Description

Slimmer's calculator WEIGHT WATCHERS (UK) LIMITED C.110765 - l - Slimmer's Calculator Field of the Invention The present invention relates to a calculator for assisting a person on a diet.

Background to the Invention Slimming diets have become extremely' popular and many regimes have been proposed- Many such regimes are based on the simple proposition that in order to lose weight,- a person most ear food Having fewer calorifis ihsn she he j requires. The number of calories required by an individual is determined by his/her weight and level of activity. A heavy or active person requires more calories than a light or inactive person.

In order to establish the number of calories that a person requires in a day to support her/his energy demand, a value, termed the basal metabolic rate (BMR), is multiplied by a factor determined by the activity level of the person. The value of the BMR is dependen on the sex and weight of a person and tables of this data are readily available to those skilled in art of dietetics.

When a person is following a conventional calorie intake restriction diet (known colloquially as "counting calories"), his/her daily calorie demand is determined from her/his BMR and activity level- For instance, a moderately active woman weighing 60kg would have a BMR of 5565 kj/ day and an activity factor of 1-3 giving a daily requirement of 7234kJ. In order for this person to lose 0.45kg (lib) in one week, her daily calorie intake must be restricted to 5142k J.

The present inventors have established that merely "counting calorics" is not ideal and that other factors should be taken into account. However, taking into account additional factors requires the dieter to perform more complex mathematics which is difficult in the bustle of daily life.

It is an ?»m of the present invention to provide an apparatus whereby a diet regime, more complex than mere "calorie counting", can be readily adhered to.

Summary of the Invention According to the present invention, there is provided a calculator for assisting person on a diet regime wherein said person is allocated a maximum daily points target, said points being related to the calorific value and another nutritional parameter of food ingested, the calculator comprising means for inputting a first number related to the calorific value of a food item, means for inputting a second number related to said other parameter of the food item, display means and processing means programmed to perform an algorithm so as to process said numbers to produce a resultant points value and to control the display to display said resultant points value.

Preferably, the other parameter is saturated fat content but the present invention is not restricted thereto. For example, the simple sugar content of foodstuff may be used as an alternative or additionally.

Preferably, the algorithm is: c f P = — — where p is the resultant points value, c is the calorific value related number, f is the number related to the other parameter, and kt and k2 are constants.

The value c may be in kilojoules or kilocalories and the constant k, is chosen so that the points target will be in the low tens. Numbers in the low tens are easier for people to deal with than the numbers in the thousands which "calorie counting" involves. If the value c is to be entered in kilocalories, k2 is preferably within the range k 35 to k,/lO, more preferably k 17.5.

However, if the value c is to be entered in kilojoules, k2 is preferably in the range k 146.7 to k2l4\.%, more preferably A/72.8- The values for k7 are based on the assumption chat / is in grams. Suitable scaling factors will be needed if f is in other units. Conveniently, the resultant points value will be rounded up or down to an integer value. However, values in the range 0.25 to 0.74999 may be rounded to 0.5 and values below 0.25 rounded to 0.0.

In an implementation particularly suitable for use in Australia and New Zealand, (where the value c is to be entered in kilojoules and fis to be entered in grams of total fat) k, is preferably equal to about k 37.5. Alternatively, k2 may be in a range of about kt/75 to k(/20.

An alternative algorithm is: = + - - p Jc, * *, *, In this algorithm,/ represents total fat content and r represents the weight of roughage or dietary fibre in a portion of food. If the value c is entered in kilocalories, k is preferably in the range &,/2.5 to kt/l.S, more preferably in the region of kt/2. If the value c is entered in kilocalories, k3 is preferably in the range kt/2Q to kt/5t more preferably in the region of &t/10. The values for kj, k3 and arc based on the assumption that f and r are in grams. Suitable scaling factors will be needed iif or r is in other units.

Preferably, the calculator has an alphanumeric display. However, a purely numeric display could be used.

Conveniently, the processing means is operable to accumulate said resultant points value. In this way, the calculator can inform a user of the points used or still available in a day. - 3a - Prepackaged food in many countries is labelled with the calorie, saturated fat and dietary fibre content and a user need only enter these values as necessar into a calculator according to the present invention. However, when food is sold loose or served in a restaurant, this information, is not available. In order to solve this problem, the calculator may include memory means storing a database of data related to the calorific value and one or more other parameters of a plurality of foodstuffs. Thus, a user will be able to enter the necessary data by identifying the foodstuff and its quantity. - 4 - Brief Description of the Drawings Figure 1 shows a first embodiment of a calculator according to the presen invention; Figure 2 is a block diagram of the electronic circuitry of a calculator according s to the present invention Figure 3 is a flow diagram mustrating the operation of the calculator of Figure Figure 4 shows a second embodiment of a calculator according to the present invention; io Figure 5 is a flow diagram illustrating the operation of the calculator of Figure 4; and Figure 6 shows a third embodiment of a calculator according to the present invention; and Figure 7 is a flow diagram illustrating the operation of the calculator of Figure i> 5.

