  By the way, in recent years, a method of promoting decomposition of body fat and controlling diet by controlling the intake of carbohydrates has been known. However, diet is a struggle against appetite and is inherently difficult to last.Furthermore, when trying to control the intake of carbohydrates, it is important to understand the amount of carbohydrates contained in the diet to understand the amount of carbohydrates ingested. It is more difficult to continue to perform the troublesome task of calculating the amount.

  Then, an object of this invention is to provide the diet assistance system which can perform an effective diet continuously.

  In order to achieve the above object, a diet support system according to the present invention includes a sensor capable of continuously measuring a glucose concentration in blood or interstitial fluid, and a portable terminal capable of communicating with the sensor.

When exceeding, it has an alerting | reporting means which alert | reports the warning to the effect of suppressing intake of carbohydrates, It is characterized by the above-mentioned.

  According to such a configuration, when the integrated value of the glucose concentration acquired from the sensor exceeds the threshold value, a warning that the intake of the carbohydrate should be suppressed is notified, so the intake of the carbohydrate is suppressed according to the warning. Thus, the decomposition of body fat can be promoted, and an effective diet can be performed. In addition, for example, since there is no troublesome calculation of the amount of carbohydrates contained in a meal or the like, the stress associated with dieting can be reduced, and effective dieting can be continued.

  In the diet support system described above, the mobile terminal may include a reset unit that resets the integrated value at a predetermined time of the day.

  According to this, since the intake of carbohydrates can be controlled in units of one day, dieting can be performed more effectively.

  In the diet support system described above, the integrating means may be configured to integrate a value C-C1 obtained by subtracting a predetermined value C1 from the glucose concentration C acquired from the sensor.

  According to this, since the minimum necessary amount of carbohydrate can be ensured, excessive dieting can be suppressed.

  In the diet support system described above, the integrating means may be configured to determine the predetermined value C1 based on a history of glucose concentration C.

  According to this, the amount of carbohydrate required can be determined for each individual, and the intake of carbohydrate can be controlled for the amount exceeding the amount required for the individual, thus suppressing excessive dieting However, an effective diet can be performed.

  In the diet support system described above, the integrating means may be configured to determine the predetermined value C1 based on an average value of the glucose concentration C during a period when the change gradient of the glucose concentration C is equal to or less than a predetermined gradient. .

  According to this, since the predetermined value C1 can be determined based on the glucose concentration as a base before the glucose concentration greatly increases due to eating or the like, the predetermined value C1 corresponding to the amount of necessary carbohydrate is It can be determined with high accuracy.

In the diet support system described above, when the glucose concentration is rising, the notification unit corrects the threshold value to decrease or corrects the integrated value to increase. can do.
For example, in the diet support system described above, when the glucose concentration is rising above a predetermined gradient, the notification unit corrects the threshold value to decrease or increases the integrated value. It can be set as the structure corrected so that it may be made.

  According to this, when the glucose concentration is rising due to eating, etc., the integrated value of the glucose concentration easily exceeds the threshold value, so a warning that sugar intake should be suppressed is notified early. can do. As a result, a warning that sugar intake should be suppressed can be notified during the intake of carbohydrate. As a result, it is possible to promote early response such as raising the intake of carbohydrates early, so that excessive intake of carbohydrates can be suppressed, leading to an effective diet.

In the diet support system described above, the notification unit may notify the warning again after a predetermined time has elapsed after notifying the warning.
In the diet support system described above, the notifying unit notifies the warning again when the integrated value exceeds a second threshold value larger than the threshold value after notifying the warning. It can be set as the structure to do.

  According to this, it is possible to more reliably notify a warning that sugar intake should be suppressed.

  In the diet support system described above, the warning may be configured to include taking an alternative food for carbohydrate restriction in the next meal.

  According to this, since the intake of the alternative food for carbohydrate restriction can be promoted at an appropriate timing, the diet can be effectively performed.

  The diet support system described above may further include a robot capable of generating voice, and the notification unit may cause the robot to notify the warning by voice.

  This makes it easier to notice a warning that sugar intake should be suppressed. Also, by alerting the content of the warning by voice so that the robot speaks, it is possible to maintain motivation and continue dieting.

It is a flowchart which shows an example of the process which determines a predetermined value. It is a flowchart which shows an example of the process which correct | amends a predetermined threshold value. It is a figure explaining the effect of a diet assistance system.

