Does a Normal BMI Range Equal Good Health? Most Americans are undertrained. According to the most recent data, adult obesity rates now exceed 35 percent in four states, 30 percent in 25 states. and are above 20 percent in all states. Normal Weight Ranges: Body Mass Index (BMI) Body mass index, or BMI, is a way to help you figure out if you are at a healthy weight for your height.

BMI is a number based on your weight and height. In general, the higher the number, the more body fat a person has. BMI is often used as a screening tool to decide if your weight might be putting you at risk for health problems such as heart.

For example, here are the weight ranges, the corresponding BMI ranges, and the weight status categories for a person who is 5′ 9″. Height Weight Range BMI Weight Status; 5′ 9″ 124 lbs or less: Below 18.5: Underweight: 125 lbs to 168 lbs: 18.5 to 24.9: Normal or Healthy Weight: 169 lbs to 202 lbs: 25.0 to 29.9: Overweight: 203 lbs or more: 30 or higher: Obese. However, at a population level, we do know that on average a person with a high BMI has a greater chance of suffering from many non-communicable diseases, including diabetes and heart disease. Healthy weight is defined as a body mass index (BMI) equal to or greater than 19 and less than 25 among all people aged 20 or over. Generally, obesity is defined as a body mass index (BMI) equal to or greater than 30, which approximates 30 pounds of excess weight.

Excess weight also places people at risk of developing serious health problems. 14 rows · It’s one way to see if you’re at a healthy weight. Underweight: Your BMI is less than 18.5. BMI values less than 18.5 kg/m² are considered underweight. BMI values from 18.5 kg/m² to 24.9 kg/m² are healthy.

Overweight is defined as a body mass index of 25.0 to less than 30.0 kg/m². People with BMIs in this range have an increased risk of type 2. For people who are considered obese (BMI greater than or equal to 30) or those who are overweight (BMI of 25 to 29.9) and have two or more risk factors, it is recommended that you lose weight.

Even a small weight loss (between 5 and 10 percent of your current weight) will help lower your risk of developing diseases associated with obesity. BMI 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 Height (inches) Body Weight (pounds). What’s a normal BMI? A normal BMI is between18.5 and 25; a person with a BMI between 25 and 30 is considered overweight; and a person with a BMI over 30 is considered obese.

A person is considered underweight if the BMI is less than 18.5. As with most measures of health, BMI is.

A BMI above the healthy range is less healthy for most people, but it may be fine if you have lots of muscle and little fat.

However, the same report states that a BMI above or below the healthy range may actually correspond to a healthy status and, conversely, having a BMI which falls inside the healthy range may not necessarily mean being healthy, because the body composition may be abnormal even in the presence of a physiological BMI.

Although there is debate about the ideal BMI, it is generally thought that a BMI of 20to 25kg/m represents healthy weight, a BMI of 25 to 27 kg/m is associated with somewhat elevated risk, a BMI above 27 kg/m represents clearly increased risk, and a BMI above 30 kg/m carries greatly increased risk.

  • That was really short. However true. I’ve always been rather stout so the BMI index irritates me but seeing it as a bench mark is still helpful.

  • But they should get different healthcare​ insurance bracket. Just like smoking and drinking. Then there actually is an incentive to get healthy.

  • That’s right. I am 5ft 6 and weigh 156. My body fat is 14%. I wear a size 6 dress and pants. Athlete level. BMI is not always accurate. I eat healthy and stay active. I am muscular and lean and fit.

  • I knew which foods I need to eat to lose weight, but I didn’t know how much. Diet plan I got from NextLevelDiet contains portion sizes for every meal. Fantastic!

  • I guess it’s mainly co-founder.
    People with high BMI usually eats tons of trash food. People with low BMI usually are malnourished I mean, there are obviously, but it’s about vitamins, minerals, essential amino-acids, essential fatty acids intake, not calories intake per se.
    At least, so it seems to be.

  • Body fat percentage is a far better measure of health. It’s tough to find an accurate method of measurement, though. Water tanks and air pods (better at measuring body density) take up a lot of space. Body calipers aren’t very accurate, and scales use an electrical current that can be affected by hydration level.

