The number 1 fact about obesity is wrong 

...

Hah! :D

Lol ;)

Same

Nice video and great explanations. Science isn't perfect but trends in the research shouldn't be overlooked.

So you want us to feel sorry for obese people or something? We already know some gain easier than others and there's already a body positive movement that could potentially send the wrong message (that being fat/obese is ok). We can acknowledge the science without encouraging people to just lay down and rot. Brb no point in putting in any effort becuz ma jeens

+Bite Size Psych Regarding this topic you can find a great lecture about obesity from Robert Lustig here in youtube. It's called Sugar: The Bitter Truth

+Bite Size Psych For sure genetic plays important role in it, but also environment. cross country, culture, education, value system, real different environment. But I think your video is very interesting, I haven't use my brain on other youtube videos since a while. that means you're doing something good here. and just forget about some primitive comments. to discriminate is actually a part of human instinct, not a very good part in this case.

+Bite Size Psych "Surely genetics can't change fast enough to account for this rapid rise. " What about epigenetics and the case of the dutch famine?

We have terrible food that's designed to taste delicious, but never give you that full feeling. That and laziness

Mr Anderson Could very well be.

that's environmental not genetic. Which is the argument.

For one, genetics don't just controls the results of our attempts at diets alone - it controls us in general on various levels - even our mental states and 'free will'. Some can subscribe to nonstop exercise and reap more profits easier thanks to a greater pre-programmed degree of will and placebo effect. We might all have similar genetics on the species scale per se - but different people will be predisposed to process different things in different fashions. Some might have better metabolism and can drain fat faster even if eating habits are worse to balance it out - others could be more prone to store more fat because of the geographic location of their ancestors. It's important to note that genetic differences CAN emerge 'fast' pe se - especially if one takes into account how many more people there are, how many more people give successful births and how many more people survive to pass down potentially subpar genes. I mean - just breeding a bunch of mice in different environments for a couple decades can grant strains with considerable genetic and therefore observable differences. B6 research strain mice are prone to anger and, IIRC, skin lesions, while BALB/C are prone to allergies due to too much eosinophils but it didn't take us literal eons to create them.

The vid never claimed that obesity is entirely genetic. Rather, genetic vulnerability plays a substantial role in who gets fat first.

Mvp

+Serah Wint Epigenetics deal with how your DNA is expressed and for twins if they have identical DNA then there wouldn't be a difference in expression that is driven by DNA independently. Like you said environment is also a factor, but twins usually grow up together in the same environments and researchers would have controlled for that anyway.

Kyzan Hyuri I guess that's true. But how would you control for that factor? You would have to have identical twins growing up separately or something like that, otherwise they have the same environment and then you don't know if its the environment or the actual genes doing it. maybe I don't think about this right but it seems to me like that would make it really hard to reliably study something like this-

Serah Wint They've done separated twin studies for other traits so I'm sure they can for this. Anyway the path to success requires the mindset to want to improve yourself, even if your genes put you at a disadvantage. If people just accept that it's genetics and resign then they'll never improve.

Kyzan Hyuri "Anyway the path to success requires the mindset to want to improve yourself" That I can get behind.

+Bite Size Psych don't twins usually also have the same environment?

+Bite Size Psych Of course genetics has a role. It can make it easier, or it can make it harder. For me, it makes it hard, I can gain 2 kg a day if I give in to certain lifestyle. It takes a month to lose those same 2 kg. I have to work twice as hard, and I accept it. I don't lay on the couch and stuff my face with junk feeling sorry for myself. The fact that these studies are not mentioned often is great, because their conclusions remove responsibility. And additional removal of responsibility is the last thing obese people need.

+Bite Size Psych well... yes and no, as a skinny person i believe that weight is related to genetics, on the other hand theres the fat guy and then the truly obese guy, and here... is self awareness, education and behaviour it's hardly due to genetics.

+Bite Size Psych If the twins were raised by the same parents, then there could be significant influence of behaviour. Like genetics - it is also mainly caused by parents.

+Bite Size Psych Curse you Darwin foiled again.

