Abstract

A device includes a body weight obtainment unit for obtaining measurement data; a storage unit for storing the measurement data; a target calculation unit that, based on the measurement data in, calculates a target diurnal fluctuation amount including a body weight fluctuation amount during sleep and a body weight diurnal target increase/decrease amount; and a computation unit that, based on the target diurnal fluctuation amount, calculates a target value to serve as a target when measuring a pre-sleep body weight value at a second timing before the measurement subject sleeps relative to a post-waking body weight value that is measured at a first timing after the measurement subject wakes. The target calculation unit calculates the diurnal target increase/decrease amount based on the measurement data in the storage unit so that the diurnal target increase/decrease amount is within a predetermined increase/decrease percentage range of the post-waking body weight value.

a computation unit that, based on the target diurnal fluctuation amount obtained by said target obtainment unit, calculates a target value to serve as a target to be achieved when measuring a pre-sleep body weight value at a second timing near when the measurement subject sleeps, based on a post-waking body weight value measured at a first timing after the measurement subject wakes,

wherein said target obtainment unit calculates said diurnal target increase/decrease amount based on said measurement data in said storage unit so that said diurnal target increase/decrease amount is within a predetermined increase/decrease percentage range of said post-waking body weight value.

2. The body weight management device according to claim 1,

wherein said target obtainment unit compares a predetermined increase/decrease percentage in said predetermined increase/decrease percentage range from an initial body weight value at an initial day/time to a target body weight value set as a target to be achieved when body weight management is completed at a target date/time that serves as a day/time for completing the body weight management with a body weight increase/decrease percentage from a first day/time at which said measurement data was stored in said storage unit to a second day/time that is after said first day/time, and calculates said diurnal target increase/decrease amount based on a result of the comparison.

3. The body weight management device according to claim 1, wherein said target obtainment unit comprises:

a body weight calculation unit that calculates a predetermined body weight value at a predetermined day/time in a case where the body weight value changes in accordance with the predetermined increase/decrease percentage in said predetermined increase/decrease percentage range, from an initial body weight value at an initial day/time to a target body weight value at a target date/time; and

an increase/decrease amount calculation unit that compares said post-waking body weight value measured at a predetermined day/time with said predetermined body weight value calculated by said body weight calculation unit, and calculates said diurnal target increase/decrease amount based on a result of a comparison of the values.

4. The body weight management device according to claim 3,

wherein when the result of the comparison of said values indicates that said post-waking body weight value measured at said predetermined day/time is greater than said predetermined body weight value, said increase/decrease amount calculation unit calculates, as said diurnal target increase/decrease amount, the lesser of an increase/decrease amount corresponding to a predetermined percentage of said post-waking body weight value measured at said predetermined day/time and an increase/decrease amount according to said predetermined increase/decrease percentage;

and

said predetermined percentage is a maximum increase/decrease percentage in said predetermined increase/decrease percentage range.

5. The body weight management device according to claim 3,

wherein when the result of the comparison of said values indicates that said post-waking body weight value measured at said predetermined day/time is less than said predetermined body weight value, said increase/decrease amount calculation unit calculates, as said diurnal target increase/decrease amount, the increase/decrease amount according to said predetermined increase/decrease percentage.

6. The body weight management device according to claim 3,

wherein when the result of the comparison of said values indicates that said post-waking body weight value measured at said predetermined day/time is equal to said predetermined body weight value, said increase/decrease amount calculation unit calculates said diurnal target increase/decrease amount by dividing a difference between said post-waking body weight value measured at said predetermined day/time and said target body weight value by a number of days from said predetermined day/time to said target date/time.

7. The body weight management device according to claim 1,
