  In recent years, measurement of basal metabolic rate for prevention of adult diseases and the like has been attracting attention. However, in order to determine an accurate basal metabolic rate of the measurement subject, an expensive and large-scale apparatus is usually required. For example, a method of measuring a carbon dioxide gas and a nitrogen gas of breathing for 10 minutes by supine after 14 hours on an empty stomach has been used as a medical method. However, when such a method is used, it is necessary to satisfy various measurement conditions, and the person to be measured must wear a mask or a mouthpiece and remain at rest for a long time.

The effect that the amount of metabolism can be measured is obtained.

First, in order to help understanding of the present invention, its background and outline will be described.
In the present invention, the weight of the subject at rest is measured at two different times before and after the rest, and the basal metabolic rate of the subject is measured based on the weight loss during the rest period.

In general, changes in the weight of a human body are based on factors as shown in FIG.
Here, in the present invention, basal metabolism is measured on the basis of body weight changes at rest without ingesting food and drink and not performing daily activities, so food and water intake and life activity metabolism are not considered. To do. Then, it turns out that the weight loss amount at rest is calculated by the following formula.

Weight loss at rest = Weight loss due to basal metabolism-Metabolite water amount + Insensitive transpiration amount + Meal-induced body heat production amount + urination defecation amount In other words, the weight loss amount due to basal metabolism is calculated by the following formula You can see that

Weight loss due to basal metabolism = Weight loss at rest + Metabolite water volume-Insensitive transpiration-Meal-induced body heat production-Defecation volume Measure the weight loss at rest and measure the weight loss By subtracting the effects of the amount of metabolized water, the amount of insensitive steaming, the amount of diet-induced body heat production, and the amount of urination and defecation during the period, the weight loss due to basal metabolism can be obtained. If the weight loss due to basal metabolism is known, the basal metabolism can be calculated.

[Embodiment]
Next, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 2 is a system diagram showing a configuration of a basal metabolic rate measuring system according to one embodiment of the present invention.

  This embodiment demonstrates the case where the bedtime at night is used as a rest. However, it is possible to measure the basal metabolic rate other than at bedtime when the person is at rest without taking in food or drink and performing daily activities.

  As shown in FIG. 2, the basal metabolic rate measurement system according to the present embodiment includes a basal metabolic rate measurement device 10 and a scale 20 for measuring the weight of the subject.

  The weight scale 20 includes a measurement unit 21 for measuring the body weight and a display unit 22 for displaying the weight measured by the measurement unit 21. Then, the weight information measured by the measuring unit 21 of the weight scale 20 is transmitted to the basal metabolic rate measuring device 10.

  The basal metabolic rate measuring device 10 is provided with an input unit 11 for inputting information on life activity before and after the weight measurement and a display unit 12 for displaying the measured basal metabolic rate.

The appearance of the basal metabolic rate measuring device 10 is shown in FIG.
In the basal metabolic rate measuring apparatus 10, “before going to bed”, “3 hours before meal”, “3 hours after meal”, “after waking up”, “after urination”, “after defecation” are displayed as the input unit 11. Button is provided.

The “before going to bed” and “after getting up” buttons are buttons for distinguishing whether the measured weight is before going to bed or after getting up.
The buttons “3 hours before meal” and “3 hours after meal” are buttons for inputting whether or not 3 hours have elapsed since the end of the meal when the weight before bedtime is measured. It is.

  That is, when measuring the weight before going to bed, the measurement subject operates the “before going to bed” button and the “3 hours before meal” or “after 3 hours after meal” button.

  The “after urination” and “after stool” buttons are buttons for inputting whether or not urination or defecation was performed during the period from getting up to measuring the body weight when measuring the weight when getting up. .

Next, a specific configuration of the basal metabolic rate measuring apparatus 10 of the present embodiment is shown in FIG.
As shown in FIG. 4, the basal metabolic rate measuring apparatus 10 of the present embodiment includes an input unit 11, a display unit 12, a storage unit 13, a weight information receiving unit 14, and a CPU (Central Processing Unit) 15. The timer 16 and the network interface 17 are connected via a bus 18.

The weight information receiving unit 14 receives the weight information transmitted from the weight scale 20 and stores it in the storage unit 13.
The timer 16 is controlled to be set and reset by the CPU 15 and measures an elapsed time from the set time.

The network interface 17 is connected to a personal computer or the like via a LAN (Local Area Network) or the like, for example.
The display unit 12 includes a liquid crystal monitor, for example, and displays the measured basal metabolic rate, warning information, input guidance, and the like.

