Abstract: A calorie monitoring device is provided for providing a visual output which compares the number of calories burned by an individual versus the calorie intake for the individual. The device has a keyboard which functions as a first input to input the calorie intake of the individual. The calorie intake input is applied to a first calculator through an interface and the calculator adds the calorie intake input to the total calorie intake in storage and displays the new total calorie intake. The keyboard also functions as a second input to receive a value indicative of the calories burned per unit of time for the individual under normal conditions. This value is applied to a second calculator through the interface circuit. The second calculator calculates and displays the total number of calories burned during a total time period which extends over a plurality of the predetermined time periods.
