BMI for individuals - bit useless....but for whole schools - perfect unless it's run by Prof X 😂
Hey @marklewisfitness what happened to your Apple watch videos? Can't seem to find them anymore 🤔
@@pifko87 should still be up - try looking in the playlist for gear reviews.
@@MarkLewisfitness How odd, I can see them now! Thanks
always hard to tell from Jen's face if she's just really engaged or a captive
My BMI is too high, 27.5 which makes me overweight. This tallies with my waist measurement and body fat percentage. Yet people say "oooh you don't look overweight?". That's because being overweight has been normalised. Unless I get my BMI down to 22 ish, I will continue to be a rubbish runner. BMI is spot on for 99% of people
I spent many years being told I look fine while being very very fat 😂
BMI being high doesn’t make you a bad runner… BMI doesn’t take muscles into account. Look at Nick Bare for example… I am sure he also not average in terms of BMI.
Jen's face when she said daily mail🤣.
You are spot on. A colleague, who is not a bodybuilder, gave the whole BMI is flawed speech, after seeing the doctor.
The thing that gets me is why don't these studies also measure waist size, just to shut these people up. Yeah, The Rock might have a 30+ BMI but he doesn't have a 44 inch waist spilling over his trousers
You got to remember most of the people saying this are the same people that always say "I would do anything to lose weight" but then keep sitting.
There's an Australian comedian who lost quite a lot of weight and he says "People are always saying to me, 'What did you do Pete? Because I've tried everything!' and I say to them 'Really? Tried diet and exercise?' "
I reckon it is the unregulated six year old sumo wrestling scene in the north that skewing the data
I genuinely think waist-to-height is a better method in determining if someone is overweight. BMI is reliable for some people but not everyone
New video title: Jen's eye roll has its place in assessing Mark 😂
People hate the BMI because they will cling to any excuse of not listening to 'You are 'overweight/obese'. But but...bodybuilders!
In my company health fair they have dropped using the BMI chart and have been doing the waist measurement instead.
I LOATH BMI. My daughter was “underweight” and the doctor basically wanted me to force feed a toddler. I had food available to her all the time. She was growing on her own curve but it wasn’t good enough. She ate when we was hungry and stopped when she was full and I didn’t want people messing with her listening to her body. It got to the point they wanted me to hospitalize her for a month for feeding therapy. I said no leave her alone. She is developmentally doing what she is supposed to be and runs around like a normal kid. She is just small. Giver her certain foods and she will eat a ton of it.
I have had a similar thing where the bmi said that my daughters were overweight , and they defonatly are not they are the skinnyest little thing going there, just heavy 😂
I used to think that BMI was biased against taller/stockier people, and then revised my opinion when I got my BMI below 25 and was still a bit chubby. Much more focussed on VO2 Max now ;o)
BMI besides as a macro level metric is also useful for healthcare professionals as a screening tool to help develop more focused plans. A medical professional shouldn’t however just say “your bmi is too high” but it does narrow down what you may say to someone before you see them. Also while the over 25 bmi can be skewed a bit for someone with a lot of lean body mass, it’s fairly reliable for people who are underweight which is generally speaking way more problematic for patients in hospitals then someone a bit overweight.
"Looked a little bit bouncy" 😂😂😂😂
Actually there are studies… BMI underestimates obesity compare to actual MRIs.
I enjoy this type of content from the channel. Good to mix it up.
Population studies are actually the one place BMI *should* be used. That's literally how it's defined. If a large population has a high average BMI, that population is likely to suffer increased amounts of weight-related health issues. It's not saying any particular weight is good or bad, it's saying that you see those health outcomes more once BMI of the population rises.
Using it on an individual is wrong, that's not what it's for. Anyone saying that is technically correct, and we all know that's the best kind of correct. But saying you shouldn't use it for population studies? That's just stupid.
Just checked my BMI on the NHS website, because of this.
6 foot 5; 11 stone 7. BMI of 19. Low end of healthy. Happy with that.
Extremely underweight
@@DUBLL100 unless they're running marathons or a competitive cyclist etc...
This is the inherent issue with society in general. "I don't like the actual reality, so the metrics are obviously wrong." We're doomed.
Glad to finally hear this from someone else's mouth, tip top as always.
Bodybuilders and rugby player can be overweight. Doesn’t mean fat, but your body is only supposed to carry so much weight. Your heart size will increase and so on. Why does overweight just mean too much body fat? (To the people who use the Rugby bodybuilding argument)
This! Love it. BMI in my mind inhabits a place near bodyweight on a shelf of numbers that are great to utilize, but terrible to get hung up on. Doesn't matter if you treat them as the end-all-be-all or "totally useless because body builders." Both groups are hung up in unhealthy ways. Props for pointing out a situation where BMI works really well.
100% I "KNOW" I am currently 2 - 2.5 stone overweight. I feel that weight on me. I have been for some time. That excess weight puts me in the overweight/slightly obese range. I am not a rugby player, never have and never will be. Yes I am stocky and short but still I am overweight and need to lose a bit.
