MODE FOR CARRYING OUT THE INVENTION

[0011] (Knowledge on which the present disclosure is based) In health promotion, prevention of obesity has an important position. Obesity can be divided into "visceral fat type obesity" and "subcutaneous fat type obesity", and it is known that the former has a higher risk of developing lifestyle-related diseases. For the prevention of obesity, it is expected to be effective by reviewing the diet and incorporating continuous exercise. Generally, in health checkups and specific health guidance, etc., there are many subjects (users) who follow the guidance of doctors or specialists and work on improving diet (including weight loss) and exercise for the purpose of improving obesity.

[0012] In conventional technologies such as the above-mentioned Patent Documents 1 and 2, changes in metabolism are estimated based on bioelectrical impedance change information, and guidance information for safely losing weight (dieting) is generated and output. However, the relationship between the results of specific efforts (such as reviewing diet and implementing continuous exercise) for improving the life of the subject and the changes in bioelectrical impedance has not been linked, and it is difficult for the subject to determine whether the life has been improved correctly.

[0013] Also, in conventional technologies, a plus determination or a minus determination is displayed according to the increase or decrease in visceral fat level to evaluate the progress of weight loss. However, since specific efforts for improving the life of the subject are not comprehensively judged, it is difficult to evaluate whether weight loss (dieting) is being carried out correctly.

[0014] In view of the above problems, the inventors of the present invention have intensively studied, and in evaluating the efforts of improvement actions, after determining whether or not to enter a stagnation period in which the amount of change in body weight and / or body fat percentage shows a tendency to stagnate, when the possibility of the stagnation period is high, It has been found that providing appropriate intervention and support is effective in improving the user's lifestyle.

[0015] A lifestyle improvement system according to a first aspect of the present disclosure includes body composition information indicating a body evaluation value related to the body composition of a first user measured at each of a plurality of timings, and diet and exercise of the first user performed for each of a plurality of periods delimited by the plurality of timings. An acquisition unit that acquires lifestyle information including actions, a first calculation unit that calculates a tendency of change in the body evaluation value for each of the plurality of periods, and for each of the plurality of periods, based on the eating behavior in the period, calculates the energy intake of the first user, and A second calculation unit that calculates the energy consumption of the first user based on the exercise behavior in the period, and based on the tendency of change in the body evaluation value, the energy intake, and the energy consumption, determines whether a first period among the plurality of periods is a stagnation period in which it is difficult for the body evaluation value of the first user to improve. A determination unit, and a notification unit that, when the first period is a stagnation period, notifies the terminal of the first user of support information including information indicating that it is a stagnation period.

[0016] According to this, based on the tendency of the change in the body evaluation value, the intake energy, and the consumption energy, it is possible to determine whether the first period is a stagnant period, and notify the first user of the information including the determination result. Therefore, the first user can recognize whether the state of the first user is a stagnant period, and can suppress the decrease in the motivation to improve the lifestyle. Thus, it is possible to effectively support the improvement of the lifestyle of the first user.

[0017] The lifestyle improvement system according to the second aspect of the present disclosure is the lifestyle improvement system according to the first aspect, wherein the body evaluation value includes the weight of the first user and a body fat value related to the body fat amount, and the first calculation unit calculates at least one of whether the weight is decreasing and whether the body fat amount is decreasing as the tendency of the change, and the determination unit calculates the energy balance in the third period, which is a continuous period including the first period and the second period among the plurality of periods, based on the total intake energy and the total consumption energy in the third period, and determines whether the energy balance is less than a reference value. When the tendency of the change indicates that the weight is not decreasing or the body fat amount is not decreasing, and the energy balance is less than the reference value, it is determined that the first period is the stagnant period.

[0018] Therefore, it is possible to appropriately determine whether it is a stagnant period in which the weight or body fat amount does not tend to decrease while working on improving the lifestyle. Thus, it is possible to effectively support the improvement of the lifestyle of the first user.

[0019] The lifestyle improvement system according to the third aspect of the present disclosure is the lifestyle improvement system according to the second aspect, wherein the reference value is determined based on the attribute information of the first user, and the attribute information includes the age, gender, and lifestyle of the first user.

[0020] Therefore, it is possible to appropriately determine whether or not the first user is engaged in actions to improve their lifestyle according to the attribute information of the first user.

[0021] The lifestyle improvement system according to the fourth aspect of the present disclosure is a lifestyle improvement system according to any one of the first aspect to the third aspect, wherein the eating behavior includes intake information regarding the intake amounts of nutrients including sugar content, lipid, protein, and salt contained in the foods consumed by the first user during the corresponding period.

[0022] Therefore, it is possible to appropriately calculate the intake energy of the first user.

[0023] The lifestyle improvement system according to the fifth aspect of the present disclosure is a lifestyle improvement system according to any one of the first aspect to the fourth aspect, further comprising a storage unit that stores body composition information, intake energy, and consumption energy of each of a plurality of second users whose body evaluation values have been improved after the stagnation period, during a consecutive fourth period after the stagnation period of the corresponding second user. The storage unit further stores the attribute information of each of the plurality of second users. When the first period is a stagnation period, the notification unit refers to the storage unit to identify at least one second user having attribute information similar to the attribute information of the first user among the plurality of second users, generates support information further including the body composition information, intake energy, and consumption energy of the identified at least one second user during the stagnation period, and notifies the generated support information to the terminal of the first user.

[0024] For this reason, it is possible to execute actions to improve the lifestyle by being encouraged by the achievements of other users with similar attribute information who have overcome the stagnation period. Therefore, it is possible to suppress a decrease in the motivation to take actions to improve the lifestyle.