Description of Preferred Embodiments Embodiments of the present invention will now be described, by way of example, with reference to the accompanying drawings. 20 Referring to Figure 1, a calculator according to the present invention is physically similar to a conventional calculator and comprises a housing 1, a keypad 3, an on/off switch 4 and an alphanumeric display 5- The keypad 3, however, is tailored to the calculator's particular function and comprises keys S 6,.., 15 for numbers 0 to 9, key 16 for the decimal point, a calories (CAL) key 17, a saturated fats (SAT FAT) key 18, a calm late (POINTS) key 19, an accumulate (STORE) key 20, a clear (CLEAR) key 21 and a new day (NEW DAY) key 22.

O Referring to Figure 2, the electronic circuitry of the calculator comprises a microprocessor 25, a ROM 27, a RAM 29, a keypad interface circuit 31, a display driver circuit 33 and a bus 35 which interconnects the active . 5 - components. The keypad interface circuit 31 is coupled to the keypad 3 and detects key presses and norifies the microprocessor 25 of the operation of any of the keys 6,..,22. The display driver circuit 33 controls the display in response to commands form the microprocessor 25. The ROM 27 stores the 5 control program for the microprocessor 25 and constants used in calculations, and the RAM 29 is used to store data input by a user, the results of calculations and intermediate values. The RAM 29 is of a non-volatile type or is provided with power independently of the mam on/off switch 4.

O The operation of the calculator shown in Figure 1 will now be described. In the following, description of the control of the display 5 in direct response to key presses will be omitted for the sake of clarity. However, it will be appreciated that the microprocessor 25 will control the display 5, via the display driver circuit 33, to indicate to a user that a key 6,..,22 has been fully s pressed. Operation of the number and decimal point keys 6,.., 16 will result in the display of numbers in the manner of a conventional calculator. Operation of the other keys will be indicated by a suitable descriptive word, e.g. NEW DAY, POINTS, STORING etc. 0 Referrin to Figure 3, when the calculator is switched on, it performs a self test routine si during which target and current points left values in the RAM 29 are displayed on the display 5 with the messages "TARGET" and "POINTS LEfr TODAY" respectively. If the self test routine si reveals no faults, the microprocessor 25 loops through three keypress test steps s comprising "is the EW DAY key 22" being pressed s2, "is a number or dtn'rnal point key 6,..,16" being pressed for direct entry of points 53 and "is the CAL key 17" being pressed for calculation of points 54.

If it is determined, ax step s2, that the NEW DAY key 22 is being pressed, the o microprocessor 25 performs step s5. At step $5, the microprocessor 25 repeatedly determines whether a numerical key 6,..,1£ is being pressed to enable the user to enter his/her points target for the day. If a key other than - 6 -a numerical key 6,.., 16 is being pressed, step s6 is performed. At step s6, the microprocessor 25 determines -whether the STORE key 20 is being pressed. If not, the microprocessor 25 repeatedly interrogates the keypad interface circuit 31 until it has been pressed. When the STORE key 20 is pressed, the microprocessor 25 performs step s7. At step s7, the microprocessor 25 stores the input points target, or restores the previous value if no numerical keys 6,..,16 have been pressed, in the RAM 29, and sets an accumulated points value, stored in the RAM 29, to zero. The display 5 is then updated at steo s20, to show the messages "TARGET n" and "POINTS LEFT TODAY n -accumulated points value", where n is the target value.

If it is determined, at steps 3, that a number or Arrima point key, that is a numerical key, 6,..,16 is being pressed, the microprocessor 25 moves on to step s8. At step s8, the microprocessor 25 determines whether additional numerical keys 6,..,16 are being entered. Once a key other than a numerical key 6,.., 16 is pressed, the microprocessor 25 moves on to step s9 where it determines whether the CLEAR key 21 is being pressed. If the CLEAR key 21 is not being pressed, the microprocessor 25 determines whether the STORE key 20 is being pressed at step $10. If the STORE key 20 is not being pressed, the microprocessor 25 returns to step s9.

