Description

  The present invention relates to a metabolic evaluation device, a metabolic evaluation method, and a metabolic evaluation program.

  It is known that there is a correlation between the concentration of acetone in exhaled air and the amount of lipid consumed. For example, Patent Document 1 measures the concentration of acetone in exhaled air and responds to the analysis result of the measured acetone concentration. Thus, a technique for determining a timing suitable for taking a meal or a timing suitable for performing exercise is disclosed.

International Publication No. 2013/038959 Pamphlet

  One of the main concerns of people who exercise or receive treatments that increase metabolism (such as massage) is diet (decrease in weight and body fat), but weight and body fat are long-term lives. Since it changes according to the accumulation of behavior, it is difficult for a clear change in weight and body fat to appear in short-term exercise or treatment. For this reason, there is a need to understand the degree of effects of exercise and treatment, etc. by grasping the state of metabolism that changes even though it is small even with short-term exercise or treatment other than body weight and body fat percentage. .

  However, carbohydrates ingested by meals are consumed preferentially over lipids, and the rate of lipid consumption in human energy consumption depends greatly on how much carbohydrates ingested by meals remain in the body. For this reason, even if the lipid consumption is known from the concentration of acetone in the exhaled breath, the state of metabolism, for example, whether carbohydrate consumption or lipid consumption is dominant, currently carbohydrate consumption is dominant. It is not possible to grasp whether or not lipid consumption is in full swing soon.

  The amount of residual carbohydrate can be determined by collecting blood and measuring the blood glucose level. However, the measurement of the blood glucose level that requires blood sampling, for example, to understand changes in the metabolic state before and after exercise or treatment, etc. Like this, it is not suitable when it is desired to check the metabolic state at a high frequency.

  The present invention has been made in consideration of the above facts, and obtains a metabolic evaluation apparatus, a metabolic evaluation method, and a metabolic evaluation program capable of evaluating a metabolic state including residual carbohydrates without requiring blood collection or the like.

And outputting at least one of the calculated carbohydrate residual and lipid consumption of the user, and evaluation information for evaluating the metabolic state of the user according to the calculated residual carbohydrate and lipid consumption of the user. To do.

  Further, the present invention provides a first measured ketone body concentration obtained by measuring a ketone body discharged from a user's body, and discharged from the user's body after a predetermined time or more after the measurement timing of the first measured ketone body concentration. And a second measured ketone body concentration obtained by measuring the obtained ketone body. Then, it is discharged from the human body by the first ketone body concentration discharged from the human body at a predetermined timing or by a physical quantity having a correlation with the first ketone body concentration and after a predetermined time or more of the predetermined timing.

  Next, a stationary metabolic evaluation device 66 as another example of the metabolic evaluation device 10 will be described with reference to FIGS. The stationary metabolic evaluation device 66 has a function of measuring physical information including a user's physique (for example, body weight) and body composition (for example, at least one of body fat, subcutaneous fat, visceral fat, muscle mass, body water, etc.). Is a device in which a function as the metabolic evaluation device 10 is incorporated, and is installed in a home, a hospital, a sports gym, or the like. Hereinafter, as an example of the stationary metabolic evaluation apparatus 66, a configuration suitable for installation in a facility (such as a sports gym) used by various users will be described.

  As shown in FIG. 4, the stationary metabolic evaluation apparatus 66 is electrically connected to the apparatus main body 68, and is separable from the apparatus main body 68 through the apparatus main body 68 (I / F (InterFace) unit 68 C described later) and the cable 70.

The measurement unit 72 includes an acetone measurement sensor 80 (see FIG. 5), and an acetone concentration measurement unit 82 having the same configuration as the acetone concentration measurement unit 28 of the portable metabolic evaluation device 24 is provided.

  As shown in FIG. 5, the stationary metabolic evaluation apparatus 66 includes a CPU (Central Processing Unit) 84, a memory 86, a nonvolatile storage unit 88, the aforementioned body information measurement unit 74, a display unit 76, an input unit 78, and acetone. A measurement sensor 80, a user detection unit 90, and a communication unit 92 are included, and these are connected to each other via a bus 89.

  The storage unit 88 stores a metabolic evaluation program 48, a metabolic state calculation table 50, a metabolic evaluation information table 52, and a reward / homework information table 54, and is an example of the storage unit 20 shown in FIG. The CPU 84 functions as the acquisition unit 12, the calculation unit 14, and the output unit 16 illustrated in FIG. 1 by reading the metabolic evaluation program 48 from the storage unit 88 into the memory 86 and executing it. Other information stored in the storage unit 88 will be described later.

