Abstract: A computer database includes information enabling display on a screen of a plurality of objects, in successive groups, together with display of graphics associated with each group. The graphics enable a first user selection of one of the objects of each group and a second user selection related to the object selected by interaction with the screen display, using conventional mouse, touchscreen or other techniques. The user selections are stored in a storage medium so as to generate a database of user choice information from which a behavior analysis is performed. The user selections may comprise food choices and evaluation of enthusiasm, and frequency thereof, whereby a dietary behavior profile is produced. Diet training may then be coordinated by display of a meal and providing the user with the ability to estimate nutrient content as well as participate in interactive adjustment of food items and portion sizes.