  In addition to the buttons shown in FIG. 3, the input unit 11 is provided with an operation unit that can input the name, age, sex, etc. of the person to be measured. Various types of information input from the input unit 11 are stored in the storage unit 13.

  The CPU 16 measures the basal metabolic rate by controlling the input unit 11, the display unit 12, the storage unit 13, the weight information receiving unit 14, the timer 16, the network interface 17 and the like based on a predetermined program.

  FIG. 5 shows an example of a functional configuration of the basal metabolic rate measuring apparatus 10 realized by performing processing based on a predetermined program in this way.

  Referring to FIG. 5, the basal metabolism measuring device 10 of the present embodiment includes an input unit 11, a display unit 12, a weight information receiving unit 14, a calculation unit 31, a correction unit 32, and a basal metabolism calculation. Part 33.

  Based on the weight information received by the weight information receiving unit 14, the calculation unit 31 calculates the nighttime weight loss based on the two weight values measured before and after waking up measured by the weight scale 20.

  The correction unit 32 corrects the nighttime weight loss calculated by the calculation unit 31 based on the biological activity information input by the input unit 11 such as the elapsed time after meals, the defecation at rest, and the presence or absence of urination. .

  The basal metabolic rate calculating unit 33 calculates the basal metabolic rate based on the nighttime weight loss after being corrected by the correcting unit 32 and displays the basal metabolic rate on the display unit 12. When a device such as a personal computer is connected, the basal metabolism measuring device 10 transmits the weight information and the calculated basal metabolism through the network interface 17 shown in FIG.

  The correcting unit 32 and the basal metabolic rate calculating unit 33 can know the time interval at which the two weight values for which the weight loss amount has been calculated are measured based on the timer value of the timer 16.

Next, a specific method for how the correction unit 32 corrects the nighttime weight loss will be described.
First, based on the time measured by the timer 16 and data as shown in FIG. 6, the correction unit 32 calculates the amount of metabolic water and the amount of insensitive digestion by the following method. FIG. 6 is a table showing the standard values of the amount of metabolized water and the amount of dead-sensitive excretion for each 24 hours.

[Metabolic water]
Referring to FIG. 6, the average amount of metabolic water in a 24-hour person having a weight of 60 kg is 300 g. That is, it can be considered that the amount of metabolic water in 24 hours per 1 kg of body weight is 5 g (300 g / 60 kg). And it seems that the amount of metabolic water also increases in proportion to body weight. Therefore, it is possible to calculate the amount of metabolic water in a certain sleeping time of a person with a certain weight value by the following formula using the average value in the case of the weight of 60 kg.
Metabolic water amount = body weight value × 5 g × sleeping time / 24 hours For example, the metabolic water amount when the body weight is 65 kg and the sleeping time is 8 hours is calculated by the following equation.
Metabolic water amount = 65 × 5 × 8 / 24≈108.3 [g]

[Insensitive excretion]
Next, it seems that the amount of decrease due to insensitive digestion, a phenomenon in which moisture evaporates unconsciously by the skin and breathing, also increases in proportion to body weight. Then, referring to FIG. 6, the average insensitive excretion amount in 24 hours for a person weighing 60 kg is 900 g. That is, it can be considered that the insensitive excretion amount for 24 hours per kg of body weight is 15 g (900 g / 60 kg). Therefore, using the average value in the case of 60 kg of body weight, it is possible to calculate the insensitive excretion amount in a certain sleep time of a person with a certain weight value by the following formula.
Insensitive digestion amount = body weight value × 15 g × sleeping time / 24 hours For example, the amount of metabolic water when the body weight is 65 kg and the sleeping time is 8 hours is calculated by the following equation.
Insensitive excretion = 65 × 15 × 8/24 ≒ 324.9 [g]

  Next, based on the time measured by the timer 16 and the information on the life activity input by the input unit 11, the correction unit 32 calculates the amount of meal-induced body heat production and the amount of urination and defecation by the following method. To do.

[Diet-induced body heat production]
Meal-induced body heat production is energy consumption associated with meals such as chewing, digestion, absorption, and metabolism. Therefore, it is not necessary to consider when a certain period of time has elapsed after a meal. In the present embodiment, correction is performed only when 3 hours have not passed since meals when measuring weight before going to bed.

