Fat is an evolutionary advantage. It allows us to store a lot of energy in relatively dense packages; gram for gram, fat is the most efficient way to store energy in our bodies.
But don’t get it twisted, fat is more than just a storage center, it’s an ever-changing organ that contributes to our wellbeing.
In today’s Human, we’re not talking about dietary fats like the ones from oil, butter, or meat. This video focuses on fat as adipose tissue, a collection of different cells that we have in different locations in our bodies. This type of tissue is made of endothelial cells, a few immune cells, but mostly a special type of cell called adipocytes.
In every gram of adipose tissue, you’ll find anywhere from one to two million adipocytes.
And it might surprise you that fat cells aren’t passive structures. Adipocytes are living, metabolizing cells with structures like nuclei that hold DNA.
But most of an adipocyte’s body is a storage site for lipid, the energy storage we’re so interested in.
We have approximately 30 billion fat cells, and when we store some excess energy, the cells will grow in size. Then if they can’t grow anymore but you still need to store energy, you’ll grow new fat cells so you can store more energy.
Humans have visceral fat (the type of fat you’re used to seeing that lives in the abdomen and surrounds your internal organs) and we have subcutaneous fat, a fat that exists under the skin.
Find out all the ways these different fats work to support your body and help you function day-to-day in this Human.

Just like literally everything in our body, nothing is inherently bad, but moderation is required to prevent harmful accumulation

I feel like this series is the only thing Seeker does with any depth at all. Their space and physics videos are all surface level and leave a lot to be desired.
*Sebastian Elytron*
I’ve always felt that their space videos were above the surface level.... but to each their own. ;P
Spacetime for physics and space, Scott manley for space vehicular news.
@Bob S Anton for science news.
I can see why you feel that way, but at the same time, I appreciate the fact that they try to make it appealing to people who may be put off by larger topics. It builds interest without scaring off the casual viewer (like myself), PBS does the same. Most people have some understanding of the human body already so it’s easier to be more in depth, I think, but space or physics 😳😳
Still: all things in moderation.
Including moderation itself.

Can you believe some people are lab grown now?
The phrase "That's largely why diets are pointless." was so completely incorrect it hurt. Diets are to train the body to use the leptin to better regulate the accumulation of visceral fat.
You said we didn’t give fat a proper chance to amaze us?!!! I’m amazed every day brother. Look around you!!! Too much.
Lol😂
"Diets are largely pointless." I don't know , I've seen friends go from overweight slugs to very toned people. I will concede that they also exercised, but I believe my point still stands decently enough. Though it is a very interesting thing you have said.
Diet is definitely NOT pointless. You can lose lots of fat even without exercise if you stay in a caloric deficit.
@@CanariasCanariass I think the video meant diets as in those X-week plans where you only eat meal substitution bars and shakes. The people that try those just do the diet, lose some weight, stop the diet, regain the weight. The yo-yo effect in action. If you want to stay a certain weight you need to be able to sustain that diet long term.
@@Tinky1rs
Yeah I agree. You are 100% correct!
All the hefty people should stop putting thiccc on their tinder bio's and start putting evolutionarily advantaged
Except "thiccc" women are not fat at all, just a certain body shape. Science proves that body type elicits the greatest sexual arousal among men. They're sexy and they know it.
For a short time util you get a heart attack
Lmao people saying they're "thicc" when they weigh 400lbs
oh lawd the evolutionary advantage is comin
*_E v o l u t i o n a r y T h i c c_*
This seems like a justification for being overweight. I am overweight myself. Despite the fact that fat is necessary, and its existence is the result of some amazing adaptations, that does not mean that being overweight is not a net negative from a health perspective.
Of course, engaging in self-hatred is bad. So don't do that either.
Lmao yeah this video isn’t about being overweight at all
@Keadin Mode - Perhaps. I've become hypersensitive to the use of science in the service of politics in recent years.
@@massman1216 - It's about how wonderful and underappreciated fat is.
Keadin Mode He’s probably referring to the fat acceptance movement and “body positivity” for fat people
@DerangedGod - I agree.

I can already hear the 600lb fat acceptance people approaching, claiming this video proves they are not unhealthy
Fat acceptance people are like flat earthers, they try and ignore the studies that prove their narrative false although fat acceptance people are more dangerous because they advocate for an unhealthy lifestyle (I'm not fat shaming and there's nothing wrong with a little weight, my message is about the 600ib people)

Being fat is horrible for your health, well being and energy but people need to stop judging them harshly.
Either look past the fat and get to know the person for who they really are or help them in a positive way to lose it.
Dopamine, advertising, lack of money, willpower, motivation and making fun of to me are the top 6 reasons American's are so overweight and obese.

