The programmed pocket computer determines the quantity of calories in a food product and is fed with data covering weight, volume or quantity of food product. It contains a programmed list of products, with corresponding quantities of calories per weight, volume or measurement, enabling the calorie amount to be calculated. The pocket computer can add up these calculated calorie quantities of different food products during a specific time or deduct them from a pre-set value.