+JOKZ 😂

1: Yes, but that doesn't mean much since there's a 55/45 split of gender in the twin couples of the study that indirectly accounts for gender. It's not like all twin couples were one gender. 2: Because we're not living in our natural habitat in any conceivable way. No one biologically profits from the unnatural climate. It's all about receptiveness though. Some people are worse off and others get by easily. That's a big part of the study's scope. 3: You're 100% correct. As previously stated though, it's largely about how the genetic material of certain heritages cope with this new unnatural way of living. 4: Yes, partly because of racial differences. Another explanation might be that some cultures live more naturally and thus the body need not adapt and the study becomes more or less redundant. It's important to be critical. Thanks for your comment.

stop eating 2000cal meals, you are not going to faint if you do. your lifestyle probably doesnt require that much energy and thus you look like a mcmuffin

don trump Nice reply from someone who didn't even read the comment. Also, it should be obvious that 2000 calories was for the day, not a meal. Regardless, any lifestyle for a person of my height, weight, age, and gender (even without exercise) should, by doctors standards, lose weight on a 1200-1400 cal a day diet. According to science, an average person of my size burns over 2.4K cal doing absolutely nothing, just basic human functions. I'll stop there since it's pretty obvious you don't actually give a shit :D

dude that sucks. even though you worked your arse off, you can't seem to have the results that you wanted. it's like life itself is pointless. however, i admire your dedication and simply say good luck.

StarScremerZ Thanks. Trying something different currently. Results are good so far, as they typically are in the beginning. We shall see.

Where I live, everyone accept that people are born genetically different. Yet there's not that many overweight people here, despite the lack of pressure. When you judge people's fitness on whether they train enough/eat healthily instead of how they look, you can really see the difference between those who lack the effort and those who just have terrible genetics.

it also makes them less intelligent and some of your organs shut down so... not a great alternative

If you only cut 20-40% of your maintenance caloric intake (depending on your bodyfat %, if you are fairly slim, you shouldn´t cut more than 25%, or you may also lose muscle mass), it will have no negative impact on your health whatsoever, on the contrary, if you have excess bodyfat, especially around the waistline, it will greatly reduce your risks of coronary diseases in the long run, not to mention make you look better, remove some unwanted weight from your knees, make you more functional in mostly every way and more. Your fat reserves literally only exist so your body can burn them when you don´t have enough food, they are energy reserves, and they don´t need to exceed around 6-8% for men, and around 15% for women in order for you to be perfectly healthy and have adequate hormonal levels. The only alternative is either working out very often and quite long for not so impressive fat loss results (which will do exactly the same thing anyway - burn your fat), or keep putting on more fat as you get older, never cutting back. Good luck with that.

LarlemMagic Ikr, if they were to just cut down on food they would have nothing to create excess fat!

+Fiyaaah Not thought about race?

+Fiyaaah Maybe it shows different predispositions of fat for different human populations. Some east Asian countries use different Body mass index (BMI) then the western countries. The idea being that in these country, obesity related diseases start appearing in smaller indexes for their population than for western populations.

I'll try to explain the confusion. The study cited in the video about genetics being the main factor of obesity is right. The part about genetics affecting metabolism which in turns affects obesity implying metabolism is the main factor of obesity is wrong. You can think of obesity as the result of the mental disease of stuffing yourself. The cause of this stuffing yourself mental disease being a result of genetics explains why the study is right and concur with field observation that what comes in determines how big you get.

This!

_"Well, twins would be expected to act the same given how they look the same"._ dafuq?

+Macavellic If anything this video is anti-McDonalds

+feikkiacco Off base again dude. Saying it was a sponsorship of McDonalds is a hyperbole, but reaffirming peoples belief that their genetics are the main cause of their weight only promotes obesity promoting behaviors, hence helping Mcdonalds. Does that make sense to you?

Actually if we stop shaming people for their actions and start looking at the causes of those actions we might see that McDonalds uses sugar, fat, salt and caffeine to create addictive fattening "food" that drives our brains into completely irrational behaviour. When we see a cause of behaviour we can start to change it.

+VinylUnboxings yes.

+feikkiacco That doesnt change the fact that the video does the opposite of what you said it does.

I'm very skinny too and it's not fun. Being underweight has its own problems, and the fact that I can't eat more than my body lets me means I can't choose my weight.

The always being cold part is the worst part for me. If a cloud passes over the sun even in the middle of summer I start to shiver, like a Sphynx cat in the arctic. My hands are always so cold that I have to run hot water over them a couple of times per day and people often ask me if I smoke. I'd gain a few pounds if I could, and I've tried, but my body won't let me.

LOL gaining weight is the easiest thing ever. I used to be anorexic 3 years ago and gained like 100 lbs of mostly muscle since then because I decided I wanted to change and kept eating till I was nauseous every meal. 3-6 months of eating till I was sick and now I have a big appetite and eat 3500 kcal a day.

thealldaypker In which universe is causing yourself to be nauseous on a daily basis considered "easy"?

KETimiko Or healthy

You don't influence your early childhood diet, so it's to the same effect.

ancalyme Could you elaborate? Your sentence doesn't make sense to me.

