Is there any truth to the notion of “negative calorie” foods?

Question by Æscgifu: Is there any truth to the notion of "negative calorie" foods?
I've read a few websites that claim some types of food use more calories when being digested than they actually contain and thus create a calorie deficit.

Is there any scientific evidence to support this or is it (perhaps misinterpreted) bunkum?

Yes, some foods such as celery are negative calories. They burn more calories digesting then you get from eating it.
