Description

Technical field of the invention.

The subject of the invention is a device for evaluating and controlling the daily amount of carbohydrates and proteins to be consumed for an individual's target weight.

It concerns the technical field of materials used in dietetics to help regulate the diet of an individual.

State of the art.

Various methods exist to assess and control the daily amount of kilocalories. The Weight Watchers® method, for example, requires the individual to weigh each food and translate this weight into points which probably correspond, at least in part, to kilocalories, which must then be added up per meal and per day.

We know from patent document CN204292757 (LUO SIDUN), a compartmentalized container making it possible to determine the number of calories absorbed by an individual. This container includes a compartment for vegetables, a compartment for meat or fish and a compartment for "stable" food. The inner wall of each compartment is graduated in calories. An individual can easily determine the number of calories taken in each meal. In a preferred embodiment, the compartments are in the form of bowls which fit into each other. Concentric graduated circles each define a predefined volume corresponding to a number of calories. This device gives no indication of the number of calories that an individual should ideally consume daily for a desired weight goal.

The website www.thedietplate.com presents a plate with five compartments: protein, carbohydrates, vegetables, sauce and cheese. A curved curve and a square line, both graduated, delimit these different compartments. The surface of the different compartments varies according to sex and / or age. Three models of plates are required to meet the needs of men, women and children.

The invention aims to remedy the shortcomings of the devices known from the prior art. In particular, an objective of the invention is to provide a universal device for precise evaluation and control of the daily amount of carbohydrates and proteins (i.e. calories) to consume for an individual's weight objective.

Another objective of the invention is to provide a device which is simple to use and inexpensive to manufacture.

Yet another objective of the invention is to be able to determine precisely and optimally the daily amount of carbohydrates and proteins to consume for an individual's weight objective.

Disclosure of the invention.

-3The solution proposed by the invention is a device for evaluating and controlling the quantity of carbohydrates and proteins to be consumed per meal for an individual's weight objective, comprising:

- a plate whose bottom shows:

• a series of homothetic and concentric geometric shapes graduating the background and each defining a predefined surface, • segments dividing the geometric shapes into two series of sectors:

o a series of sectors for proteins, o a series of sectors for carbohydrates, o each sector defining a predetermined quantity of carbohydrates and proteins to be consumed per meal,

- an IT management unit adapted to implement a logical IT process which determines an output data as a function of input data, • the input data are: the sex of the individual, the weight of the individual , the size of the individual, the age of the individual, a datum characteristic of the physical activity of the individual, • the output datum is the geometric form to be taken into account when placing proteins and carbohydrates.

The specific graduation of the bottom of the plate makes it possible to use one and the same plate regardless of the age and sex of the individual. The plate can thus be considered as universal, that is to say suitable for any individual. In addition, the individual can know simply, quickly and precisely, which geometric figure he must use to reach his weight goal.

Other advantageous features of the invention are listed below. Each of these characteristics can be considered alone or in combination

-4combination with the remarkable characteristics defined above, and be the subject, if necessary, of one or more divisional patent applications:

The angle formed by the segments is preferably chosen so that, for a given geometric figure of coast, the sector of the first series dedicated to proteins has an area between half and third of that of the sector of the second series dedicated to carbohydrates.

- Advantageously, the logical computer process determines the geometric form to be taken into account for placing proteins and carbohydrates by applying at least one of the following formulas:

KCAL Male ~ (88.36 + 13.4xKG + 4.8xCM-5.7xANS) x ACT

KCALpemme = (447.6 + 9.2xKG + 3.1xCM-4.3xANS) x ACT

Or :

KCAL corresponds to the number of daily kilocalories necessary for an individual,

KG corresponds to the target weight of the individual in Kilogram defined according to a normal BMI (Body Mass Index) of the individual,

CM corresponds to the size of the individual in centimeters,

ANS corresponds to the age of the individual in years,

ACT is a coefficient taking into account physical activity

- Advantageously, the IT management unit implements the logical IT process by subtracting at least a predefined percentage of kilocalories from the number of kilocalories calculated according to the above formula.

- The geometric figures are preferably concentric circles advantageously having radii between 6 cm and 12 cm.

- The salient angle formed by the segments is advantageously 130 ° when the geometric figures are concentric circles.

- Geometric figures can be squares, ellipses, polygons, etc.

- According to one embodiment, the geometric figures are molded in relief and protrude from the upper surface of the bottom.

Description of the figures.