[0025] The control method according to the sixth aspect of the present disclosure is a control method for a lifestyle improvement system having one or more processors. The one or more processors obtain body composition information indicating a body evaluation value related to the body composition of a first user measured at each of a plurality of timings, and lifestyle information including the eating and drinking behavior and exercise behavior of the first user performed at each of a plurality of periods delimited by the plurality of timings. For each of the plurality of periods, a tendency of change in the body evaluation value is calculated. For each of the plurality of periods, the energy intake of the first user is calculated based on the eating and drinking behavior in the period, and the energy consumption of the first user is calculated based on the exercise behavior in the period. Based on the tendency of change in the body evaluation value, the energy intake, and the energy consumption, it is determined whether a first period among the plurality of periods is a stagnant period in which it is difficult for the body evaluation value of the first user to improve. If the first period is a stagnant period, support information including information indicating that it is a stagnant period is notified to the terminal of the first user.

[0026] According to this, based on the tendency of change in the body evaluation value, the energy intake, and the energy consumption, it is possible to determine whether the first period is a stagnant period and notify the first user of information including the determination result. Therefore, the first user can recognize whether the state of the first user is a stagnant period, and it is possible to suppress a decrease in the motivation for actions to improve the lifestyle. Thus, it is possible to effectively support the improvement of the lifestyle of the first user.

[0027] The program according to the seventh aspect of the present disclosure is a program for causing a computer to execute the control method according to the sixth aspect.

[0028] Note that these general or specific aspects may be realized by an apparatus, an integrated circuit, a computer program, or a non-transitory recording medium such as a computer-readable CD-ROM, or may be realized by any combination of an apparatus, an integrated circuit, a computer program, and a non-transitory recording medium.

[0029] Hereinafter, embodiments will be described in detail with reference to the drawings as appropriate. However, detailed descriptions that are more than necessary may be omitted. For example, detailed descriptions of well-known matters and duplicate descriptions of substantially the same configurations may be omitted. This is to avoid making the following description unnecessarily redundant and to facilitate understanding by those skilled in the art.

[0030] Note that the inventor provides the accompanying drawings and the following description for those skilled in the art to fully understand the present disclosure, and does not intend to limit the subject matter described in the claims thereby.

[0031] (Embodiment) [Configuration] FIG. 1 is a diagram showing an example of a functional block diagram of a lifestyle improvement system according to an embodiment.

[0032] As shown in FIG. 1, the lifestyle improvement system 1 includes a server 10 and mobile terminals 20 and 30. The server 10 and the mobile terminals 20 and 30 are communicably connected to each other by a network 40. The network 40 may be a general-purpose line such as the Internet or a dedicated line. The mobile terminal 20 is a terminal carried by the first user. The mobile terminal 30 is a terminal carried by the second user. The first user is, for example, a user to be supported who receives improvement of lifestyle. The second user is, for example, a support user who supports the improvement of the lifestyle of the first user. Here, the support is, for example, support for improving the eating habits of the first user and cooking of the meals of the first user. Further, the support is not limited to cooking of the meals of the first user, and may include support for improving the overall lifestyle not limited to the eating habits by promoting the regular life of the first user and the exercise of the first user or working together.

[0033] (Server) Server 10 is a cloud server that provides information for assisting the improvement of the living habits of the first user to the first user and the second user. Server 10 includes an acquisition unit 11, a storage unit 12, a first calculation unit 13, a second calculation unit 14, a determination unit 15, and a notification unit 16. Note that Server 10 includes a processor and a memory. The functions of Server 10 may be realized by the processor executing a program stored in the memory.

[0034] The acquisition unit 11 is a communication IF (Interface) that acquires various information from the mobile terminals 20 and 30 by communicating with them via the network 40. The acquisition unit 11 may acquire the body composition information and the living information of the first user from the mobile terminal 20.

[0035] The body composition information indicates body evaluation values related to the body composition of the first user measured at each of a plurality of timings. The body evaluation value is, for example, at least one of the weight and the body fat value of the first user. Note that the body fat value is a value related to the amount of body fat of the first user, and may be, for example, the body fat percentage or the bioimpedance. The acquisition unit 11 may acquire the body composition information from the mobile terminal 20. The mobile terminals 20 and 30 may store the body composition information including the measurement results by communicating with a body composition meter that measures the weight and the body fat value of the first user. The mobile terminals 20 and 30 may store the measurement results by the body composition meter as the body composition information by being input by the user. Note that the acquisition unit 11 may directly acquire the body composition information including the measurement results from the body composition meter.

[0036] The living information includes dietary information indicating the eating and drinking behaviors of the first user conducted for each of a plurality of periods delimited at a plurality of timings, and exercise information indicating the exercise behaviors of the first user. Note that the plurality of timings may be timings on a daily basis, may be timings every two days, or may be timings for each period of three days or more. Each of the plurality of periods may be one day (24 hours), may be two days (48 hours), or may be a period of three days or more (a period of 72 hours or more). Also, the plurality of timings may be timings for each period of less than one day, and each of the plurality of periods may be a period of less than one day.

[0037] The dietary information is information regarding the diet of the first user generated from the information input by the first user via the health management app of the mobile terminal 20. The dietary information includes, for example, the types and amounts of beverages the first user drank and the types and amounts of foods the first user ate during the corresponding period. The health management app is an app for managing the health status of the first user and operates on the mobile terminals 20 and 30. The dietary information includes the frequency of taking pictures of the meals the first user eats, pictures of the meals, the frequency of eating out, the amount or frequency of snacks, the evaluation of the taste of the meals eaten, etc. The dietary information may include the menu of the meal. Also, the acquisition unit 11 may acquire the menu of the meal as dietary information by estimating the menu of the meal from the picture of the meal. The acquisition unit 11 may acquire the nutritional components by estimating the nutritional components of the meal from the menu of the meal. The nutritional components include the energy amount of the meal, the salt content, etc. Note that the acquisition unit 11 may acquire living information indicating the daily life behaviors of the first user, not limited to the dietary information. The living information may include information regarding basic behaviors essential for a person to conduct daily life, such as the sleep and excretion of the first user, in addition to the dietary information regarding the meals of the first user.