  • I bet the people responsible for those opposing “studies” are proponents of the “fat acceptance” movement lol!

    I mean yeah, let’s treat everyone nicely and stuff, but don’t bullshit about it…

  • Using a person’s body mass index to calculate weather they make be overweight or not is very flawed. These calculations do not account for muscle mass like he stated and gives a person a skewed idea of this health. A person could be of average high but have a large amount of muscle and be view as overweight just because they physically weight more but are in perfect health. However, it is not surprising that has the BMI moved away from normal, in either direction, the mortality rate increased. Having an extremely low BMI could indicate that they are not receiving the proper nutrients that they need to survive and same with a high BMI. Malnutrition could be happening in both categories, so these outcomes are not surprising.

  • I’m pretty underweight (BMI 15-16) but I think I have an infinite metabolism or something because I can’t seem to gain weight no matter what I do. Im a huge ice cream fan and I eat WAY more than I should but the massive sugar and fat intake never seems to have an effect on me. Is this bad? Is this normal?

  • BMI does NOT measure fat, only ratio of weight and height. A body builder with high muscle mass and low body fat percentage will have a higher BMI. Can’t take this video seriously when you get the definition wrong.

  • For the people that this video could genuinely help (like me) it can be incredibly difficult to hear this topic discussed without bringing to mind a lot of emotional baggage. I want to learn and I want to be convinced. But it doesn’t help that you literally scoff and use a patronizing tone of voice several times. It also doesn’t help that this video is significantly less thorough than any other video you’ve done. You usually cite a lot more references and bring up a lot more opposing opinions and disprove them. You usually run for far longer than 3 minutes and 43 seconds. Your video on the wage gap is one of my very favorite videos on the Internet. I would love to see you approach this topic in that way.

  • 2100 calories on day with low carbs? Lol maybe he’s shredding. It would be hard to keep a big frame like that on those clean calories

  • If you ask me, it’s really hard to gain muscle and lose weight at the same time, but website called NextLevelDiet is great for that. They also calculate your BMI and calorie intake for FREE and provide you with diet meal plan and training plan.

  • i’ve heard my grandma say to me so many times that i should eat more (BMI currently at 18.3). today she finally said something better “oh, give that dough/batter to her. she can eat it because she weighs so little.” go grandma!^^

  • BMI is shit. It’s about being healthy, according to your metabolism and to your genetics. You CAN have a low or high BMI and be healthier than those in the “healthy BMI range”, because you have higher muscle mass, lower bone density or do more sport/eat better than those “regular looking office workers”.
    It’s all about not going into extremes in ANY DIRECTION. BMI shows just a ratio between your weight and height but that is no indicator for anything. Fat acceptance is OK as long as you’re active, your body doesn’t get in your way, and you’re happy. Thin acceptance, ditto. And if like me you have a fairly low but acceptable BMI you should still check your eating habits, your daily life schedule and possibly drink more water and exercise regularly.

  • it would be interesting to analyse the lower BMI, to take into account the reasons people fall into this category. I’m sure there would be a totally different outcome for those who were underweight due to anorexia, for example, as opposed to athletes who were adhering to a nutrient dense diet.

  • Do any of these studies add in additional social determinants of health to disaggregate the impact of poverty (limited access to nutritious foods, ability to exercise on a regular basis, etc) on the metric of BMI?

  • Im 11 and my bmi is 30.7 im only 45 or 44 kg and im not even that fat, well kinda but not until i have flaps. I dont have flaps and i play soccer quite often.

  • Dr. Carroll, I think you’ve oversimplified the research here. People with higher BMI had higher mortality, but it doesn’t follow that the BMI caused the mortality. In repeated studies, having a high BMI means you are at higher risk for metabolic diseases like Type 2 diabetes and NAFLD, and people with metabolic disease are at much higher risk of mortality. However, in people with high BMI but no metabolic disease, the risk of mortality is roughly equal or even lower than normal weight people.

