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.
