Description

  The present invention relates to a calorie calculation device, a calorie calculation method, and a program.

  2. Description of the Related Art In recent years, a calorie calculation device that calculates the amount of energy consumed by a meal has been proposed for the purpose of weight management due to an increase in health consciousness. As an example of such a calorie calculating device, for example, as disclosed in Patent Document 1, when each kind of food to be eaten and its amount are input, the intake of each food is automatically performed based on this. A calorie calculator is known in which calories are calculated and accumulated to calculate and display today's intake calories. Further, the calorie calculator is configured to sound a warning chime to notify that the calorie intake is excessive if the calorie intake today is greater than the standard calorie intake determined based on the standard weight determined from the height of the user.

JP-A-9-179830

However, in the above-described conventional calorie calculation device (calorie calculator), the user must input the type and amount of each food to be eaten. In other words, the input of the type of food (food name) is performed by selecting from candidates prepared in advance, but it is necessary to search for a desired food name from a large number of candidates while switching the screen. Moreover, although the quantity of food is input by operating the number keys, the quantity must be grasped by itself. Furthermore, this type and quantity input operation must be performed for every food item for each meal every day. In addition, diet management for the purpose of weight management needs to be performed over a long period of time.
Such annoying meal input is a major factor that is not practical for continuous use and does not last long.

[Overview]
An outline of calorie intake calculation in the calorie calculation apparatus 1000 will be described with reference to a display screen of the liquid crystal display 1006.

(1) Initial Setting First, for example, initial setting is performed on the initial setting screen 10 shown in FIG. FIG. 2 is a diagram illustrating an example of the initial setting screen 10. As shown in FIG. 2, the initial setting screen 10 is provided with input items for the current weight (initial weight (reference weight)), physical activity level, age, sex, and intake calorie management start date (reference date). ing. The physical activity level represents the degree of daily exercise amount, and is selected from four levels 1 to 4 determined in advance according to the difference in exercise amount. When all items are entered, the target weight calculated from the initial weight is displayed.

(2) Meal input When the initial setting is completed, the amount of meal on that day (the day) is input every day from the set management start date, for example, on the meal input screen 20 shown in FIG. FIG. 3 is a diagram illustrating an example of the meal input screen 20. The meal input screen 20 is a screen for inputting the amount of meals of the day (today), and is provided with input items for the weight of the day and the amount of meals of each meal. There are four types of meal types: “morning”, “noon”, “evening”, and “others”. The amount of meal is the subjective amount of meal that the user has determined to be “about this amount of meal”, and there are four choices of “large”, “normal”, “small” and “none (not eating)” Select from. When all items are entered and “input complete” is selected, a calorie intake screen 30 shown as an example in FIG. 4 is displayed.

(3) Calculation of Intake Calories FIG. 4 is a diagram illustrating an example of the intake calorie screen 30. On the intake calorie screen 30, the intake calories for one day of each day from the start date to today are displayed in time series in a bar graph format. In addition, the calorie intake for one day is a stacked bar graph showing the breakdown of the calorie intake of each meal of “morning”, “noon”, “evening”, and “others”. The calorie intake displayed here is a value calculated (estimated) from the meal amount for each meal input on the meal input screen 20. In addition, in this graph, a “target calorie intake range” defined as a target of daily calorie intake is displayed in an overlapping manner. Depending on whether or not the daily calorie intake is within this “target calorie intake range”, it can be used as a standard for determining whether or not the daily amount of meal is appropriate. The calorie intake displayed here is an estimated value.

[principle]
Next, a method for calculating calorie intake according to this embodiment will be described. In the present embodiment, “calorie intake” is calculated using the calculation formula (1) of “amount of energy required per day (necessary calorie intake)” presented by the Ministry of Health, Labor and Welfare.
Weight W x Basal metabolism reference value B x Activity coefficient (1)

(1) Initial setting First, the initial setting based on the input content (initial weight, physical activity level, sex and age) on the initial setting screen 10 is performed. Specifically, the target weight W1 is set from the initial weight W0 of the user. The target weight W1 is given by the following equation (2).
Target weight W1 = initial weight W0 × (1-m) (2)

  In Expression (2), “m” is a weight loss ratio with respect to the initial weight W0, and is a value of 0 or more and less than 1. In the present embodiment, the fixed value is “m = 0.06 (6%)”, but the user may select from a predetermined range (for example, 2 to 10%).