    This is not to advocate for high BMI. Please aim for a healthy, normal weight; but from a public health perspective, it makes more sense to focus on preventing metabolic disease instead of BMI. One way to reduce your risk of metabolic syndromes is to maintain a healthy weight and exercise, eat a healthy diet, keep stress levels low; but even if you struggle with weight loss or maintenance, those other behaviors can keep you healthy and at reduced risk.

    I’ll cite some recent papers on this topic in a separate comment.

  • 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.

  • The bmi is so dumb

    I was told I’m obese cuz I’m 5’6, 14, and 155 lbs

    Normally that is very heavy

    But the doctor knows I’m a competition dancer, so im dancing 4-6 hours a day for 6 days. So a that weight is muscles

  • There’s the Metabolically Health Obese (MHO) phenotype that you really should have included. A few recent papers on the topic.

    Nutrients. 2016 Jun; 8(6): 320.
    “Does Metabolically Healthy Obesity Exist?”

    Nutrition. 2016 Jan;32(1):14-20.

    “Metabolic health is a more important determinant for diabetes development than simple obesity: a 4-year retrospective longitudinal study.”

  • at 20-25 mortality was minimal. but can you tell us where, more exactly, was the lowest mortality within this goup? At the low end(20 bmi) or at the middle(22-23 bmi)?

  • I personally have a decently high bmi but of you saw me you’d say wow he actually looks really healthy. I play football and have to be bigger but idk us weird.

  • I love this video and its points, but I cringe whenever I hear someone start to talk about BMI. For whatever reason, I weigh about 9 kg (20lbs) more than I look like I weigh. I’m 72 kg (160lbs) currently, but I probably have the body fat percentage of someone who weighs 63 (140). It ends up throwing off my BMI so I seem overweight when you can clearly see I’m just average (in weight, not in fabulousness ��)

    I think we need a new system that’s more accurate

  • Two major criticisms with this. One, you don’t mention cause and effect. Is being overweight causing you to die? Or is something you could die from causing you to be overweight? Two, there is no mention of if weight loss will reduce risk of mortality. When doctors see research like this, it reaffirms their belief that telling an overweight patient to lose weight is good practice, but is it really? Does losing weight in and of itself cure people of hypertension, Type II diabetes, high cholesterol, or any other health concern that is generally associated with high body fat ratio? Where’s the research?

    In other words, is it clinically indicated to tell an overweight person who eats nutritionally well, engages in regular cardio exercise, and is otherwise the picture of perfect health that they need to lose weight? Or is it just fat shaming?

  • In BMI (Body Mass Index) 18.49 and below is considered as Underweight. From 18.50 to 24.99 is considered as Ideal Weight or Correct Weight. From 25.00 to 29.99 it is considered as Overweight. From 30.00 and above is considered as Obese.

  • Then there’s the paradoxical findings on cardiovascular disease and obesity. Metabolically healthy obese people have risk factors that are elevated, but no increase in mortality in a systematic review of 584,799 individuals.

    PLoS One. 2013; 8(9): e74564.
    “Metabolic Health Is More Closely Associated with Coronary Artery Calcification than Obesity”

    J Epidemiol Community Health. 2016 Apr 28.
    “The long-term prognosis of cardiovascular disease and all-cause mortality for metabolically healthy obesity: a systematic review and meta-analysis”

    The meta-analysis confirms a positive association between a metabolically healthy obese phenotype and the risk of CV events. However, higher risk for all-cause mortality is not evident in metabolically healthy obese individuals.

  • Do you have better ways to measure what is a healthy weight for an individual? From my understanding BMI is a decent way to measure weight in large groups but it’s not good for individuals because of variations in builds or muscle mass. According to BMI I am obese (34.75) but my doctor has told me not to aim for a “healthy” BMI because of my bone structure and musculature but they won’t give me a number to aim for either.

  • I lift weights. At 200lbs my bmi is 25 but my bodyfat is like 15% which is perfectly healthy. My BMI can go over 25 and I still have a below average bodyfat. it’s hardly unhealthy for me to be 26 BMI with bodyfat of around 17%?? I doubt this study is robust enough to factor in or apply to gym rats!!

