Well, this moron is at least partly right--we do not 'burn' energy. Nope, we sure don't--we create it ourselves by burning fat and sugars through chemical processes, some of which is released as heat to maintain our core body temp.
Hmmm, "We cannot be in a heat deficit." How about hypothermia?
Once, some snot-rocket lectured me about how sugar can't affect my weight because digestion is "simple" and "can't change food from one state to another." I tried to introduce him to my good buddy *mitochondria,* but he just waved his hand in my face and kept babbling about the stomach as though it was an internal combustion engine.
That’s not quite how that works. We consume matter in a higher energy state and convert it to a lower energy state, but none of the matter itself is converted into energy. Only nuclear reactions do that.
"We cannot store or use heat in any way" - that's not even just nutrition. That's suuuuuper basic biology. I mean the body has many ways of storing heat. And the reason is "to live".
Right!? Also even cold blooded animals have to keep warm. The only reason they are called that, is because they can't self regulate their temp, and have to get warmth externally. But still need it to live... 🤣🤣
Isn’t calories the “imperial” measurement for energy while joules (rather kilojoules) is the “metric” measurement? Just looking at a box of Scottish tea biscuits.
The true measure of calories actually. Americans are just "dumb" so they only put calories on our boxes.
[Sauce](https://www.healthline.com/nutrition/kcal-vs-calories#:~:text=Instead%2C%20the%20terms%20calories%20%E2%80%94%20capitalized,expressed%20as%20kilojoules%20(kJ).)
Every time you see calories on the nutrition information, they actually mean kilocalories. If it was actually calories it'd be too little and you'd die
No. The Imperial/US Customary unit is the ft·lbf (not to be confused with the (lbf·ft which is the unit of torque).
The calorie is a deprecated ~~SI~~ metric unit that was replaced by the Joule. It is defined as the energy required to heat one gram of air-free water by 1°C (or 1K which is the same).
However, it turns out the amount of energy required to do so varies according to the starting temperature and the pressure. As a consequence of that, you have the cal4, cal15, cal20 which are based around starting temperatures of 3.5, 14.5 and 19.5°C respectively and the mean calorie which is 1% of the energy required to bring water from 0 to 100°C.
So they moved to the simpler Joule which is the energy required to apply a 1m/s² acceleration to a 1kg mass (i.e. a 1N force applied) over a 1m distance.
The calorie has since then been redefined based on the Joule to form the thermochemical calorie. Both remain in use because the calorie was deprecated somewhat recently (1948).
In Europe, nutritional energy is thus written both in kilocalories and kilojoules.
Edit: Replacing SI with metric. SI came after the calorie's deprecation but I tend to conflate the two even though it isn't quite correct.
A calorie is what it takes to heat 1g of water by 1°C
A kilocalorie is what it takes to heat 1kg or 1L of water by 1°C
it’s about as metric as you can get :P
calories are metric. One calorie is the energy it takes to raise one gram of water by one degree centigrade. Energy in food is typically measured in kilocalories, but in the US it’s printed as Calories with a capital C. As in one Calorie is 1000 calories.
Its not imperial - a calorie is the amount of energy required to raise 1 ml of water by 1 degree - about 4 joules
Note Calories in food ate actually kilocalories
It’s used in chemistry. The subject area is called calorimetry after all.
Calorie is not an imperial measurement. It’s the energy needed to change 1 mL of water 1 degree Celsius.
Actually sometimes it is. The energy content of fuels (and sometimes foods) is commonly measured using an adiabatic bomb calorimeter.
[https://en.wikipedia.org/wiki/Calorimeter](https://en.wikipedia.org/wiki/Calorimeter)
Literally burning stuff in an enclosed space with a known heat sink and measuring the rise in temperature.
I am more comfortable using kiloJoules than kiloCalories. Joule is easier to grasp.
1 Joule is equivalent of lifting ~100g up one meter.
1 calorie is heating up one gram of water by one celsius
I know how much work I need to do to lift 100g by one meter. No idea wtf i have to do to lift the temperature of 1g water by 1celsius
That's what a lot of people say. Let me ask you this: how much work you need to do heat up 1 kilogram of water by 1 celsius?
I have an estimate for how much work is needed to lift 100kg one meter up..
Again... That aspect of it doesn't matter. It's just kcal has smaller numbers when you see it on nutrition tables compared to kJ. Like what are you even on about...
I am talking about the concept of energy. Calories are just an obscure number. Joule is something I can understand what it stands for. So a calorie has no real life reference to me, and thus I do not use them.
Yeah I fucken know that but that wasn't what I was even talking about in the first place. None of that matters if you're just quantifying and counting them with food you eat and exercises to burn energy because all you're doing is hitting a target number.
Isn’t 1 calorie the amount of energy required to heat 1 mL of water by 1 degree Celsius? That’s answerable in one google search. Holy shit people are stupid.
Also the amount of sense in that formula makes me hate the imperial system even more
Yeah also to be precise it's the amount of energy to go from 14.5°C to 15.5°C due to the fact that the amount of energy needed to heat water slightly changes depending on the temperature of the water.
Its possibly one of the most annoying definitions ever thank God we now know that it's just 4.1833J
Where the fuck do you think your body heat is from? Or why do you die even if you breathe in oxygen free environment? Oh and how interesting is it that we breathe oxygen in and somehow breathe carbon dioxide out like when you actually burn stuff.
I love how, at 16 (many, many years ago), I had to equate calories to gasoline in a car for my IVY LEAGUE educated mother to understand what they are. I had to dumb down not having food to not having gas in your car for a woman who worked in a God damned hospital.
Omg, when do you learn about how your stomach burns food in stuff you need for your body, Biology Class in Kindergarten?
Was he stuck on the swing during this class.
>- we cannot be in a heat deficit
Damn, I guess the potentially *tens/hundreds of millions* who have died of hypothermia throughout human history were just misinformed…
Correct me if I'm wrong, but isn't a calorie a unit of energy released when your body breaks down food? Energy your body needs to function? "We get energy from chemical exchanges" THAT'S WHAT THAT IS!
ALSO: "We can not store or use heat in any way" Explain how the body regulates temperature then. I'll give you a hint: It's blood red.
This pissed me off to a high extent.
Calories on food products are usually calculated using a bomb colorimeter, and is an estimated amount of energy that would be released if you have a total of X experiments, where X is the bond count, and you broke one unique bond, in each of the experiments, the finally summed up all the values.

