The measured acetone concentration is stored in the nonvolatile memory 20 </ b> D together with the current date and time acquired from the timer 22.

  In step S104, based on the user's age input in step S100 and the acetone concentration measured in step S102, a recommended intake amount for the user's meal is acquired. The recommended intake amount includes at least one of a recommended intake weight, a recommended intake sugar mass, and a recommended intake energy amount. In this embodiment, a case where the recommended intake amount is the recommended intake sugar mass will be described.

  The acetone concentration of acetone, which is a byproduct of lipid metabolism, is thought to be equivalent to the amount of fat burned. When it runs short, the fat is burned and the acetone concentration becomes high. For this reason, normally, when there is a surplus of carbohydrate energy in the body after eating, the acetone concentration starts to decrease, and then the acetone concentration increases when there is insufficient carbohydrate energy in the body. That is, it can be said that the higher the acetone concentration, the higher the lipid metabolism. Therefore, the sugar mass that the user may ingest varies depending on the acetone concentration.

  For this reason, in step S104, the recommended intake sugar mass according to the age of the user and the measured acetone concentration is acquired from the recommended intake sugar mass table data 40 as shown in FIG. 5 as an example. Note that the recommended intake sugar mass table data 40 is stored in advance in the nonvolatile memory 20D, for example, but may be downloaded from the server by accessing the server via Wi-Fi (registered trademark) communication or the like.

  As shown in FIG. 5, the recommended intake sugar mass table data 40 is table data representing a correspondence relationship with age, acetone concentration, and recommended intake sugar mass. The age is divided into a plurality of categories (n), and the acetone concentration is divided into a plurality of levels (m levels) for each category. Thereby, the recommended intake sugar mass according to acetone concentration for every age can be acquired.

  The recommended intake sugar mass table data 40 shown in FIG. 5 is recommended intake sugar mass table data corresponding to age, but may be recommended intake sugar mass table data corresponding to the other user information described above. That is, the recommended intake sugar mass table data corresponding to user information including at least one of user age information, physique information, body composition information, and gender information may be used. In addition, when the input of user information is omitted, the recommended intake amount may be acquired based only on the acetone concentration measured in step S102. In this case, the recommended intake sugar mass corresponding to the measured acetone concentration may be obtained using table data representing the correspondence between the acetone concentration and the recommended intake sugar mass.

  In step S106, the recommended intake sugar mass acquired in step S104 is displayed on the display unit 14 as the target intake sugar mass. The target sugar intake mass may be transmitted to the load measuring device 30 via the communication unit 24 and displayed on the display unit 34 of the load measuring device 30.

  In step S108, the user is allowed to select a food to be consumed. Specifically, a selection screen for selecting a food to be consumed by the user from among a plurality of predetermined foods is displayed on the display unit 14 to allow the user to select. Examples of the predetermined foods include, but are not limited to, white rice, bread, pasta, udon and soba.

  In step S110, the target intake weight corresponding to the food selected in step S108 is calculated and displayed on the display unit 14. Specifically, the contained sugar mass corresponding to the food selected in step S108 is acquired from the contained sugar mass table data 50 as shown in FIG. 6 as an example. The contained sugar mass table data 50 is stored in advance in the nonvolatile memory 20D, but may be downloaded from the server by accessing the server through Wi-Fi (registered trademark) communication or the like.

  As shown in FIG. 6, the recommended ingested sugar mass table data 40 is table data representing a correspondence relationship between food and contained sugar mass per unit weight. In this embodiment, the unit weight is 100 g as an example, but is not limited thereto.

  Then, based on the acquired contained sugar mass and the recommended ingested sugar mass acquired in step S104, the target intake weight of the food selected in step S108 is calculated and displayed on the display unit 14. The target intake weight may be transmitted to the load measuring device 30 via the communication unit 24 and displayed on the display unit 34 of the load measuring device 30.

  Here, assuming that the contained sugar mass is A, the recommended sugar mass is B, and the target weight is C, where the unit weight of the food is 100 g, the target intake weight C is calculated by the following equation.

C = (B / A) × 100 (1)

  In addition, the user selects the type of meal such as the total value per day, per meal, and snacks, and the target intake weight is converted and displayed according to a predetermined conversion formula according to the selected meal type. You may do it.

  In step S112, the user is allowed to select a display unit for displaying the food measurement result. Specifically, a selection screen for selecting a display unit when displaying a measurement result of food taken by the user from among a plurality of predetermined display units is displayed on the display unit 14 and the user is allowed to select. . Examples of the predetermined display unit include, but are not limited to, weight [g], sugar mass “g”, energy [kcal], and the like.

  In step S114, the weight of the food is measured. Specifically, a message prompting to measure the weight of the food is displayed on the display unit 14. Note that the message may be displayed on the display unit 34 of the load measuring device 30. Here, the user places food on the measuring table 32 of the load measuring device 30 and measures the weight of the food. The measured weight of the food is transmitted from the load measuring device 30 to the ingested meal amount presenting device 10.

  In step S116, the measurement result of the food, that is, the weight of the food and the target intake weight calculated in step S110 are converted into a display unit selected in step S112 by a predetermined conversion formula, and the measurement value and the target value are respectively obtained. It is displayed on the display unit 14. These may be displayed on the display unit 34 of the load measuring device 30.

  When the display unit selected in step S112 is weight, no particular conversion is required, and the measured food weight and target intake weight are displayed as measured values and target values, respectively.

  Further, when the display unit selected in step S112 is sugar mass, the measured food weight and the target intake weight are each converted into sugar mass by a predetermined conversion formula for converting from weight to sugar mass. Are displayed on the display unit 14. Similarly, when the display unit selected in step S112 is energy, the measured food weight and the target intake weight are each converted into energy by a predetermined conversion formula for converting from weight to energy. It is displayed on the display unit 14.

  FIG. 7 shows a display example of measured values and target values. As shown in FIG. 7, the target value and the measured value are written together, and the food icon 60 selected in step S108 is displayed. In the example of FIG. 7, the icon 60 represents a case where “white rice” is selected as the food. In this way, the difference between the target value and the measured value of the weight of the selected food can be easily grasped.