  • I love how everyone here immediately jumps to “being fat is bad” when the % increase of mortality of low BMI is actually higher.

    As with everything, moderation is key.

  • The issue of fat shaming is never the very idea that being fat is bad for your health, it is the fact that weight being a health problem is used as a rationale for bigotry and ridicule of fat people.
    It’s not the actual reason they are shamed and ridiculed, people do this because they are assholes and find fat people ugly or funny. They use the health problems that comes with being fat as an excuse for why this inexcusable behavior is “okay”.

    Being fat is one of very few health issues that people feel is okay to comment about to absolute strangers in public. People tell fat folks to stop eating in public places all the time. Perfect strangers commenting on what you are eating, or how much of it. “Haven’t you had enough?”.
    In fact, people even mock fat folks who are making an effort to lose weight. If you are fat and walk or jog outside, it can often come with glances, giggles and jokes. As a fat guy I learned to avoid streets with crowds when I run outside, because I just don’t want to be mocked for my efforts at losing weight. People with more body image issues than me were no doubt discouraged from their efforts entirely by this kind of mockery.
    Fat people posting pictures of themselves on social networks are routinely mocked, ridiculed, shamed… as well as counselled by what sounds like well-meaning but somewhat patronizing folks on what they should do to fix their problem. In the context of being surrounded by abuse, those well-meaning comments take a very different tone, and are far from supportive.

    This is why people who have this problem can sometimes be oversensitive to the discussion of weight as a health problem by itself, because of its relation to bigotry they may actually experience on a day to day basis. The well-meaning advice and the insults blend together into an ugly morass of patronizing trash. It doesn’t make the rejection of reasonable information like this video make rational sense, but we are not entirely rational beings, and sometimes it’s good to have a little empathy to realize why some people might lash out where it seems unwarranted.

  • Quick question: I thought that the BMI as a metric only applied to sedentary adults. Is that the case for these studies? Do active people, like Olympic athletes, with a high or low BMI have higher mortality rate than sedentary adults in the normal BMI range?

  • The studies also suggest what exactly we call/think of, as healthy or unhealthy is somewhat incorrect. That a BMI of 27.5 (overweight) is objectively more healthy then being a BMI of 18.5 which we call “healthy”. And the underweight, even a small amount, is linked with a large health risk then class 1 obesity. This is to say that someone who is 5’6″ and 110lb is less healthy than someone who is 5’6″ and 190, but I would bet if you asked people “who is healthier?”, 9 of 10 would pick the thin one. Though for the US, on a national level, only 10% of adults are under 20 BMI and 25% are about 33 BMI.
    Also, while BMI is reasonable on a mass scale, for any one person it can cause all kinds of issues as it does not take into account muscle mass. A strong/muscular man will have a fat free mass index (you BMI after you subtract you body fat weight) of 19 or 20, in the most natural extreme cases 25, where as a weak/skinny man will have a fat free mass index of 15 or so. So, as strong man with a reasonable healthy, 20% bodyfat, will have a BMI of 25.5 and he is overweight. Where as the weak/skinny man with an unhealthy, 30% bodyfat, will have a BMI of just 21.6 and he is “healthy”. Though this is limited to just 5 BMI points and is NOT a reasonable excuses for people to be obese.

  • Did many studies in this meta-analysis track participants’ eating and exercise habits? Obviously, poor nutrition and a sedentary lifestyle would mess with anyone’s health, and often lead to obesity. But many overweight and obese people eat healthy and work out. So, is this meta-analysis conflating correlation with causation? I’m seriously asking. I’m not an expert on this stuff.

  • Well, I think people need to bear in mind that the measured outcome is mortality. It does not measure the association with potentially significant life quality reducing diseases such as osteoporosis, diabetes etc. If you are under or overweight, you may not die but you may suffer from painful, cranky, weak joints and bones that may render you bed ridden for the rest of your life. Many viewers I think are in their 20s? You should certainly not become complacent.