Other advantages and characteristics of the invention will appear better on reading the description of a preferred embodiment which will follow, with reference to the appended drawings, produced by way of indicative and nonlimiting examples and in which:

- Figure 1 is a top view of a plate according to the invention,

- Figure 2 is a sectional view along A-A of the plate of Figure 1,

FIG. 3 illustrates in a simplified manner the IT structure of a computer terminal used in the invention,

FIG. 4 is a top view of a plate according to the invention, according to an alternative embodiment,

- Figure 5 is a top view of a plate according to the invention, according to another alternative embodiment.

Preferred embodiments of the invention.

The invention is capable of implementing a coherent sequence of steps making it possible to achieve a desired result. These steps generate manipulations of physical elements, in particular signals (electrical or magnetic) capable of being stored, transferred, combined, compared, etc.

The invention is implemented by means of a computer application executed by a computer terminal. For the sake of clarity, it should be understood in the sense of the invention that "the computer terminal does something" means "the computer application executed by a processor of the computer terminal does something". Just as "the computer application does something" means "the computer application executed by the processor of the computer terminal does something".

Still for the sake of clarity, the present invention may refer to one or more “logical computer processes”. These correspond to the actions or results obtained by executing the instructions of different computer applications. Also, it should also be understood within the meaning of the invention that "a logical computer process is suitable for doing something" means "the instructions of a computer application executed by a processor do something".

Referring to Figures 1 and 2, the device according to the invention comprises a plate 1, preferably a flat plate. The latter has conventionally a bottom 10 and a peripheral rim 11 which is raised relative to said bottom. The bottom 10 is preferably in the form of a disc for the sake of simplification of the design of the plate 1, although it may be of any other shape (square, rectangular, oval, etc.). The plate 1 is advantageously made of a rigid material making it reusable, for example ceramic, plastic, or glass. It could however be for single use and in this case be made of another material, preferably a recyclable material such as cardboard.

In Figure 1, the bottom 10 of the plate 1 is graduated by concentric circles C1-C6. These circles are arranged on the upper face of the bottom 10, that is to say the face which is visible to an individual when the plate 1 is placed on a support such as a table. The circles C1-C6 have their common center O which is preferably centered in the middle of the bottom 10. They can be painted or colored in the mass, each circle having a different color to facilitate its location. They can also have the same color and be each identified by its own inscription, for example by letters and / or numbers. The circles C1-C6 can also be molded in relief and, as illustrated in FIG. 2, protrude from 1 mm to 5 mm from the upper surface of the bottom 10.

-7Each circle defines a predefined surface disk. Table 1 below illustrates a preferred example of retained surface and corresponding radius for each circle, allowing in particular to obtain a universal graduation, usable as well by men as by women, adults or children.

Circle Area (cm ² ) Radius (cm) This 120 6.2 c ₂ 180 7.6 c ₃ 240 8.7 c ₄ 300 9.8 c ₅ 360 10.7 c ₆ 420 11.6

Table 1

A higher or lower number of circles can obviously be provided. Similarly, other rays can be envisaged.

In FIG. 1, radial segments Ri, Fb have for common origin the common center O of the circles C1-C6, and divide the latter into two series of disk sectors. As an illustrative example, the salient angle formed by the radial segments Ri, Fb is 130 °, so that the disk sectors of the first series have an angle of 130 ° and the disk sectors of the second series have an angle of 230 °. At equivalent radius, the disk sectors of the first series therefore have a smaller surface than the disk sectors of the second series. The first series of sectors is dedicated to proteins and the second series of sectors is dedicated to carbohydrates.

Each disc sector defines a predetermined amount of carbohydrates and proteins that must be consumed to reach a target weight. The

The method for selecting the circle to be taken into account for placing the proteins and the carbohydrates will now be described in detail.

BMI (Body Mass Index) is a ratio between an individual's weight and height, according to the following formula: BMI = Weight (in kg) / Height ² (in meters).

In adults (over 18), the BMI is constant and does not vary with age. A normal BMI is around 20 kg / m ² for a woman, 24 kg / m ² for a man. The difference is explained by the difference in muscle mass between the two sexes.

BMI is not constant in children (up to 18 years of age). Baseline values vary by age and gender. These are generally plotted on a percentile curve known as the “bodybuilding curve” of the National Nutrition Health Program, which makes it possible to assess the nutritional status according to the age and sex of the child. These curves of build are present on the children's health book and / or accessible on the website of the national institute of prevention and education for health (http://inpes.santepubliquefrance.fr/CFESBases/catalogue/ pdf / BMI / curves_enfan ts.pdf).