Next, an embodiment of the invention will be described.
As shown in FIG. 1, the diet support system 1 is a system that supports a person who performs a diet (Dieter H), specifically, a person who performs a diet (a carbohydrate restriction diet) that controls the intake of carbohydrates. The diet support system 1 includes a sensor 2, a mobile terminal 3, and a robot 4.

  The sensor 2 is a sensor capable of continuously measuring a glucose concentration in blood or interstitial fluid (hereinafter also referred to as “blood glucose level” in the present specification). Specifically, the sensor 2 can be attached to a part of the body such as the arm of the dieter H, and when the sensor 2 is attached to a part of the body of the dieter H, a detection unit (not shown) enters under the stratum corneum and the blood sugar level. It is configured to be able to measure continuously. The sensor 2 is configured to transmit a measurement result to the mobile terminal 3 by wireless communication using the Internet or BLUETOOTH (registered trademark). As such a sensor 2, for example, a microsensor disclosed in US Pat. No. 9,008745 and US Pat. No. 9,182,368 can be used.

  The portable terminal 3 is a portable computer used by the dieter H. Although the kind in particular of portable terminal 3 is not ask | required, Specifically, they are a smart phone, a tablet terminal, a wearable computer etc., for example. The portable terminal 3 is configured to be able to communicate with the sensor 2 and the robot 4 by wireless communication. The mobile terminal 3 stores an application dedicated to the diet support system 1.

  As shown in FIG. 2, the mobile terminal 3 includes a data acquisition unit 31, an integration unit 32, a notification unit 33, a reset unit 34, a display unit 35 that configures the screen of the mobile terminal 3, and a storage unit 39. have. Specifically, the portable terminal 3 functions as the data acquisition unit 31, the integration unit 32, the notification unit 33, and the reset unit 34 by starting an application dedicated to the diet support system 1 stored in the storage unit 39.

  The data acquisition means 31 has a function of acquiring the glucose concentration measured by the sensor 2 from the sensor 2 at a predetermined timing. The predetermined timing is, for example, every tens of seconds to every tens of minutes, such as every five minutes. The timing for acquiring the glucose concentration may be a preset timing, or may be set freely by the dieter H by operating the portable terminal 3. Note that the glucose concentration does not need to be a unit such as “mg / dL” in calculation, and may be, for example, a numerical value of the charge measured by the sensor 2.

  The integrating unit 32 has a function of calculating an integrated value of the glucose concentration acquired from the sensor 2 by the data acquiring unit 31. Specifically, the integrating unit 32 calculates an integrated value ∫C by integrating a value C−C1 obtained by subtracting a predetermined value C1 from the glucose concentration C acquired from the sensor 2.

  Here, FIG. 3 is a diagram showing changes in blood glucose level for one day. The integrated value ∫C corresponds to the area between the measured glucose concentration C and the predetermined value C1. In addition, the predetermined value C1 corresponds to a blood glucose level that serves as a base before the blood glucose level significantly increases due to eating. Furthermore, the predetermined value C1 corresponds to the minimum necessary blood glucose level.

  The integrating unit 32 determines the predetermined value C1 based on the history of the glucose concentration C that the data acquiring unit 31 has acquired from the sensor 2 so far. Specifically, the integrating unit 32 determines the predetermined value C1 based on the average value of the glucose concentration C during a period in which the change gradient of the glucose concentration C is equal to or less than the predetermined gradient.

As an example, the integrating means 32 has an absolute value of a value obtained by subtracting the previous value C _n−1 from the glucose concentration (current value) C _n acquired from the sensor 2 _equal to or less than a preset first gradient determination threshold value ΔCth1. In this case, the glucose concentration (current value) C _n is stored in the storage unit 39, the average value of the glucose concentration C stored so far is determined as a predetermined value C1, and used for the calculation of the integrated value ∫C. .

  The informing means 33 has a function of informing a warning that sugar intake should be suppressed when the integrated value ∫C of the glucose concentration calculated by the integrating means 32 exceeds a predetermined threshold value ∫Cth. Yes.

  Specifically, when the integrated value ∫C exceeds the threshold value ∫Cth, the notification unit 33 displays a warning to the effect that sugar intake should be suppressed on the display unit 35. This warning includes taking the alternative food 5 (see FIG. 1) for restricting carbohydrates in the next meal. As an example, when the integrated value ∫C exceeds the threshold value ∫Cth, the notification means 33 displays “Warning! Today's carbohydrate reference value has been exceeded in the previous meal. "Please replace it with XX (product name of alternative food 5 for restricting carbohydrates, etc.)".

