Weighing the Facts of Obesity

“People who have a normal BMI may carry a good amount of their weight in their stomach which increases their risk for chronic diseases,” says Spano. For men, waist-circumference levels should be below 40 inches, and for women it should be below 35 inches. Even if your waist is within the normal range, you should monitor it for changes over time. According to the BMI scale, if you fall between 18.5 and 24.9 you’re considered to be a normal, healthy weight. (This means the person in our example above is just over the line of being at an ideal weight.) If you clock in below 18.5, you are considered underweight.

But if you’re from India, your risk of diabetes starts going up with a BMI of about 21 or 22.” In contrast, many African-Americans may have a high BMI, but. One of the biggest problems is that it cannot distinguish between fat and muscle. Thus more athletic and active people can easily fall into the overweight categories. It is a vague number – It has been found that the index can underestimate the number of obese people.

And since it is not directly connected with the fat percentage it is hard to judge where exactly the line should be. If your BMI is under 18.5, you are considered underweight. If your BMI is between 18.5 and 24.9, you are considered within the normal range. If your BMI is between 25 and 29.9, you are overweight. If your BMI is anywhere from 30 to 39.9, you are obese.

About a quarter of people with normal BMI measures had an unhealthy cardiometabolic profile. Actually, this should come as no surprise. BMI, as a single measure, would not be expected to identify cardiovascular health or illness; the same is true for cholesterol, blood sugar, or blood pressure as a single measure. Why should I not use it, I hear you ask? Well first we shall have a look at what it is used for and how it is calculated.

What Does BMI Tell You. The BMI is used to assess weight relative to height, the calculation used for this is to divide your body weight in kg by your height in meters squared. That’s it, it only uses 2 figures. According to the BMI weight status categories, anyone with a BMI between 25 and 29.9 would be classified as overweight and anyone with a BMI over 30 would be classified as obese.

However, athletes may have a high BMI because of increased muscularity rather than increased body fatness. Because the BMI is a single number between 1 and 100 (like a percentage) that comes from a mathematical formula, it carries an air of. For adults aged 20 and older, a BMI less than 18.5 is low, and puts you in the danger zone. A number between 18.5 and 24.9 is a normal BMI; a BMI between 25 to 29.9 is overweight and a BMI of 30 and higher is obese.

However, exceptions do exist for all these ranges.

BMI is just a screening tool, though.

There are other, better ways to tell if someone has an unhealthy amount of fat, but they are harder to measure, which is why people use the BMI to begin with.

But a normal BMI doesn’t necessarily mean health when chronic disease is the norm.

In other words, 91% of what accounts for a health outcome has nothing to do with BMI.

Some experts criticize BMI because it makes no distinction between fat and muscle, but here I’ll follow Moore et al., who used BMI and the World Health Organization definitions of BMI <25 as normal, BMI between 25 and 30 as overweight, and BMI >30 as obese.

Interestingly, in subjects with a BMI in the normal to overweight range, where most of the disagreement in results have been generated, BMI has its worst diagnostic performance.

In addition, Flegal found that people who are “overweight” (with a BMI of 25 to 29.9) live longer, on average, than those at a “normal” weight (a BMI between 18.5 and 24.9).27 These inferential problems get even worse when the discussion turns to the question of diseases.

However, it should always be borne in mind by researchers that the BMI range is a continual scale and attempts to convert it into a set of categorical judgments are likely to impose an additional set of inaccuracies in the assessment of body fat levels.

Linking obesity to cardiometabolic risk, body fat distribution, and waist circumference is more important than measuring percentage body fat or BMI alone.

  • Interesting video full of information… Every ailment depends on the lifestyle of a person and everyone should follow a healthy lifestyle along with correct,medication. You can prefer planet Ayurveda for treatment in natural ways and manufacturing products with no side effects. you can prefer thinner you pack for better results and no side effects.

  • A health care professional who places emphasis exclusively on BMI is someone who, in my humble opinion, is shortsighted. The BMI does not take into account muscle to fat ratio nor does it respect the fact that many people may actually be healthier and look and feel better at a BMI above 25.

  • My fat is half the weight of my muscle and I’m kinda holo boned which means my bones are lighter than they supposed to be and I’m 160 pounds:/

  • the first part just sounds as a complex excuse for ppl to not take responsibility for their situation. (reminded me the vibe of… the more assured ppl sound the more ignorant or delusional they often are ) m… slightly fat children became the future fat dudes m… yes that’s all because name-calling and not related at all to genetics right nutrition adjustments exercise sleep etc..
    actually name-calling often crates enuff pain for ppl to take action it just that most common spread advice for obesity is the wrong one(ake most the fast dies or starvation regimes or overtraining) so let’s just focus on not name-calling instead of figuring and spreading the right solutions…
    whole foods, no industrial oils, no sugars, moderate exercise, no wheat and grains, carbs mostly veggies fruits are just as treat, stable circadian cycle and relaxation with meditation for mental stability aka stress and cortisol removal. couldn’t keep watching past her oghhh

  • I am so glad I am not to blame for being over weight, i diet and exercise everyday
    And can’t lose weight thank you for this cutting edge research and real science so I
    Don’t have to take personal responsibly for my own actions.