So we can actually hack our body to create leptin when we hungry so that we don't snack excessively, huh? Wait, i make it sound weird😅
Wow !very inspiring☺
I loved this video. It has me wondering how our body burns or loses fat through exercise. Do you think we can have a follow-up video on that subject?
this is a pretty in depth "how" but it may not be in laymans terms

Hi seeker
Another interesting human episode..
Learned lot about fat and its uses..
Patrick kelly explained in simple manner..
Thanks seeker and patrick for educating...🙏👍
We need to learn more about how to take care of our bodies. I knew diets don't work but now I know why exactly. I can't say anything about losing weight since I have an athlete metabolism but now I want to know more about metabolism and exercise and how they counter fat and obesity.
Good shiz man
I would like to this chance to inform people that while the skull and muscle of the head play a key role in face shape, fat pads of the face play just as big a role to the shape of your face and making it unique from others.
Fat is probably the only thing without feedback mechanism in our bodies as this mechanism was never required, we could never become too fat to harm us and not absorbing food you ate (the simplest feedback mechanism) would be a blasphemy to organic efficiency and nature's waste-recycle protocols (eating food only to shit it). On the other hand, muscle tissue is the most regulated and heavily suppressed and could be our savior, as it raises the required calories to maintain weight, making fat gain harder and harder to achieve the more muscle you have. A GDF-8 receptor modulator/blocker could be a promising, possibly risk-free prevention/assisted treatment to obesity. Since its more and more difficult not to gobble down great amounts of calories and it's harder and harder to lose them after gaining them with our bodies clenching on them more and more each time we lose them, we could at least force our bodies in a composition to need them.
Wait what? THE MICE WERE STITCHED TOGETHER??

sugar is the enemy.

If you've yet to read it, I strongly recommend y'all check out The Big Fat Surprise by Nina Teicholz, which highlights the myths and facts about (saturated) lipids. Spoiler: Saturated fats aren't the enemy.
IN marine mammals, what type of fat is blubber, white or brown, or is it a different type of fat?
Is this supposed to make all the quarantined people who have let themselves go, feel good about themselves?
R u from star wats
ok, for a second i though they were going to try and say that being fat is ok. instead they just talked about how fat works, which is cool. I'm taking my angry rant hat off... this time.
The suffix "-cyte" does not mean that the thing you're talking about is a living, metabolizing cell. Dead adipocytes are still adipocytes, even if they don't metabolize anymore. In the same way, a erythrocyte (red blood cell) can be argued to not be properly alive anymore, as it lacks its nucleus and hence can't produce any new mRNAs or proteins, they can only make new or repair old stuff as long as it takes the existing mRNAs to break down and then they're done. A "-cyte" is simply a cellular structure, full stop.
Thanks, I'll tell my girlfriend she's not fat she's the pinnacle of human evolution!
Hope you survive the mass extinction event after that XD
So I'm still 36 pounds overweight but I lost 132 pounds last year. The body will try to adapt to a diet. It will try. But it can't win.
That title is gonna make *fat* people happy lol
*One more excuse for not going to the gym.*
Yay corona
Not gonna lie those mouse experiments are pretty disturbing.
Yup, I'm full of energy 😂✌️
Please don't give me reasons to lay on my couch all day long

This video gave me a lot of different feelings.... from beginning to end. It was a trip. 👍