+a3rialst4rr What he/she meant was that you have about the same control over your childhood diet as you have over your genetics. Therefore, the effect for the adult is pretty much the same.

sweliam1 But it's not to the same effect. Let's say we had identicals that grew up with completely different childhood diets. I'm sure their microflora, digestion, metabolism, etc would still all be pretty different. However, we would need a study to show this, which we don't have (as far as I know)

fast fucking food

+MassiveDestructionSP lower natural selection pressures

+MassiveDestructionSP I have one. it's left to be proven (and we could argue that it is) #1 when we eat sugars (all types of carbs except fiber), our body cannot store it. That's when insulin levels rise, so that we can use that sugar. The body turns it into glycogen (sugar + water) and stores it in the liver until you need it. Some of it you use right away of course. If the body didn't do that, you'd die. That's basically type 2 diabetes: bad insulin response, sugar levels in blood gets too high. This is basically sugar storing (and fat storing) mode. Only slow activites allow you to burn fat, if you run or do something big, you'll be using the sugar you ate. Here's what happens if you don't eat for days: No sugar is left in your body, so your body starts using bodyfat. Since insulin levels are super low, you're not storing anything (here it is obvious, you don't even have food inside) If you eat once a day (but all the food you need) you'd be burning fat all day and store up only once. This is called intermittent fasting and it's be proven to have great health benefits, one of them is reducing insulin resistance. Not what if you don't eat sugar, only protein and fat? Your body is already in fat burning mode. You are not gonna store the fat, or at least very little of it. Insulin isn't there but food is, but without insulin levels rising, your body doesn't store anything it doesn't need. In fact, the more fat you eat the faster you lose weight in that diet (I have the source - it does not work if you eat sugar at the same time) So what recently changed? "Oh nooooo! The fat we've been eating for centuries is BAAD! Let's come up with that weird sugar thing that we only find in tiny, tiny, tiny quantities in food directly from nature, and make our WHOLE diet be made *mainly* of it!" (note: with diets of slow sugar they've been able to have success at reversing partially or completely insulin resistance - depending on how quickly the sugar is processed in the body, insulin levels don't rise as much. Plus, potatos for example, fill you the fuck up. So all sugars aren't equal although they are sugar.) I didn't post sources yet because RU-vid keeps deleting my comments

+TheGuardian163 A bit wrong mostly right. I won't say much because I waste too much time on comments, but we use muscle first instead of fat and eating lots of sugar helps your chances of type 2 diabetes go up. But mainly spot on yo

+MassiveDestructionSP The differences became more pronounced. You still had fat and thin people before, even in families living in similar circumstances. But once food became more plentiful and jobs less physically straining the difference became much more pronounced.

It's a rational theory.

Being lazy is such a great gene to have when being in the wilderness "I need water.... nah the water will come to me, I must conserve energy." "I need food..... nah the animals will hunt and cook themselves, I must conserve energy." /s. Horrible logic

Im sure laziness had its advantages , much like boredom did (and does)

+popcornfilms1 lazy people think more!

Yes but things like satiety aren't controlled by mitochondrial genes

MaRaX93 This is a good point. I just think it should be noted that the there are assumptions being made about twins here that may or may not be the case.

Yeah, I don't believe you, I bet you've seen plenty of obese people in Pakistan, in the last 20 years? How could you possibly spend 20 years in a country like Pakistan and not see a single obese person? Maybe if you said some island in the middle of nowhere with a tribe of 30, sure, but a country like Pakistan? wtf.

+Sid B why would i even lie about something like this? im in no way saying that there arent obese people in pakistan, im just saying that from my years of living in here ive never seen one personally. though i have seen people who are fat but i wouldn't classify them as obese.

+Maaz ahmed Obesity is based on BMI, not your perception. Its possible someone you classified as overweight was indeed obese

Pakistan has a population of 200M ..So I am assuming you're making this comment after meeting atleast 101M people

+Marc Päpper Think of it this way: some people, to achieve the same look, have to work twice as hard. So while technically it is just a question of practicing enough and having enough discipline, in practice we all work 8 hours a day, and have the same amount of free time, so after while you just say "fuck this shit". It's like earning half the salary for doing the same job.

+Spliter It takes a lot of time to exercise enough to have results, but it takes very little time to simply eat less in the first place. I don't think time is the issue here. Of course genetics makes it harder for some people. But isn't that true for just about anything?

lion.ger well said.

that doesn't make the genetic argument any less true. try again.

