Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a diet simulation apparatus capable of recognizing an appropriate diet method and a difference between a diet target value and a current value with a real feeling by simulating a diet.

[0002]

2. Description of the Related Art Conventionally, when trying to diet, a body fat meter or the like measures body fat percentage, body fat mass, lean mass, etc., and a standard presented according to the characteristics of the user. While referring to information such as the degree of obesity indicating the degree of deviation between the measured value or the standard value and the measured value, the dietary content is considered or exercise is performed.

[0003]

However, it is possible to vaguely recognize the necessity of dieting only from information such as the numerical value of the body fat percentage and the index of the obesity degree, etc. For programs such as what kind of exercise and how much exercise should be performed, there was annoyance that the user had to receive advice from an expert or the user himself had to refer to the literature etc. It was not enough to actually impress the need for diet with a real feeling.

[0004] Even if an appropriate program including a meal menu and an exercise menu is given, how much body fat actually accumulates when what kind of meal is eaten, and how much exercise and how much exercise is done It was difficult to grasp how much the measured body fat decreased with a real feeling from the transition of the numerical values and the index. For this reason, it was difficult to continue the program execution until a specific result appeared.

The present invention has been made in order to solve the problems of the prior art, and an object of the present invention is to recognize a diet effect and an appropriate diet method by simulating a diet. Along with
It is an object of the present invention to provide a diet simulation device that enables healthy and enjoyable health management.

[0006]

In order to achieve the above object, a first aspect of the present invention includes a characteristic index obtaining unit for obtaining a characteristic index value indicating a physical characteristic of a subject, and at least a content of eating. Condition setting means for setting a condition, the characteristic index value acquired by the characteristic index acquisition means, and a change in the physical state of the subject based on the condition set by each condition setting means. A diet simulation apparatus for simulating, wherein at least one of the conditions is a work performance dependent condition that changes a setting content according to a work performance when the subject performs a predetermined work. It is characterized by the following.

[0007] The diet is intended to reduce obesity, maintain lean body mass, strengthen muscles, improve various symptoms, etc., and take into account the contents of the diet, including the menu and how to take it. Means However, in order to achieve such an object, it is desirable to exercise not only in consideration of meals. Therefore, in order to simulate a change in the body condition during a diet, it is necessary to set various conditions including the contents of eating and exercise, and simulate the change in the body condition under such conditions (hereinafter, referred to as “diet”). ,
Where appropriate, “diet” is used not only to include consideration for diet, but also to include activities such as exercises that should accompany it. ). Here, the content of eating may be set as a specific combination of food and drink, may be set in terms of energy, may be set by dissolving into components such as nutrients, and may be set according to a simulation. It should be set with.
In the case of dieting, it is general to exercise or the like after eating some kind of food. However, actually, exercise or the like may be performed without eating anything. In response to such a case, there is no eating content or the energy intake is zero.
May be set as the condition.

[0008] In addition, since the effects of diet and exercise vary from person to person, it is necessary to incorporate an index value indicating the physical characteristics of an individual in order to simulate a change in physical condition during a diet. Characteristic indices indicating physical characteristics include not only height, weight, age, and sex, but also indices indicating body composition such as body fat percentage, body fat mass, lean mass, and physiological characteristics such as blood pressure, pulse, and blood sugar level. Like an index indicating a state, an index of the characteristics of the body from various aspects can be used. These physical characteristic indices may be set by directly inputting them from input means such as a keyboard, or may be obtained by measuring using a measuring means.

In the simulation of the change in the physical condition, an index that fluctuates reflecting the physiological activity of the body is selected, a model for reproducing the change in the physical condition under the above-mentioned preconditions is set, and the index value is set. The above-mentioned index value of the physical condition at the time of realizing the precondition is calculated by setting an arithmetic expression that defines the behavior of the above. Such a simulation can be realized by executing a predetermined simulation program on a computer including an arithmetic processing unit such as a CPU, a storage unit such as a memory, and an input unit such as a keyboard. As an index that fluctuates reflecting such a physiological state, not only the weight but also an energy balance related to body fat accumulation may be used, and when improving a symptom, a blood glucose level or the like which is a guide of the symptom may be used. Any physiological index may be used as long as it indicates a physical condition.

