...do you burn when chexing gum?
My guess would be zero or very close...if you're trying to burn calories, the only thing that really does it is exercise. Though household chores work, too, or walking, or running, or playing sports, or even using a nintendo wii & playing tennis or boxing.
Actually chewing sugar free gum is a great way to snack between meals and it works the muscles in your face and helps get rid of double chins :-)
probably, but not enough to make any difference
you burn 11 calories chewing gum.
I'd say a negligible amount.