  The user detection unit 90 detects a user who is using the stationary metabolic evaluation device 66. When the stationary metabolic evaluation device 66 is installed in a facility used by various users, such as a gym, for example, the user detection unit 90 may be, for example, an IC card possessed by the current user or The current user can be detected by obtaining the user ID from the IC tag. When the stationary metabolic evaluation device 66 is used in an environment where the number of users is limited, such as at home, for example, the user detection unit 90 selects the current one from among buttons corresponding to individual users. The current user can be detected by causing the user to select a button corresponding to the user.

  The communication unit 92 can communicate with an external device connected to the network 56 by wireless communication or wired communication. FIG. 5 shows a user information server 60 as an example of an external device. The user information server 60 is a server that provides information on the user on which the stationary metabolic evaluation device 66 is installed, and a user information table 64 is stored in the storage unit 62 of the user information server 60. The user information table 64 stores information on individual users in association with user IDs of individual users.

  The individual user information stored in the user information table 64 includes attribute information such as the user's age, sex, and height, physical information measured in the past by the stationary metabolic evaluation device 66, and stationary metabolic information. Each information of the metabolic state output in the past by the evaluation device 66 is included. In addition, when the stationary metabolic evaluation apparatus 66 is installed in a sports gym, the information on each individual user includes, for example, a user information collected by the user information server 60 from each training machine in the sports gym. Information such as time and contents of use of individual training machines may be included.

  As described above, the stationary metabolic evaluation apparatus 66 also includes a metabolism unit including the measurement unit 18 (an acetone concentration measurement unit 82 as an example) and the storage unit 20 (an example storage unit 42) illustrated in FIG. 1 is an example of an evaluation device 10.

  Next, the operation of this embodiment will be described. A person's remaining sugar amount x [kcal] or a remaining sugar ratio X [%] (a ratio of a consumed sugar amount to a person's consumed energy (non-protein combustion)) is a sugar intake amount α [ kcal] (or γ [g]), energy consumption per hour β [kcal / h], elapsed time t [h] after intake of carbohydrates, and protein consumption energy. Further, the energy consumption β per person varies according to the person's basal metabolism R [kcal / 24h] and the activity level, and the basal metabolism R varies according to the person's physique and body composition. .

  On the other hand, the inventors of the present application collected data by measuring changes in the residual carbohydrate amount x and the acetone concentration a [ppb] after intake of carbohydrates for a large number of investigators. As a result, there is a correlation between the residual sugar amount x and the acetone concentration a. In particular, in the data narrowing down at least one of the carbohydrate intake amount α and the energy consumption β per hour, the residual carbohydrate amount x and The knowledge that the correlation with the acetone concentration a becomes stronger was obtained. The protein energy consumption can be regarded as constant.

  FIG. 6 shows that when the protein consumption energy is regarded as constant and the carbohydrate intake α and the energy consumption β per hour are narrowed down to a certain range, the acetone concentration a, the carbohydrate residual rate X [%], and the lipid consumption rate An example of the relationship with Y [%] (ratio of lipid consumption in human energy consumption (non-protein combustion)) is shown. The residual carbohydrate rate X is obtained from the residual carbohydrate amount x and the lipid consumption amount y [kcal] by the following equation (1), and the lipid consumption rate Y is obtained by the following equation (2).

X = x / (x + y) × 100 [%] (1)
Y = y / (x + y) × 100 [%] (2)

  The state of metabolism is the state corresponding to the position in the left region (range where the acetone concentration a is relatively low) in the relationship shown in FIG. As the time has elapsed since carbohydrate intake, the position in the relationship shown in FIG. 6 moves to the right side, the acetone concentration a and lipid consumption increase, and carbohydrate consumption decreases.

  Based on the above-described knowledge, in the present embodiment, the metabolic state calculation table 50 shown as an example in FIG. 7 is obtained in advance as information defining the relationship between the acetone concentration and the carbohydrate residue from the previous data, and the obtained metabolism. The state calculation table 50 is stored in the storage unit 42 of the portable metabolism evaluation device 24 and the storage unit 88 of the stationary metabolism evaluation device 66. As shown in FIG. 7, the metabolic state calculation table 50 shows the relationship between the acetone concentration a and the elapsed time t after carbohydrate intake for each carbohydrate intake α (or γ [g]) and per time. It is a table defined for each energy consumption β.

