Does celery burn calories?


Quote  |  Reply
I've heard your body uses more calories to digest raw celery than you take in when you eat it. Is this true?

Celery is a "negative calorie food".

Simply stated it is a food that you actually burn more calories digesting than it contains.
Above is a link to a brief article explaining this concept along with some other examples of negative calorie foods.

Definitely items to keep handy for snacking purposes :)

Thank you for the info.
there's actualy a lot of debate on this subject.  some people swear its true, others swear it's not!  i tend to disbelieve that anything in life is negative, food related.  the closest you get is water, and that's zero.  i'm not saying that i know for sure though...

instead of thinking its a negative calorie food, just look at the label.  practically zero calories anyway.  either way it's a good snacker :)

celery comes with a label wouldn't that be amazing if all fruits had a special sticker with their cal on it ohhhh wow that would be awesome,  so much for guessing and weighing my fruits and veggies

 This is a myth.  Sorry.  There are no negative calorie foods.

actually its not really a myth

while celery doesn't literally have negative calories, it does take slightly more calories to digest(ie get broken down inside your stomach and intestines) celery than it provides.  This amount is pretty insignificant though.  Same with water, since that provides you with 0 calories, but it takes energy/calories to heat water up to body temperature(interestingly enough calories are actually defined in terms of heating water) so the net effect is that more calories were burned than given by the time it exits your body.

No - Don't believe this.

The whole "this food and that food is negative calories blah blah..." was just a lie made up to scam people into buying the book about it. So yeah, don't fall for it 

while its not significant enough to matter

here are some facts

1. water has 0 calories

2. when you go to the bathroom water is warm

3. it takes energy to heat water

so yes it is 100% fact that you burn calories when digesting water and since water has 0 calories that means the act of drinking cold water would cause your calories eaten minus calories burned to be lower than it would have been if you didn't drink that water.

there is no disputing that, it is a scientific fact

now I have no idea how many calories it takes to digest celery, but considering that we have very limited ability to breakdown cellulose, celery gives us an extremely low amount of calories, so the amount burned breaking digestign it is probably more than we get from that celery.

however again this is a small amount of calories and is pretty insignificant compared to daily caloric intake and calories burned, so yes it doesn't matter, but it is still technically true(at least with water, and probably with celery though I don't know for sure), but you would burn more calories by walking for a few minutes.

I would argue that the heating of the water is passive, not active. The calories are being burned by your body anyway. The fact that the water was heated was more a function of its being in your body. 

You could use the analogy of baking a potato on the engine block of your car. You put the foil-wrapped potato on your car's engine and drive across town and back running errands. Now, how much fuel does it take to cook a potato? In reality you didn't burn any fuel to cook the potato, you burned fuel to move the car around, and the heat to cook the potato was a by-product of the trip you took. 

That said, if you are drinking ice-cold water, your body's thermostat is certainly going to crank up to compensate for the sudden drop in your core temperature. But the same effect can be achieved by sitting in a cold room or eating ice cream. 

By estimates, if you drink 64 oz of ice water (0 Celsius) every day, you would be burning about 70 Calories in order to bring that water to your body's temperature, which isn't negligible. On the other hand, just about any practitioner of Eastern medicine will tell you that drinking ice-cold water is bad for your health.

water is totally negative calorie, especially ice cold water.

energy is always conserve in a system.

 

your body is a system.

 

cold water enters body and leeches energy from body to warm up to body temperature. cells has to consume more energy to warm themselves back up to temperature. water provides no energy (but is necessary for metabolism) 

 

btw, on the car scenario, the potato does make the engine every less efficient by absorbing heat from the engine block, increase temperature gradient across the engine, and thus stealing more energy (heat) from the combustion.  it's just very little that you aren't aware of it).

 

please be aware combustion engine are still around 60% efficiency, with 40% loss to heat, noise, and vibration.

While for argument's sake celery may consume more calories than it contains, the calorie count system treats it as positive calories. One cup of chopped celery contains 19 calories. If you're using this system you count all foods as positive because "living" (or BMR, or activity level) accounts for digestion.  If you're using some other system follow their rules.

Most of the so-called negative calorie foods are good foods to eat.  I'm only slamming the concept because it's confusing.  Some people get the impression that if they eat a lot of negative celery they can offset a piece of cake.

yeah with the car thing... I think 100lb of potatoes would be a better number..  then you can look at the extra fuel that is needed to bring that extra weight up to speed.

long answer yes with an 'if', short answer no with a 'but'

Hi, I'm an engineer with a background in physics, here is a literal scientific truth about the celery.

First some science!  A calorie is a measurement of energy based on the amount of heat produced from burning it.  Fossil fuels, like gasoline and coal were measured in calories until a static baseline for mass to joules ratio was created.  A joule is a derivation of work based on the amount of energy put into task.

Now the truth.

No, it does not provide negative calories.  1 cup of chopped celery contains only 19 calories usable by the human body.  That's pretty low, and tasty.

Yes, the AVERAGE human body uses about 20 calories to digest the heavy fibers along the back of the stalk.  But some may use as little as 5 calories and some may use as many as 30.

So, depending on how you prepare it, uncut meaning you use more calories in ripping those fibers apart with your teeth, not skinning the back, like most people / restaurants do, leaving the heavy fibers there the be chewed and then digested.  And depending on you metabolism and the efficiency of your gastrointestinal system to break down, a suck the nutrients out.

So, for some people it may be a negative calorie food, for some it may not.  It depends on how your eating it, and how your body works.

But the flat scientific fact is that it contains calories, becuase it is a living organic carbon based structure, and is not a negative calorie food, it just happens that it SOMETIMES takes more calories to break down.

No, haha, exercising makes you burn calories :) xx

Holding a glass of water warms the water, that doesn't burn calories. It's the same thing inside the body. It's passive, as someone said.

Seriously? Of all the calories in the world, you're worried about the ones in celery?

I don't believe it but, even if it's true, I cannot imagine it burns enough to make a difference. 

This is a huge myth. Celery is just a healthy, low calorie vegetable that you should eat. It's not going to make you lose any weight, unless of course you snack on it INSTEAD OF potato chips or other high calorie snacks.