When a simulation is performed by setting the above-mentioned characteristic index values and conditions, if at least one of the setting contents is changed according to the work performance when the subject performs a predetermined work, Simulation results also differ depending on work results. Therefore, it is possible to know the effect of the diet and the appropriate dieting method while enjoying the work, so that the health management can be continuously performed without any hesitation.

[0011] Further, since the diet itself involves an active act such as eating or exercising, by replacing the act at the time of such a diet with another work and experiencing it in a simulated manner, the sense of realism increases and By changing the setting contents according to the work performance, the user can enjoy the feeling of accomplishment of the diet, the difficulty of the diet, and the like more through the work, and can continuously perform health management without hesitation.

In the present invention, in order to perform a more appropriate simulation, a characteristic index value indicating the physical characteristics of the subject is also acquired. However, without acquiring such a characteristic index, general conditions are determined in advance. The simulation may be performed by setting only the conditions such as meals and exercise.

The setting of the condition including at least the content of eating is not limited to the case where the subject sets the condition by selection, input, etc., but the apparatus side sets a predetermined condition in advance. Is also good.

According to a second aspect, in the first aspect, a characteristic target acquiring means for acquiring a target value of the characteristic index, and an evaluating means for evaluating a simulation result based on the target value of the characteristic index. And characterized in that:

The target value of the characteristic index may be set by the subject, or a standard value may be calculated from other characteristic information and set as the target value.

If the evaluation means is provided, it is evaluated whether or not a target value can be realized under the set conditions with respect to the simulation result under the set conditions, or how much the result is different from the target value. be able to. In other words, it is possible to gain motivation for the diet through understanding of whether the goal can be achieved with the diet of the set content or what content can be achieved by setting the content,
With fun and real feeling, it is possible to gain an understanding of the effect of the diet and an appropriate dieting method.

In a third aspect based on the first or second aspect, the work performance dependent condition is a predetermined amount of exercise, and the work of the subject is performed in accordance with a predetermined program according to the operation of the subject. And the progress of the exercise is controlled, and the degree of achievement of the exercise changes according to the performance of the game.

The exercise associated with diet is important but involves difficulty in execution and continuation, and it is also difficult to achieve a target exercise amount. Such a movement is replaced with a game in which the progress is controlled according to the operation of the target person in accordance with a predetermined program, and a simulated experience is provided. In addition, by changing the degree of exercise achievement according to the result of the game, it is possible to enjoy the feeling of accomplishment of the diet, the difficulty of the diet, etc. with a more real feeling, and to manage the health happily in a fun and game-like manner.

When a predetermined amount of exercise, which is a work-dependent condition, is set, a specific type of exercise and an execution time may be set, or energy consumption per unit time and an execution time may be set. You may. At this time, the setting of the predetermined exercise does not necessarily need to be based on the combination of the type of exercise and the execution time. For example, jogging and distance, abdominal muscles and the number of times may be used, and the exercise may be set to specify the amount of exercise. For example, when a predetermined amount of exercise is set based on the type of exercise and the execution time, the setting content of the game is set such that only the execution time set by the condition setting means corresponding to the degree of achievement has been executed. Change according to your grades,
Simulate based on changed conditions. As described above, when the predetermined amount of exercise includes the type of exercise (fixed item) and the execution time (variable item), the variable item may be changed according to the degree of achievement.

In a fourth aspect based on the first aspect, a characteristic target acquiring means for acquiring a target value of the characteristic index, and an evaluating means for evaluating a simulation result based on the target value of the characteristic index. And the work performance dependent condition is a predetermined amount of exercise, the work of the subject,
A game in which the progress is controlled in accordance with an operation of the target person in accordance with a predetermined program, wherein the degree of achievement of the exercise is changed in accordance with the performance of the game, and the game is executed in accordance with the evaluation result by the evaluation means. It is characterized by controlling the progress.

The progress of the game is controlled according to the evaluation result of the evaluation means such as the feasibility of the target value under the above conditions and the deviation between the executed result and the target value. For example, when the target is achieved, the game is played. If you end the game and do not end the game if it deviates from the target value, the suitability of the set conditions will be reflected in the progress of the game, so you will have a fun understanding of the effects of diet and the appropriate diet method through the game be able to.

According to a fifth aspect based on the third or fourth aspect, the difficulty of the game is controlled in accordance with the type of the exercise.

