Researchers from Clemson University in South Carolina in the US have created a watch-like device that calculates every bite you take while tallying up the calories. Announced August 2, the Bite Counter tracks a pattern of wrist-roll motions to identify when the wearer has taken a bite of food. “Think of it as a pedometer for eating,” states the release. Calories are calculated from bite count based on a formula similar to that found in exercise equipment estimating calories burned. The designers claim the readings are 90 percent acccurate.