  In addition, when the integrated value ∫C exceeds the threshold value ∫Cth, the notifying unit 33 transmits a signal to the robot 4 in order to notify the robot 4 of a warning that sugar intake should be suppressed.

  The threshold value ∫Cth corresponds to the amount of carbohydrates that can be taken per day. The integrated value ∫C exceeds the threshold value ∫Cth means that the area between the glucose concentration C and the predetermined value C1 shown in FIG. Of the amount).

  In the present embodiment, the notification means 33 corrects the threshold value ∫Cth to decrease when the glucose concentration is increasing. Specifically, the notification means 33 corrects the threshold value ∫Cth to decrease when the glucose concentration is rising above a predetermined gradient.

As an example, the integrating means 32 is a case where the value obtained by subtracting the previous value C _n−1 from the glucose concentration (current value) C _n acquired from the sensor 2 is _equal to or greater than a preset second gradient determination threshold value ΔCth2. The threshold value ∫Cth is a value corrected so as to decrease by multiplying the initial value し き い 値 Cth0 of the threshold value by a predetermined coefficient C2 of less than 1 such as 0.95, for example. The second gradient determination threshold value ΔCth2 is set to a value larger than the first gradient determination threshold value ΔCth1.

The accumulating unit 32 determines that the value obtained by subtracting the previous value C _n−1 from the current value C _{n of} the glucose concentration is less than the second gradient determination threshold value ΔCth2, that is, when the glucose concentration is not increasing. The threshold value initial value ∫Cth0 is set as the threshold value ∫Cth.

  The threshold value ∫Cth (specifically, the initial value of the threshold value ∫Cth0) may be a preset value, or the dieter H operates the portable terminal 3 from a plurality of preset values. It may be possible to select freely. Further, the threshold value ∫Cth (the initial value of the threshold value ∫Cth0) may be set freely by the dieter H.

  Moreover, in this embodiment, the alerting | reporting means 33 alert | reports a warning again after predetermined time progress, after alert | reporting a warning when the integrated value ∫C of glucose concentration exceeds threshold value 報 知 Cth. Specifically, the notification means 33 notifies the warning and displays the warning again on the display unit 35 after a predetermined time has elapsed, and again transmits a signal for notifying the robot 4 of the warning. The predetermined time is several minutes to several hours, such as 10 minutes. The predetermined time may be a preset time or may be set freely by the dieter H.

  In the present embodiment, the notification unit 33 resets the integrated value ∫C by the reset unit 34 (to be described later) after notifying the warning again in order to prevent the dieter H from feeling bothered by repeated warnings. After that, the warning is not notified until the integrated value ∫C exceeds the threshold value ∫Cth.

  The reset means 34 has a function of resetting the accumulated value ∫C to zero by resetting it at a predetermined time of the day. The predetermined time is preferably a time in a time zone in which the glucose concentration does not change significantly, such as a time zone in which the dieter H is sleeping. As an example, the predetermined time is any time between 0-6 am. The predetermined time may be a preset time or may be set freely by the dieter H according to the life cycle.

  The storage unit 39 is a device that stores an application dedicated to the diet support system 1, glucose concentration C, a predetermined value C1, an integrated value グ ル コ ー ス C of glucose concentration, various threshold values, and the like.

  The robot 4 is a robot installed in a place close to the dieter H. It is desirable that the robot 4 has, for example, a human-type or animal-type shape so that the dieter H can be attached. The robot 4 is configured to generate at least sound. The robot 4 may be configured to be able to talk and move.

  When the robot 4 receives a signal transmitted from the notification means 33 of the mobile terminal 3 for notifying the robot 4 of a warning, the robot 4 is configured to notify the warning by voice. As an example, the robot 4 issues a warning to the dieter H with a voice such as “The carbohydrate reference value of today has been exceeded by the previous meal. Please replace the next meal with XX”.

  Next, an example of the operation of the mobile terminal 3 in the diet support system 1 will be described. The mobile terminal 3 repeatedly executes the process of the flowchart shown in FIG. Here, Fa is a flag indicating a history of warnings, and the initial value is 0, and becomes 1 when the first warning is notified, and becomes 2 when the second warning is notified.

