Plate weighing device 'can curb childhood obesity'

"A talking, computerised weighing device that tracks how quickly food is gobbled off the plate could be a solution to childhood obesity, researchers say. The Mandometer keeps tabs during meal times and tells the user if they are wolfing down meals too fast - a habit experts have linked to weight gain. In a trial with 106 obese children the gadget showed promising results, the British Medical Journal reports online. After 12 months of use the children weighed less and ate smaller portions. Their speed of eating was reduced by 11% compared with a gain of 4% in a comparison group" - BBC
