14 reasons why the BMI is wrong
Your BMI is worthless limit. Sorry not sorry.
It can come like a shock, but simply because you drink kombucha and eatNight oats Do not necessarily mean you are healthy. (Especially if you order fried chicken and waffles for dinner.) The same goes for a weak BMI.
Save a second. You probably scratch your head to thought that having a low BMI (body mass index) does not necessarily mean you are healthy. Especially since your doctor is the one who always mentions your IMC is what qualifies you as obese. What is the agreement here?
Although the BMI formula is a measure of body fat based on a person's weight ratio, it is not always accurate when it comes to painting a precise image of good health. Doctors agree that the BMI is useful as a screening tool for recommending a patient obtaining their blood pressure or cholesterol, but this somewhat medieval measure can often give patients a false hope of hope That they are clear in terms of health when, in fact, they are really not.
So, before taking you, let your three-digit number define your well-being folder, take a look at these reasons why the BMI is not the end of your well-being. And whatever your BMI, make sure you always avoid these40 bad habits leading to a big belly.
The measure has no scientific basis
To calculate IMC, you take your weight in kilograms and divide it through your square height in meters. This will give you a number that then puts you in one of four categories: underweight (<18.5), "normal" (between 18.5 and 25), overweight (between 25 and 30) and obese (> 30 ) Obesity is even subdivided into three categories: Class 1 (BMI between 30 and 35), Class 2 (BMI between 35 and 40) and Class 3 (BMI 40 and more).
So, what is the scientific reasoning behind the formula? Apparently, there is none. Not only the mathematician created the equationnearly 200 years-Adolphe Quetelet-does not have a medical background, but he also created the almost thin air formula; He decided to put the height because this formula gave results that best correspond to the trend of its data. Quetelet simply tried to give the government a quick and easy way to measure the obesity of the general population, so what it created was more a hacking than a formula.
That makes unreasonable hypotheses
As we have already said, the formula and classes of the BMI have been created almost 200 years ago. If we created a way to measure body fat now, we probably would not have designated a "normal" person. Especially since there is no "normal" person. People vary depending on bone structure,genetic, ethnicity and sex. The greatest IMC hypothesis makes everyone leads a pretty sedentary life. (As was the case in Quetelet's time and is the case now.) Although this is true of the "average" person - that's why the BMI continues to be a fairly specific way to look at the trends of the weight population - it does not exactly do not measure the body mass ofindividual. Especially when this person is an antecoptric height, not a sofa potato.
It fails for those who are very short or very big
According to the University of Oxford Professor Nick Trefethen, the term heightted termide divides too much weight by too much when people are short and too small when they are big. Translation: Short people are often told that they are thinner than they are really and big people will be informed that they are bigger than they really are. This can give a false hope of running healthy people and a larger burden on larger people than they need to understand immediatelyHow to lose 10 pounds.
The weight did not correlated precisely with metabolic health
A 2013 study conducted by the University of Pennsylvania doctors and obesity researchers found that the BMI recounted the bad health history for nearly 20% of Americans. The question is that your weight is not always connected to your metabolic health (think: your risk of type 2 diabetes, high blood pressure and high cholesterol).
These same results have been replicated in a large-scale 2016 study published in theInternational Journal of Obesity, which found that only 70% of normal weight BMIs were in the healthy beach of all other metabolic measurements. The problem here? The other 30 percent of people who are not as metabolically are also classified as "normal", which often do not trigger doctors to worry about them. At the same time, 47% of overweight people, 30% of obese people based on BMI and 16% of extremely obese people were alsometabolically healthy. This translates into millions of Americans who are tirelessly by insurers and public health managers to lose weight, but they are really not much more dangerous to die early.
According to BMI, many elite athletes are obese
A specific example that could help you understand how health and metabolic weight are not correlated consist of watching professional football players. Most (if not all) of them have so much muscle mass, it can propel its weight in the obese territory, even if they are healthy and fit. In fact, on the basis of the heights of players and weights (the only two IMC measurement factors), the average football player falls in the obese range, according to a study of theAMERICAN MEDICAL ASSOCIATION JOURNAL.
It does not distinguish fat and muscle
The BMI is supposed to be a measure of body fat, but it does not even take into account the body frame, sex, muscle mass or body fat. Because the IMC measures only height and weight, it does not distinguish the fat and skinny muscle mass. The problem here? Book for the book, the muscle still weighs the same thing as fat, but a man of 180 pounds who is mostly muscular will be better off if he seeksfast weight loss May a man who weighs the same thing but has a higher composition of fat, even if their BMI is the same. This is because muscle tissues burn more calories at rest than fat cells.