It was interesting to see DEXA scan professionals breakdown a bodybuilders body composition. They even plotted out his skeletal weight. It was quite heavy, ie the weight of his bones.
That's another myth and was confirmed by DEXA that yes although skeletal mass and density can vary in humans the difference in terms of KG's between someone with light bones and heavy bones is like 3-4 kg difference. So don't just say "I am big boned" as a reason for being 20-30KG overweight"
Oh man you got “the look” at the end 😁
Enjoy the channel, thanks 👍🏻
Tbf rugby is quite popular in places like Wigan and Hull 😂
Hip waist ratio is far better.
Can you hand the microphone over to Jen on your next podcast, I feel she may have a lot to offer?!
Is that the news theme from “The Day Today”?
Will look forward to the ballerina fitness challenge vid. Whilst they’re very slim, I bet they’re super fit.
BMI has its placein the whole health arena, but its one of many metrics which adults need to take account of regarding their fitness and lifestyle. Resting HR, minutes of activity. Recovery time from exercise is a big positive which is rarely mentioned. Does it take you 5 minutes to get your breath back after a 10k or the whole day for example. BMI in children is really important to curb bad habits and help grow true understanding of your body and food intake. Of course if we can remove influencers and such from the world that would be a btter thing in my opinion (SPoiled rich kids with nothing better to do). Great video form you both again, keep it up. FYI I didn't throw up when rowing but I did prove my co-ordination really sucks. Practice required.
My biggest issue with BMI is the fact that insurance companies use it to jack up your life insurance premium... Also, measuring circumference (around the naval) has been shown to be a better indicator of good/bad health
Is it not that everyone up north is shorter 😂
I've come to the conclusion that BMI is as good a metric for me as any, because a) I'm not especially muscular, and b) all the other fat measuring methods are rubbish, aside from looking in the mirror, which is also rubbish if you suffer from body dysmorphia, which I don't. I see precisely the good parts as good and the less flattering parts as such. So, a combination of BMI, looking in the mirror, and just noting how I feel, this is the way.
But, yes, as with any fat measurement attempt, make sure BMI always comes with the attendant caveats.
Just have a hyrox photographer follow you around you'll soon see the BMI isnt lying bit weird to have in schools though
But isn’t there some circular reasoning around BMI?
The only reason BMI currently works at a population level is precisely because the population as a whole is unhealthy.
If you had a healthy population, BMI would because a useless measure, both at a population level and at an individual level.
I.e. the only reason we can say that a high average BMI shows the population is unhealthy, is that we already know the population is unhealthy.
Um, no? What?
Funnily enough, poor zipcodes in the US have BMI that trend larger than wealthy zipcodes. My understanding of the research is that healthy food is expensive and hard to find in poor areas, causing people to rely on processed, calorie dense/nutrient deficient processed foods.
Of course. Same as there being a signicantly higher concentration of fast food outlets in poorer areas of... everywhere, but definitely Sydney.
Is that oversimplifying though? Could it also come down to nutrition education, time to take care of yourself, etc? Eating healthy isn't expensive, eating good healthy is different than expensive organic. Being overweight is eating excess calories.
en.wikipedia.org/wiki/Food_desert@@RATM1971
@@Some-Guy-again, greatly oversimplifying, every poor zipcode is not a food desert. I grew up in a poor zipcode. I can tell you a ton of nutritious food was available, people just didn't like to eat it. It's way easier to grab fast food or some processed item.
30 years ago he would have had a point regarding fat rugby players who were semi pro, and where drinking post game was part of the culture .
Modern rugby players are in superb shape!
Dude... No.
He is absolutely not using the logic of Rugby players being fat. He is using the logic that rugby players are not "BMI optimal", because they're muscley. Very few muscley people fall within the healthy BMI range. And that's the point the idiot in the comments was trying to make, but with school kids.
You say you were scrolling through the daily mail and then you say daily mail readers are stupid (no arguments here), were you trying to prove your own point? 😅
I like to know what the lunatics are thinking 🤣 Keeps me one step ahead 😂
Key phrase he uses is "population metric." Exactly what BMI should be used for.
The doctor told my brother, a national-level judo athlete with 10% body fat, that his BMI was problematic.
Has a distinct whiff of Alan Partridge
I agree - but she’s my wife, so it only seems fair to allow her on the podcast.
I work in the industry and I've always backed up BMI. As you say Mark, if your confirmation bias is that it's not a good metric, it probably means that you need to look at what you're doing rather than not being accountable!
I am completely average and bmi works for me.
You are absolutely correct- as a population metric BMI is a useful statistic for reaching generalised conclusions regarding public health. The issue is that so many who quote statistics don’t understand how a particular statistic works to support or refute an hypothesis. As someone once wrote “There are lies, damned lies and statistics.”
And the problem that those who know how statistics work use it against people to push their agenda.
I see all to often that the headline is that X has 3% more risk for Y. And that if you actually read the research its statistically insignificant, so it proved absolutely nothing. You could argue it proved that X has no risk at all.
