Abstract

A dietary menu planning system. The dietary menu planning system receives personal characteristics and food preferences for an individual. The personal characteristics includes a desired physiological rate of change for the individual. Based on the physiological rate of change and other personal characteristics, a set of dietary constraints is developed for the individual. A dietary menu plan is created for the individual including food items selected by the individual and with quantities determined to maximize the food preferences of the individual while satisfying the dietary constraints. The creation of the dietary menu plan includes applying an optimization function to maximize the food preferences. The dietary menu planning system is implemented as a stand-alone application for a computer or as a networked-system, for example, as a fee-for-service basis through the Internet.

Claims

1. A method of creating an optimized dietary menu for an individual using a computer having a processor, said method comprising the steps of:

receiving personal characteristics and a desired physiological change rate from the individual;

generating a set of dietary constraints based upon said personal characteristics using the processor, said desired physiological change rate, and nutritional profile constraints, wherein said set of dietary constraints comprises a system of inequalities;

receiving palatability scores for a plurality of food items, wherein each palatability score defines the palatability to the individual of the corresponding food item;

generating the optimized dietary menu comprising a set of food items selected from said plurality of food items using the processor, wherein said set of food items is selected so as to satisfy said system of inequalities and maximize a resultant palatability score associated with said set of food items; and

outputting said optimized dietary menu,

wherein said system of inequalities defines a relationship between said selected food items and one or more nutritional constraints, and wherein said step of generating the optimized dietary menu includes determining a quantity for each selected food item and maximizing an optimization function, wherein the optimization function comprises a sum of terms, and wherein each term comprises the product of the quantity and the palatability score associated with one of said selected food items, and wherein the result of said sum of terms comprises said resultant palatability score.

2. The method as claimed in claim 1, wherein, for each of said selected food items, said quantity comprises a serving weight for said selected food item.

3. The method as claimed in claim 1, wherein said system of inequalities includes two or more inequalities, and wherein each inequality comprises a sum of nutritional terms and a relation between the sum of nutritional terms and one of said nutritional constraints.

4. The method as claimed in claim 3, wherein said sum of nutritional terms comprises a sum of contributions of said selected food items to a nutritional variable for which said one of said nutritional constraints prescribes a maximum or minimum.

5. The method as claimed in claim 4, wherein said one of said nutritional constraints comprises a maximum total caloric intake.

6. The method as claimed in claim 4, wherein said one of said nutritional constraints comprises a minimum dietary fibre.

7. The method as claimed in claim 3, wherein said step of generating said set of dietary constraints includes obtaining one or more recommended daily maximums or minimums of particular nutrients from a nutritional profile database, and wherein said one or more recommended daily maximums or minimums comprise said nutritional constraints within said system of inequalities.

8. A system for creating an optimized dietary menu plan for an individual, said system comprising:

a food items database, said food items database including a plurality of food items;

a user interface for receiving a desired physiological change rate and personal characteristics of the individual and for receiving palatability scores for said plurality of food items for the individual, wherein each palatability score defines the palatability to the individual of the corresponding food item;

memory for storing said personal characteristics, said desired physiological change rate, and said palatability scores;

a component operable to generate a set of dietary constraints based upon said personal characteristics, said desired physiological change rate, and nutritional profile constraints, wherein said set of dietary constraints comprises a system of inequalities;

a component for generating the optimized dietary menu comprising a set of food items selected from said plurality of food items, said component being operable to select said set of food items so as to satisfy said set of system of inequalities and maximize a resultant palatability score associated with said set of food items; and

a component operable to output said dietary menu to the individual, wherein said system of inequalities defines a relationship between said selected food items and one or more nutritional constraints, and wherein said component for generating the optimized dietary menu includes a component for determining a quantity for each selected food item and maximizing an optimization function, wherein the optimization function comprises a sum of terms, and wherein each term comprises the product of the quantity and the palatability score associated with one of said selected food items, and wherein the result of said sum of terms comprises said resultant palatability score.

9. The system as claimed in claim 8, wherein, for each of said selected food items, said quantity comprises a serving weight for said selected food item.

10. The system as claimed in claim 8, wherein said system of inequalities includes two or more inequalities, and wherein each inequality comprises a sum of nutritional terms and a relation between the sum of nutritional terms and one of said nutritional constraints.

11. The system as claimed in claim 10, wherein said sum of nutritional terms comprises a sum of contributions of said selected food items to a nutritional variable for which said one of said nutritional constraints prescribes a maximum or minimum.

12. The system as claimed in claim 11, wherein said one of said nutritional constraints comprises a maximum total caloric intake.

13. The system as claimed in claim 11, wherein said one of said nutritional constraints comprises a minimum dietary fibre.

14. A computer-readable medium having recorded thereon a computer readable program including instructions for creating an optimized dietary menu for an individual, said instructions comprising:

computer readable instructions for receiving personal characteristics and a desired physiological change rate from the individual;

computer readable instructions for generating a set of dietary constraints based upon said personal characteristics, said desired physiological change rate, and nutritional profile constraints, wherein said set of dietary constraints comprises a system of inequalities;