Next, a target intake calorie range is set from the target weight W1. The target intake calorie range is given by the following equation (3).
Target intake calorie range = target weight W1 × first activity coefficient K1 (3)

  In Expression (3), the “first activity coefficient K1” is a calorie necessary per 1 kg of body weight, and is determined by the physical activity level of the user. For example, it is determined as shown in FIG. FIG. 5 is a diagram illustrating an example of a data configuration of the first activity coefficient table 340. According to FIG. 5, the first activity coefficient table 340 stores the physical activity level 341 in association with the lower limit and the upper limit of the first activity coefficient 342. In the first activity coefficient table 340, the higher the activity level, that is, the greater the amount of daily physical activity, the more calories are consumed, so the first activity coefficient is determined to be larger. Moreover, the upper limit and the lower limit of the first activity coefficient are determined such that the target calorie intake range includes the calorie intake necessary for one day calculated from the above-described equation (1).

(2) Calorie calculation When the initial setting is completed, the “calorie intake Cn for each meal” is calculated based on the daily meal amount input on the meal input screen 20. The calorie intake Cn for each meal is given by the following formula (4).
Calorie intake by meal Cn = weight W2 of the day × basal metabolism reference value B × second activity coefficient K2
X Meal coefficient Xn-Correction value Yn (4)

The daily intake calorie Cd is the sum of the intake calorie Cn for each meal as given by the following equation (5).
Daily calorie intake Cd = C1 + C2 + C3 + C4 (5)

  In the formula (4), the “basal metabolism reference value B” is determined by gender and age, and is determined as shown in FIG. 6, for example. FIG. 6 is a diagram illustrating an example of a data configuration of the basal metabolism reference value table 330. According to FIG. 6, the basal metabolism reference value table 330 stores a basal metabolism reference value 333 in association with each combination of gender 331 and age 332.

  In Expression (4), the “second activity coefficient K2” is determined by the amount of physical activity of the user, and is determined as shown in FIG. 7, for example. FIG. 7 is a diagram illustrating an example of a data configuration of the second activity coefficient table 350. According to FIG. 7, the second activity coefficient table 350 stores the second activity coefficient 352 in association with each physical activity level 351. In the second activity coefficient table 350, the higher the physical activity level, that is, the greater the amount of daily physical activity, the more calories are consumed, so the second activity coefficient is determined to be larger.

  In the formula (4), the “meal coefficient Xn” is determined by the amount of meals of the user (large, normal, small, not eating), and is determined as shown in FIG. 8, for example. FIG. 8 is a diagram illustrating an example of a data configuration of the meal coefficient table 360. According to FIG. 8, the meal coefficient table 360 stores the meal coefficient 362 of each meal in association with each meal quantity 361. In the meal coefficient table 360, since the calorie intake is higher as the meal amount is larger, the meal coefficient Xn is determined to be larger. This meal coefficient Xn is a value determined from past surveys. Specifically, for each of a plurality of subjects, the actual calorie intake determined by recording the meal content and the user at that time This is set by investigating the amount of meals (large, normal, and small) that you thought in step 1, and determining the relationship between the subjective amount of meal and the actual calorie intake.

In the equation (4), the “correction value Yn” is a value for correcting the change in the relationship between the user's subjective meal amount and the actual calorie intake accompanying the change in weight, and is given by the following equation (6). It is done.
Correction value Yn = correction calorie Y × Xn / (X1 + X2 + X3 + X4) (6)
Correction calorie Y = ((the current body weight W2−initial body weight W0) × 7000 [kcal])
/Number of days elapsed

  In Formula (6), “7000 [kcal]” is a calorie necessary for reducing the weight by “1 kg”. “Elapsed days” is the number of days elapsed from the start date to today. That is, the “corrected calorie Y” is a value obtained by dividing the calorie corresponding to the increase / decrease ΔW of the daily weight (today's weight) W2 with respect to the initial weight W0 by the number of days elapsed from the start date to today. It is a change equivalent calorie. The correction value Yn for each meal is a value obtained by distributing the corrected calorie Y according to the meal coefficient Xn corresponding to the meal amount.

The principle of setting the “correction value Y” will be described. In this embodiment, the dietary calorie intake Cn is calculated by the above equation (4), but consider the case where the correction value Y is not considered.
In this case, there is a disadvantage that the calculated calorie intake by meal hardly changes (does not decrease) in spite of the fact that the body weight decreases with a decrease in the actual meal amount (calorie intake). This is a user's subjective amount that “meal amount” in this embodiment is “large, normal, small” and is not an actual meal amount (calorie intake), which is a disadvantage that may occur.