In FIG. 7, carbohydrate intake α ₁ (γ ₁ ),..., Consumed energy β ₁ , β ₂ ,..., Elapsed time after carbohydrate intake t _{1 to} t ₅ and acetone concentration a _{1 to} a Reference numeral ₅ represents a representative value within a predetermined numerical range. FIG. 7 shows, as an example, the relationship between the acetone concentration a and the elapsed time t after the carbohydrate intake when the sugar intake α and the energy consumption β per hour are within a certain numerical range. The number of numerical ranges may be 4 or less or 6 or more. Similarly, the number of numerical ranges of the carbohydrate intake α (γ ₁ ) and the energy consumption β per hour can be selected as appropriate.

  By using the metabolic state calculation table 50, the elapsed time t after carbohydrate intake can be obtained from the acetone concentration a when the carbohydrate intake α (or γ) and the consumed energy β per hour are within a certain numerical range, respectively. . Then, the remaining carbohydrate amount x can be calculated by substituting the carbohydrate intake amount α, the energy consumption β per hour, and the obtained elapsed time t after the intake of the carbohydrate into the following equation (3).

x = α− (β × t) [kcal] (3)

  The metabolic state calculation table 50 shown in FIG. 7 also defines the relationship between the acetone concentration a and the lipid consumption y. The lipid consumption y is uniquely determined from the acetone concentration a by using a known technique. Therefore, it is not essential to define the relationship between the acetone concentration a and the lipid consumption y in the metabolic state calculation table 50.

  As shown in FIG. 8, in the metabolic evaluation information table 52, a plurality of metabolic evaluation information including a message for evaluating a user's metabolic state is registered in association with selection conditions for individual metabolic evaluation information. In the present embodiment, when the acetone concentration is measured again within a predetermined time range after the previous measurement of the acetone concentration, for example, when the acetone concentration is measured before exercise and the acetone concentration is measured again after exercise, a plurality of Any of the metabolic evaluation information is displayed on the display unit 30 or the display unit 76 in the form of a message or the like.

As an example, the evaluation information selection condition of the metabolic evaluation information table 52 shown in FIG. 8 divides the previous acetone concentration a_b [ppb] into four numerical ranges, and subdivides each numerical range into three stages. . Specifically, for two numerical ranges where the previous acetone concentration a_b is relatively low (“a_b <a _A ” and “a _A ≦ a_b <a _B ”), the amount of change in the acetone concentration (previous acetone concentration a_b−current time). For two numerical ranges (“a _B ≦ a_b <a _C ” and “a_b ≧ a _C ”) in which the previous acetone concentration a_b is relatively high, It is subdivided according to the density a_n [ppb].

  As described above, as the evaluation information selection condition, the amount of change in the acetone concentration and the current acetone concentration a_n are selectively used according to the level of the previous acetone concentration a_b. The previous acetone concentration a_b is relatively low. In other words, when the lipid consumption is relatively low, the amount of change in acetone concentration, that is, whether the lipid consumption has increased, and the degree of increase when the lipid consumption has increased, are the main concerns of the user. On the other hand, if the previous acetone concentration a_b is relatively high, that is, if the lipid consumption is originally relatively high, whether or not the current acetone concentration a_n is not excessive, that is, there is no risk of depletion of carbohydrates. This is because it is necessary to evaluate whether or not and notify if necessary.

  As shown in FIG. 9, the reward / homework information table 54 divides the remaining carbohydrate amount x into a plurality of numerical ranges, and the food that the user may take as a snack (reward) for each numerical range. And the homework information indicating the behavior that the user recommends to adopt as a lifestyle in the future are registered in association with each other.

  Next, with reference to FIG. 10, the metabolic evaluation process performed by the metabolic evaluation apparatus 10 (the portable metabolic evaluation apparatus 24 or the stationary metabolic evaluation apparatus 66) will be described. The metabolic evaluation process is performed by executing the metabolic evaluation program 48 triggered by the user instructing measurement of acetone concentration (or evaluation of metabolic state).

  In step 100 of the metabolic evaluation process, the acquisition unit 12 requests the user to blow the breath to the measurement unit 18, for example, by displaying a predetermined message on the display unit 30 or the display unit 76, and the user. The measurement unit 18 measures the acetone concentration a in the exhaled breath, and acquires the acetone concentration a measured by the measurement unit 18. In the next step 102, the metabolic evaluation apparatus 10 performs a metabolic state calculation process.

