Abstract
Abstract An electronic digital readout diet scale for measuring and displaying weight information. A microcomputer is used to enable a dieter to enter a diet program having an objective weight and a given time interval. The scale will indicate the amount of weight to be lost or gained in order to achieve the objective weight as well as the deviation between the current weight and the projected weight according to the diet program.