This does not bother with the size of the size or distribution of fat
Studies have found that the size of the size is a more precise indicator of obesity than the BMI. Specifically, the height size ratio (WHRT). According to research presented by the British Nutrition Foundation in 2012 "," Keeping your circumference from size at less than half of your size can help increase life expectancy for every person in the world. "According to the study, WHTR was better able to predict high blood pressure, diabetes, heart attacks and traits that BMI. It's because the size of the size is a good measure of the grease distribution around the body. The grease that tends to sit at the waistbig belly -Flower organs like the heart, liver and kidneys more negative than grease around hips and bottom, in terms of cardiometabolic risk.
It gives the illusion that obesity has specific and digital thresholds
Think about it. If you are a 5-foot 5-inch 5-inch woman weighing 149 pounds, you are qualified as "normal". But if you earn a book, your BMI will increase from 24.8 to 25, which then puts you in the overweight category. The weight fluctuates for many reasons, weight of water to increased muscle mass. If you have worked recently, it increases in the "overweight" spectrum could actually mean that you have gained muscle mass. On the other hand, if you live a relatively sedentary lifestyle, you may have been overweight throughout and that you will know in your BMI could be a clock call. Anyway, there is no way to say using the measurement. Take away? There is no specific decimal point that tells you if you are unhealthy or not.
It does not differentiate the types of fat
If you did not already know, there is4 main types of body fat. Some types are "good" and some are "bad". Some are evenreally bad. For example, a 2013 study showed that those who had more belly fat (also called visceral grease), rather than cooking or rear grease, had worse survival rates. This is because belly fat is more harmful than the other fats because they are integrated into your muscles and orgues (instead of sitting just under the skin). Unfortunately, the BMI did not measure the type of fat, which means that many of us are absent from key information.
This does not measure how much body fat
It's not just the type of fat that counts. You may have already known that, but the amount of fat that your body stores also have an influence on your health. And you have guessed IT-BMI does not take that into account. In fact, a 2016 study published in theAnnals of internal medicine found that people with the fastestone fat - any IMC - have the highest death rates. This means even if you are classified as underweight by the BMI, if you have as much body fat as someone overweight, you have the same risk of death. Then yes,lean is one thing.
Bmi is the only definition of obesity
Currently, disease control and prevention centers (CDC) define only adult obesity on the BMI, although we have found that this number can not completely predict your health. The question here is that the government recognizes and legitimate this defective measure, other regulators use it as part of their internal operation. How? 'Or' What? We explain that then:
Businesses and government can exploit the measure
Since the BMI is how we measure overweight or obese, societies, insurers, public health officials and the government rely on this measure to create regulations, which makes sense . Unfortunately, as it is not a precise representation of health, some people can be assigned disproportionately and unfairly of these regulations. For example, certain clauses of the Affordable Care Act and the rules proposed by the Equal Employment Opportunities Commission (EEC) would allow employers to charge "unhealthy" employees up to 30% more than "Healthy" employees for health care costs just because they are just classified as obese measured BMI. Sorry pro football games and bodybuilders.
Lower your BMI do not always correlate with health benefits
Although having a high IMC is often correlated withNegative health problems, Lowering your BMI will not solve all issues related to obesity. According to a twin study of 2016 published inJAMA internal medicineThe twin that had a higher BMI was at a higher risk of diabetes than the twin with a lower IMC, but it was not the case when comparing the risk of heart attack. The results suggest that losing weight may not always reduce the chances of a heart attack. This result suggests that there are many factors behind our health than what our weight and BMI can take into account.
There are better methods for measuring good health
There are many ways to determine body composition and measuring relative health that does not rest on the obsolete body mass index. Try to measure your body fat? Pick up a pair of stirrups or tape measure and use the WHRTR. Or, obtain an analysis of the body composition using a sophisticated scientific tool called bioelectric impedance analyzer (BIA), which sends electrical pulses through your body to determine the amount of your body fat, muscular and water. You can ask a coach of your gym to see if he offers the test. With regard to a measure of health, it is best to consult your doctor about medical problems that you feel that you feel. Otherwise, make sure you do not participate in any of these17 signs that you get older than your duty.