As described above, the difficulty level of the game is controlled in accordance with the type of the exercise. For example, if the exercise has a large exercise intensity such that the energy consumption per unit time is large, the game progress becomes difficult and the unit time is increased. If the exercise intensity is small, such as low energy consumption per hit, if the game progress is made easier, the sense of realism will increase and the feeling of achievement and difficulty of diet can be enjoyed with more realism. Health management can be carried out continuously without being delighted.

In a sixth aspect based on the third to fifth aspects, the operation information input means for inputting the operation information of the game by the target person includes a motion state of the target person during a predetermined operation. It is characterized in that it is detected and converted into operation information.

As described above, if the operation information input means of the game detects the exercise state of the target person at the time of a predetermined operation and converts it into operation information, it is possible to simply turn on or off a button or switch.
Since motions involving various exercises can be used for inputting operation information of the game instead of OFF, it is possible to replace the exercise at the time of dieting with the operation at the time of the game operation and experience a simulated experience. In addition, it is possible to enjoy the feeling of achievement and difficulty of dieting with more real feeling, and to be able to continuously manage health without being delighted.

According to a seventh aspect based on the sixth aspect, the operation information input means detects the exercise state based on a change in body impedance.

The body impedance can be measured by detecting a resistance potential generated by a current applied to the body. Since the body impedance measurement value fluctuates by bending and stretching the joints on the current supply path of the applied current and expanding and contracting the muscles, set the current supply path for the applied current including the joints that bend and extend and the muscles that expand and contract during a predetermined operation. For example, the exercise state at the time of the predetermined operation can be easily detected by the change in the body impedance.

Measurement of such body impedance is as follows.
This is performed by detecting a resistance potential by two electrodes arranged on a current path of a current applied by two electrodes brought into contact with the body. Although the application of the current and the detection of the resistance potential may be performed by the same electrode, the detection of the resistance potential may be performed by an electrode insulated from the electrode to which the current is applied.

According to an eighth aspect, in the sixth or seventh aspect, a load means for applying a load to the predetermined operation is provided.

If a load is applied to a predetermined operation, a movement against the load is required for the operation of the game. Therefore, not only a simulation but also an actual exercise effect is obtained, and the sense of realism is further increased.

A ninth invention is characterized in that, in the eighth invention, a load amount setting means for setting a load amount given by the load means is provided, and the progress of the game is controlled by the load amount.

If the progress of the game is controlled by the set load amount, the actual movement at the time of the game operation can be reflected on the progress of the game, and the sense of realism is further increased.

In a tenth aspect based on the first to ninth aspects, the characteristic index is body composition information of the subject, and the characteristic index obtaining means is an impedance measuring means for measuring the body impedance of the subject. And a converting means for converting the measured body impedance value measured by the impedance measuring means into the body composition information.

In general, what matters in a diet is not simply weight but body composition information such as a body fat percentage and a body fat amount indicating how much body fat is accumulated. By acquiring characteristic indicators,
More accurate simulation can be performed. In addition, since the body fat percentage can be calculated from the body impedance measurement value and information such as height, weight, age, and gender, it is possible to easily obtain these body composition information by measuring the body impedance. it can.

According to an eleventh aspect, in the first to tenth aspects, an energy balance is simulated as the change in the physical condition.

In general, body fat is caused by the energy taken in by meals being accumulated without being sufficiently consumed by exercise or the like. Therefore, if the energy balance is simulated as a change in body state, the body fat is consumed. A simulation that accurately reflects the problematic change in body fat becomes possible.

Next, the subject inputs body-specific information such as height, weight, age, and gender in accordance with a procedure described later (step 2).

It is determined whether the input of the body specifying information has been completed (READY?) (Step 3).
If it is o, the process returns to step 2 and waits until the input is completed.
If es, a message such as "READY" is displayed on the display unit 3 to notify the subject of the completion of the input (step 4),

First, it is determined whether or not it is a predetermined sampling timing (for example, 0.1 sec) (step 10).
1).

If Yes in step 101, impedance measurement is performed (step 102), and the measured
It is stored in a predetermined area of M28 (step 103), and the process proceeds to step 104.