If the STORE key 20 is being pressed, the microprocessor 25 performs step sll where the entered number is added to the accumulated points total stored in the RAM 29. Finally, the target and points left values are displayed at step S20.

If it is determined, at step s4, that the CAL key 17 is being pressed, the microprocessor 25 repeatedly performs a number entry step, step sl3, until a non-numeric key is pressed. This enables a user to enter the calorie value for an item of food. When this occurs, the microprocessor 25 determines whether it is the CLEAR key 21 which is being pressed, step sl4. If the CLEAR key 21 is not being pressed, the microprocessor 25 determines whether the SAT FAT key 18 is being pressed, step sl5. If the answer at step sl5 is no, the microprocessor 25 returns to step S 14.

Once the SAT FAT key 18 has been pressed, the microprocessor 25 performs another number entry step, step sl6. This enables a user to enter the quantity in grams of saturated fats for the food item. At step s 17, the microprocessor 25 determines whether the CLEAR key 21 is being pressed- If the CLEAR key 21 is not being pressed, the microprocessor 25 performs step sl8 to determine whether the POINTS key 19 is being pressed. If the POINTS key 19 is not being pressed, the microprocessor 25 returns to step sl7. If, however, the POINTS key 19 is being pressed, the microprocessor 25 performs step sl9. At step sl9, the microprocessor 25 calculates the points for the food item according to the equation: where p is the points value, c is the number of kilocalories entered and f is the number of grams of saturated fat entered. The microprocessor 25 then causes the display driver 33 to display the points value on the display 5.

In an implementation particularly suitable for use in Australia and New Zealand, (where the value c is to be entered in kilojoules and f is to be entered in grams of total fat as listed on Australian food labels), the microprocessor 25 calculates the points p for the food item according to the equation: - 7a - Another embodiment of the present invention will now be described, with reference to Figures 2, 4 and 5.

Referring to Figure 4, a summer's calculator is substantially the same as the - 8 - embodiment described above and the same features are indicated with the same reference numbers. However, this embodiment is provided with a SCAN UP ke 40 and a SCAN DOWN key 41. These keys are used in conjunction with a database of points values for different food items stored in i the ROM 27 (Figure 2) to enable a user to use the calculator when the calorie and saturated fat values for a food item are not available, for instance when eating in a restaurant.

The operation of the calculator, shown in Figure 4, will now be described o with reference to Figure 5.

The operation of the calculator of Figure 4 is that same as that of the calculator of Figure 1 except for the addition of a step, step s21, to the keypress test loop and an associated routine. If the answers to the tests at s steps s2, s3 and s4 are all no, the microprocessor 25 determines whether the SCAN UP key 40 or the SCAN DOWN key 41 is being pressed- If one of these keys is being pressed, the microprocessor 25 first tests whether it is the SCAN DOWN key 41 which is being pressed at step s22- If the SCAN DOWN key 41 is being pressed, the microprocessor 25 reads the first record 0 from the database in the ROM 27 and causes it to be displayed (step s23). The display 5 will comprise an identification of a food item, a number of points and the unit to which the points relate, for instance BANANA 1 EACH, STEAK 2 100G or COLA 1 100ML. Then the microprocessor 25 returns to step s22.

S If it is not the SCAN DOWN key 41 which is being pressed, the microprocessor 25 confirms that the SCAN UP key 40 is being pressed- If this is the case, the microprocessor 25 performs step s25 which comprises causing the last item in the database to be displayed on the display 5. Then o the microprocessor 25 returns to step s22- If the SCAN UP key 40 or the SCAN DOWN key 41 is being pressed at this - 9 -time, the microprocessor 25 moves to step s23 or step s25 as appropriate.

However, on r i's occasion, the precedin or succeeding database entry will be displayed, depending on which key is being pressed.

If neither the SCAN UP key 40 nor the SCAN DOWN key 41 is being pressed, the microprocessor 25 determines whether the CLEAR key 21 is being pressed. If the CLEAR key 21 is not being pressed, the microprocessor 25 moves on to step s27 where it determines whether a numerical key 6,.., 16 is being pressed. If a numerical key 6,.., 16 is being pressed, the microprocessor 25 returns step s22. Otherwise, the microprocessor 25 moves on to step s28 where it determines whether the POINTS key 19 is being pressed. If not, the microprocessor 25 returns to step s22. However, if it is, the microprocessor 25 performs step s29. At step s29, the microprocessor 25 multiplies the points value for the last displayed database entry by the number entered by the user. The result is displayed on the display 5. Next, the microprocessor 25 moves to step s9.