AllenQuatermain2de Empty Assertions Incorporated strikes again.

***** the irony is strong, try again.

AllenQuatermain2de There's no irony there. Unless you're actually dumb enough to think that eating too much doesn't cause obesity.

***** the fact that you missed the irony doesn't mean its not there. try again.

What it means is that it could be twice as harder to maintain even a relatively healthy weight for people with this. In order to be healthy one would have to dedicate every fraction of their lives to how much they weigh. Imagine how hard it is for the average person to do this, let alone someone with genes prone to obesity.

I hear you. I'm sure there are people with this sort of disorder, but I'm convinced that this is a very small minority, and that people are using this disorder as an excuse for themselves, even if it does'nt apply to them. Most people who are obese are so for logical reasons - energy in / energy out. You're body can't create fat unless it has a surplus of energy, and most obese people DO consume a surplus of energy - with a perfectly normal metabolism.

Gabriel Ståhl And I agree. I get so frustrated when I see obese people gulping down diet cokes, eating potato chips and fast food and then sitting around with walking canes. Most of them not even 50 years old. People look at these people and think that is how all of us are. I am not one of those people. i try very hard to be active and eat right. I will admit that I do slip up every now and then. For example Christmas and my brithday- I want to have cake and ice cream. Normal people wouldn't gain much weight from that. But I usually put on an extra 10-15 lbs over the holidays and my birthday. I know that many people who are obese make poor food choices - and I would say that is true. But there are a fragment of us who really are fighting to get healthy and we aren't lazy .

Meade Music You'll have to forgive me for not believing you. I'm not calling you a liar, and I'm not saying that you're not struggling... But pretty much everyone who's struggling with their weight claims that thay are at an unfair disadvantage, and I just don't buy it. To give an example from a documentary: A woman claims that she is gaining weight even though she is eating healthy, and trying to be active. She is closely monitered for a few days to see if what she says is true. The conclusion... Although she's eating healthy foods, she is still overconsuming, and therefore keeps gaining weight. Another example: Two female friends - one fat, one thing - they both claim that they eat similair amounts and have the same activity-level. They both persume that the fat woman has a slower metabolism... after a close inspection, the conclusion was that the fatter one of them ate quite a lot more, and that her metabolism was FASTER than that of the thinner one. People have very different ideas of what a "normal" food intake should look like. The only way to really find out ís to actually count your calories for a short period to get a better perception of your intake. Personaly I had problem gaining weight, and it wasn't untill I counted my calories that I realized that I wasn't even getting enough caloies to maintain my musclemass. I also realized how easy it is to overconsume calories by eating the wrong foods. We all know that Ice cream, soda, chips, cookies, candy and junkfood is BAD for us, but it's not untill you really count the calories and put them into your summary of calorie intake that you realize how easy it is to go waaaaaay past your requirements.

Gabriel Ståhl That study is anecdotal. That is just one person. I know lots of women like her anyway. Unfortunately, they really are whiners and complainers who don't want to make the effort to lose weight. I am not one of those people. You assume that all obese people are gluttons who eat nothing but junk food. While I'm sure that is true in most cases, it isn't for all. There are lots of people who eat junk food and consume lots of calories who aren't fat. Granted, it usually catches up with them by the time they reach 40, but still- its very valid argument, that some people really must be vigilant about their diet to the point of obsessive just to maintain a weight that is considered moderately obese I count my calories like a hawk. I get exercise. Even with my chronic fatigue, I have to use caffeine so I can get through the day and stay moderately active. I am still overweight. I do admit yes- I eat junk food. But not on a regular basis. I rarely eat fast food- and I don't even have soft drinks . . I like to have a cookie every now and then because I actually like to live! Unfortunately for some people like myself, all it takes is just 1 extra cookie to gain 2 lbs in a week.

+Dan Reed What is genetic is usually not obesity as such, but rather how well you handle access to unhealthy food. Its similar to how some people are more likely to be alcoholics or drug addicts than others.