[0038] Also, the acquisition unit 11 may acquire app information regarding the health management app of the mobile terminal 20. The app information includes the frequency of the first user browsing the health management app of the mobile terminal 20, the view count of the guidance content for the first user of the health management app, etc.

[0039] In addition, the acquisition unit 11 may acquire the biological information of the first user obtained from an activity meter (not shown). The biological information may include the pulse, body movement, number of steps, etc. of the first user. The activity meter includes a heart rate sensor, a triaxial acceleration sensor, and a triaxial angular velocity sensor. The activity meter may transmit the obtained biological information to the server 10 via the mobile terminal 20 by communicating with the mobile terminal 20, or may transmit the obtained biological information to the server 10 by communicating with the network 40. That is, the acquisition unit 11 may acquire the biological information via the mobile terminal 20, or may directly acquire the biological information from the activity meter without passing through the mobile terminal 20. Note that the exercise behavior included in the living information is specified based on the biological information.

[0040] The storage unit 12 stores the body composition information and the living information acquired by the acquisition unit 11. The acquisition unit 11 periodically acquires the body composition information and the living information. Note that the timing of acquiring the body composition information and the timing of acquiring the living information may or may not coincide. The acquisition unit 11 may acquire new body composition information according to the timing when the body composition information is newly stored in the mobile terminal 20. The acquisition unit 11 may acquire new living information according to the timing when the living information is newly stored in the mobile terminal 20. The acquisition unit 11 may acquire the difference from the previously acquired information for the body composition information and the living information at a predetermined timing. For example, the acquisition unit 11 may acquire the difference from the previously acquired body composition information and living information at a predetermined time of day.

[0041] The first calculation unit 13 calculates the tendency of the change in the body evaluation value for each of a plurality of periods. The first calculation unit 13 calculates at least one of whether the body weight is decreasing and whether the body fat mass is decreasing as the tendency of the change.

[0042] The second calculation unit 14 calculates the energy intake of the first user based on the eating and drinking behavior of the first user in each of a plurality of periods. Further, the second calculation unit 14 calculates the energy consumption of the first user based on the exercise behavior of the first user in each of the plurality of periods. The second calculation unit 14 calculates the total energy intake in a third period, which is a continuous period including the first period and the second period, and the total energy consumption in the third period, based on the calculated energy intake and energy consumption of the first user in each period.

[0043] The determination unit 15 calculates the energy balance in the third period based on the total energy intake in the third period and the total energy consumption in the third period. The energy balance is the difference between the total energy intake and the total energy consumption, and is calculated, for example, by subtracting the total energy consumption from the total energy intake. The energy balance is also called the energy balance. The determination unit 15 determines whether the energy balance is less than a reference value. Here, the reference value is determined based on the attribute information of the first user. That is, the reference value is determined to be a different value according to the attribute information of the user.

[0044] The determination unit 15 determines whether the first period is a stagnant period in which it is difficult for the body evaluation value of the first user to improve, based on the first determination result by the first determination unit and the second determination result by the second determination unit. That is, the stagnant period is at least one of a period in which it is difficult for the weight of the first user to decrease compared to the previous period and a period in which it is difficult for the body fat value of the first user to decrease compared to the previous period.

[0045] When the first period is a stagnant period, the notification unit 16 notifies the mobile terminal 20, which is the terminal of the first user, of support information including information indicating that the first period is a stagnant period. The support information includes, for example, information indicating that even if efforts are made to improve lifestyle habits, the current period is a period in which it is difficult for the weight and body fat value of the first user to decrease. As a result, even if the first user is making efforts to improve lifestyle habits, the first user can recognize that it is a stagnant period, so it is easy to maintain motivation for efforts to improve lifestyle habits.

[0046] (Mobile terminal) The mobile terminals 20 and 30 are smartphones, tablet terminals, etc. held by the user.

[0047] The mobile terminal 20 includes a communication unit 21, a reception unit 22, a control unit 23, and a display unit 24. The mobile terminal 30 includes a communication unit 31, a reception unit 32, a control unit 33, and a display unit 34. The communication unit 21, reception unit 22, control unit 23, and display unit 24 included in the mobile terminal 20 are the same as the communication unit 31, reception unit 32, control unit 33, and display unit 34 included in the mobile terminal 30, respectively. For this reason, the configuration of the mobile terminal 20 will be described. The mobile terminals 20 and 30 include a processor and a memory. The functions of the mobile terminals 20 and 30 may be realized by the processor executing a program stored in the memory. In the following, the mobile terminals 20 and 30 may sometimes be referred to as the mobile terminal 20.

[0048] The communication unit 21 exchanges information with the server 10 via the network 40. The communication unit 21 receives support information from the server 10. Also, the communication unit 21 may receive performance information from the server 10. Further, the communication unit 21 may transmit eating information indicating the eating content of the user input by the user to the server 10.

[0049] The reception unit 22 is an input interface (IF) that receives inputs from the first user. The reception unit 22 may receive a selection of a menu of a meal that has been eaten (or will be eaten) from among a plurality of meal menu candidates. The above selection may be made, for example, by the mobile terminal 20 selecting one of the one or more menu candidates included in the UI displayed on the display unit 24 based on an input from the first user to the touch panel provided in the mobile terminal 20.

[0050] When the communication unit 21 receives support information, the control unit 23 displays presentation information based on the received support information on the display unit 24.

[0051] The display unit 24 is a display that displays images and UIs. The display unit 24 displays images and UIs generated by the control unit 23. The display unit 24 is an example of a presentation unit that displays presentation information.

[0052] [Operation] Next, the overall processing flow of the lifestyle improvement system 1 will be described with reference to FIGS. 2 and 3.

[0053] FIG. 2 is a flowchart until a lifestyle improvement proposal tailored to the user is presented.