A further embodiment of the present invention will now be described, with reference to Figures 2, 6 and 7.

Referring to Figure 6, the slimmer's calculator is substantially the same as in the first embodiment described above and the same features are indicated with the same reference numbers. However, this embodiment is provided with a dietary fibre (FIBRE) key 50 and the SAT FAT key 18 is now a FAT key. This key is divided so that a user can enter the weight of dietary fibre in a portion of food.

The operation of the calculator, shown in Figure 6, will now be described with reference to Figure 7.

Referring to Figure 7, when the calculator is switched on, it performs a self test routine slOl during which targets and current points left values in the - 10 - RAM 29 are displayed on the display 5 with the messages "TARGET" and "POINTS LEFT TODAY" respectively. If the Self test routine slQl reveals no faults, the microprocessor 25 loops through three keypress test steps comprising "is the NEW DAY key 22- being pressed sl02, "is a number or decimal point key 6,..,16" being pressed for direct entry of points and "is the CAL key 17" being pressed for calculation of points.

If it is determined, at step sl02 that the NEW DAY key 22 is being pressed, the microprocessor 25 performs step sl05. At step sl05, the microprocessor 25 repeatedl determines whether a numerical key 6....16 is being pressed to enable the user to enter his/her points target for the day. If key other *h n a numerical key 6,..,16 is being pr sseA, step sl06 is performed. At step sl06, the microprocessor 25 determines whether the STORE key 20 is being pressed. If not, the microprocessor 25 repeatedly interrogates the keypad interface circuit 31 until it has been pressed. When the STORE key 20 is pressed, the microprocessor 25 performs step s 107. At step sl07, the microprocessor 25 stores the input target, or restores the previous value if no numerical keys 6,..,16 have been pressed, in the RAM 29, and sets an accumulated points value, stored in the RAM 29, to zero. The display 5 is then updated at step sl20, to show the messages "TARGET n" and "POINTS LEFT TODAY n - accumulated points value", where n is the target value.

If it is determined, at step sl03, that a number or decimal point key, that is a numerical key, 6,.., 16 is being pressed, the microprocessor 25 moves on to step sl08. At step sl08, the microprocessor 25 determines whether additional numerical keys 6,.., 16 are being entered. Once a key other than a numerical key 6,.., 16 is pressed, the microprocessor 25 moves on to step sl09 where it determines whether the CLEAR key 21 is being pressed. If the CLEAR key 21 is not being pressed, the microprocessor 25 determines whether the STORE key 20 is being pressed at step si 10. If the STORE key 20 is not being pressed,the microprocessor 25 returns to step 109. - 11 - If the STORE key 20 is being pressed, the microprocessor 25 performs step si ll where the entered number is added to the accumulated points total stored in the RAM 29. Finally, the target and points left values are displayed at step sl20.

If it is determined, at step sl04, that the CAL key 17 is being pressed, the microprocessor 25 repeatedly performs a number entry step, si 13, until a non-numeric key is pressed. This enables user to enter the calorie value of an item of food. When this occurs, the microprocessor 25 determines whether it is the CLEAR key 21 that is being pressed, step sll4. If the CLEAR key 21 is not being pressed, the microprocessor 25 determines that the FAT key 18 is being pressed, step sll5. If the answer at step sll5 is no, the microprocessor 25 returns to step si 14.

Once the FAT key 18 has been pressed, the microprocessor 25 performs another number entry step, step 116. This enables the user to enter the quantity in grams of fats for the food item. At step si 17, the microprocessor 25 determines whether the CLEAR key 21 is being pressed. If the CLEAR key 21 is not being pressed, the microprocessor 25 performs step sl21 to determine whether the fibre (FIBRE) key 50 is being pressed. If the fibre (FIBRE) key 50 is not being pressed, the microprocessor 25 returns to step 117.

Once the fibre (FIBRE) key 50 has been pressed, the microprocessor 25 performs another number entry step, step sl22. This enables a user to enter the quantity in grams of dietary fibre for the food item. At step sl23, the microprocessor 25 determines whether the CLEAR key 21 is being ressed. If the CLEAR key 21 is not being pressed, the microprocessor 25 performs step si 18 to detennine whether the POINTS key 19 is being pressed. If the POINTS key 19 is not being pressed, the microprocessor 25 returns to step sl23. If, however, the POINTS key 19 is being pressed, the microprocessor 25 performs step si 19. At step sll9, the microprocessor 25 calculates the can press the CLEAR key 21.

After step sl20 is performed, the microprocessor 25 re-enters the loop of steps sl02, sl03 and sl04.