+Drakir89 Basically, your metabolism. Except that, unless your metabolism is unnaturally slow (to the point where you just could never lose weight), there are still things out there you can do to lose weight. You could avoid eating unhealthy foods, for instance.

supply of food and the type of food has not remained constant throughout history

+Ohrami I won't even consider processed crap food. More like a death wish.

excuse me but u are ignorant dieting and exercising wont help all there are people like myself who tried them but no fucking result its your fucking job as pharmaceut to give us medication which works and not give us that dieting shit

reported for fatshaming

No. My job is to give you medication the your MD says you need, but when it comes to diet pills. You the patient, have to request it from your doctor, becuase many people who are fat, saying dieting and exercising doesn't work for them or the ridiculous reasons they can't diet and exercise to loss weight. Here's the thing. If it took 10 years to put the weight on. It's going to take almost the same amount of time to take it off. And no. there is not going to be any kind of magic drug that going to take you from 400lb to that of a supermodel and this is exactly what a lot of fat people are waiting for. If you need proof that dieting and exercising works! Just listen to some of the stories with Richard Simmons. Stop using genes as a cop-out. If your fat it's because 2 things. 1. Bad eating habits 2. Laziness

daammnn u fatshaming is searious thing ur facts dont make it more acceptable its easy for u to just say that i need dieting when u are skinny as fuck ...this society needs more plus size models

ok, I guessing a troll.

+OurCognitiveSurplus Think of it not as "genetic obesity" but "genetic vulnerability to an environment that causes obesity". USA has more problems with obesity due to cultural or political factors - but the genetics of individuals decide which persons are affected most strongly by this "pro-obesity" environment.

Viktor Vaughn Not a great summary.

Benjamin Ortola A very great summary, actually. That's all the video really said - everyone can lose weight, but the rate at which people lose weight varies due to each individuals' bodies responding to physical exertion and consumption.

Viktor Vaughn Yeah, that's better than what you actually put.

Benjamin Ortola I said the exact same thing in my original post, with the extension that anybody who is gaining weight or maintaining their obesity/overweight physique is likely not eating properly or exercising at all.

***** >Thinking people are genetically morbidly obese >Thinking that people are genetically fat despite a healthy lifestyle and moderate portioned, well balanced diet >MFW RayLiottaGoodfellasLaugh.gif

A very pessimistic view. How does having empathy for fat people help them out? How does blaming genetics help them out? They can't change their genetics, but they can change how much crappy food they eat and how much exercise they do. Our ancestors didn't have obesity rates as high as we do now, and their genetic pool would have been very similar to ours.

It is stated in the video that ostracism against obese people is harmful.

of course it does, probably even more

Those are ectomorphs.

+StoreBrand its 2016 and people still believe in somatotypes fucking lel.

***** Nope, sorry, what you eat is a choice. It is not genetics. Learning to defer gratification is what being an adult is all about.

***** Yes, the flaw in that is they were working with twins who were also raised in the same environment so they didn't control for that. I don't understand physical laws? So...it IS possible for your body to generate more mass than it's taking in? Yeah, didn't think so. Yes it is "energy in - energy out", deal with it!

Um, you realize peoples bodes react differently, I now eat extremely healthy go to the gym 6/7 days and am very strict on diet, yet my brother who never goes to the gym and eats pretty poorly is skinnier then me and has much less body fat

Erudalty VIden That doesn't change a single thing I said.

My point being that genetics are a huge role and that some people cannot do what others can

That IS genetics...

Actually, no, genetics are strongly correlated to personality characteristics and behavioral traits. If people really want to change and overcome obesity, most of them will probably need to take that into account rather than trying to rely on the simplistic perspective of "just be disciplined."

Winston, genetics have SOME things to do with personality traits BUT they do not control your personality, you can ultimately dictate it through discipline and a strong desire to.

Boredfan Gerrude Nope, research says differently. Genetics is a very significant part of personality. Of course you have conscious choice over individual decisions, but a large part of who you are is not really conscious.

I'm sorry I just can't agree. If that were really the case, people's personalities would be far more similar than they are since we can all trace our genetics back to the same ancestors, white, black or Asian. This is because ultimately, Humans are an inbred race as it's inevitable that even diverse genetics of a species would all meet up eventually in a new generation. But that isn't true, there are billions of different personalities, one for each person.

Boredfan Gerrude "If that were really the case, people's personalities would be far more similar than they are since we can all trace our genetics back to the same ancestors, white, black or Asian." That doesn't make sense because it's like saying that if skin color was genetic we would all be the same color, since we all come from the same ancestors. Clearly, skin color is genetic, and yet, clearly there's a lot of variation in that. "But that isn't true, there are billions of different personalities, one for each person." Of course everyone has their own individual personality. But there are also large generalized trends toward particular personality traits, and there's pretty strong evidence that they're heritable genetic characteristics.

When you make BEING healthier the goal and stop falsely equating thinness with a healthy lifestyle it's a lot easier to stay motivated.

That's how it works! I knew there was some reason why high stress is correlated with obesity, and was under the impression that it was reasonably well studied, but I didn't remember exactly how it worked. Also, either males or females tend to eat more when stressed, right? Can't remember which way it goes though.