  Generally, the energy accompanying digestion / absorption is considered to be about 200 kcal / day. This 200 kcal corresponds to a weight of about 30 g. Assuming that there are three meals per day, the amount of meal-induced body heat production by one meal is considered to be about 10 g. Therefore, when the “3 hours before meal” button shown in FIG. 3 is operated at the time of weight measurement before going to bed, the correction unit 32 reduces the nighttime weight loss by setting the diet-induced body heat production to 10 g. Correct the amount. When the “3 hours after meal” button shown in FIG. 3 is operated during the weight measurement before going to bed, the correction unit 32 sets the meal-induced body heat production to 0 g and reduces weight at night. Correct the amount.

[Urine defecation volume]
Next, the correction unit 32 determines the value of the urination and defecation amount. Here, the standard value of the amount of urination once is about 200 g, and the standard value of the amount of defecation (including the amount of urination) is about 390 g.

  Therefore, when the “after urination” button shown in FIG. 3 is operated at the time of weight measurement after getting up, the correction unit 32 corrects the nighttime weight loss by setting the urination defecation amount to 200 g. When the “after defecation” button shown in FIG. 3 is operated during weight measurement after waking up, the correction unit 32 corrects the nighttime weight loss by setting the defecation amount to 390 g. When the weight after waking up is measured, if neither the “after urination” button nor the “after defecation” button shown in FIG. 3 is operated, the correction unit 32 sets the urination defecation amount to 0 g. As mentioned above, the weight loss at night is corrected.

  Here, standard values set in advance as the urination amount and the defecation amount are used, but these values may be changed for each individual. For example, the standard value as described above is obtained by measuring and averaging the amount of urination (defecation amount) for each individual according to the difference between the weight before urination (before defecation) and the weight after urination (after defecation). Replace it. By doing so, the basal metabolic rate measured can be made more accurate.

[Calculation of basal metabolic rate]
And the correction | amendment part 32 is calculated by the calculation part 31 by the following formula | equation mentioned above using the amount of metabolic water obtained by the method as mentioned above, a dead-sensitive excretion amount, a meal induction body heat production amount, and a urination defecation amount The amount of weight loss due to basal metabolism is calculated by correcting the amount of nighttime weight loss.

Weight loss due to basal metabolism = weight loss at rest + metabolite water amount−insensitive steaming amount−meal-induced body heat production amount−defecation amount of urination and basal metabolism amount calculating unit 33 is corrected by correcting unit 32 Basal metabolism is calculated based on weight loss due to subsequent basal metabolism. For example, the basal metabolism calculating unit 33 calculates the basal metabolism based on a table as shown in FIG.

  FIG. 7 is a graph showing the relationship between the basal metabolic rate and the weight loss. Since the basal metabolic rate is calories burned at 24 hours, the weight loss shown in FIG. 6 indicates the weight loss due to basal metabolism at 24 hours.

Here, since the amount of weight loss of a person with a basal metabolism of 1500 kcal is 210 g, for example, the basal metabolism calculation unit 32 calculates the basal metabolism by the following formula using this value.
Basal metabolic rate = weight loss due to basal metabolism × 24 / sleep time / 210 g × 1500 kcal

Next, the operation of the basal metabolic rate measurement system of this embodiment will be described with reference to the flowchart of FIG.
Here, the description will be made assuming that the sleeping time is 8 hours, the weight before going to bed is 64.5 kg, and the weight after waking up is 64.2 kg. In addition, it is assumed that 3 hours have not passed from dinner to the measurement of body weight before going to bed, and that the body weight was measured after waking up without urination or defecation.

  First, the person to be measured measures the weight with the weight scale 20. Then, the weight scale 20 transmits the measured weight information to the basal metabolism measuring device 10, and the basal metabolism measuring device 10 receives this weight information (S101).

  Then, the basal metabolic rate measuring apparatus 10 instructs the subject to input various biological information by performing input guidance using the display unit 12. Here, since the body weight is measured before going to bed, the person to be measured operates the “before going to bed” button shown in FIG. In this case, since 3 hours have not passed since the meal, the person to be measured operates the button “3 hours before the meal”.

  Then, in the basal metabolism measuring device 10, since it is determined that the received weight information is before going to bed (S102), the timer 16 is set (S103), and the measured weight value is stored (S104). .

After this, it is assumed that the person to be measured goes to bed and wakes up after 8 hours and then measures the weight with the weight scale 20 again. Then, this weight information is received by the basal metabolism measuring device 10 (step 101). The basal metabolic rate measuring apparatus 10 that has received the weight information instructs the subject to input various biological information by performing input guidance on the display unit 12 in the same manner as before going to bed. Here, since the weight measurement is performed after waking up, the measurement subject operates the “after waking up” button shown in FIG. 3. Since the urination and defecation are not performed here, the person to be measured does not operate either the “after urination” button or the “after defecation” button.
Then, since the basal metabolism measuring device 10 determines that the received weight information is after waking up (S102), the timer value of the timer 16 is acquired (S105).