  • If it has NOTHING to do with what we eat, then why is obesity mainly affecting wealthy countries. How many obese children are there in the poorest regions of the world? I mean really poor. Strange poor Africans, obviously in Africa, according to you have the same genes yet are not obese.

  • BMI is completely stupid iv seen Women where actually slim to slim thick like Jessica rabbit but are considered morbidly because of BMI.

  • boring over eaducated western thinking. How about talking about lack of education about fasting. I am from Afghanistan and we were raised to eat 5 days a week and fast for 2

  • And,yes, your Dr does judge you….after what I considered a very successful appointment with a new kidney specialist to explain my gfr of 58, we discussed my continued effort to loose weight….I had already lost 15 lbs…..189 down to 174 over 3 months……Planning on loosing another 20…..she told me my kidney function was normal for my age and encouraged me to continue with my plan…..there was no clear cut emphasis or extreme emphasis on her part..She ended the appointment with, “ Don’t worry,you will never be on dialysis.”…
    I was shocked to read her report of our meeting in “ my chart” access on line a week later.
    It read that my “ chronic kidney disease” was probably directly related to “ my obesity”…
    Had she said that to my face I would have learned to things…1. She mislead me by telling me my kidney function is normal for my age (72)…..2. She mislead me by really thinking I am obese and that was at the root of my problem…..I was wearing an xl in my clothing and went down to a medium/ large.
    My waist is where my fat is rendering me “ obese” in medical jargon.

  • BMI can mislead in more than 20% of people. If you are very muscular, very tall or very short, your BMI isn’t a good representation of your health. Much better is the Waist/Height ratio. Measure your waist at the belly-button and divide this number by your height (you can use inches or cm, but be consistent). If this number is greater than 0.5 then you’ve got work to do…

  • Wow, a bully at age 5…maybe not meaning to be but just the honesty of kids. I’m glad as adults it worked out. I was told in junior high that I was gross from being too skinny and it was equally as hurtful. If I ran into that girl again, though it wouldn’t end as nicely.

  • I kinda envy fat people they can eat and gain pounds and then covert that to muscle. Me having the same metabolism of a small rodent and can’t put on weight.

  • One of the common diseases people undergoing in present days is obesity. Many of the people try to control it by doing diet and exercises but in many cases it will not help. Homeopathy is best way to overcome it as the homeopathy medicines do not rise to any side effects in future. For best homeopathy clinic regarding obesity, Homeocare International is best with good success rate. For details, visit onlinehomeocare.com

  • hey all, The easiest results that I have ever found is using Tims diabetes fix (i found it on google). Without a doubt the most incredible system that I have ever tried. Get off the injections in weeks.

  • Lol!!! Michael Jordan NEVER weighed 242 in his career. He was in the normal range throughout his entire career (200-216 lbs). Terrible example!!

  • Yeah, but even too much muscle can be too much weight, and decrease your lifespan….the lighter the better, even with muscle, it is not a guarantee of good health…..too much muscle, not good…waist for men should be, generally, 32″

  • Doctors need to retrain their brains because Keto diet answers all these questions and gives real solutions. Obesity Cure: Stop Eating Carbohydrates,  Inter. Fasting, Exercise,  and Sleep there’s your real lecture.

  • Congratulations Harvard! You just went full SJW. “Bias” causes t2 diabetes and high blood pressure?! It’s not the fact that you’re fat as fuck? The reason that 2 out of 3 of people in the US are fat must be because eating disorders caused by “bias” and if they wouldn’t feel ashamed then people wouldn’t be fat? Get real!

    Also, can somebody please explain the difference between correlation and causation to this woman.

  • It’s not the BMI, it’s the milk and eggs that you eat every day that is going to stop your heart one day, it’s very high in cholesterol and these guys are programed to mislead people about the stupid BMI crap, I am 1.96m tall, 36yo 160kg weight and I can still satisfy my wife in bed, I don’t suffer from hypertension or diabetes and I’m very active, my heart is fine because I don’t eat those to poisonous foods, thank me later. ��

  • 6’1, 185 pounds, 28 inch waist. Bench press 285, squat 405, play basketball 3 days a week, and hike, camp and kayak frequently. I was marked down as overweight for a 25.5 BMI on my health screen and lost points towards my premium decrease.

  • Calorie input versus calorie output. Stop stuffing your mouth full of high calorie, low nutrition, crap food… when you feel bored or emotional. Get off your ass and walk, ride bike, swim do something.

    When I travel to USA I am stunned at the size of people, how much they eat, how often they eat and how very little they move.