  As shown in FIG. 4, the portable terminal 3 determines whether or not the integrated value ∫C is a predetermined time to be reset (S11), and if it is not the predetermined time (S11, No), the glucose concentration C is set. It is determined whether it is a predetermined timing to be acquired (S21). If it is not the predetermined timing (S21, No), the mobile terminal 3 ends the current process. On the other hand, when it is a predetermined timing (S21, Yes), the portable terminal 3 acquires the glucose concentration C from the sensor 2 (S22).

Then, the mobile terminal 3 determines a predetermined value C1 used to calculate the integrated value （C (S31). Specifically, as illustrated in FIG. 5, the mobile terminal 3 determines that the absolute value of the value obtained by subtracting the previous value C _n−1 from the current value C _n of the acquired glucose concentration is _equal to or less than the first gradient determination threshold value ΔCth1. It is determined whether or not (S311). Then, if it is not more than the first gradient determination threshold ΔCth1 (S311, Yes), the mobile terminal 3 stores the current value _{C n} (S312), calculates an average value of the glucose concentration C stored so far Then, the current predetermined value C1 is determined (S313). On the other hand, when it is not equal to or less than the first gradient determination threshold value ΔCth1 (S311, No), the mobile terminal 3 ends the process shown in FIG. In this case, the portable terminal 3 uses the same predetermined value C1 as the previous time in the processing after step S31 shown in FIG.

  After step S31, the portable terminal 3 calculates the integrated value ∫C by integrating the value obtained by subtracting the predetermined value C1 from the glucose concentration C (S32). Specifically, the mobile terminal 3 adds the value obtained by subtracting the predetermined value C1 determined in step S31 from the glucose concentration C acquired in step S22 to the previous value of the integrated value ∫C, thereby obtaining the integrated value ∫C. This time value is calculated.

Further, the mobile terminal 3 corrects the threshold value ∫Cth (S41). Specifically, as illustrated in FIG. 6, the mobile terminal 3 determines whether or not the value obtained by subtracting the previous value C _n−1 from the current value C _n of the glucose concentration is _equal to or greater than the second gradient determination threshold value ΔCth2. Is determined (S411). If the glucose concentration is rising above the second gradient determination threshold value ΔCth2 (S411, Yes), the mobile terminal 3 multiplies the initial threshold value ∫Cth0 by a predetermined coefficient C2 less than 1. The value corrected so as to decrease is set as a threshold value ∫Cth (S412). Further, when the glucose concentration is not higher than the second gradient determination threshold value ΔCth2 (S411, No), the portable terminal 3 sets the initial threshold value ∫Cth0 as the threshold value ∫Cth (S413). .

  After step S41, the mobile terminal 3 determines whether or not the integrated value ∫C exceeds the threshold value ∫Cth (S42). When the integrated value ∫C does not exceed the threshold value ∫Cth (S42, No), the mobile terminal 3 ends the current process. On the other hand, when the integrated value ∫C exceeds the threshold value ∫Cth (S42, Yes), the mobile terminal 3 determines whether or not the flag Fa indicating the history of warning is 2 (S43). If the flag Fa is not 2 (S43, No), the mobile terminal 3 determines whether or not the flag Fa is 1 (S44).

  When the flag Fa is not 1 (S44, No), the mobile terminal 3 notifies a warning that sugar intake should be suppressed (S45). Specifically, a warning message is displayed on the display unit 35 and the robot 4 is notified of the warning by voice. Further, the mobile terminal 3 changes the flag Fa from 0 to 1 (S46), and ends the current process.

  In step S44, when the flag Fa is 1 (S44, Yes), since the first warning has already been notified, the mobile terminal 3 notifies the warning. Specifically, the flag Fa is changed from 0. It is determined whether or not a predetermined time has elapsed since the change to 1 (S51). If the predetermined time has not elapsed (S51, No), the mobile terminal 3 ends the current process without notifying the warning. On the other hand, when the predetermined time has elapsed (S51, Yes), the mobile terminal 3 notifies the warning that carbohydrate intake should be suppressed again (S52). Further, the mobile terminal 3 changes the flag Fa from 1 to 2 (S53), and ends the current process.

In step S43, when the flag Fa is 2 (S43, Yes), since the warning is notified again, the portable terminal 3 does not notify the warning in order to prevent the dieter H from feeling troublesome. This processing is terminated.
In step S11, when the predetermined time comes (S11, Yes), the mobile terminal 3 resets the integrated value ∫C (S12), sets the flag Fa to 0 (initial value) (S13), and this time Terminate the process.

