What is a calorie? - Emma Bryce

We hear about calories all the time: How many calories are in this cookie? How many are burned by doing 100 jumping jacks, or long-distance running, or fidgeting? But what is a calorie, really? And how many of them do we actually need? Emma Bryce explains how a few different factors should go into determining the recommended amount for each person.

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

"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

[MakeMeThinkAgain]

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

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.

"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.

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

[Mostafa-rqrm]

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.

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

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

[ZVEKOfficial]

These videos are fucking beautiful to watch

[bombaa]

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

[mirtagpa]

Awesome and concise, thanks for this.

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.

[tre-moon-dous]

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