    Sad this behavior has trickled down to their kids.

  • Nowadays so many people are suffering from heavy cholesterol. Due daily activities main reason for this problem and junk food. Homeopathic treatment is the safest treatment bearing less pain. Constitutional treatment is the natural treatment for Obesity.

  • A health care professional who places emphasis exclusively on BMI is someone who, in my humble opinion, is shortsighted. The BMI does not take into account muscle to fat ratio nor does it respect the fact that many people may actually be healthier and look and feel better at a BMI above 25.

  • I’m 12, 5’8 and weigh 186..I dont have any belly fat rly.. No muscles rly either..but im still overweight by 28 pounds.. I look skinny and healthy and im so confused of how im over weight because I srsly dont even have a big stomach..

  • So many of these are inaccurate. I’m losing my faith in people called “doctors.” The real summary is that your BMI means nothing unless your percent body fat matches the exact number of the underlying assumptions in the calculation that is over 100 years old and was never meant to apply to individuals, only to populations. The ratio of waist to hips has application to how you carry your weight and can affect things like your potential to acquire diabetes or similar disorder but not hear disease. What’s important is to have a percent body fat, which is based on your body density (including bone, muscle and fat density) relative to your age and sex. Older people naturally carry more fat, and that’s healthy.

  • Being overweight can lead to a number of health issues in senior men, such as several outlined in this article: https://athomecarecompany.com/top-health-risks-senior-men/

  • triglyceride has nothing to do with cholesterol. It’s 3 linear molecules of fatty acids attached to one glycerine. cholesterol is a ring-shaped steroid based molecule. cholesterol is only made by animals (including humans) while triglyceride is also found/made by plants.

  • Yeah, but even too much muscle can be too much weight, and decrease your lifespan….the lighter the better, even with muscle, it is not a guarantee of good health…..too much muscle, not good…waist for men should be, generally, 32″

  • BMI = BULLSHIT, Just eat clean, exercise and be active and as long as you can carry on with your weight with no health problems so why give a fuck about BMI.

  • BMI can mislead in more than 20% of people. If you are very muscular, very tall or very short, your BMI isn’t a good representation of your health. Much better is the Waist/Height ratio.

  • I play basketball, do parkour, gymnastics and even bboying. The Doctor told me I am overweight and need to see a dietitan. Looking forward to see her, taking off my shirt and showing her my pecs and big biceps. I will also ask her which new sport I need to take up

  • at 15:10 she tells a straightforward lie. Googling “white teens” brought up way the same amount or MORE mug shots when I tried it today compared to googling “black teens”.

    Its unfortunate that googling white or black teens brings up mug shots in the first results…but it isn’t evidence of race inequality or racism, unless you count teenager as a race.

    Frankly, it is disappointing when someone makes claims like this about racial inequality because all it does, imo, is further a narrative understanding that isn’t based on facts…even worse, why does it seem like someone would like this example of racial inequality to exist? It would be awful if it did, but her claim about the google results is inaccurate.

  • Thank you for the information.

    The incidence of type 2 diabetes, hitherto considered a disease of middle and old age, has been steadily increasing among children and adolescents. Data from developed countries shows that this increase parallels a similar rise in the prevalence of childhood and adolescent obesity. While type 2 diabetes in children and adolescents is as yet not a major public health problem in India, recent reports revealing increasing levels of obesity among youngsters especially in our metropolitan cities, gives cause for concern.

  • There is so much fuss about BMI. I was reading an article http://www.wellmanclinic.org/2017/12/14/body-fat-matters-rethinking-the-bmi which is also saying the same. Jeff is pointing out the right facts about BMI. Thanks for sharing this.

  • Momentum=mass X velocity. If you don’t have enough mass, you will not be able to perform as well in certain sports. That’s just a fact. If I were at my “ideal” BMI, then I wouldn’t be able to throw an opponent in judo, for example. Pure muscle and bone like Michael Phelps is very rare. BMI makes everyone feel like a failure.

  • If you look at Martin Berkhans formula for the Natty Limit, BMI charts actually works out consistently (just shifted higher into the overweight range). The maximum amount of body mass you can gain with a bodyfat of 10% would end up with a BMI around 25-26(Just slightly overweight), or with 20% bodyfat a BMI around 28-29 (Just below obese). So for the guy to have it measured as straight up obese, he either have a high bodyfat percentage, or on roids, or both.

  • Sleep… k, let’s continue to ignore the massive amounts of sugar and the demonizing of fats for another 50 years, see where that leads us. Lets ignore that cholesterol was never a cause of anything, and that the lipid hypothesis our friend Ancel Keys concocted in the 50’s was never proven, and yet we pushed grain and sugar on the masses based on nothing…
    Stop looking for genes and start looking at the giant behemoth the processed food industry has become. Oh wait, they pay you research grants. Nvm.