  According to the diet support system 1 of the present embodiment described above, as shown in FIG. 7, for example, at the time of lunch, the dieter H ingests carbohydrates and the blood sugar level greatly increases, and is acquired from the sensor 2 at time t1. When the integrated value ∫C of the glucose concentration exceeds the threshold value ∫Cth, a warning that the intake of carbohydrates should be suppressed is notified, and then the dieter H suppresses the intake of carbohydrates according to the warnings. Overall, the intake of carbohydrates can be reduced. Thereby, since excessive intake of saccharide | sugar can be suppressed, decomposition | disassembly of body fat can be accelerated | stimulated and an effective diet can be performed.

  In addition, according to the diet support system 1 of the present embodiment, it is only necessary to suppress the intake of carbohydrates according to the warning, so for example, the troublesomeness of the dieter H itself calculating the amount of carbohydrates contained in the meal etc. one by one. In addition, the stress associated with dieting can be reduced. Thereby, an effective diet can be continuously performed.

  In the diet support system 1 of the present embodiment, since the mobile terminal 3 has the reset means 34 that resets the integrated value ∫C to a predetermined time of the day (for example, time t0 in FIG. 7), Quality intake can be controlled on a daily basis. Thereby, a diet can be performed more effectively.

  Moreover, in the diet support system 1 of this embodiment, since the integrating | accumulating means 32 integrates | accumulates the value which subtracted predetermined value C1 from the glucose concentration C acquired from the sensor 2, the minimum amount of required carbohydrates is. Can be secured. Thereby, it can suppress that an excessive diet is performed.

  Moreover, since the integrating | accumulating means 32 determines predetermined value C1 based on the log | history of glucose concentration C, it can determine the quantity of required carbohydrate for every dieter H, and exceeds the quantity required for the said dieter H. You can control carbohydrate intake for minutes. Thereby, it is possible to perform an effective diet while suppressing an excessive diet.

  Further, the integrating means 32 determines the predetermined value C1 based on the average value of the glucose concentration C during the period when the change gradient of the glucose concentration C is equal to or less than the predetermined gradient. The predetermined value C1 can be determined based on the previous base glucose concentration. Thereby, the predetermined value C1 corresponding to the required amount of carbohydrate can be determined with high accuracy.

  In the diet support system 1 of the present embodiment, the notification means 33 corrects the threshold value ∫Cth to decrease when the glucose concentration is increasing. Is increasing, the integrated value ∫C of the glucose concentration tends to exceed the threshold value ∫Cth. Thereby, the warning that the intake of carbohydrates should be suppressed can be notified early. Furthermore, a warning that sugar intake should be suppressed can be notified during the intake of carbohydrate, for example, before the end of a meal. As a result, the dieter H can be encouraged to respond early, such as by cutting up the meal early, so that excessive intake of carbohydrates can be suppressed, leading to an effective diet.

  Moreover, since the alerting | reporting means 33 alert | reports a warning again after predetermined time progress, after alerting | reporting a warning, the warning that the intake of saccharide | sugar should be suppressed can be reliably notified by the dieter H. FIG.

  Moreover, since the warning notified by the notification means 33 includes that the substitute food 5 for restricting carbohydrates should be taken in the next meal, the intake of the substitute food 5 can be prompted at an appropriate timing. Thereby, a diet can be performed effectively.

  Moreover, since the alerting | reporting means 33 alert | reports a warning with the voice by the robot 4, it becomes easy for the dieter H to notice the warning that the intake of carbohydrates should be suppressed. Further, by notifying the content of the warning by voice so that the robot 4 speaks, the motivation of the dieter H can be maintained and the diet can be continuously performed.

  Although one embodiment of the invention has been described above, the present invention is not limited to the embodiment. About a concrete structure, it can change suitably in the range which does not deviate from the meaning of invention as follows.

  For example, in the embodiment, the notification unit 33 is configured to notify the warning again after a predetermined time has elapsed after notifying the warning, but is not limited thereto. For example, the notification means 33 is configured to notify the warning again when the integrated value ∫C exceeds the second threshold value ∫Cth larger than the threshold value ∫Cth after notifying the warning. It may be.

  Specifically, in the flowchart shown in FIG. 4, instead of step S51, a step of determining whether or not the integrated value ∫C exceeds the second threshold value ∫Cth2 is provided. When the threshold value ∫Cth2 of 2 is not exceeded, the warning is not notified again, and when the integrated value ∫C exceeds the second threshold value ∫Cth2, the warning is notified again. You may comprise. Even with such a configuration, it is possible to reliably notify the dieter H of a warning that sugar intake should be suppressed.