  As shown in FIG. 11, in step 130 of the metabolic state calculation process, the acquisition unit 12 determines whether or not the user's carbohydrate intake α can be acquired. The user's carbohydrate intake α means the carbohydrate intake in the user's most recent meal. In this embodiment, whether or not the user inputs the carbohydrate intake α every time the metabolic state is evaluated. This is set in advance.

  When the setting related to the carbohydrate intake α is a setting in which the user inputs the carbohydrate intake α every time the metabolic state is evaluated, the determination in step 130 is affirmed and the process proceeds to step 132. The acquisition unit 12 requests the user to input a carbohydrate intake α by, for example, displaying a predetermined message on the display unit 30 or the display unit 76, and the carbohydrate intake input by the user. Acquire α.

  The input of the carbohydrate intake α by the user may be a numerical value of the carbohydrate intake α, but the amount of meal in the user's most recent meal is, for example, “small” or “normal”. When divided into a plurality of levels (ranges) such as “many”, the user may be allowed to select which level corresponds. In this case, the acquisition unit 12 may acquire the carbohydrate intake α corresponding to the selected level. In addition, the carbohydrate intake α corresponding to each level may be fixedly determined, or according to user attribute information (eg, at least one of gender, age, height, etc.) and physical information. It may be changed.

  On the other hand, if the setting related to the carbohydrate intake α is not a setting for the user to input the carbohydrate intake α every time the metabolic state is evaluated, the determination in step 130 is denied and the process proceeds to step 134. The acquisition unit 12 reads the default value of the carbohydrate intake α stored in advance in the storage unit 20. The default value of the carbohydrate intake α may also be fixedly determined, or may be changed according to user attribute information or the like.

  In the next step 136, the acquisition unit 12 determines whether it is possible to acquire physical information such as the user's physique and body composition. If the determination in step 136 is affirmative, the process proceeds to step 138. In step 138, the acquisition unit 12 acquires physical information such as the user's physique and body composition. In step 140, the calculation unit 14 calculates the basal metabolic rate R of the user according to a predetermined calculation formula based on the physical information such as the user's physique and body composition acquired by the acquisition unit 12.

  The determination in step 136 is unconditionally determined in the case of the stationary metabolic evaluation apparatus 66. In step 138, the acquisition unit 12 receives the user's physical information from the user information server 60, or Obtained by measuring the physical information of the user by the physical information measuring unit 74.

  The portable metabolic evaluation device 24 can also allow the user to input the physical information of the user, and the setting related to the physical information is a setting for the user to input the physical information every time the metabolic state is evaluated. In this case, the determination in step 136 is affirmed, and the process proceeds to step 138. In step 138, the acquisition unit 12 displays the predetermined message on the display unit 30, for example, to display the physical information to the user. Requests input and obtains physical information input by the user.

  On the other hand, in the portable metabolism evaluation device 24, when the setting related to physical information is not the setting for the user to input physical information every time the metabolic state is evaluated, the determination in step 136 is denied and the process proceeds to step 142. In step 142, the acquisition unit 12 reads a default value of the basal metabolism R stored in advance in the storage unit 20. The default value of the basal metabolic rate R may also be fixedly determined, or may be changed according to user attribute information or the like.

  Also, instead of reading the default value of basal metabolism R in step 142, the default value of physical information is read, and the basal metabolic rate R of the user is calculated according to a predetermined arithmetic expression based on the read default value of physical information. You may make it calculate. The default value of the physical information may be fixedly determined or may be changed according to the attribute information of the user.

  In the next step 144, the acquisition unit 12 determines whether or not the activity level of the user can be acquired. In this embodiment, each time the metabolic state is evaluated, whether or not the user inputs an activity level is set in advance. In the case where the user inputs the activity level every time the metabolic state is evaluated, the determination in step 144 is affirmed and the process proceeds to step 146. In step 146, the acquisition unit 12 displays, for example, the display unit 30 or the display unit. By requesting the user to input an activity level by displaying a predetermined message on the unit 76, the activity level input by the user is acquired.

  For example, when an activity level is divided into a plurality of levels (ranges) such as “low”, “normal”, and “high”, the user can specify which level corresponds to the user. Can be selected. In addition, if the metabolic evaluation apparatus 10 is installed in a sports gym and is a stationary metabolic evaluation apparatus 66 that allows a user to collect information such as time and contents of use of individual training machines from the user information server 60. The acquisition unit 12 can also collect the information from the user information server 60 and determine the activity level of the user based on the collected information.