But still the headlines are used to misinform people.
@MarkLewisfitness
I agree with you. Saying the BMI is no good in a child obesity study because Bodybuilders / Rugby players have a high BMI is rather daft.
However, there is a real problem with BMI as a population metric. It is NOT height invariant. Meaning I often see people using it for instance for comparing obesity rate in men vs woman. That result is always going to be schewed because of the inherent average height difference.
For the same reason your BMI mark will always come out high.
We could use waist to height ratio, which is actually more telling and just as simple to calculate...
Your absolutely correct. It a great population statistic. But many insurance carriers are using it to set rates. The military uses it to determine that a rambo like marine it to fat. Even my company uses it to tell if I'm fit enough to drive. That's where it's rubbish.
BMI is pretty good as a public health tool in Caucasian people, but when used in the South Asian communities it can underestimate health risks. This means that people in this group might face more serious health issues at what is typically considered a healthy BMI, which isn't great. Its well known to be unreliable in people with that have a lot of muscle mass (bodybuilders, Rugby players), but it can also be misleading for people with low levels of fat free mass (the frail and elderly)
BMI was dreamt up by a statistician to be applied in basically the exact scenario of that study. To look at a demographic (age, gender, race, geography) and deduce as a whole. Even better when it's done periodically, as it can plot trends.
Individually, as flawed as BMI can be, if you're comfortably floating in obese (or morbidly obese), then every other metric of health we measure is likely screaming as well.
My GP pretty much disregarded BMI (+2 into "overweight") when we went through my vitals, eating and exercise.
Interesting approach on your Daily Mail disdain..."Offend and Alienate half my viewers". Good idea. I gotta google that business model...
Luckily I don’t need the money so can happily be left with the intelligent half 😂
If half of @Marklewisfitness viewers are Daily Mail readers, then I'm worried about You Tube's algorithm...
@@MarkLewisfitness 🤣🤣🤣
@@MarkLewisfitness Haha I love it when people come complaining to me that they personally don't like the way my video comes across and therefore I'm "throwing viewers away". Yep buddy... if it's viewers like you, good riddance.
😂@@MarkLewisfitness
Some Northern towns have a history of manual labour such as coal mining which may explain why there is a disposition to strong stocky built people. Also there is a link to easy storage of fat in areas where there has been periodic shortages of food.
So historical socioeconomic factors may explain regional differences
Again that wouldnt affect the size of the children so it’s irrelevant
I honestly don't get how kids get fat.
My son eats constantly... CONSTANTLY... he's pretty bloody trim.
Also Jen is a slice.
Mark is pretty decent too... No homo
Loud and clear Mark was distracted by 🤸 and 🩰 …🙄
Yeah, BMI has huge problems but for a population level it's fine. It probably shouldn't be used to diagnose individual people without the doctor also using their eyes.
When i was applying for the uk fire brigade, they were saying they want you to be in the healthy range unless you have a low body fat, so clearly in shape. Then they would use the overweight range as your healthy range.
Which i think is a good way to go about it, just be in this range but we will use our eyes to gauge whether this population level metric works for you as an individual.
BMI is not accurate for people over 5 ft tall
You must know that the BMI was invented by the same people that thought energy for steam engines is the same for people .The calorie .
Hi Jen...Nice top..
I really don't like BMI. But that's purely because I hate seeing people try to use it on an individual basis, when it should only be used for measuring the health of large populations.
When it comes to the individual, BMI is just so horribly off. Not even just for the people who weight lift or carry a lot of muscle. But also for people who carry too much fat, there are many instances I've seen (on DEXA scans) where someone's BMI may claim they are at a "healthy" range, when in actuality they aren't. These are typically skinny fat people, where they could be carrying well over 35% body fat.
So essential you have situations where it's saying that healthy people are unhealthy, and unhealthy people are healthy. Which is a bit of a problem for the individual.
BMI works well on an individual basis in an overwhelming amount of cases. Waistline or BF% might be more accurate, but for it's ease of use BMI is fine. Skinny fats coping thanks to BMI are few and far between compared to tubby lads pretending BMI is inaccurate because of physical outliers they could only ever dream to become.
"Well over" 35% body fat? And still appear in the "healthy" range of BMI?
I don't think so.
I am skinny fat so far as I understand that term... that is, I look fine with clothes on, and pretty obviously flabby with clothes off. Tonnes of flab in places that aren't easily seen in clothes. And I am only JUST within the healthy range of BMI but I am like 21% body fat. I struggle to believe that anyone could be 35% body fat and not be into the overweight, and probably even obese range.
So kids in poorer areas tend to be on the tubbier side? Kids in poorer areas also need free school meals? 🤷♂️🤯
Because eating poor quality food is much more likely to cause overeating of fats and sugar and hence obesity than having something more healthy and nutritious. That's the theory anyway. I'm not an expert but that's what experts say and it makes sense to me.
Childhood obesity is strongly linked to socioeconomic status; its more to do with what they are eating rather than being able to eat (in most cases).
