Abstract

A calculator for use in calculating the appropriate caloric and/or carbohydrate value of a food or drink item that is to be consumed by the user of the device is disclosed. The calculator utilizes a modified four-basic-function calculator of the type having the functions of addition, subtraction, multiplication and division. This basic calculator has been modified by adding a plurality of first contacts to the calculator which visually indicate alphabetical letters and are connected to numerical contacts in the standard calculator. A plurality of second contacts are numerical in function and indicate pre-determined food and drink items and are electrically connected to the calculator circuit while a plurality of third contacts are multiplier contacts and have located in proximity thereto indications of pre-determined alphabetical letters which correspond to caloric and/or carbohydrate values of varying portions of food and drink items. A fourth contact is electrically connected in the equal circuit of the standard calculator and indicates the wording "calorie" or "carbohydrate".

Also disclosed is a novel method using the novel calculator whereby the calories and/or carbohydrates of a given food and drink item may be quickly determined without resorting to pages and pages of printed material relating to the various values. As a modification of the basic invention, there is disclosed a modified calculator in combination with a weighing scale mechanism, the scale having an exposed dial indicating varying combinations of alphabetical letters.
