It is a dieter’s blessing – or nightmare: a specially programmed calculator that keeps track of the calories you eat.
The pocket-sized Diet Deal calculator was invented by Israeli Yaffa Golan, who said some 130 companies from 35 countries have expressed an interest in marketing the device.
The calculator is pre-programmed with the number of calories found in more than 400 food products; it also keeps track of cholesterol, sugar and protein levels in the foods.
The user programs his or her daily calorie allowance, and then records every item eaten.
The calculator then keeps track of how much more can be eaten that day – and emits a warning beep if the dieter goes beyond the calorie limit.