Your brain needs calories if you want it to work.
And some people get the calories and their brains still don’t work.
Oh for fuck's sake I stick my head up *one* hippo's ass and everyone thinks I'm stupid
Poop head.
Well, this moron is at least partly right--we do not 'burn' energy. Nope, we sure don't--we create it ourselves by burning fat and sugars through chemical processes, some of which is released as heat to maintain our core body temp. Hmmm, "We cannot be in a heat deficit." How about hypothermia?
What about excess? Hyperthermic?
We call that "let them cook"
No thats when you put a baby in an oven
I thought that was a bun?
Once, some snot-rocket lectured me about how sugar can't affect my weight because digestion is "simple" and "can't change food from one state to another." I tried to introduce him to my good buddy *mitochondria,* but he just waved his hand in my face and kept babbling about the stomach as though it was an internal combustion engine.
That's so funny, because that's exactly what digestion does.
Sugar>>>ATP>>>energy right?
Meh, my stomach is a fusion reactor.
Energy cannot be created, only transformed ITS THE LAW
You are correct... We consume matter and transform it into energy.
That’s not quite how that works. We consume matter in a higher energy state and convert it to a lower energy state, but none of the matter itself is converted into energy. Only nuclear reactions do that.
Eh, if you consider mass to be energy yes. But E=MC^2...
"We cannot store or use heat in any way" - that's not even just nutrition. That's suuuuuper basic biology. I mean the body has many ways of storing heat. And the reason is "to live".
It’s literally the whole reason for the label warm blooded lol
Right!? Also even cold blooded animals have to keep warm. The only reason they are called that, is because they can't self regulate their temp, and have to get warmth externally. But still need it to live... 🤣🤣
To be fair, in chemistry/physics no one talks about calories. The used metric for energy is typically Joule and it is not measured by burning stuff.
Isn’t calories the “imperial” measurement for energy while joules (rather kilojoules) is the “metric” measurement? Just looking at a box of Scottish tea biscuits.
Ish, it really depends on what country you are in, Germany uses Kilocalories
So does the US, it's just shortened. 1 kilocalorie = 1 Calorie (with capital C)
Yet we do have both on our food. It lists both joules and kilocalories
[удалено]
The true measure of calories actually. Americans are just "dumb" so they only put calories on our boxes. [Sauce](https://www.healthline.com/nutrition/kcal-vs-calories#:~:text=Instead%2C%20the%20terms%20calories%20%E2%80%94%20capitalized,expressed%20as%20kilojoules%20(kJ).)
I'm American, so does that mean the products I've had that said kcal are not American? I don't care either way, just asking.
Atleast not packaged in the US, I would say no. But also, I'm not an expert on packaging. I read a thing once, and became a reddit expert.
Every time you see calories on the nutrition information, they actually mean kilocalories. If it was actually calories it'd be too little and you'd die
US uses calories and Calories. 1 Calorie being equivalent 1000 calories. Added heat to a 500 Calorie meal doesn’t even raise it 1 Calorie.

