Negative calories? Does this really exist?


Quote  |  Reply
I recently read an article talking about foods with negative calories.  It claimed that some foods burn more energy (aka. calories) to digest than what they provide, leaving a calorie deficit.  The only one I remember off the top of my head is celery, which kinda seems to make sense, as it's mainly water with some tough, stringy bits that would likely take some effort to digest.  (hmmm... I wonder if the deficit would offset the amount of peanut butter necessary in order for me to enjoy celery... LOL)

But seriously, does anyone know of other negative calorie foods?

I've heard something about really cold water (like slushy water)...   This might be totally off base but I remember reading if you're stranded in a snow storm you shouldn't eat snow to help yourself become hydrated because your body ends up working to warm it up and by the time it's warm enough to be useful you've wasted more calories than you should.  You should save you energy to build a fire and warm the water. 

I'm probably talking nonsense though :)

I've heard he water thing, too.  A friend who went to Weight Watchers said that they were told to drink cold water to burn a few extra calories as your body works to warm it up....

no, negative calorie foods do not exist.

energy=calories

food=energy

if it didnt have energy it wouldnt really be food.

I dunno how true it is either.  but I've heard that green seedless grapes are like that too.  (I wonder if the effect is multiplied if you eat them frozen!!! Wink )

When I was in high school, my ballet friends and I used to do the (horrible-for-your-body) get skinny fast diet for a couple days of green tea, celery, and grapes.  It works, but only because there were only a few hundred calories in and thousands out! 

In theory negative calorie foods DO exist. However, not in the context in which most people think. A "negative calorie" food is something that is so low in calories that it takes the body as much if not more energy to digest it than the food actually contains. This deficit so to speak is already a part of everybody's BMR. For instance, if your BMR is 1800 calories, it is already taking into account the calories your body burns digesting food. Therefore, if you eat 2000 calories of "negative calorie foods" in a day, then you DO NOT have a calorie deficit of 2000 calories. You still ate 2000 calories.

A "negative calorie" food is any food with a high cellulose content, like celery. Your body doesn't have the necessary biochemical pathways to digest cellulose, so few calories are harvested. Such a tiny amount of calories are expended that there really is no benefit from a dieters point of view (though you should still eat them because fruits/veggies are good for you!).

Yes! Negative calories do exist!! :)

I try to eat as many of them as pssible. When you chew you are losing calories,  with everything you do really. So with ngative calorie foods, by the time you swallow you have burnt most if not all of the calries off. Here is a list:

  • Asparagus
  • Apple
  • Beet Root
  • Broccoli
  • Blueberries
  • Cabbage
  • Cantaloupe
  • Cranberry
  • Celery
  • Chicory
  • Grapefruit
  • Garden cress
  • Garlic
  • Green beans
  • Honeydew
  • Lemon
  • Lime
  • Lettuce
  • Orange
  • Onion
  • Papaya
  • Peach
  • Pineapple
  • Radish
  • Raspberry
  • Strawberry
  • Spinach
  • Tangerine
  • Tomato
  • Turnip
  • Watermelon
  • Zucchini

So Negative foods are foods that require more energy to digest than they provide nutritionally. No food can literally have negative calories in the sense of not releasing energy when digested. However, some foods provide very few calories, and the body may use up more energy to digest them than it gains. The result is a net calorie deficit.

Oh and I think its eating them in their raw state, not cooked lol

 Hope this helped :)

 

pineapple? really?


that's so fab, i just ate way more pineapple than i meant to.

Post #5 is correct.

 This post is almost wholly 100% wrong.  I know saying so may lead straight to some kind of flame war, but I hate the idea of people thinking they can eat 6 pounds of pineapple and have it "not count."  While it's true that many of these foods contain good-for-you fiber and other such hard-to-digest compositions, many of them are also filled with starches or sugar, which are very easy for our bodies to process (and they do, with abandon). 

In short, please follow the caloric content listed for all these items on the site.  That is truly what you are ingesting, not any of this "negative calorie" nonsense.

Additionally, the act of digesting food is already calculated into your BMR as part of "your body needs these many calories to function."  So no need to go about trying to figure out how many calories you burned just eating, and trying to log it :P

No one is saying to eat 6lbs. of pinapple lol. But eating a cup full of sliced cucumbers is better than a cup full of anything else. Ask your jenny consultant or Doctor for that matter. These so called "negative calories" do exist. But no they won't offset anything else.

oh bummer

Fruits and veggies are a better choice than candy bars, of course.  But that doesn't mean that eating pineapple or beets or apples result in a "Net calorie deficit".  Sorry #7, but you're just plain wrong.

tealeaf,

I think you are missing the point! The point is eat more fruit and vegetables than the overprocessed foods that are so horribly wrong for your body! This list should include lentil, barley, and other high fiber beans....yes people, in moderation! You know, you could make a fabulous soup or stew with most of those veggies and trust me, you will be full, and with a lot less calories than if you opened up a can of soup! So, negativity is only good if someone is putting junk in to their body, not fruit and vegetables! BTW I started eating 75% fruit and vegetables and 25%lean protien and I have lost 3 lbs. in 3 days! Go fruits and veggies! Oh, and I eat them raw and cooked!
Negative calories - truth or myth?

According to Snopes:

  • Celery can have negative calories.
  • Not due to chewing but digestion.
  • Dont get excited, you might lose a few dozen calories in a day.
  • Takes 3500 negative calories to lose a lb.
  • Benefit is eating it instead of a higher calorie item.

Ok, i read about negative calories before. i have one question. I started lifting weights to bulk up. Now I am trying to cut the fat. I eat about the same amount of calories but I replace red meat with white meat and used the extra calories on more fruit and vegetables. I love fruit and never eat candy. I just bought a lot of grapes and have been eating them like bags of popcorn. Do grapes have negative calories because I read that they do but i noticed all the carbs in grapes. Will I get fatter or will it benefit me?