  On the other hand, if the user does not set the activity level every time the metabolic state is evaluated, the determination in step 146 is denied and the process proceeds to step 148. The stored default value of the activity level (for example, rest to desk work level) is read. Further, the metabolic evaluation apparatus 10 is portable and may be configured to measure at least one of parameters correlated with the activity level of the user, for example, the user's “step count”, “walking time”, “energy consumed by activity”, and the like. For example, the measurement result of the parameter may be acquired, and the activity level of the user may be determined based on the acquired measurement result of the parameter.

  In step 150, the calculation unit 14 determines the user's basal metabolic rate R obtained in step 140 or 142 and the user's activity level obtained in step 146 or step 148 based on the user's activity level. Calculate the energy consumption β per hour. The calculation method of the energy consumption for each activity level is known, and the user's energy consumption per hour β is calculated for each activity level calculated by converting the user's basic metabolic rate R into the user's metabolic rate per hour. It can be calculated by adding the energy consumption.

  In the next step 152, the calculation unit 14 acquires the user's carbohydrate intake α obtained in step 132 or 134, the user's consumed energy β calculated in step 150, and the previous step 100. The elapsed time t after the user's carbohydrate intake corresponding to the acetone concentration a is obtained from the metabolic state calculation table 50. In step 154, the calculation unit 14 sets the user's carbohydrate intake α, the user's consumed energy β per hour, and the user's elapsed time t after the carbohydrate intake obtained in step 152 (3 Substituting it into the formula, the user's residual carbohydrate amount x is calculated.

  In step 156, the calculation unit 14 calculates the lipid consumption y of the user from the acetone concentration a acquired in the previous step 100. If the relationship between the acetone concentration a and the lipid consumption y is defined in the metabolic state calculation table 50, the lipid consumption y corresponding to the acetone concentration a is replaced with the metabolic state calculation instead of the above calculation. By reading from the table 50, it is possible to acquire the lipid consumption y of the user.

  In step 158, the calculation unit 14 substitutes the user's remaining carbohydrate amount x calculated in step 154 and the user's lipid consumption amount y calculated in step 156 into the above equations (1) and (2). The carbohydrate residual rate X and lipid consumption rate Y of the user are calculated. Then, information such as the user's acetone concentration a, carbohydrate residual amount x, lipid consumption y, carbohydrate residual rate X and lipid consumption rate Y is stored in the storage unit 20 or the like (if it is a stationary metabolic evaluation device 66). For example, it is also stored in the user information table 64 of the storage unit 62 of the user information server 60), and the metabolic state calculation process is terminated.

Moves to end the metabolic state calculation processing to step 104 of metabolic evaluation process, in step 104, the acquisition unit 12 determines the elapsed time of the acetone concentration a from the previous measurement is whether or not a predetermined time T ₁ within. As the predetermined time T ₁ , for example, a value of about several hours (specifically, 6 hours) can be used.

When the elapsed time from the previous measurement of the acetone concentration a exceeds the predetermined time T ₁ , the acetone concentration a (previous acetone concentration a_b) measured last time is the acetone concentration a (current acetone concentration a_n) measured this time. It can be determined that the time interval of the measurement timing is too wide to be used as a comparison target. For this reason, when the determination in step 104 is negative, the process proceeds to step 106, and in step 106, the output unit 16 calculates the current lipid consumption y of the user calculated in the metabolic state calculation process by the user. It replaces with the present body fat burning degree, and displays it on the display part 30 or the display part 76.

  An example of the display of the current body fat burning degree is shown in FIG. In the example shown in FIG. 12, the current body fat burnup is displayed by displaying only the number of flame images corresponding to the current body fat burnup, and the current body fat burnup is intuitive to the user. Can be grasped.

  In the next step 108, the output unit 16 displays the current carbohydrate residual rate X and lipid consumption rate Y of the user calculated in the metabolic state calculation process on the display unit 30 or the display unit 76, and the metabolic evaluation process. Exit. An example of the display of carbohydrate residual rate X and lipid consumption rate Y is shown in FIG. In the example shown in FIG. 13, the value of the residual carbohydrate ratio X and the needle meter image are displayed, and the meter needle is displayed at an angle corresponding to the current ratio of residual carbohydrate and lipid consumption. It is possible to make the user intuitively grasp the ratio of the user's current carbohydrate residue and lipid consumption, that is, the user's current metabolic state. In the example shown in FIG. 13, evaluation information (evaluation message) “I will use up soon” is also displayed, which can help the user understand the current metabolic state.

