Negative Calorie Foods

Is it all just BS, or is there some truth to it?

Some girl asked a nutritionist this question in class. Apparently there are no such thing as "Negative Calorie Foods." But some foods like celery have such a minimal amount of calories, supposedly it takes more calories to digest it than you can get from it.

Eating strictly these foods would be a bad idea though, celery is good way to curb appetite and add into dishes but eating it as a meal is pointless.

I believe it has to do with foods that take more energy to digest then they offer. Celery is the only one I know of.

yea i had googled it earlier, and there was quite a long list of diff. fruits and vegies. I have heard about celery, but the others i still am kinda skeptical about.

Calorie negative, is not a food thats a black hole vortex, that when you eat it, it sucks a portion of your belly into it.


Its basically food with LITTLE or NO calorie. Food thats just FIBER. What happens is you lift your arm to eat it, you chew your mouth to eat it, and your stomach and intestines spend energy to move it down until you poop it out. These all take energy. If the energy expenditure of eating is greater than the energy gained from the food, the result is a negative delta in calories.

It really is no different than eating a chocolate bar really slowly, and running 5 miles during the process of eating it.
