how much calories does a stick of celery burn?

That’s actually a myth. Celery has around 4 calories a stalk, but you only burn 1-2 eating it.

There’s actually argument as to whether celery is a negative calorie food or not. Some people say it takes more energy to digest it than its worth, some say that it doesn’t. I haven’t seen a difinitive scientific study on the matter, so personally, I’m not sure. Either way, you are consuming or burning a pretty negligible amount of calories.

Caloriecount.about.com says that there is one calorie in the average celery stick, or 19 calories in a cup of chopped celery. However, some scientists say that foods high in fiber, such as celery, might actually have less calories than that. Personally, I count each stick of celery as one calorie even though I accept the possibility that they actually are negative calorie foods, because I’d rather be conservative in my estimation. Then again, I am 5’4 and weigh 100 pounds, so what I’m doing seems to work.

So, in summary, there really is no possible way to get an exact answer in how many net calories eating celery gives you unless you get out those test tubes and conduct the experiments yourself. Either way, I would just eat as much celery as you want and count it as a small amount of calories.
