Thank you so very, very much for making this video. I'm glad I finally know this stuff now because like I said, I had no idea that you don't always get all of the calories that's listed on the label.

Well since it’s the total amount of calories the food contains you at least know what the maximum calories you will get from it are. So if you’re counting calories in order to stay below a certain amount, you can be certain you’ll get as much as is on the label *or less*. The key being that no matter how your body is wired you can’t get more energy than exists in the food.

Thank you for specifying that extracting energy varies from an individual to another and accordingly to the type of food we eat.

[@frosted1030]

There's also metabolic efficiency to consider. Your body changes, adapts to whatever you are doing with it. So the more you physically do, the more efficient your body becomes. This presents a large problem for the media that wants to sell you diet garbage. The media likes to tell you the exact opposite of how your body works, saying that larger people have slower metabolism. This is flatly false. A basic physics equation W = Fs (work equals force over distance). The more something weighs, the more force it takes to move it over the same distance given a specific interval of time. What this means is that large people require more calories to do the same amount of work as smaller people, and thus, they have to have a higher metabolic rate. An athlete can utilize smaller amounts of calories to do the same amount of work because their body has physiologically changed to become more efficient. That being said, chemically there is a *HUGE* monkey wrench in the works called hormonal state. The balance of hormones like testosterone, estrogen, cortisol and epinephrine can drastically change metabolism. Estrogen is a real killer, it promotes fat storage, and fat storage in turn.. produces more estrogen. Cortisol (caused by emotional and physical stress) enables the dreaded belly fat storage. And here's the kicker, with enough testosterone, you can burn your fat stores, build muscle and you don't require as much work and calories to do it. In short, there's a whole lot to this that the diet industry tries to make you ignore. They push diuretics (and call it cleanse) which stresses your kidneys, and any weight loss is water weight. They add stimulants too (and say it gives you energy). Here's the kicker, they use caffeine as their active ingredient. That doesn't work because: 1. Your liver and kidneys "cleanse", and they don't need anything special to do it. 2. Water weight is needed, your body is 55%-75% water and fluctuates frequently. 3. These are unregulated supplements, quality, purity, and consistency are *not legally mandated.* Recently some supplements have been analyzed and found that they do not contain what they advertize. well.blogs.nytimes.com/2015/02/03/new-york-attorney-general-targets-supplements-at-major-retailers/?_r=0

[@pennezita4095]

Wow, thank you so much for sharing!

[@Caaro99]

"A basic physics equation W = Fs (work equals force over distance)" that's incorrect. W = force x distance. Not force over distance. "The more something weighs, the more force it takes to move it over the same distance given a specific interval of time" That is correct except for the time part. Work has nothing to do with time, what you're confusing it with is Power. P = W/T (power is work done over time). We can replace Work with F*D so we get P = F*D/T and then we can replace distance over time with speed and you get Power = Force * Speed. Everything else you said was correct I just had to nitpick on the physics and math lol.

@@Caaro99 I would disagree with you. He said work is equal to force over a distance. This is correct. Force applied over a distance is equal to work. More specifically, it is the dot product of the two vectors - distance and force. So when they are in the same direction it is Force multiplied by the distance.

I have learned on the internet that outside of the United States, joule is the medium measurement of energy, not the calorie. For instance, 200 calories converts to 836.8 joules, or by rounding it to the nearest ones: 837 joules. That is a good lesson about teaching people how to be very precise with eating food that has contains joules of energy.

Large calorie refers to 1kg of water small calorie to 1gram

[@alphaapple1375]

Does anyone know that there is another unit for energy called the joule? The joule is an SI derived unit named after James Prescott Joule. 1 calorie converts to 4.184 joules, while 1 joule converts to 0.239 calories. I am very mindful of what I eat and I want to scale down my craving for some unhealthy food like potato chips, pizza, and soda. In practice, I use joule instead of calorie, or more precisely, kilojoule over kilocalorie. The United States does not display how much joules on nutritional labels, and a lot of people are more familiar with calories. I also use metric units like kilometers and kilograms.

This is the absolute ideal body. You may not like it, but this is what _Peak Performance_ looks like.

[@SwasthyaNeer]

The animators had real fun animating this.

[@ericy03]

Correction: one calorie is defined as to raise one gram of water one degree Celsius

They obviously meant kilocalories, as indicated by the basal metabolic rates suggested for both women and men (2000 and 2500 respectively) earlier in the video.

[@michaeldavis2531]

Yes... But he was referring to the Kilocalorie or "Large" Calorie.

[@aem870]

I finally understand what is a calorie. The other definitions were confusing, this was clear.

[@Ashbury2193]

In Australia the calorie is being replaced by the kilojoule.

[@Physionic]

Do you know why?

[@Ashbury2193]

The kilojoule is part of SI, the official metric system used by most of the world. That's why we are changing.

[@Physionic]

Ashbury2193 Cool, thanks for the info!

[@The1996Bs]

Yasin Omidi That’s incorrect. Watts are defined as Joules/seconds

[@blackwood5851]

Not true, here in the Netherlands we use the metric system too and yet in all food packages you see calories beside kilojoules. Imo calories are easier and should be kept

[@nikilragav]

If you're trying to maximize muscle protein synthesis, you want a lot of the proteins to go to your muscles. Your body theoretically can break apart (metabolize/"burn") proteins for energy, but you don't really want that, right? Is the calorie extracted by your body from protein essentially zero then?