Further, if the determination in step 104 is affirmative, the process proceeds to step 110, in step 110, acquisition unit 12, the elapsed time from the measurement of the previous acetone concentration a_b determines whether a predetermined time T ₂ or more. As the predetermined time T ₂ , for example, a value of about several minutes to several tens of minutes (10 minutes as a specific example) can be used.

If the elapsed time from the measurement of the previous acetone concentration a_b of less than the predetermined time T _2, the user of the metabolic state hardly changed from the measurement of the previous acetone concentration a_b (also errors as was changed (Within range). For this reason, when the determination in step 110 is negative, the process proceeds to step 112, and in step 112, the output unit 16 notifies the message that the elapsed time from the previous measurement of the acetone concentration a_b is insufficient. Then, a message for notifying the appropriate timing of the remeasurement of the acetone concentration a is displayed on the display unit 30 or the display unit 76. If the process of step 112 is performed, it will transfer to step 106 and the process of steps 106 and 108 demonstrated previously will be performed.

On the other hand, if the elapsed time from the previous measurement of the acetone concentration a_b is greater than or equal to the predetermined time T _{2 in} the determination in step 110, it is also confirmed in the previous step 104 that the elapsed time is within the predetermined time T _1. Therefore, the previous acetone concentration a_b (metabolic state determined from the present state) can be determined as appropriate for comparison with the current acetone concentration a_n (metabolic state determined from the present state). For this reason, when determination of step 110 is affirmed, it transfers to step 114, and the acquisition part 12 acquires the last acetone concentration a_b from the memory | storage part 20 grade | etc., In step 114.

  In the next step 116, the output unit 16 acquires the metabolic evaluation information according to the previous acetone concentration a_b and the current acetone concentration a_n or the acetone concentration change amount (a_b−a_n) from the metabolic evaluation information table 52, and acquires it. The metabolic evaluation information is displayed on the display unit 30 or the display unit 76.

  An example of the display of metabolic evaluation information is shown in FIGS. 14A to 14E show metabolic evaluation information corresponding to different metabolic states in descending order of carbohydrate residual rate (or residual carbohydrate amount), that is, ascending order of lipid consumption rate (or lipid consumption amount). Are arranged. In the example shown in FIG. 14, the level of the residual carbohydrate (or residual amount of carbohydrate) is represented by the number of images displayed by adding flame to the image of the bowl filled with rice, and the image of the spoon filled with fat shows flame. The level of lipid consumption rate (or lipid consumption) is represented by the number of displayed images (FIGS. 14B to 14D) to which is added. In the example shown in FIG. 14, the lipid consumption rate (or lipid consumption) is represented by an image of the ignited match and the match box. This indicates that the lipid consumption rate (or lipid consumption) is excessive (FIG. 14E). The above display allows the user to intuitively grasp the change in metabolic state from the previous measurement of the acetone concentration a_b.

  Note that the display of metabolic evaluation information is not limited to the example shown in FIG. 14. For example, when the previous acetone concentration a_b was measured (when the determination in step 104 or step 110 was denied), FIG. When the acetone concentration a_b is measured this time (when the determination in step 110 is affirmative), according to the metabolic evaluation information acquired from the metabolic evaluation information table 52, FIGS. An image as shown in D) may be selectively displayed.

  As an example, the image of FIG. 15 (A) displayed at the time of the previous measurement of the acetone concentration a_b represents the remaining amount of sugar (or the remaining rate of carbohydrate) at that time by the number of displayed images of the hot cake, The amount of burnable body fat is represented by the number of displayed images. In addition, the images in FIGS. 15B to 15D displayed during the measurement of the acetone concentration a_b this time represent the amount of sugar consumed from the previous measurement of the acetone concentration a_b depending on the number of flame images displayed. The amount of body fat consumed from the previous measurement of the acetone concentration a_b is represented by the number of display reductions in an image simulating cells. Also when an image as shown in FIG. 15 is displayed, the user can intuitively grasp the change in the metabolic state since the previous measurement of the acetone concentration a_b.

  In the next step 118, the output unit 16 determines whether to output the reward information and the homework information. The reward information and homework information may be set in advance as to whether or not to output, or may be confirmed to the user every time whether or not the output is present. If the determination in step 118 is negative, the metabolic evaluation process ends.