If No in step 101, or after storing the measured value in the RAM 28 in step 103, it is determined whether the body specification information setting mode is the height setting mode (step 104). At this time, the initial setting is made so that the height setting mode is set, and the setting is completed so that the weight, age, and gender can be set in this order each time the setting is completed, but the setting order is limited to this. Absent. The determination of the setting mode can be made based on whether or not a predetermined flag is set.

If Yes in step 104, the process proceeds to step 109. If No in step 104, it is determined whether the body specifying information setting mode is the weight mode (step 105).

If Yes in step 105, the process proceeds to step 109. If No in step 105, it is determined whether the body specifying information setting mode is the age setting mode or not (step 106).

If Yes in step 106, the process proceeds to step 109. If No in step 106, it is determined whether the body specifying information setting mode is the gender setting mode (step 107).

If Yes in step 107, the process proceeds to step 109. If No in step 107, it is determined whether setting of all the setting items of the body specifying information has been completed (step 108).

In step 109, input selection / setting processing is performed in accordance with the procedure described later, and the selected setting mode, set value, and the like are displayed on the display unit 3 (step 110), and the flow advances to step 110.

At step 108, it is determined whether or not setting of all setting items has been completed. If Yes, the READY flag is set to, for example, "1" (step 111).
If it is o, the setting of the READY flag is canceled (step 112), and the process returns to the main routine of FIG.

(Input Selection / Setting Processing Subroutine) Hereinafter, step 1 of FIG.
The procedure of the input selection / setting process 09 will be described.

First, the setting mode is recognized by a flag or the like (step 201), and the input selection and / or input setting of the setting item is performed in the following procedure.

In step 202, in step 104, R
The measured impedance value stored in a predetermined area of the AM 28 is read. If the determination in step 101 is No and the impedance measurement value is not stored in the memory, the process may return to step 101 without reading.

Next, the control switch 12 on the right palm side
Is determined whether or not is ON (step 203). If Yes, the set value is determined (step 204), and input selection /
The setting process ends, and the process returns to the body specific information input subroutine of FIG.

If No in step 203, it is further determined whether or not the control switch 11 on the left palm side is ON (step 205). If Yes, the setting mode is changed and shifted to the next setting mode. (Step 206),
It returns to the body specific information input subroutine of FIG.

If No in step 205, it is determined whether or not the impedance measurement value between both palms read in step 202 is within the normal measurement range (for example, 340 to 1200Ω) (step 207).

If No in step 207, the input selection / setting process ends, and the process returns to the body specifying information input subroutine of FIG.

If Yes in step 207, the amount of change in impedance between both palms (ΔZ / Δ
t) is calculated (step 208), and it is determined whether L _min ≦ | ΔZ / Δt | ≦ L _max (step 209). Where L _min
Is an effective lower limit of the preset impedance change amount, and _Lmax is the effective upper limit. The values of L _min and L _max may be fixed or may be changed.

If No in step 209, the input selection / setting process ends, and the process returns to the body specifying information input subroutine of FIG.

If Yes in step 209, | ΔZ /
The hierarchy is determined based on the magnitude of Δt |, and the amount of addition / subtraction from the initial setting value is determined (step 210). For example, L
_min ≦ | _ΔZ / _Δt | to moderate the ≦ L ₁ if 1, L _min
<| ΔZ / Δt | or minus a ≦ L ₂ if _2, L 2 <| Δ
If Z / Δt | ≦ _Lmax , 3 is added or subtracted. However, the setting method of the hierarchy is not limited to this.

After the addition / subtraction amount is determined in this manner, Δ
It is determined whether the polarity (sign) of Z / Δt is + or-(step 211). If the polarity is + (positive), the above-described addition / subtraction amount is added to the initial set value (or the previous set value) (step 212), and the process returns to the body specific information input subroutine of FIG. If the polarity is-(negative), the above-mentioned addition / subtraction amount is subtracted from the initial set value (or the previous set value) (step 213), and the process returns to the body specific information input subroutine of FIG.

A method in which the subject actually inputs the body specifying information using the apparatus 1 according to the above-described processing procedure will be described below.

When the measurement preparation processing (step 1) is completed, the apparatus enters the height setting mode, and the display section 3 displays the height setting mode and the initial height setting value (step 111).