  • I became so energized to use the diet weight. I didn`t change my very own eating routine and did not improve my workout level. More than a period of a month, I dropped around 6 lbs. The process has let me consumed less and getting full is quicker. Find a right weight is not easy, you can research on Google. Guide’s name is below.

  • The problem with studying obesity is that it’s strongly correlated with poverty, sedentary lifestyle, poor diet and many other negative contributors to health. Many of these factors cause obesity or are caused by obesity in some, but not all, cases (i.e. obesity increases the risk of sprained ankles, which can make sedentary behavior more likely) further making this difficult to study.

    Unfortunately, if you tried to exclude people with all of these problems, you’d end up with a population of football players and body builders.

  • 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.

  • Aren’t there numerous studies showing that those who are overweight and exercise are healthier than those in normal weight but don’t exercise on all causes of mortality. I.e. BMI is an indicator of exercise not of health.

  • My take on fatshame/acceptance. As someone who has lost a lot of wieght, but still needs to lose a lot more to be healthy(down to around 250(around 32%bf) from around 300)

    First it is obvious that being fat is unhealthy. But I don’t think It’s obvious that being fat is a choice. Anyone who has lost a lot of weight and tried to keep it off knows that it’s super hard. Hunger is distracting. It kills focus and makes everything difficult. I was able to get down to 230 by counting cals, but i can’t afford to be hungry rn because I’m studying for my PHD Quals, so between not counting and starting to lift weights(235lbs squat for 3×5 after 3 months), my weight is up about 20 lbs over 5 months. So first you need to decide how much of a choice it is. If it is not very “choice” then you need to decide if you should shame people for things outside of their control, which I think you shouldn’t. Personally, I feel like it’s a grey area choice. For some people staying light is much harder, but everyone can do it.

    Second, if it is a choice you need to decide if being unhealthy is something you should shame people for. and I don’t think that that is obvious one way or the other, because I don’t think that its a moral issue. There are tons of avoidable risky behaviors that we don’t shame people for, like driving, sex, and some drugs.

    All that to say, I don’t think “fat shaming” is great. It doesn’t get much done and is logically dubious. But “fat acceptance” is also pretty idiotic. If you are fat, you are unhealthy and should try as much as you can to get un fat. But I also don’t think that people should feel horrible for being fat, because it’s not a moral question. Wanting to stay fat is stupid not evil; it is illogical to choose being fat over being healthy. As a result, very few people actively want to stay fat. That is my take

  • Before anyone gets upset at this video remember he is strictly talking about the health costs of being underweight or overweight. This video isnt about how people should be treated, it has nothing to do with looks, its not saying you are a worse/better person due to your BMI.

    Its important that we can discuss these things without the social issue baggage thats normally attached.

  • What is the best way to lost crazy amounts of weight? I read a lot of superb opinions on the internet about how Custokebon Secrets can assist you lost tons of fat. Has any one tested out this popular lose weight diet plan?

  • BMI is a completely debunked way of determining someone’s health. Please stop referring to it in discussion. It’s like Phrenology, it inaccurate, it’s pseudoscience, it shouldn’t be entertained by scientists and medical professionals!

    How is it that the middleweight boxer that trains cardio almost every day and has <5% body fat can be classified as "overweight"?! Rugby League players running around on the field for 80 mins with muscle on their muscle are classified as "obese".

    BMI is complete bullshit. Skinfold caliper tests actually determine percentage body fat (the shit that actually determines how fat you are) use those instead, along with blood tests to measure your ACTUAL health!

  • Could you do a video about weight loss and health? Recently many people are claiming that losing weight does not increase longevity and some outright say that losing weight can decrease your lifespan.

  • Sir, muje weight gain krni hai to kya diet lu.. or ek puchna tha muje piles ka problem hai to ho sakta hai gain muscle meri??? Please rply me

  • REDO YOUR CIRCUMCISION VIDEO. All children, girls AND boys, have the right to genital integrity regardless of the research.
    Unless male genital mutilation is curing cancer, it should be banned.

  • 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.
