Abstract: A computer-implemented method of generating a set of goals is presented. The method entails receiving user input that includes items and an input value associated with each of the items. Individual values are assigned to the items based on the input value. The individual values are then summed to generate a total value, and the items are ranked according to the contributions of their respective individual values to the total value. A difference between the total value and a corresponding reference value is determined. The input value that is associated with the highest-ranking item is changed, and the total value and the difference are then recalculated using the changed input value. The process is repeated with the next highest-ranked item and the next until a condition is fulfilled. A goal is defined based on the changed input value of the items at the time the condition is fulfilled.

Abstract: A computer-implemented method of generating questions for a survey is presented. The method entails receiving user input regarding a relevant characteristic in response to a first question, and using the user input and a default item to determine items to be included in the second question, wherein the items are associated with the relevant characteristic and are in a same item group as the default item. The items may be food, and the relevant characteristic may indicate the types of food that may be eaten or be avoided. Also presented is a computer-implemented method of changing a user's behavior. The method entails assigning a user to a team, and allowing the user to earn points for the team by making changes to one's diet and/or activities.