When the target set value is smaller than the initial set value, both arms are extended straight to approximately the shoulder height in front of the body at a speed corresponding to the difference between the target set value and the initial set value (FIG. 7A). ,
From the state shown in FIG. 8B, the arm is bent as shown in FIGS. At this time, the impedance value between the palms decreases due to the contraction of the muscles of the arms on the conduction path of the applied current, and the display value of the height is gradually reduced from the initial setting value according to the amount of change (step 209). → 210 → 211
→ 213). When the target set value is larger than the initial set value, conversely, from the bent state of FIGS.
When the arms are extended as in (a) and (b), the impedance value between the palms increases due to the extension of the muscles of both arms, so that the displayed value of the height changes stepwise from the initial setting value according to the amount of change. (Step 209 → 210 →
211 → 212).

This operation is repeated until the display value of the height reaches the target set value, and when the height reaches the target set value, the control switch 12 on the right palm side is pressed to fix the set value (step 204), and thereafter the left palm side Is pressed to change the setting mode to the next weight setting mode (step 206).

Since the setting mode of each item of the body specifying information is set so as to shift in the order of height, weight, age, and gender, other items are similarly set in this order. When the setting of all items is completed, the READY flag is set (step 111), and the input of the body specifying information information is completed.

Here, the current application electrodes 7 and 8, the voltage measurement electrodes 4 and 5, and the measurement / calculation unit 20 constitute a characteristic index obtaining unit.

(Diet Simulation Game Processing) Hereinafter, the diet simulation game processing of step 14 in the flowchart of FIG. 4 will be described with reference to FIGS.
This will be described with reference to the flowchart of FIG. here,
FIG. 11 shows an example of a display screen of the display unit 3 at the time of playing the game.

First, it is determined whether or not to set a target value (step 301).

If Yes in step 301, target value input processing is performed (step 302). For example, a target body weight of 62.5 kg and a target body fat percentage of 20% are input.

If No in step 301, a standard value is calculated from the previously input body specifying information and the measurement result value, and this is set as a target value (step 303). For example,
If the person is 168 cm tall, weighs 74 kg, is 42 years old, is male, and has a body fat percentage of 25%, the target weight is 62.5.

A method in which the user actually performs a diet simulation game according to the above-described procedure will be described below.

First, two display areas of “set” and “not set” of the target value are displayed on the display unit 3.
By operating the left and right control switches 11 and 12 to move the cursor on the display screen to one of the display areas, it is selected whether or not to set a target value, and both control switches 11 and 12 are operated. This confirms the selection.

When the user sets his or her own target values of weight and body fat percentage, he or she inputs the target values; otherwise, the user inputs the target body weight information and body fat percentage which have already been inputted. A standard value is calculated from the measured value and set as a target value. The setting of the target value is performed in the same manner as the input of the body specific information. Therefore, the characteristic target acquisition unit is also similar to the characteristic index acquisition unit,
It is composed of current application electrodes 7 and 8, voltage measurement electrodes 4 and 5, and a measurement / calculation unit 20. When the target value is not set, the ROM 27, the RAM 28 and the CPU 2
9 constitutes a characteristic target acquisition means.

The surplus fat energy and the target value calculated from these numerical values are displayed on the display unit 3, and the surplus fat energy obstacle mark 33 and the subject mark 34 corresponding to the surplus fat energy are displayed on the display unit 3. Displayed on the screen. At this time, 10000 kcal is displayed as the initial value of the energy balance.

Next, the subject mark 34 is moved to select the eating menu and the exercise menu.

The subject mark 34 is moved in the X-axis direction on the display screen of the display unit 3 by the user operating the left and right control switches 11 and 12, and the subject mark 34 is changed by changing the impedance between both palms. Move in the axial direction.

First, the left control switch 11 is operated to move the subject mark 34 to the left in the X-axis direction on the display screen. When the subject mark 34 advances into the eating menu area 36 surrounded by a rectangular frame, the eating menu can be selected. For example, as shown in FIG. 11, 1: 500 kcal / time, 2: 1000 kcal /
Time, 3: One of three kinds of eating menus of 2000 kcal / time is selected. The subject mark 34 moves upward in the Y-axis direction when the impedance between the palms is changed in the increasing direction, and moves downward in the Y-axis direction when the impedance is changed in the decreasing direction. Then, both control switches 11 and 12 are operated to confirm the selection menu. When the menu is confirmed, the display of the selected eating menu is turned on. Here, the current application electrodes 7 and 8, the voltage measurement electrodes 4 and 5, the control switches 11 and 12, and the measurement / calculation unit 20 constitute a feeding content setting unit. Although the above-mentioned eating menu is constituted only when a certain amount of energy is ingested, there is a case where only exercise is performed without actually eating anything. Therefore, as a menu corresponding to such a case, the intake energy is 0 kcal. / Times may be provided.

