control unit 20 displays the input screen for the reference measured object information described above (step S3). When the registered data is not updated (No in step S4), the data of the reference measured object information registered in the registration number is read from the storage unit 22.

  Thereafter, the control unit 20 displays an inquiry screen on how to set the reference point on the display unit 14 (step S5). Specifically, whether the control unit 20 uses the actual fat amount information measured by the reference device 30, uses a medically predetermined value based on the reference measured body information, or uses a past weight Then, a screen for inquiring whether to use the reference lean mass measured by the impedance method is displayed on the display unit 14. When there is an input for selecting one of these and input of information on a corresponding reference point if necessary, the control unit 20 performs processing for acquiring the corresponding reference (step S6). In addition, when the actual fat amount information by the reference device 30 already exists in the registration information stored in the storage unit 22 and another aspect is selected, the actual fat amount information is recommended. It is good also as performing display and using actual fat amount information compulsorily. Alternatively, in the case where the actual fat amount information by the reference device 30 already exists in the registration information, the actual fat amount information may be automatically selected before the inquiry screen.

  Thereafter, the control unit 20 functions as the measured object information acquiring unit 212 and acquires measured object information such as the current weight (step S7). And the control part 20 functions as the fat mass information calculation part 231, and calculates fat mass information based on the value of a reference point, and to-be-measured body information (step S8). In addition, when correcting by an impedance or a physique level, a correction process is performed by this step. The control unit 20 displays the calculated fat amount information on the display unit 14 (step S9).

  The fat amount information displayed on the display unit 14 may be displayed not only in the fat amount itself but also in a form such as a lean body mass, a body fat percentage, and an excess fat amount, and the display may be switchable. Further, the current weight, reference point value, reference measured body information, and other health indicators such as BMI may be displayed on the fat mass information display screen.

  On the fat mass information display screen, a predetermined operation from the operation unit 14 for starting the above-described future value prediction calculation is received (step S10). When the future value prediction calculation is performed (Yes in step S10), the control unit 20 functions as the weight loss information acquisition unit 216 and waits for the input of the weight loss information and the weight loss period. Obtain (step S11). The control unit 20 functions as the predicted value calculation unit 234, and calculates at least one of body weight and fat mass predicted after a predetermined weight loss period based on the weight loss information and the fat mass information (step S12). The control unit 20 displays at least one of the calculated predicted body weight and fat mass on the display unit 14 (step S14).
