Like a pedometer, it keeps count of a repetitive physical movement. But putting fork to mouth is more complex than walking. "A pedometer can't tell what kind of motion you're making. This tracks a very specific motion," Hoover says.
The wrist rotation necessary to move a fork from plate to mouth turns out to be the critical motion in eating; the machine counts bites with 90% accuracy, he says.
It also counts bites taken without the use of a fork or spoon, such as eating an apple; the rotation of the wrist is the same whether eating with the hands or utensils, Hoover says.See, my problem would be that I seldom use utensils unless the food is messy. I eat a lot of sandwich type stuff, as well. And I take big bites . . so . . . what do the rest of you think? Does this have any value?
Hoover and his co-inventor, psychologist Eric Muth, have found that one bite generally averages about 25 calories. Read more . . .