"Babies are useless"
ROFLOL... Best thing I've heard on UA-cam all day. Seeker wins!
And again. Cool video. But may confuse people. Not deep enough about ketosis
in my experience i found carbon cycling and HIIT to be a good method of loosing fat by tricking the Leptin to think that i get enough calories in a day or throughout the week
I am well marbled too, so my cats have a tasty meal when I croak...
I am right now storing energy into my body
next week: "How Does Diabetes Give Us an Evolutionary Advantage?"
Yeap, that is actually true with Type 2. It ensures during prolonged hunger, your blood will still have enough glucose for brain to function. Your brain can only run on glucose. Elite athletes rarely get Type 2 diabetes even if they have the genetics for it. Their training and lifestyle keeps it under control.
Moderation is the key, ladys and gentlemen.
My bmi have always been on 18.50. 193 tall and love running. So never been an expert when it comes to fat.
Hi, can you please make a video about obesity? Thanks!
Goal achieved ;)
i wish more humans evolve to store less fat as food is literally everywhere since the IR.
the problem now is we’re still clinging to bodies that are fit for hunt gatherers in the Stone Age
.
humans:new software,old hardware
People love to hear good news about their bad habits ;)
Thank you mice... I'm sorry!
I love this context-driven approach to explaining biology! Very intuitive and logical. The presenter also has a great presentation style
Diets aren't pointless. I lost 40 pounds by eating less i was just hungry for 8 months
I think he meant certain types of diets but he should have clarified that. Of course it is much easier to eat less than workout more.
This video is for education and enlightenment of the wonders that have laid upon our bodily canvas, it however does not justify the reason why you should be unhealthily fat and take into account what this video is intended to convey. (Note that I am heavily side ranting and really enjoy this video, thank you all and have a nice day 😊)
Jesus Christo, the mice stitching experiment is horrifying. Imagine that done with humans, or even just dogs, cats... Inb4 human centipede jokes
I would have enjoyed the video if it wasn't for the ridiculous amount of ads. Very disappointed
Very educational video, but it was such a flippant thing to say about how diets are pointless🤦♂️
I love these totally brutal mice experiments. I want to be an evil researcher someday. OMG send me your mice 'cause I just got a totally f*cked up experiment idea!
So how does the whole "calories in = calories out"* thing work? Or is that just a myth?
*Simplified
WTF! JOINING MICE TOGETHER! That is just super messed up!
very sad
Mice centepede
I volunteer my fat for this stem cell research
I am super thin with fat content less than 7% naturally (meaning no matter how much and what I eat I don't get fat at all). And I feel like because of less fat content it has made me more self-conscious because of my thinness. People think something is wrong with me but there isn't anything wrong with me. Its all genetics :/ Sucks a lot.
7:44 keeping carbs to a minimum and increasing fats gets you into keto, probably the only “diet” or method that regulates body fat once you’re body is used to using fat for fuel.
👍
Why can't we turn Adipose cells into cells that can make insulin for diabetic patients,then inject those into the diabetic? You can use the patient's own adipose cells so there will be no rejection issues. Make it so!
Fat is like Iron man reactor, if you use it is actually a good thing.
He man How do you use it exactly?
@@Rokaize if u wake up you dont eat for about 5-6 hours, u only drink water and ur body will be consuming fat as a meal !
then eat a nice meal later
*Phew*
This video makes me feel a little better for being a lazy fatty during quarantine
Damn I’ll cheers to that.
With milk tho not with wine
you shouldn't though.. fat bitch
I guess this guy is an A.I. being tested and used in youtube XD

Morbidly obese people: UNLIMITED POWWWERRRR!!!!
So cool thx
Idk how this video is somehow upsetting some people. He's not saying that you should become obese just that body fat has more than one purpose...
Is it possible to get a self treatment for diabetes type 2?
Remove processed foods and oils and see if that has an effect.
Eat according to your government agency's recommendations regarding food. If you still have issues, definitely go the doctor for more personal advice.
then Naura is one step ahead of the rest of the world in matters to evolution
Nice video, you are too cute Patrick 😻
something is wrong with the audio
I'll be excited when I can store some of that fat outside of my body.. preferably with minimal effort. Which is probably why I want to store it outside of my body in the first place? Hmm
I've loved your episodes, but I find the general glossing over of ketosis in this and the previous video potentially harmful. I understand the limiting factors of time and wanting to give exposure to pervasive knowledge, but I do believe that the fact that insulin is the only hormone that signals the creation of triglycerides, and while most brains growing up with the defunct food pyramid run only on glucose, there is no harm and may be benefits to running on ketones ought to be mentioned before the use of fat cells as a potential source of stem cells (exciting as it is.) I say this because ketosis as a tool often gets written off as people cite videos like this as proof that it can't work. i.e. "the brain runs exclusively on glucose except when you're starving." It's just frankly not true.
Good video. But that part about diets not working is not true at all. I learned around 50% of the info in this video while losing 70 pounds in a year's time, and It was that information that helped me do it. I don't know if this is a part of that whole being over weight is natural movement but when people use information like this to say that theres nothing you can do about being it really obese bothers me.
Fat gives you an advantage at the buffett! Being wide means you can occupy more space in front of the buffett, laying claim to more food realestate!
Then why obese people and animals have so many issues with health? According to his talk, they should be super healthy. He didn’t mention any norms in the amounts of body fat.
Someone listening to this video jokes: "Your mama sooooooo dense, dude!"
yea fat isn’t necessarily bad...but don’t be fat, you’ll have a lot more
energy and vitality overall if you just take care of yourself.
As a Biologist, hooray for finding a new source for stem cells, but oh hell no at creating Siamese twins out of mice. I completely understand the need for animal testing, but THAT, I think, is pushing it.
If ifats not an enemy then it should leave us alone
Lmaoooooo look who they used to tell us about it 😭👀
They played you big homie
Isn't stem cells created from fat cells locked to growing only into another fat cells? Diffently than others types of stem cells
You can make unipotent stem cells or pluripotent stem cells. Naturally, pluripotent has more uses.
Say that to my crush who think being fat means I am the last person she would choose
Yeah, conscious control over fat-buildup/-burning would be nice tho.
Why you tiptoed the the liver fat sir?🤔
Get excited we’re learning about fat
I bet he sent this vid to his wife/gf asap 😂
What is the opposite of obese? And can we get some videos on the effect of being skinny?
Purely physical it's called being underweight or emaciation.
They are just snacks for our body