[0054] In the lifestyle improvement system 1, after the server 10 acquires the user's lifestyle information (such as eating and drinking behavior, exercise behavior, etc.) and biological information (such as body weight, body fat percentage, etc.), it extracts the lifestyle habits that are problems. For the problems, support information (diet improvement and exercise habits) necessary for improvement in view of the lifestyle of the first user is generated and provided to the mobile terminal 20 of the first user, thereby starting the support for improving the lifestyle.

[0055] The server 10 acquires the user's lifestyle information (eating and drinking behavior and exercise behavior) and body composition information (body weight and body fat percentage) from the mobile terminal 20 of the first user (S1). The acquired lifestyle information and body composition information are stored in the storage unit 12 of the server 10.

[0056] Next, the server 10 extracts the lifestyle habits that are issues for the first user based on the acquired body composition information and lifestyle information (S2), and generates support information that helps improve the lifestyle habits of the first user (S3).

[0057] The server 10 notifies the support information to the mobile terminal 20 of the first user (S4).

[0058] Note that the attribute information of the first user is generated based on the information input by the first user to the mobile terminal 20 during the user registration process of the first user. The attribute information of the first user may be transmitted from the mobile terminal 20 to the server 10 and stored in the storage unit 12 of the server 10. Also, information regarding the vital signs of the first user obtained from the results of a health check, etc. may be stored in the storage unit 12 of the server 10.

[0059] FIG. 3 is a flowchart regarding the recording of the implementation status of the user's lifestyle improvement proposal.

[0060] The server 10 acquires the results and progress of the first user's lifestyle improvement actions with respect to the lifestyle improvement proposals presented based on the support information from the lifestyle improvement system 1, and manages the results and progress of the improvement actions.

[0061] The server 10 acquires improvement action information (results of dietary life improvement actions and results of exercise habit improvement actions) indicating the results of improvement actions for the first user based on the lifestyle improvement proposal from the mobile terminal 20 of the first user (S5).

[0062] Next, the server 10 manages the progress of improvement support based on the proposed support information and the acquired improvement action information (S6).

[0063] Next, the server 10 evaluates the content of the acquired improvement action information (dietary life improvement actions and exercise habit improvement actions) based on a specific period (S7).

[0064] Next, the server 10 generates and updates support information for improving lifestyle habits in accordance with the improvement action information and the progress of improvement support (S8).

[0065] Next, the server 10 notifies the mobile terminal 20 of the first user of the support information based on the generated improvement support information (S9).

[0066] FIG. 4 is a diagram showing an example of improvement support information.

[0067] In the storage unit 12 of the server 10, the improvement support information shown in FIG. 4 is stored. The improvement support information stores, for each lifestyle habit item, the lifestyle habit that is a problem and the improvement support measures for improving the lifestyle habit that is a problem. Note that the lifestyle habit that is a problem shows the conditions for determining whether it is a lifestyle habit leading to the user's health problem (for example, obesity). The improvement support information is information for solving the user's health problem corresponding to the lifestyle habit that is a problem.

[0068] The server 10 determines which of a plurality of conditions shown as the lifestyle habits that are problems corresponding to the first user are satisfied based on the lifestyle information and body composition information of the first user, and presents the improvement support information corresponding to the satisfied conditions.

[0069] Note that the lifestyle habits that are problems and the improvement support information in FIG. 4 are merely examples and are not limited thereto.

[0070] FIG. 5 is a flowchart for determining whether there is a stagnation period in the improvement actions of the user within a predetermined period for the improvement support proposal.

[0071] Server 10 acquires lifestyle information (eating and drinking behavior and exercise behavior) and body composition information (weight and body fat percentage). Based on the calculation of energy balance (intake energy / consumption energy) and the evaluation of body composition information (weight and body fat percentage), Server 10 grasps signs of entering a plateau period from the change rates of weight and body fat percentage, and determines whether to enter a plateau period from the energy balance over a predetermined period, based on the judgment criteria (lifestyle improvement criteria) set according to the lifestyle. Server 10 generates (updates) improvement measures during the plateau period as new improvement proposals and presents them to the user.

[0072] Specifically, the acquisition unit 11 of Server 10 acquires the lifestyle information (eating and drinking behavior and exercise behavior) and body composition information (weight and body fat percentage) of the first user from the mobile terminal 20 of the first user (S11). The acquired lifestyle information and body composition information are stored in the storage unit 12.

[0073] Next, the first calculation unit 13 of Server 10 derives from the storage unit 12 the weight and body fat percentage of the first user measured at a plurality of timings based on the body composition information according to a predetermined rule with a specific period as a reference, and determines whether the thresholds of weight and body fat set according to the attribute information of the first user are exceeded (S12).

[0074] Next, the second calculation unit 14 of Server 10 calculates the intake energy of the first user from the eating and drinking behavior and the consumption energy of the first user from the exercise behavior for each of a plurality of periods delimited by a plurality of timings at which the weight and body fat percentage are measured (S13).

[0075] Next, the determination unit 15 of Server 10 determines whether the energy balance in the third period is less than the reference value of the first user (S14).

[0076] Next, the determination unit 15 of the server 10 determines whether the first period is a stagnant period based on the first determination result by the first calculation unit 13 and the second determination result by the determination unit 15 (S15). Specifically, in the first determination result, when the first change rate of the physical evaluation value in the first period is smaller than the second change rate of the physical evaluation value in the second period before the first period, it is shown that the first period is a period in which the physical evaluation value is less likely to decrease than the second period. Also, in the second determination result, when the energy balance is smaller than the reference value, it is shown that the first user is a period in which he / she is working on eating and exercise behaviors so as to improve his / her lifestyle. By using the first determination result and the second determination result, the determination unit 15 can determine whether it is a period (i.e., a stagnant period) in which the physical evaluation value is less likely to decrease than the previous period even though the first user is working on eating and exercise behaviors so as to improve his / her lifestyle.