  Then, the calculation unit 31 in FIG. 5 calculates the difference between the stored weight value before bedtime and the weight value after waking up as the weight loss at night (S106). Here, since the weight before going to bed is 64.5 kg and the weight after getting up is 64.2 kg, the weight loss at night is 300 g.

  Next, the correction unit 32 corrects the nighttime weight loss calculated by the calculation unit 31 (S107).

Here, the correction unit 32 uses the body weight after getting up to calculate the amount of metabolized water and the amount of insensitive digestion as follows: amount of metabolized water = 64.2 × 5 × 8/24 = 107 g
Insensitive excretion = 64.2 x 15 x 8/24 = 321 g
Diet-induced body heat production = 10 g
Defecation volume = 0g

And the correction | amendment part 32 correct | amends the nighttime weight loss amount 300g as follows.
Weight loss due to basal metabolism = 300 g + 107 g-321 g-10 g
= 76g

  Then, the basal metabolism calculation unit 33 calculates the basal metabolism using the nighttime weight loss (corrected by the basal metabolism) after being corrected by the correction unit 32 (S108).

Here, since the corrected weight loss at night is 76 g, the basal metabolic rate is calculated by the following equation.
Basal metabolic rate = 76 g x 24/8 x 210 g x 1500 kcal
= 1628.36 kcal

  Then, the basal metabolism calculated by the basal metabolism calculation unit 33 is displayed on the display unit 12 (S109), and is transmitted to the personal computer or the like via the network interface 17 shown in FIG. 4 together with the weight value (S110). ). Then, the timer 16 is reset (S111), and the process ends.

  According to the basal metabolism measuring system of the present embodiment, the measurement subject measures the weight with the weight scale 20 before going to bed, inputs information to the basal metabolism measuring apparatus 10, and after waking up, the weight is again measured with the weight scale 20. It is possible to obtain an accurate basal metabolic rate only by a simple operation of measuring the above and inputting information to the basal metabolic rate measuring apparatus 10.

  In particular, since a weight scale is already provided in general homes, it is possible to accurately measure the basal metabolism only by preparing only a basal metabolism measuring device that can be connected to the weight scale. In addition, if the weight value measured with the weight scale is input by an input means such as a numeric keypad without connecting the weight scale and the basal metabolism measuring device, the weight scale and the basal metabolism measuring device are connected. It is possible to measure basal metabolism without doing it.

  Thus, according to the basal metabolism measuring system of the present embodiment, the basal metabolism can be accurately measured at home without requiring a complicated device.

Further, in the present embodiment, the case where the weight scale 20 and the basal metabolic rate measuring device 10 are configured by different devices has been described, but the present invention is not limited to such a form. Even when the weight scale 20 and the basal metabolism measuring device 10 are integrated into one device, the same can be applied.
In addition, if the difference between the weight before going to bed and the weight after getting up is too large, the person to be measured before going to bed and the person to be measured after getting up are considered to be different people. You may make it display a warning.

  In the basal metabolism measurement system of this embodiment, an accurate basal metabolism cannot be calculated when a meal or water is ingested during sleep. However, if you get up in the middle of the night and ingest water, measure your body weight before going to bed again, and measure your basal metabolic rate if you have enough time to get up. Can do.

  In addition, since the basal metabolic rate value may include errors if measured only once, measure the basal metabolic rate for several consecutive days and calculate the average of the values for several days using the moving average method, etc. If displayed in such a manner, a more accurate result can be obtained.

[Modification]
In the above embodiment, the weight loss during sleep is corrected by the amount of metabolic water, the amount of insensitive steaming, the amount of diet-induced body heat production, and the amount of urination and defecation, so that the weight loss due to basal metabolism is obtained. If the subject is required not to eat for a certain period of time before going to bed, and not to urinate or defecate before waking up, the amount of food-induced body heat production and urinary defecation can be reduced. No need to consider. That is, it is possible to obtain a weight loss due to basal metabolism only by correcting the weight loss during sleep only by the amount of metabolic water and the amount of insensitive steaming.

  In the above embodiment, the weight loss amount at night is calculated from the weight values before going to bed and after waking up, but the weight loss amount during the period when the body is rested by at least two weight values measured at different times. If it is possible to calculate basal metabolism, it is possible to measure the basal metabolic rate in the same manner.