BMI allows you to estimate the ideal weight of an individual based on their size, age and gender. Table 2 below illustrates examples of weight targets for different individuals:

Individual Size (m) Adequate BMI (kg / m ² ) Weight target (Kg) Adult man 1.97 24 93 Adult woman 1.60 20 51 10 year old boy 1.45 16.5 35 10 year old girl 1.40 16 31

Table 2

-9Empirical formulas make it possible to determine the number of kilocalories (KCAL) daily necessary for an individual, according to his age, his size and his physical activity. These empirical formulas read as follows:

KCALMan = (88.36 + 13.4xKG + 4.8xCM-5.7xANS) x ACT

KCALpemme = (447.6 + 9.2xKG + 3.1xCM-4.3xANS) x ACT

Where: KG = target weight of the individual in Kilogram

CM = height of the individual in centimeters

ANS = age of the individual in years

ACT = coefficient taking into account physical activity with, preferably:

ACT = 1 for physical activity of less than 2 hrs / week ACT = 1.05 for physical activity of more than 2 hrs / week ACT = 1.10 for physical activity of more than 6 hrs / week

Table 3 below shows the number of daily kilocalories (KCAL) necessary for the individuals defined in Table 2 and calculated according to the formulas above:

Individual Weight target (Kg) Cut (Cm) Age Physical activity (h / week) KCAL Adult man 93 197 21 7 2377 Adult woman 43 146 72 1 986 10 year old boy 35 145 10 1 1196 10 year old girl 31 140 10 1 1124

Table 3

-10The graduated plate in accordance with the invention supports lunch (noon) and dinner (evening) which represent around 55% of the calories consumed daily. The logical computer process described further in the description subtracts 40% for breakfast, snacks, fats, sugary and / or alcoholic beverages and fruits (this percentage may vary depending on the individual and his eating behavior, and for example be between 20% and 50%). The logical IT process also subtracts 5% for vegetables which can be eaten at will (± 400 g).

21-year-old adult men should consume 2377 KCAL which can be broken down as follows:

- 40% for breakfast, snacks, fats, sugary and / or alcoholic drinks and fruits, that is 951 KCAL;

- 5% for vegetables, i.e. 119 KCAL.

This leaves 1,307 KCAL for two meals (midday and evening), or 654 KCAL per meal.

The inventor has found that 300 KCAL of carbohydrates and proteins occupy an area of approximately 200 cm ² .

654 KCAL then occupy an area of approximately 420 cm ² ; or a circle of about 11.7 cm in radius. This adult man must therefore place his proteins and carbohydrates in circle C6. To obtain a number of KCALs equally distributed between proteins and carbohydrates, proteins (ex: lean beef, chicken, lean fish, ...) are placed in the sector of the first series and carbohydrates (rice, pasta,. ..) are arranged in the sector of the second series.

72-year-old adult women must absorb 986 KCAL daily

27.5% at noon and 27.5% in the evening, or 271 KCAL per meal, which represents an area of approximately 180 cm ² ; or a circle of approximately 7.6 cm in radius. This adult woman can therefore place her proteins and carbohydrates in circle C2, the proteins being arranged in the sector of the first series and the carbohydrates being arranged in the sector of the second series.

The 10-year-old boy measuring 145 cm must absorb 1196 KCAL daily, or 329 KCAL per meal (midday and evening), which represents an area of approximately 218 cm ² ; or a circle of about 8.3 cm in radius. This boy can therefore place his proteins and carbohydrates in circle C3, the proteins being arranged in the sector of the first series and the carbohydrates being arranged in the sector of the second series.

The 10-year-old girl measuring 140 cm must absorb 1123 KCAL daily, or 309 KCAL per meal (midday and evening), which represents an area of approximately 205 cm ² ; or a circle of approximately 8.1 cm in radius. This girl can therefore place her proteins and carbohydrates in the circle C2 or C3, the proteins being arranged in the sector of the first series and the carbohydrates being arranged in the sector of the second series.

An IT management unit is adapted to implement a logical IT process which automatically selects the C1-C6 circle to be taken into account when placing proteins and carbohydrates.

This computer management unit can be in the form of one or more processors or microprocessors integrated in an individual computer terminal. This computer terminal can be a fixed or portable computer, a mobile phone or Smartphone of the iPhone®, Samsung Galaxy® type, or another computer terminal operating with an operating system of the Windows, Mac, iOS, Android, etc. type.

Referring to FIG. 3, a computer terminal 3 used in the invention notably comprises one or more processors or microprocessors 30, one or more memories 31, a graphic interface 32, which are mutually connected via a common bus 33. A or several computer applications - or computer programs - are stored in the memory or memories 31 and whose instructions (or codes), when they are executed by the processor or processors 30 make it possible to implement the logical computer process.

The memory or memories 31 must be considered as a storage device also suitable for storing data and / or data files. It can be native memory or add-on memory such as a Secure Digital (SD) card.