[0077] When the determination unit 15 of the server 10 determines that it is a stagnant period (Yes in S15), the notification unit 16 of the server 10 generates support information including information indicating that it is a stagnant period (S16), and notifies the mobile terminal 20 of the first user (S17).

[0078] When the determination unit 15 of the server 10 determines that it is not a stagnant period (No in S15), the process ends.

[0079] Next, a part of the process (S13) by the second calculation unit 14 will be described with reference to FIG. 6. FIG. 6 is a flowchart showing an example of the calculation process of the ingested energy.

[0080] The second calculation unit 14 acquires the eating behavior of the first user by referring to the storage unit 12 (S31).

[0081] Next, the second calculation unit 14 determines whether the acquired eating and drinking behavior matches the measurement timing of the body weight and body fat percentage (S32). Here, the measurement timing of the body weight and body fat percentage is, for example, the timing in a fixed time zone or the timing in a predetermined time zone after waking up when the body weight is the lowest during the day. The eating and drinking behavior that matches the measurement timing is the eating and drinking behavior of the first user during a predetermined period in the past based on the measurement timing (that is, the period from the measurement timing to the timing before the predetermined period from the measurement timing).

[0082] If the acquired eating and drinking behavior does not match the measurement timing (No in S32), the second calculation unit 14 ends the process without analyzing the eating and drinking behavior.

[0083] If the acquired eating and drinking behavior matches the measurement timing (Yes in S32), the second calculation unit 14 determines whether the analysis result of the eating and drinking behavior is recorded in the storage unit 12 (S33).

[0084] If the analysis result of the eating and drinking behavior is recorded in the storage unit 12 (Yes in S33), the second calculation unit 14 ends the process without analyzing the eating and drinking behavior.

[0085] If the analysis result of the eating and drinking behavior is not recorded in the storage unit 12 (No in S33), the second calculation unit 14 analyzes the eating and drinking behavior (S34). In the analysis of the eating and drinking behavior, information such as the attributes and intake amounts of food groups is analyzed based on the acquired eating and drinking behavior.

[0086] Based on the analysis result obtained in step S34, the second calculation unit 14 calculates the intake energy (energy intake amount) and nutritional value (S35), and records the calculated intake energy and nutritional value in the storage unit 12 (S36).

[0087] FIG. 7 is a diagram showing an example of the intake energy and nutritional value in eating and drinking behavior.

[0088] The energy intake and nutritional value shown in FIG. 7 are calculated by analyzing dietary information using a food photo. Here, for a recipe, a category (such as main dish, side dish, soup, etc.), genre (Japanese cuisine, Western cuisine, Chinese cuisine, etc.), ingredients (such as pork loin), energy (energy intake), and nutritional value (such as protein) are calculated.

[0089] Next, with reference to FIG. 8, another part of the process (S13) by the second calculation unit 14 will be described. FIG. 8 is a flowchart showing an example of the calculation process of the energy consumption.

[0090] The second calculation unit 14 acquires the exercise behavior of the first user by referring to the storage unit 12 (S41).

[0091] Next, the second calculation unit 14 determines whether the acquired exercise behavior matches the measurement timing of the body weight and body fat percentage (S42). Here, the measurement timing of the body weight and body fat percentage is, for example, the timing in a fixed time zone or the timing in a predetermined time zone after waking up when the body weight is the lowest in a day. The exercise behavior that matches the measurement timing is the exercise behavior of the first user in a predetermined period in the past based on the measurement timing (that is, the period from the measurement timing to the timing before the predetermined period from the measurement timing).

[0092] If the acquired exercise behavior does not match the measurement timing (No in S42), the second calculation unit 14 ends the process without analyzing the exercise behavior.

[0093] If the acquired exercise behavior matches the measurement timing (Yes in S42), the second calculation unit 14 determines whether the analysis result of the exercise behavior is recorded in the storage unit 12 (S43).

[0094] If the analysis result of the exercise behavior is recorded in the storage unit 12 (Yes in S43), the second calculation unit 14 ends the process without analyzing the exercise behavior.

[0095] If the analysis result of the exercise behavior is not recorded in the storage unit 12 (No in S43), the second calculation unit 14 analyzes the exercise behavior (S44). In the analysis of the exercise behavior, based on the acquired exercise behavior and the attribute information (such as age, gender, etc.) of the first user, the energy consumed by the exercise of the first user and the energy consumed at rest in one day are analyzed.

[0096] Based on the analysis result obtained in step S44, the second calculation unit 14 calculates the energy consumption (energy consumption amount) (S45), and records the calculated energy consumption in the storage unit 12 (S46).

[0097] FIG. 9 is a diagram showing an example of the energy consumption in exercise behavior.

[0098] The energy consumption (energy consumption amount) shown in FIG. 9 is calculated by exercise behavior analysis using the exercise record information of the mobile terminal 20. The energy consumption is calculated based on the exercise content, activity intensity, execution time, weight of the subject, etc. for each date.

[0099] FIG. 10 is a diagram showing the basal metabolic rate according to the attribute information of the user.

[0100] Note that the basal metabolic rate indicates the energy consumption at rest in one day.

[0101] The second calculation unit 14 calculates the energy consumption of the first user on a specific day by adding up the energy consumed by the exercise of the first user on the specific day and the basal metabolic rate.

[0102] Note that since there are multiple methods and calculation formulas for calculating the energy consumption, these can be utilized. That is, the energy consumption is not limited to the above method, and may be calculated using another method, or may be calculated using a combined method with another method. When the second calculation unit 14 calculates the energy consumption using multiple methods, the value obtained by integrating the multiple calculation results obtained by multiple methods by averaging or weighted averaging, etc. may be calculated as the energy consumption.

[0103] Next, a part of the determination process (S12) by the first calculation unit 13 will be described with reference to FIG. 11. FIG. 11 is a flowchart showing an example of the analysis process of body weight and body fat percentage.

