Abstract

The invention provides a poor physical condition determination device, method, and program enabling simple determination of a physical condition level.

A poor physical condition determination device 10 acquires a ketone concentration measurement measuring ketone excreted from a user, determines a physical condition level related to the physical condition of the user based on the acquired ketone concentration measurement, and outputs a determination result.

Claims

1. A poor physical condition determination device comprising:

a ketone concentration acquisition section that acquires a ketone concentration measurement measuring ketone excreted from a user;

a determination section that determines a physical condition level related to the physical condition of the user based on the ketone concentration measurement acquired by the ketone concentration acquisition section; and

an output section that outputs a determination result by the determination section.

2. The poor physical condition determination device of claim 1, wherein:

the determination section determines a poor physical condition level related to poor physical condition of the user as the physical condition level based on a comparison result between the ketone concentration measurement and at least one predetermined threshold value, or based on a plurality of ketone concentration measurements measured in the past and including the ketone concentration measurement.

3. The poor physical condition determination device of claim 2, wherein:

the threshold value is provided for each user attribute including at least one of gender, age, build, or body composition; and

the determination section determines the poor physical condition level according to the user attribute.

4. The poor physical condition determination device of claim 1, wherein:

the determination section determines a diet level related to dieting by the user as the physical condition level based on a comparison result between the ketone concentration measurement and at least one predetermined threshold value, or based on a plurality of ketone concentration measurements measured in the past and including the ketone concentration measurement.

5. The poor physical condition determination device of claim 4, wherein:

the determination section determines the diet level based on a comparison result between the ketone concentration measurement and at least one predetermined threshold value, or based on a difference or ratio between the ketone concentration measurement measured a previous time and the ketone concentration measurement measured this time.

6. The poor physical condition determination device of claim 5, wherein:

the determination section determines the diet level based on a difference or ratio between the ketone concentration measurement measured a previous time and the ketone concentration measurement measured this time, and elapsed time from the previous measurement to the current measurement.

7. The poor physical condition determination device of claim 4, wherein:

the determination section determines the diet level based on a comparison result between the ketone concentration measurement measured before a meal and the ketone concentration measurement measured after a meal.

8. The poor physical condition determination device of claim 4, wherein:

the determination section determines whether or not a rebound has occurred as the diet level based on a comparison result between a variation curve expressing variation in the plurality of ketone concentration measurements, and a predetermined rebound curve expressing variation in the ketone concentration measurements when a rebound from a diet has occurred.

9. The poor physical condition determination device of claim 4, wherein:

the determination section determines the diet level based on a comparison result between an equation expressing the plurality of ketone concentration measurements measured for the user, and an equation expressing ketone concentration measurements of ketone concentration measured for subjects performing normal dieting.

10. The poor physical condition determination device of claim 1, further comprising a measurement section that measures ketone excreted from the user.

11. The poor physical condition determination device of claim 1, wherein the ketone excreted from the user are acetone contained in breath exhaled from the user.

12. A poor physical condition determination method comprising:

acquiring a ketone concentration measurement measuring ketone excreted from a user;

determining a physical condition level related to a physical condition of the user based on the acquired ketone concentration measurement; and

outputting a determination result.

13. A non-transitory recording medium stored with a poor physical condition determination program that causes processing to be executed on a computer, the processing comprising:

acquiring a ketone concentration measurement measuring ketone excreted from a user;

determining a physical condition level related to a physical condition of the user based on the acquired ketone concentration measurement; and

outputting a determination result.