[@pygmal]

I am afraid you are mistaken. 1 caliorie -> raise the temperature of one GRAM of water by one degree Celsius at a pressure of one atmosphere. 1 kcal --> KG of water

[@kellypaton2626]

That's why he said a large Calorie, not just a calorie

[@ganeshrhegde7351]

In this video, it's said that calorie is energy to raise 1degree C temperature of "1 kg water". Actually it is "1 gram water" not a kilogramme.. Please check and gather a right information and clarify me..

[@NeeSan4]

one gram for small calorie one kilogram for large calorie

[@thewalieffect9817]

Everytime i watch a ted ed video my mind blow up Edit: thanks for no likes at all

[@spenzr6920]

***Note*** 0:58 its actually 1 *gram* of water by 1°C not 1kg.

[@tristanmoller9498]

I like to convert calories into Jules and then see how many weights I could lift to a certain height with that amount of energy, to make calories more understandable. After having heard that the energy required to access the chemical energy in the food can differ, which I guess of course it can, the direct conversion probably doesn’t apply.

[@zyaicob]

A fine idea. The unfortunate nature of reality has stricken it down, but a fine idea.

[@chase4786]

So still, I´m confused on HOW exactly Calories are stored inside my food. How is the energy stored in the molecules making up an apple. And how does my body get it out of there?

[@mikbok6750]

yep - good point - they are only trying to say - look we have a number for you so you can make exact calculations - we burn it and boiled it and this much heat is produced - haha great. It's an absolute nonsense. Same with chlorophyll - it absorbs Suns energy - yes maybe - but we can't mimic that or see it - we can only see and enjoy the outcome, and measure that for our own satisfaction.

[@SanJ1e2v]

Food are made up of molecules so calories are stored as the chemical bonds in those molecules

[@D1210]

Beautifully done. Thank you.

[@adamyasingh3713]

I'm confused, celery etc requires more energy to digest??? Means longer time too? More then processed potatoe chips?

[@mohammaddimaporo4828]

yeah! "cycling in the tour de france!!" :)

[@heshamalgebalee2293]

Still I dont get the relation between the energy needed to heat up water calorie and the energy content that the food contains calorie ....well unless if it means that the calories in food measures how much energy u would need to spend to get rid of the calories u just ate, In that case then I guess it would mean that in order to get rid of 3 calories u would need to do enough work that would heat 1 kilogram of water by 3 degrees (someone help me confirm this or sth idk)

[@Han-nk3io]

That called thermic effect of the food ie the body will took amount of calories to digest foos.

[@Paraclef]

You can't burn fire, right ? You can not burn calorie then.

[@HaharuRecords]

This video is supposed to be so informative and helpful but it ends up very confusing

[@imature0117]

The only thing I understood from this video is that calories provide energy :|

[@wesleylance8221]

If this level of explanation is too confusing, the problem is on your end.

[@tokyyo9384]

M.D Records this is a school assignment for me and I don’t get the questions cus this video is so confusing to me

[@brookemears914]

Cristian Țițeica - Please read my comment and see if it helps you understand calories.

[@brookemears914]

tokyyo - Yes the video was confusingly fast paced. Please check my comment and tell me what you think. I’d appreciate it!

[@yaseminyhn711]

hi thank you for your sharing but ı have a question. you said "fibrous foods like celery and whole wheat take more energy to digest, so you'd actually wind up with less energy from a 100 calorie serving of celery than a 100 calorie serving of potato chips" ı didnt understand there, ın that case how is it possible to digest fibrous foods with less energy than potatoes?

[@dogangures1540]

Me running out of area 51 with all the nutritions labels

[@lucaslayton3974]

Addison, please narrate all future videos!I love your voice.

[@matthiasm9591]

You US-Americans should really learn to use the term kilocalorie, because that is what you mean, not calorie.

[@VojtěchJavora]

Matthias Muster I can have 9,000 calories just from a cookie

[@mikebrannon1550]

Us US-Americans, many of us at least, understand a calorie is really a Kilocalorie, we just don't use the term.

[@bruthafromanothamutha7372]

Serious question: One portion of the oatmeal I like to eat is 40 grams (this is dry weight, I assume). The label shows that this is about 26 g carbs, 2 g protein, and 0.5 g of fat. So what is in the other 11.5 g???

[@hubub2475]

Fibre, vitamins, naturally occurring salt, minerals. That sort of stuff.

[@uknowispeaksense7056]

and water

[@weirdboi3375]

“GO EAT MORE FOOD! WE NEED TO MAKE A SUN ON EARTH!!!”

[@Kb-zj4nq]

Question, if a food has let's say 1000 calories and 100 grams of carbs (4 calories per gram), does the carbs increase the total number of calories in that food?

[@hdhdhndjdhdhdhdh4297]

[@potatoskins465]

'good luck finding that on a nutrition label though' xD

[@katemcmanus8861]

XDDDDD RAWR

[@arturomedina2055]

In order to increase the temperature of a 1 Kg of water by 2 degree celsius, do I need 2 calories? If yes, then, can a slice of bread increase the temperature by 75 ºC?

[@SanJ1e2v]

They made a mistake there I think it's not kg it's gram