[0104] The first calculation unit 13 acquires the measurement results of the body weight and body fat percentage of the first user by referring to the storage unit 12 (S51).

[0105] Next, the first calculation unit 13 determines whether or not the acquired measurement result was measured within a predetermined time period recommended by the measurement result (S52). The predetermined time period recommended may be, for example, a time period specified by the user in advance, or may be the time period when the body weight is the lowest during a day. The time period when the body weight is the lowest during a day is, for example, the time period from after waking up until a predetermined time has elapsed.

[0106] If the acquired measurement result was not measured within the predetermined time period (No in S52), the first calculation unit 13 ends the process without analyzing the acquired measurement result.

[0107] If the acquired measurement result was measured within the predetermined time period (Yes in S52), the first calculation unit 13 determines whether or not the analysis result of the measurement result is recorded in the storage unit 12 (S53).

[0108] If the analysis result of the measurement result is recorded in the storage unit 12 (Yes in S53), the first calculation unit 13 ends the process without analyzing the measurement result.

[0109] If the analysis result of the measurement result is not recorded in the storage unit 12 (No in S53), the first calculation unit 13 analyzes the change in body weight based on the measurement result (S54) and analyzes the change in body fat percentage (S55).

[0110] Note that the measurement data of body weight and body fat percentage may be recorded in the mobile terminal 20 of the first user, or may be recorded in a storage area separate from the storage unit 12.

[0111] Next, with reference to FIG. 12, the analysis process (S54) of the weight change by the first calculation unit 13 will be described. FIG. 12 is a flowchart showing an example of the analysis process of the weight change.

[0112] In the analysis process of the weight change, the first calculation unit 13 determines whether the weight is in the decreasing process by using each moving average calculated by the moving average based on the measurement result of the weight.

[0113] The first calculation unit 13 calculates the moving average of the measurement results for a predetermined period (for example, 7 days) (S61). The first calculation unit 13 calculates, for example, the average of the seven weight measurement results obtained daily during the seven days from the first day to the seventh day. On the eighth day, the first calculation unit 13 calculates the average of the seven weight measurement results obtained during the seven days from the second day to the eighth day, and on the ninth day, calculates the average of the seven weight measurement results obtained during the seven days from the third day to the ninth day. In this way, the first calculation unit 13 calculates the average of the seven weight measurement results obtained for each seven-day period that moves one day at a time. The calculated moving average of the weight (moving average weight value) is stored in the storage unit 12.

[0114] FIG. 13 shows specific weight measurement results and analysis results based on the weight measurement results.

[0115] In the calculation of the moving average of the weight in step S61, the first calculation unit 13 calculates, for example, on the 21st day, the average of the seven weight measurement results from the 15th day to the 21st day, and records the calculated moving average of the weight as the moving average weight value on the 21st day. In the example of FIG. 13, the moving average weight value on the 21st day is calculated to be 88.43 kg.

[0116] Next, the first calculation unit 13 calculates a moving average body weight difference, which is the difference from the previously recorded moving average body weight value (S62). For example, the first calculation unit 13 calculates the difference between the moving average body weight value of 88.43 kg calculated on the 21st day and the moving average body weight value of 88.36 kg calculated on the previous 20th day as the moving average body weight difference (+0.07 kg). The difference is calculated by subtracting the measured value at the second timing before the first timing from the measured value at the first timing. The calculated moving average body weight difference is stored in the storage unit 12.

[0117] Next, the first calculation unit 13 evaluates (determines) whether the body weight is decreasing based on the calculated moving average body weight difference (S63). The first calculation unit 13 evaluates (determines) that the body weight is "decreasing" if the moving average body weight difference is a negative value, and evaluates (determines) that the body weight is "not decreasing" if the value is zero or a positive value. Note that the first calculation unit 13 may evaluate that the body weight is "decreasing" when the moving average body weight difference is a negative value, "stagnant" when the value is zero, and "increasing" when the value is a positive value. This evaluation result is recorded as the body weight evaluation result. In the example of FIG. 13, the body weight evaluation result on the 21st day is "increasing".

[0118] Next, the first calculation unit 13 calculates the trend of the body weight based on the body weight evaluation result (S64). In calculating the trend of the body weight, for example, when the body weight evaluation result is "decreasing", the first calculation unit 13 adds 1 to the previously calculated evaluation count value and calculates the added result as the current evaluation count value.

[0119] Next, the first calculation unit 13 determines whether the weight loss has continued for a predetermined period or more by determining whether the evaluation count value is less than the threshold value (S65). For example, when the first calculation unit 13 sets the threshold value of the evaluation count value of the decrease when the predetermined period is 7 days to 5, if the evaluation count value is less than 5 of the threshold value, it is determined that the weight is not in the process of decreasing, the determination result is stored, and the process ends. On the other hand, when the evaluation count value of the decrease when the predetermined period is 7 days is 5 or more of the threshold value, it is determined that the weight is trending downward, the determination result is stored, and the process ends. For example, on the 14th day, it is determined that the weight is trending downward, and on the 21st day, it is determined that the weight is not trending downward.

[0120] Note that as the threshold determination in step S65, in the above case, it is an example set based on the determination of the weight loss behavior. The threshold value may be set to 5, for example, as a value for users with a high intention of improvement behavior, and may be set to 3 as a value for users who feel the need for improvement behavior. In this way, the threshold value may be set to different values according to the strength of the user's intention of improvement behavior.

[0121] Also, as the threshold determination, it may be set based on the determination of specific weight changes. For example, when the BMI of the target user is 25 or more and less than 35, there is a guideline by the Japanese Obesity Society that aims for a decrease of 3% or more from the current weight in 3 to 6 months. Such a threshold value that is the target value of the weight loss rate may be set to 3% in 3 months, 1% in 1 month (4 weeks), and 0.25% in 1 week, for example. When based on the moving average weight at which weight loss started in FIG. 13 (in FIG. 13, the moving average weight on the 7th day), 89.9 kg × 0.25% = 0.22 kg becomes the target for 1 week. Using this as the threshold value, the threshold determination in step S65 may be performed.