The energy for the eating menu selected in this way is added, and the energy balance is displayed again.

Here, the energy balance is 10,000 kc
If it becomes more than al, surplus fat energy obstacle mark 3
3 increase by 1 and 10,000kca from energy balance
1 is subtracted and displayed. At this time, if the number of the surplus fat energy obstacle marks 33 is equal to or more than the specified displayable number, the game is over.

If the energy balance is less than 10,000 kcal, the subject control mark 12 is operated to move the subject mark 34 to the right in the X-axis direction on the display screen, and the exercise menu enclosed by a rectangular frame is operated. By proceeding to the area 37, the exercise menu can be selected. For example, as shown in FIG.
0 minutes), 2: Swimming (30 minutes), 3: Tennis (30 minutes),
4: Four kinds of exercise menus of soccer (30 minutes) are prepared, and the exercise intensity according to each exercise performed for a predetermined time can be selected. The method of selecting and confirming the menu is the same as in the case of the eating menu. When the menu is confirmed, the display of the selected exercise is turned on. Here, the current application electrodes 7 and 8, the voltage measurement electrodes 4 and 5, the control switches 11 and 12, and the measurement / calculation unit 20 constitute exercise content setting means.

The subject mark 34 is brought into contact with the surplus fat energy obstacle mark 33. At this time, as described above, the subject mark 34 indicates the impedance change ΔZ / Δt between the palms.
The moving direction is determined according to the polarity of .DELTA.Z, and the moving amount is determined according to the magnitude of .DELTA.Z / .DELTA.t. Here, the current application electrodes 7 and 8, the voltage measurement electrodes 4 and 5, the control switches 11 and 12, and the measurement / calculation unit 20 constitute an operation information input unit.

If the subject mark 34 is brought into contact with the surplus fat energy obstacle mark 33 more than a specified number of times within a specified time, the displayed surplus fat energy obstacle mark 33 is displayed.
The number of is reduced.

If the display of the surplus fat energy obstacle mark 33 has completely disappeared, the goal has been achieved and the game is over.

When the display of the surplus fat energy obstacle mark 33 remains, the energy corresponding to the basal metabolism and the prescribed energy corresponding to the selected exercise intensity are subtracted from the energy balance and displayed. The specified energy amount according to the exercise intensity is, for example, 100k for jogging.
cal / sec, 200 kcal / sec for swimming, 300 kcal / sec for tennis, and 500 kcal / sec for soccer.

In other words, in this game, if the user exercises properly while consuming proper energy through a proper meal, the goal of the diet can be achieved. If the value is 0 or less, or excessive energy is consumed while exercise is insufficient and surplus fat energy exceeds a prescribed amount, the game is over. That is, the progress of the game is controlled by evaluating the value of the energy balance, which is the simulation result in the diet simulation apparatus 1, by the CPU 20 as the evaluation means.

As described above, the user can simulate on the game how much energy should be taken and how much exercise should be performed in order to achieve the goal. Therefore, if the present diet simulation apparatus is used, the current state of the body composition is grasped by an index such as the body fat percentage calculated based on the measured value of the impedance between the palms, and the current state and the target are set by setting the target value. Can be grasped, and the necessity of diet can be more clearly recognized. In addition, by simulating the diet process through the game, it is possible to recognize the appropriate method for achieving the goal with a real feeling. In other words, the diet can be performed while always recognizing the difference between the target and the current state and an appropriate method for achieving the target, so that the diet can be continued in a fun and game-like manner.

In the present embodiment, an appropriate diet program may be displayed on the display unit 3 based on the current value and the target value such as weight and body fat percentage. Also, after the game, of the conditions set in the game, to display the amount of exercise required to consume the intake energy selected by the eating menu, or to achieve the goal with the exercise type selected in the exercise menu An appropriate diet program may be displayed by displaying necessary execution time and the like. In this way, an appropriate dieting method can be easily understood.