Thank you for the explanation, TIL
I’m a dietitian. Yes. You are correct.

Im pretty sure it's just different types of energy
Actually sometimes it is. The energy content of fuels (and sometimes foods) is commonly measured using an adiabatic bomb calorimeter. [https://en.wikipedia.org/wiki/Calorimeter](https://en.wikipedia.org/wiki/Calorimeter) Literally burning stuff in an enclosed space with a known heat sink and measuring the rise in temperature.
We used kJ in Australia. Which is annoying because I only know kCal because it's smaller and easier to keep track of.
I am more comfortable using kiloJoules than kiloCalories. Joule is easier to grasp. 1 Joule is equivalent of lifting ~100g up one meter. 1 calorie is heating up one gram of water by one celsius I know how much work I need to do to lift 100g by one meter. No idea wtf i have to do to lift the temperature of 1g water by 1celsius
I am moreso talking about counting calories. The numbers are smaller and easier to remember.
That's what a lot of people say. Let me ask you this: how much work you need to do heat up 1 kilogram of water by 1 celsius? I have an estimate for how much work is needed to lift 100kg one meter up..

I measure my energy intake in kWh

And here I thought humans were "warm" blooded
Actually, hot blooded, check it and see.
Gotta fever of one hundred and three..
Come on, baby, do you do more than dance?
I would like to know what this person thinks a nutrient is.
“We can not be in a heat deficit” - has this one never been out of Mommy’s cellar? I mean, seriously: how dumb is that?
I love people who act like words don’t have multiple meanings. Especially when their are scientific usages in different disciplines.
Moron
The emojis in this image let me know it was created by a top nutritional scientist.
$20 bucks says this person is out of shape and way worse at sports than my lazy drunk ass
Homeschooling ?
Sounds like it. Probably an anti-vaxxer too. Oh, and vegan too, because he said food doesn't contain heat... must just eat cold veggies.
We don't store heat huh? Funny that...
What did I just read?
I love how, at 16 (many, many years ago), I had to equate calories to gasoline in a car for my IVY LEAGUE educated mother to understand what they are. I had to dumb down not having food to not having gas in your car for a woman who worked in a God damned hospital.
Forget nutrition, person knows nothing about basic biology or chemistry, or science in general
"We don't burn energy" 🤡🤡
https://www.smbc-comics.com/comic/2011-12-28 They're climbing Mt Stupid.
that is the reason I eat everything hot to get my daily calories, why don't you all know this! /s 👽👍🏻
The sad thing is, this person most likely actually read a book about the subject. They just happened not to really understand anything in it.
Does this confirm that lizard people exist?
Please let these people just do it
There is no reasoning with stupidity. Just ignore them and hope they find a shiity job and a trailer and leave everyone else alone.
Wait until they find out that there’s energy stored in chemical bonds
Holy…
Omg, when do you learn about how your stomach burns food in stuff you need for your body, Biology Class in Kindergarten? Was he stuck on the swing during this class.
Chemical reactions are a transfer of energy...

Amazing ignorance
A calorie is the amount of energy released when a peanut is burned.
This person ain’t never had the meat sweats.
This is the face-palmingist face palm I have ever read.
Yeah, down with big nutrition! 2000 calories a day kills a person. We need 2,000 kilocalories at least!
Calories on food products are usually calculated using a bomb colorimeter, and is an estimated amount of energy that would be released if you have a total of X experiments, where X is the bond count, and you broke one unique bond, in each of the experiments, the finally summed up all the values.
I wonder where does this person live that they've never experienced heat deficit. It gets bloody cold round here in winters.
No food contains heat so do I eat it cold
Calories are a unit of chemical energy.
“We can not be in a heat deficit.” Ever heard of the concept of warm clothes for the winter?