[0122] Next, with reference to FIG. 14, the analysis process (S55) of the body fat value change by the first calculation unit 13 will be described. FIG. 14 is a flowchart showing an example of the analysis process of the body fat value change.

[0123] In the analysis process of the body fat value change, the first calculation unit 13 determines whether the body fat value is in a decreasing process (the bioimpedance is in an increasing process) based on the measurement results of the body fat value and using each moving average calculated by the moving average. Here, an example where the body fat value is the bioimpedance will be described. The fact that the body fat percentage is on a decreasing trend indicates that the body water content is in a decreasing process, and the fact that the body fat percentage is on an increasing trend indicates that the body water content is on an increasing trend.

[0124] The first calculation unit 13 calculates the moving average of the measurement results for a predetermined period (for example, 7 days) (S71). The first calculation unit 13 calculates, for example, the average of the measurement results of seven body fat values obtained daily during a 7-day period from the 1st day to the 7th day. On the 8th day, the first calculation unit 13 calculates the average of the measurement results of seven body fat values obtained during a 7-day period from the 2nd day to the 8th day, and on the 9th day, calculates the average of the measurement results of seven body fat values obtained during a 7-day period from the 3rd day to the 9th day. In this way, the first calculation unit 13 calculates the average of the measurement results of seven body fat values obtained for a 7-day period that moves one day at a time. The calculated moving average of the body fat value (moving average body fat value) is stored in the storage unit 12.

[0125] FIG. 15 shows specific measurement results of the body fat value and analysis results based on the measurement results of the body fat value.

[0126] In the calculation of the moving average of the body fat value in step S71, the first calculation unit 13 calculates, for example, on the 21st day, the average of the measurement results of seven body fat values from the 15th day to the 21st day, and records the calculated moving average of the body fat value as the moving average body fat value on the 21st day. In the example of FIG. 15, the moving average body fat value on the 28th day is calculated to be 516.1 Ω.

[0127] Next, the first calculation unit 13 calculates a moving average body fat value difference, which is the difference from the previously recorded moving average body fat value (S72). For example, the first calculation unit 13 calculates the difference between the moving average body fat value of 516.1 Ω calculated on the 28th day and the moving average body fat value of 514.7 Ω calculated on the previous 27th day as the moving average body fat value difference (+1.43 Ω). The difference is calculated by subtracting the measured value at the second timing before the first timing from the measured value at the first timing. The calculated moving average body fat value difference is stored in the storage unit 12.

[0128] Next, the first calculation unit 13 evaluates (determines) whether the body fat value is decreasing based on the calculated moving average body fat value difference (S73). If the moving average body fat value difference is a positive value, the first calculation unit 13 evaluates (determines) that it is "increasing", and if it is zero or a negative value, it evaluates (determines) that it is "not increasing". Note that the first calculation unit 13 may evaluate that it is "increasing" when the moving average body fat value difference is a positive value, "stagnant" when it is zero, and "decreasing" when it is a positive value. This evaluation result is recorded as the body fat value evaluation result. In the example of FIG. 15, the body fat value evaluation result on the 28th day is "increasing".

[0129] Next, the first calculation unit 13 calculates the trend of the body fat value based on the body fat value evaluation result (S74). When calculating the trend of the body fat value, for example, when the body fat value evaluation result is "increasing", the first calculation unit 13 adds 1 to the previously calculated evaluation count value and calculates the added result as the current evaluation count value.

[0130] Next, the first calculation unit 13 determines whether the increase in the body fat value has continued for a predetermined period or more by determining whether the evaluation count value is less than the threshold value (S75). For example, when the threshold value of the evaluation count value for decrease is set to 5 assuming a predetermined period of 7 days, if the evaluation count value is less than 5, the first calculation unit 13 determines that the body fat value is not in the increasing process, stores the determination result, and ends the process. On the other hand, when the evaluation count value for increase is 5 or more assuming a predetermined period of 7 days, the first calculation unit 13 determines that the body fat value is on an increasing trend, stores the determination result, and ends the process. For example, on the 14th day, it is determined that the body fat value is on an increasing trend, and on the 21st day, it is determined that the body fat value is not on an increasing trend.

[0131] Note that, as the threshold determination in step S75, in the above case, it is an example set based on the determination of the body fat reduction behavior. The threshold value may be set to 5, for example, as a value for users with a high intention of improvement behavior, and may be set to 3 as a value for users who feel the need for improvement behavior. In this way, the threshold value may be set to different values according to the strength of the user's intention of improvement behavior.

[0132] Also, as the threshold determination, it may be set based on the determination of specific body fat value changes. For example, the threshold value as the target value of the increase rate of the body fat value may be set to 8% in one month and 2% in one week, for example. When based on the moving average body fat value (the moving average body fat value on the 7th day in FIG. 15) at which the reduction of body fat (increase in bioimpedance) starts in FIG. 15, an increase of 494.7 Ω × 2% = 9.89 Ω becomes the target for one week. Using this as the threshold value, the threshold determination in step S75 may be performed.

[0133] Next, with reference to FIGS. 16 and 17, the transition state determination process (S15: third determination) by the determination unit 15 will be described.

[0134] The determination unit 15 evaluates (determines) the improvement actions of the first user within a predetermined period, and determines whether the first user is in a stagnant period at present (the first period). Based on the improvement action information of the first user on the life improvement proposals presented from the lifestyle improvement system 1, and taking into account that the actions are being performed correctly, the determination unit 15 determines the transition state based on the determination results based on the intake energy, the consumption energy, the body weight, and the body fat value. By determining the transition state, it is determined whether the first period (the most recent period) to be determined is a stagnant period.