The processor 30 and the memory 31 can be integrated into a SIM card (from the English Suscriber Identity Module), the latter being connected to the bus 33.

The graphical interface 32 offers the individual the possibility of entering, selecting and / or entering data or instructions. It is for example in the form of a touch screen, a screen connected to a keyboard, etc.

The individual may be required to install a computer application in his terminal 3 to implement all or part of the invention from said terminal, and in particular the implementation of the logical computer process. This computer application can be preinstalled on terminal 3. The user can however search for this computer application in an online store such as Google Play®, Itunes® or on a dedicated website, and then download them to his terminal 3.

In an alternative embodiment, the individual also has the possibility of connecting his terminal 3 to a dedicated website, the latter directly integrating the management unit adapted for the implementation of the logical computer process.

From the graphical interface 32, the user enters and / or selects his gender, weight, height, age, and data characteristic of his activity

-13physics (ex: <2 hrs / week;> 2 hrs / week;> 4 hrs / week;> 6 hrs / week). These are the input data.

The logical IT process can then proceed as follows:

The management unit 30 first calculates the individual's weight target taking into account his adequate BMI:

Goal Weight (kg) = adequate BMI x Height ² (m)

The correct BMI is chosen according to the sex and age of the individual as described above.

The empirical formulas defined above, then make it possible to determine the daily number of KCAL necessary for the individual. By subtracting a predefined percentage of KCAL, for example 45%, for breakfast, snacks, fats, sugary and / or alcoholic beverages and fruits, vegetable oil or margarine and for vegetables , we obtain the number of KCAL necessary for the individual for two meals. By dividing this number of KCAL by two, we obtain the quantity of KCAL for each meal (midday and evening).

Finally, given that 300 KCAL of carbohydrates and proteins occupy an area of approximately 200 cm ² , a rule of three makes it possible to determine the area occupied by the necessary number of KCALs and therefore to select the circle Ci-C ₆ to take into account (output).

To assess the number of daily KCALs remaining to consume (45% including 5% of vegetables) in the previous examples), the management unit 30 advantageously makes available to the user, for example in the form of a display on the graphical interface 32, a list of food portions comprising a predefined number of KCALs, for example on average around 75 KCALs. This list can notably contain the following foods: egg, yogurt, fromage blanc, soy dessert, chocolate (20g), honey-chocolate paste jam (3 teaspoons), glass of wine (12.5cl), glass of beer (25cl), sugar (3 teaspoons), cheese (25g), almonds-hazelnuts-nuts (12g), etc.

-14 For the adult man in Table 3, the number of daily KCALs remaining to consume excluding vegetables is 40%, or 951 KCAL, which represents approximately 13 servings of 75 KCAL each. It could thus be proposed to this adult man to consume for breakfast and snacks, for example, 2 eggs, 2 bread semi-slices, 2 x 20g of chocolate, 2 fruits, 2 glasses of wine, 1 yogurt. Two tablespoons of oil may additionally be used for seasoning.

For the adult woman in Table 3, the number of daily KCALs remaining to consume excluding vegetables is 40%, or 394 KCAL, which represents approximately 5 servings of 75 KCAL each. This adult woman could thus be offered to consume for breakfast and snacks, for example, 1 half-slice of bread, 1 x 20g of chocolate, 1 fruit, 1 glass of wine and 1 yogurt.

The arrangement of the various elements and / or means and / or stages of the invention, in the embodiments described above, should not be understood as requiring such an arrangement in all implementations. In any event, it will be understood that various modifications can be made to these elements and / or means and / or stages, without departing from the spirit and scope of the invention.

In particular, instead of the circles illustrated in FIG. 1, the bottom 10 of the plate 1 can be graduated with other series of homothetic and concentric geometric figures each defining a predefined surface. By "concentric" is meant that the geometric figures have the same center O; and by “homothetic” is meant that the geometric figures are obtained by homothetic (ie are of the same shape) from their common center O. FIG. 4 shows for example a series of homothetic and concentric squares, and FIG. 5 a series of homothetic and concentric ellipses. Other geometric shapes can be provided, in particular polygonal shapes.

In FIGS. 4 and 5, the segments Ri, R2 have for common origin the common center O of the geometric figures and divide the latter into two

-15 series of sectors. The term “sector” is understood to mean the area delimited by the two segments Ri, R2 and by the portion of the outline of the geometric figures located at the intersection of the two said segments. The angle formed by the segments Ri, R2 is chosen so that, for a given geometric figure of coast, the sector of the first series dedicated to proteins has an area between half and third of that of the sector of the second carbohydrate series. Depending on the geometric shapes, the segments Ri, R2 can be linear (Figures 1, 4 and 5), or curved, or in the form of broken lines.