  In the embodiment, the notification unit 33 is configured to correct the threshold value ∫Cth when the glucose concentration is increasing, but is not limited thereto. For example, when the glucose concentration is increasing, the notification means 33 may be configured to correct the increase so that the integrated value 、 C is increased instead of decreasing the threshold value ∫Cth.

Specifically, when the glucose concentration is rising above a predetermined gradient, for example, when C _n −C _n−1 ≧ ΔCth2, the notification unit 33 sets the integrated value ∫C to 1.05 or the like. Alternatively, a correction may be made so as to increase the integrated value ∫C by multiplying by a predetermined coefficient C3 larger than 1. Even with such a configuration, when the glucose concentration is increasing, the integrated value ∫C tends to exceed the threshold value ∫Cth, so that a warning can be notified early.

  Note that the method of decreasing the threshold value ∫Cth or increasing the integrated value ∫C is not limited to the method of multiplying the coefficients C2 and C3 as described above. It is also possible to decrease the value by subtracting or to increase the integrated value ∫C by adding the second value.

  Further, the notification means 33 may be configured not to perform the process of step S41 in the flowchart shown in FIG. That is, the notification means 33 may be configured not to correct the threshold value ∫Cth or the integrated value ∫C (not change according to the glucose concentration).

  Further, in the embodiment, when the integrated value ∫C exceeds the threshold value ∫Cth, the notifying unit 33 displays a warning on the display unit 35 of the mobile terminal 3 and causes the robot 4 to notify the warning. Although comprised, it is not limited to this. For example, when the diet support system 1 includes the robot 4, the notification unit 33 may notify the robot 4 only of the warning and the mobile terminal 3 may not notify the warning.

  In addition, the notification unit 33 does not display a warning message on the display unit 35 of the mobile terminal 3, for example, causes the speaker of the mobile terminal 3 to output a warning sound or a voice, or the vibration function of the mobile terminal 3. You may be comprised so that a warning may be alert | reported by vibrating the portable terminal 3. FIG. Further, the notification unit 33 may be configured to cause the portable terminal 3 to notify a warning that combines two or more of message display, sound generation, vibration, and the like.

  In the embodiment, the integrating means 32 is configured to determine the predetermined value C1 based on the glucose concentration C stored so far, when determining the predetermined value C1. It is not limited to. For example, the integrating means 32 may be configured to determine a predetermined value C1 based on a predetermined number of glucose concentrations C close to the present among the glucose concentrations C stored so far. According to this, the predetermined value C1 according to the recent constitution of the dieter H can be obtained.

  Moreover, in the said embodiment, although the integrating | accumulating means 32 was comprised so that predetermined value C1 might be determined based on the log | history of glucose concentration C, it is not limited to this. For example, the predetermined value C1 may be a fixed value set in advance. Further, the predetermined value C1 may be a value calculated from information such as age and weight input to the mobile terminal 3 by the dieter H.

  Moreover, the integrating | accumulating means 32 is good also as a structure which does not perform the process of step S31 of the flowchart shown in FIG. That is, the integrating means 32 may be configured to calculate the integrated value by integrating the glucose concentration C acquired from the sensor 2 as it is without subtracting the predetermined value C1.

  Moreover, in the said embodiment, although the reset means 34 was comprised so that integrated value ∫C might be reset to the predetermined time of the day, it is not limited to this. For example, the reset means 34 may be configured to reset the integrated value ∫C not for each day but for a time longer than one day, for example, every week. Further, the reset means 34 may be configured to reset the integrated value ∫C every time shorter than one day, for example, every 8 hours.

  Moreover, in the said embodiment, although the diet assistance system 1 was comprised including the sensor 2, the portable terminal 3, and the robot 4, it is not limited to this. For example, the diet support system 1 may further include a server that can transmit and receive information regarding the dieter H (user) to and from the mobile terminal 3. The server is, for example, a device managed by a company that provides the diet support system 1. The server receives information about the user such as an integrated value transmitted from the mobile terminal 3, analyzes the data, and is suitable for the user. It can be configured to transmit information, advice, etc. regarding diet to the mobile terminal 3 or the robot 4.

  Moreover, in the said embodiment, although the diet assistance system 1 was further provided with the robot 4 other than the sensor 2 and the portable terminal 3, it is not limited to this, Even if it is the structure which does not include a robot. Good.

  Moreover, you may implement this invention combining each element demonstrated by above-described embodiment and modification arbitrarily.
