What is a calorie? - Emma Bryce 

that is why it is not "you are what you eat", but "you are what you absorb".

What I got from this video. -Calories are units used to measure food energy -good luck finding the rest

can you burn calories by thinking hard

so cute, rounded figures. beautiful design.

You sure don't sound like an Emma

"Good luck finding all of that on a nutrition label" Me: 😑

"good luck finding all of that on a nutritional label" my anorexia: how hilarious

That sarcasm at the end though 😂

That was remarkably complete. I didn't think you'd mention all those factors at the end like enzymes and gut bacteria.

"The amount of calories on a nutrition label doesn't mean that is how many calories you're going to get out of it." For someone who counts calories, this is pretty valuable information for me. I never knew that on most things, you don't get all of the calories listed. I always thought that the amount of calories on the nutrition label is exactly how many calories you would get. 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. So now, I definitely have to rethink how I'm going to count my daily caloric intake.

Wow, I had no idea that calories were so complex. Thank you for sharing this information. I never knew just what a calorie was. You're right, we always hear about them but don't really know what they are so sharing this information is pretty valuable and interesting.

I love how each art style is different in Ted Ed videos

So people are fat because they store too many calories? They are like the Noah of the oncoming famines. While we laugh at them, they are busy preparing for the oncoming disaster. I'm way too high right now.

Actually you forgot to/you should explain that calories comes from proteins, fats and carbohydrates and how those proportions affect our bodies.

Don't you mean kcal?

I'm a health science teacher and I love showing Ted Ed vids to my class. This vid explains it so well and the animations help keep my 7th graders' attention lol

These videos are fucking beautiful to watch

Great video as always, could you guys also make a video on how calories are determined in food? like how do scientist determine a small apple to have 100 calories with 19.4g carbs 0 protein and 0.05 fat and other nutrients? i hope its not too much to ask

Thank you for specifying that extracting energy varies from an individual to another and accordingly to the type of food we eat. Many people get this wrong and become obsessed with calorie counts as it is highly advertised by the food industry. It's better to eat 400 kcal of fruit than 200 kcal of industrial chocolate garbage bar. I suggest for the viewers to watch the video on sugar and how it affects the brain, or even the "fed up" documentary.

Wonderfully explained. Thanks!

Awesome and concise, thanks for this.

thank you Emma and everyone who are behind this video.

Is THIS why I'm so hungry even after a few slices of pizza?

Excellent video! Nutrient dense whole plant foods for the win! 🌱💪

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

Calories is the amount of heat required to raise the temperature of water from 14.5°C to 15.5°C. It's basically a unit of energy mostly used for heat energy.

Now they should make a video on Balanced diet.

Great thing to know - thanks for explaination! Design in the video is lovely - only the question marks seem out of place.

This was clearly explained, Thanks

Thanks for sharing you are so right about that nutrition label

Thanks for this brief definition ❤

Thanks for this video, it really has stopped me being confused about the calorie thing and why some people are thinner etc

The video should have also mentioned Calorie means one kilo calories. Some products mention energy values in kilo calories instead of Calories (with a capital C). Not everyone knows the difference and may end up thinking that a product has 1000 times the usual calories

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

1 calorie raises the temperature of 1 GRAM of water by 1 degree celsius not 1 Kilogram.

"Good luck finding all that on a nutrition label" Hahaha

The way he explained the answer to my question that my biological teacher failed to answer was brilliant," Is the calorie in bio as same as the one in physics?"

I always like the way it's explained.

I've just in calories surplus program, this is really helpful

Key points from the video: A calorie is a measure of how much energy is contained in the food. Your calorie requirement is based on exercise, food type, and the body's ability to process energy.

1:25 i love the way he eats lmfao😂😂

very well explained!

So useful and clear contend🔥 simply great

Beautifully done. Thank you.

I got to this channel by mistake now I can't stop watching. Help!

This is exactly what I talk about in this video: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-MhhODXIdT8E.html

I loved all the information and animations

This is very informative. Clearly paints picture as why as we age our calorie intake should reduce since we are less active. Furthermore explains the importance of excercise.

Does anybody know that "joule" is the metric unit of energy? Earlier in my life, I use calorie, which converts to approximately 4.184 joules. 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.

Beautiful explanation

Thanks for the good luck. I've found all the information I need on a nutrition label

The characters and animals are so cute and amazing!

My excuse is “I have a fast metabolism”. 🙈

Really like these TED talk videos.

This is very helpful thanks mate.

Awesome video! I agree with the information presented.

my anorexia is like “this is so adorable, go head and eat🥰” aha, it’s tricked. whew

thank you very much today you shown me such a good video to batter understand.. i love you who's designed this video... lots of thanks you

This video on a calorie was very informative!

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

AsapSCIENCE: what is a calorie? TED-Ed: we got you

I'm one step closer to understanding. I enjoyed the slow narration. 🎓📖🐒

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

Oh my, this is a very beneficial video! Thanks a lot, I've never known before that the number of calories written might not be the same with the number of calories our body will receive. Around 2 years ago, I used to count calories for almost half a year. Together with moderate exercise, I lost 7 kg. However, once I stopped maintaining a healthy lifestyle, I gain backed 10 kg and it was dreadful. Now I'm trying to get back on track again. This time I'm not gonna count calories. Instead of that, I'm eating more mindfully and trying to become more active in daily life. :')

Fat people: "No, it's just genetics."

3:23 my man smiled while saying people i swear

Now I understand about calories very well Thanks!!!

so to find how many calories something has, you have to harness the energy stored and turn that into thermal energy. How?

Pov: Youre on elementary school and you just got sent by your teacher

very nice explanation

This video answered nothing but added more questions: a good start

This might sound weird, but I can't concentrate the guy's voice sounds warm, smooth and attractive to me xD

It's amazing how the average person has about 12 years of education and still don't understand basic personal finance and basic nutrition. Meanwhile everyone's an expert on pythagorean theorem, the Capulets & Montagues and what every politician did/said in the 17th and 18th centuries.

This video opened new topics for me to search.

Amazing Video! Thank you !

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

As I started following diet and training plan from Agoge Diet, I took my confidence to the next level. Girls finally started noticing me.

Ted you are the best thing ever that has existed in RU-vid 😍

thanks for all this awesome stuff..

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

1 calorie is the amount of energy to raise 1gram of water by 1 Degree celsius. Not 1 kg of water.

Very well explained

Nice explained

Me running out of area 51 with all the nutritions labels

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

Thanks for sharing !

amazing!!!! ty for this knowledge!

In Australia the calorie is being replaced by the kilojoule.

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.

The best video I jave ever seen on the subject!

this video taught me a lot.. thanks

I would love to see an american explain 0:56 using their system

Physically, one calorie is the amount of heat energy required to rise the temperature of 1 gram of water through 1 degree Celsius.

Thank you, Addison!

They really wanted to make full use of the animation that shows the calories in the body. (The two columns, one teal, the other red, with the spinning thing at the bottom.)

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

0:52 So when he says 1 calorie he means 1 Kcal?

So adorable and well explained...

Thank you for sharing :)