  If the determination in step 118 is affirmed, the process proceeds to step 120. In step 120, the output unit 16 displays the reward information and homework information corresponding to the current residual carbohydrate amount x as a reward / homework information table. 54 and displayed on the display unit 30 or the display unit 76, and the metabolic evaluation process is terminated. As a result, the user recognizes the food that may be taken as a snack (reward) and the behavior that is recommended to be adopted as a lifestyle in the future.

  Thus, in the present embodiment, the acquisition unit 12 acquires the acetone concentration measured by the measurement unit 18, and the calculation unit 14 stores the acetone concentration a and the carbohydrate residue stored in the storage unit 20 in advance. Based on the information of the metabolic state calculation table 50 that defines the relationship and the acetone concentration a acquired by the acquisition unit 12, the carbohydrate residual and lipid consumption of the user are calculated, and the output unit 16 outputs the calculation unit 14. Since the carbohydrate residual and lipid consumption of the user calculated by the above are output, the metabolic state including the residual carbohydrate can be evaluated without requiring blood collection or the like.

  Moreover, in this embodiment, when the acquisition part 12 can acquire a user's carbohydrate intake (alpha), a user's carbohydrate intake (alpha) is acquired, and the calculating part 14 is a user by the acquisition part 12. Of the sugar concentration α stored in the storage unit 20 for each carbohydrate intake α and the remaining carbohydrates, the acetone corresponding to the user's carbohydrate intake α is obtained. Since the user's carbohydrate residual and lipid consumption are calculated based on the relationship between the concentration a and the carbohydrate residual, the evaluation accuracy of the metabolic state is improved when the user's carbohydrate intake α can be obtained.

  In the present embodiment, when the user's carbohydrate intake α is not acquired by the acquisition unit 12, the default value is used as the carbohydrate intake α, so the user's carbohydrate intake α is acquired. If not, the metabolic status can be assessed.

  Moreover, in this embodiment, the acquisition part 12 acquires a user's physical information, when the physical information containing a user's physique and body composition is acquirable, and the calculating part 14 has a user's physical information. When acquired, the consumed energy β per user's time is calculated using the acquired physical information, and the relationship between the acetone concentration a stored in the storage unit 20 for each consumed energy β per hour and the remaining carbohydrates Among them, the user's body information can be obtained because the user's carbohydrate residual and lipid consumption are calculated based on the relationship between the acetone concentration a corresponding to the energy consumption β per user and the residual carbohydrate. In this case, the evaluation accuracy of the metabolic state is improved.

  Furthermore, in this embodiment, when at least part of the user's physical information is not acquired by the acquisition unit 12, the calculation unit 14 uses the default value as the information that has not been acquired. When the energy consumption β per hour is calculated or the default value is used as the user energy consumption β per hour, when at least part of the user's physical information is not acquired Even metabolic status can be assessed.

  In the present embodiment, the acquisition unit 12 acquires the user activity level when the user activity level can be acquired, and calculates the user activity level when the acquisition unit 12 acquires the user activity level. The unit 14 calculates the consumed energy β per hour of the user using the acquired activity level, and among the relationship between the acetone concentration a stored in the storage unit 20 for each consumed energy β per hour and the residual carbohydrate. Based on the relationship between the acetone concentration a corresponding to the calculated energy consumption β per user and the remaining carbohydrate, the remaining carbohydrate and lipid consumption of the user are calculated, so that the user's activity level can be obtained. In this case, the evaluation accuracy of the metabolic state is improved.

  Moreover, in this embodiment, when the activity level of the user is not acquired by the acquisition unit 12, the calculation unit 14 uses the default value as the activity level of the user to calculate the energy consumption β per hour of the user. Since a default value is used for calculation or the user's consumed energy β per hour, the metabolic state can be evaluated even when the activity level of the user is not acquired.

  In the present embodiment, as the relationship between the acetone concentration a and the remaining carbohydrate, the relationship between the acetone concentration a and the elapsed time t after the intake of carbohydrate is defined for each carbohydrate intake α and for each consumed energy β per hour. A metabolic state calculation table 50 is stored in the storage unit 20 in advance, and the calculation unit 14 determines the acetone concentration a corresponding to the value of the carbohydrate intake α and the value of the energy consumption β per hour and the elapsed time after the carbohydrate intake. By determining the elapsed time t corresponding to the acetone concentration a from the relationship with the time t and subtracting the product of the consumed energy β per hour and the calculated elapsed time t from the value of the carbohydrate intake α, Since the user's residual carbohydrate amount is calculated and the user's lipid consumption is calculated from the acetone concentration a, the relationship between the acetone concentration a and the elapsed time t after the intake of the carbohydrate is determined according to the carbohydrate intake amount α and per hour. Energy consumption β Compared with the case without it, the evaluation accuracy of the metabolic state is improved.

