I heard that sucking - not chewing- on an ice cub can burn up to 100 callories(depending on the size), and I know it burns some callories, but I'm not so sure if it's actually that many. hope that helps!! good luck

I think that's pretty much impossible. Walking about a mile burns 100 calories. Sucking on an ice cube or eating celery? I'm guessing 10 calories?