  FIG. 9 is a diagram illustrating an example of a change in calorie intake accompanying a change (decrease) in body weight. In the figure, if the initial weight W0 is “100 kg”, the target weight W1 is “94 kg”, and the target calorie intake range is “2350-2820 kcal”. Then, it is assumed that the weight W2 of today decreases to “95 kg”, which is substantially the target weight W1, after 50 days have passed in a state where the amount of each meal is “normal”.

  In this case, the calorie intake at “100 kg” that is the initial weight W0 is “3345 kg”, which is larger than the target calorie intake range. The calorie intake at “95 kg”, which is the weight W2 of today's weight after the weight reduction, is “3178 kcal” when the correction value Y is not used (no correction). This is almost the same as the calorie intake at the initial weight W0 and is greater than the target calorie intake range. On the other hand, in the case of using the correction value Y (with correction), it becomes “2548 kcal”, which is within the target calorie intake range.

  Thus, even if the user thinks that there is no change in his / her “meal amount”, a state in which the weight W is decreased can occur due to a decrease in the actual meal amount (calorie intake). That is, a difference occurs between the user's subjective “meal amount” and the actual “meal amount (calorie intake)”, and this difference changes with changes in body weight.

  Further, according to the formula (1), “calorie intake necessary for one day” decreases as the body weight decreases. That is, even if the “meal amount” is the same, if the weight W is different, the “calorie intake necessary for one day” is different. For this reason, in this embodiment, the correction value Y for correcting the calculation error of the calorie intake is defined using the weight change ΔW from the initial weight W0 (= the daily weight W2−the initial weight W0). .

[Process flow]
FIG. 13 is a flowchart for explaining the flow of intake calorie management processing. According to FIG. 13, first, the user management unit 210 performs login processing for authenticating whether a user is a registered user by inputting a user ID and a password (step S1). If it is not authenticated as a result of the login process (step S3: NO), a process of registering as a new user is performed. That is, a user name and password are set (step S5). Next, the initial setting screen (see FIG. 2) is displayed, and the initial weight, activity level, age and gender, etc. are input (step S7). Subsequently, the target weight is calculated / set from the input initial weight (step S9), and the target intake calorie range is calculated / set from the target weight and the activity level (step S11).

  On the other hand, if authenticated (step S3: YES) or the user registration is completed, then the meal amount input management unit 220 displays a meal input screen (see FIG. 3) to determine the current weight. While inputting (step S13), the amount of each day's meal is input (step S15).

  And if the meal amount of each meal of today is input (step S17: YES), the calorie intake of today will be calculated. That is, first, the correction value determination unit 230 calculates today's correction calorie Y (step S19), and calculates a correction value Yn for each meal (step S21). Subsequently, the calorie calculation unit 240 calculates the intake calorie Cn for each meal for each meal (step S23), and calculates the daily intake calorie Cd for today, which is the sum of these (step S25).

  Then, the alerting | reporting part 250 displays the intake calorie screen (refer FIG. 4) which displayed the intake calorie for every day (step S27). When the logout process is performed (step S29), the intake calorie management process ends.

[Action / Effect]
Thus, according to the calorie calculation apparatus 1000 of the present embodiment, when the user inputs the weight W2 of the day and the subjective meal amount of each meal of the day, the calorie intake of each meal is calculated (estimated). The In other words, for the user, the amount of meal to be input is simply the content of the subjective amount of meal to be considered by the user (for example, “large”, “normal”, “small”, etc.). Compared to the conventional method of inputting, the labor of inputting is remarkably reduced.

  Also, a target intake calorie range for setting the target weight W1 determined from the initial weight W0 is determined. The calculated calorie intake is displayed in a graph together with the target calorie intake range. Thereby, in order to reduce the weight to the target weight W1, the user can be given a criterion for determining whether or not the current meal amount is appropriate.

  Further, by using the correction value Y in calculating the calorie intake Cn by meal, a calculation error caused by the difference between the user's subjective “meal amount” and the actual “meal amount (calorie intake)” associated with the change in body weight. Can be corrected.

Specifically, first, a target past date is designated, and the weight W2 of that day and the amount of each meal are input. And the calorie intake of the day is calculated about the day when the weight W and the meal amount of each meal were all input.

(3)
In the above-described embodiment, the daily meal amount is input every day. However, it is not necessary to input the daily meal amount, and it is also possible to input the daily meal amount.

(4)
In the above-described embodiment, a smart phone is used as an example of the calorie calculation device 1000. However, the present invention is not limited to this as long as the electronic device has a built-in computer and can execute an application program. For example, a personal computer, a mobile phone, a music player, etc. can be used.