  Furthermore, in this embodiment, when the acquisition unit 12 acquires the previous acetone concentration a_b and the current acetone concentration a_n, respectively, the output unit 16 stores the previous acetone concentration a_b in the storage unit 20 according to the previous acetone concentration a_b. Among the metabolic evaluation information stored in advance for each acetone concentration a_n, the metabolic evaluation information corresponding to the previous acetone concentration a_b and the current acetone concentration a_n is output. It is possible to evaluate the change in the metabolic state from the measurement of the acetone concentration a_b.

  In the present embodiment, the storage unit 20 stores the amount of change from the previous acetone concentration a_b to the current acetone concentration a_n for each previous acetone concentration a_b in a range where the previous acetone concentration a_b is less than a predetermined value. Separately, metabolic evaluation information is stored. For the range in which the previous acetone concentration a_b is a predetermined value or more, the evaluation information is stored in the previous acetone concentration a_b and in the current acetone concentration a_n. When the previous acetone concentration a_b obtained by 12 is less than the predetermined value, the metabolic evaluation information corresponding to the previous acetone concentration a_b and the amount of change from the previous acetone concentration a_b to the current acetone concentration a_n is output. If the previous acetone concentration a_b is greater than or equal to the predetermined value, the metabolic evaluation information corresponding to the previous acetone concentration a_b and the current acetone concentration a_n is output. It is possible to output appropriate metabolic evaluation information corresponding to the level of residual carbohydrate with an acetone concentration of a_b.

However, the metabolic state calculation table 50 is configured to calculate the acetone concentration a and the carbohydrate intake so that the metabolic state can be calculated with all possible combinations of the carbohydrate intake α (or γ) and the energy consumption β per hour. Since the table defines the relationship with the elapsed time t for each of the combinations, the capacity increases as the required calculation accuracy of the metabolic state increases. Therefore, the storage unit 20 that stores the metabolic state calculation table 50 is separated from the metabolic evaluation device 10 (for example, the storage unit of a server that can communicate with the metabolic evaluation device 10 functions as the storage unit 20), and the carbohydrate intake α Alternatively, the elapsed time t after carbohydrate intake corresponding to the consumed energy β per hour and the acetone concentration a may be acquired from the storage unit 20, and the remaining carbohydrate amount x may be calculated.

  In addition, since the portable metabolism evaluation device 24 is carried by each user and each portable metabolism evaluation device 24 is used by the same user, the storage unit 42 of the portable metabolism evaluation device 24 stores the above-mentioned information. Information obtained by extracting a part of all combinations may be stored as the metabolic state calculation table 50. The part to be extracted may be selected based on, for example, at least one of the sex, age group, and height of the user who uses the portable metabolic evaluation device 24, or a combination that is frequently used may be selected. .

For example, in an environment where it is easy to obtain the elapsed time t after intake of carbohydrates, the acetone concentration a and carbohydrates Information that defines the relationship between the intake amount α and the elapsed time t after carbohydrate intake and the energy consumption β per hour may be used, or the relationship between the acetone concentration a and the energy consumption β per hour may be used You may use the information prescribed | regulated according to the amount (alpha) and the elapsed time t after carbohydrate intake. It is also possible to use information that directly defines the relationship between the acetone concentration a and the residual carbohydrate amount x or the residual carbohydrate rate X.

By executing the function, it is possible to cause the apparatus to function as the metabolic evaluation apparatus 10, to obtain a measured ketone body concentration from the measuring instrument, and to perform a process of calculating and outputting a user's carbohydrate remaining and lipid consumption. is there. Moreover, if it is portable apparatuses, such as a smart phone, it can also function as an example of the metabolic evaluation apparatus 10 of the structure containing the measurement part 18 by mounting the measurement part 18 and running the metabolic evaluation program 48. FIG. is there.

The mode of acquiring and outputting from 54 has been described. However, the present invention is not limited to this, and reward information and homework information may be selected and output according to attributes such as the gender and age of the user in addition to the remaining carbohydrate amount x.
