Abstract: A system for providing on-demand directed diet advice is provided. A dieter computer communicates with a server. The server receives dieter characteristic data input at the dieter computer and stores the dieter characteristic data. The server also stores diet advice data files and associated data files characteristics. The categories of the data file characteristics substantially correspond to the categories of said dieter characteristics. The server compares the data files characteristics with the dieter characteristics in response to a request by the dieter at the dieter computer. The server transmits an advice data file to the dieter at the dieter computer when the data file matches at least one dieter characteristic.

Abstract: A system stores nutritional information for a variety of foods. A user, interactively connected to the system, via the Internet or the like, accesses the system. The system stores user characteristic data including current weight, diet characteristic information. The dieter inputs their daily food intake to the system. The system monitors the natural diet over a predetermined time, the length of time being sufficient to determine the natural eating patterns of the individual. As a function of the goal, the server ranks the foods eaten in order of worst to best for achieving the goal. The system compares the worst food to foods of the same type and suggests an alternative food to be included in the diet, which is more in keeping with the diet goal. This process is then repeated until the diet is sufficiently modified to achieve the diet goal.