[0135] The determination unit 15 evaluates the improvement actions of the first user with respect to a specific period as a reference, and evaluates the content of the acquired improvement action information (diet improvement and exercise habit improvement) (S81). The determination unit 15 evaluates, for example, whether the improvement proposals regarding diet and exercise habits can be executed.

[0136] If the determination unit 15 cannot execute the improvement proposal correctly (No in S82), it ends the process without determining the transition state.

[0137] If the determination unit 15 can execute the improvement proposal correctly (Yes in S82), it analyzes the energy management evaluation results including the intake energy, the nutritional value, and the consumption energy for a predetermined period (S83).

[0138] FIG. 18 is an example showing the relationship between the intake energy and the consumption energy.

[0139] For example, when the intake energy is 2000 kcal or less and the consumption energy (including basal metabolism) is 2000 kcal, if the daily energy balance (energy difference) is zero or less within a predetermined period, it can be evaluated that the management is being performed correctly.

[0140] Note that the evaluation method for evaluating whether it can be executed correctly is not limited to the above, and it may be determined by a moving average, a slope calculation, or the like.

[0141] In addition, regarding nutritional value, it may be determined whether excessive weight loss or a diet that impairs health is being followed. This determination may be made, for example, by comparing nutritional values based on target values determined with reference to dietary intake standards for Japanese people or the like. If these target values are not met, the guidance method is updated (generated) in the improvement support information so as to meet the target values.

[0142] Next, the determination unit 15 analyzes the biometric information management evaluation results regarding weight management and body fat value management over a predetermined period (S84).

[0143] FIG. 19 is a graph showing an example of the results of the biometric information evaluation unit (weight change analysis, body fat change analysis).

[0144] For example, at A (the 14th day), the weight decreases and the body fat information (impedance) shows an increasing trend, and it is determined that weight loss is proceeding smoothly.

[0145] Next, at B (the 21st day), the weight changes from decreasing to stagnating, and the body fat information turns to decreasing. At this point, if there are no problems with the improvement actions and energy management, it is determined that the body has entered a stagnation period.

[0146] Next, at C (the 28th day), the weight stagnates and the body fat information changes from stagnating to increasing. At this point as well, if there are no problems with the improvement actions and energy management, it is determined that the body is emerging from the stagnation period.

[0147] Finally, at D (the 35th day), since the weight is decreasing and the body fat information is also increasing, it is determined that weight loss is proceeding smoothly.

[0148] The determination unit 15 performs a transition state evaluation based on the above results (S85).

[0149] FIG. 20 is a diagram showing an example of the transition state evaluation results.

[0150] For example, if a person has made improvement suggestions and is able to manage energy, but their weight has stopped decreasing and started to stagnate, and their body fat information is showing a decreasing trend, it is evaluated that "they may be entering a plateau period", and the evaluation result is output.

[0151] For example, if a person has made improvement suggestions and is still able to continue managing energy, their weight is in a stagnant state, but their body fat value is showing an increasing trend from stagnation, it is evaluated that "they may be ending the plateau period", and the evaluation result is output.

[0152] In this way, the intake energy, consumption energy, moving average weight value, and moving average body fat value for a predetermined period are calculated, and based on the calculated variation difference, the transition state of the subject is determined.

[0153] Upon receiving the determination result from the determination unit 15, when there is a possibility of entering a plateau period (or a possibility of ending the plateau period), the notification unit 16 notifies the user of the result, and in order to prevent the first user from disengaging from the improvement actions of their lifestyle habits, it may also generate and present different improvement support information with an equivalent effect.

[0154] For example, as shown in the lower part of FIG. 20, when it is determined that there is a possibility of entering a plateau period, not only is this fact notified, but also, for example, a change to an improvement suggestion that emphasizes improving basal metabolism, which is a common countermeasure for the plateau period, may be proposed. For example, for exercise, a proposal for exercise that leads to increased muscle strength may be made, and for diet, a proposal for protein intake (specific ingredients, how to eat lunch, recommended dinner recipes, etc., proposals that are feasible according to the user's lifestyle pattern may be made.

[0155] In addition, in the generation of improvement support information from the transition state determination, for example, from various information of other users similar to the user's attribute information (such as age, gender, occupation, lifestyle pattern, etc.), it is also conceivable to refer to and generate the possibility of entering a plateau period, the possibility of ending the plateau period, and the improvement measures information generated at that time.

[0156] That is, the storage unit 12 may store, for each of a plurality of other users (a plurality of second users) other than the first user, whose physical evaluation values have been improved after a stagnant period, body composition information, intake energy, and consumption energy during a consecutive fourth period after the stagnant period of the corresponding second user. The storage unit 12 may further store attribute information of each of the plurality of second users. When the first period is a stagnant period, the notification unit 16 refers to the storage unit 12 to identify at least one second user having attribute information similar to the attribute information of the first user among the plurality of second users. Then, the notification unit 16 may generate support information further including the body composition information, intake energy, and consumption energy of the identified at least one second user during the stagnant period, and notify the generated support information to the mobile terminal of the first user.

[0157] [Effects, etc.] According to the lifestyle improvement system 1 according to the present embodiment, based on the trend of change in the physical evaluation value, intake energy, and consumption energy, it is possible to determine whether the first period is a stagnant period, and notify the first user of information including the determination result. Therefore, the first user can recognize whether the state of the first user is a stagnant period, and it is possible to suppress the decrease in the motivation to improve the lifestyle. Thus, it is possible to effectively support the improvement of the lifestyle of the first user.

[0158] [Others] In addition, in the above embodiment and its modifications, each component may be configured by dedicated hardware or may be realized by executing a software program suitable for each component. Each component may be realized by a program execution unit such as a CPU or a processor reading and executing a software program recorded on a recording medium such as a hard disk or a semiconductor memory.
