The body mass index for men, or the whole truth about the formula
Surely every person on this planet there is at least one friend, a frequenter in the gym, building muscle mass. If we take for men as the only correct result, then our bodybuilder directly falls under the category of people suffering from obesity. It turns out that the world-recognized classification, which determines the state of human health, is not suitable for people who are professionally involved in sports. If so, let's understand how things are going with its application to ordinary people.
Body mass index for men and women: classification
BMI is a relatively simple equation that can be used to find out if a person has excess / lack of subcutaneous fat. Calculations are not just used to determine the degree of obesity, because the results of the formula can also show how great the risk of developing various diseases in the future.All that needs to be done to find out the body mass index of a man or a woman is the weight (in kg) divided by the squared height (in meters). There are seven categories of people depending on the result:
- Less than 17.5. Such a result suggests that a person is on the verge of exhaustion.
- More than 17.5, but less than 19.1. Doctors call this category of people not slim, but skinny.
- From 19.1 to 25.8. This is the very result that you must strive for. Owners of the index within the specified limits clearly have no problems with either excess weight or its lack. All that is necessary for people in this category is to only monitor their diet and keep their skin in good shape.
- More than 25.8, but less than 27.3. This index indicates that the person is overweight, or, as they say in the common people - "in the body."
- Oscillations ranging from 27.3 to 32.3. A clear sign of overweight.
- More than 32.3 and less than 40. Obesity, in which one rejection of your favorite sweets may not affect the process of body deformation that has already begun from within.
- The result of more than 40 says about extreme obesity.
BMI: Is it for everyone?
These are the criteria for determining health in accordance with the formula of BMI.But modern nutritionists agree with the statement that the equation is not for everyone. The fact is that the index is not able to distinguish fat from muscle mass - everything above the norm is an indicator of excess weight.
The purpose and origins of BMI
The problems of the equation assume that the original BMI formula was not intended to measure an individual person. Her goal was to calculate the average weight of the population. At the beginning of the 20th century, medical research began to be conducted, the purpose of which was to establish a link between obesity and early death. So, doctors and insurance companies began to seek out an easy method for determining the percentage of excess subcutaneous fat in humans. Insurance organizations were particularly puzzled by this issue, so they allocated some of their budget to finding an equation that could determine the degree of obesity. Despite all the efforts and the money allocated, they did not achieve the desired result until the book of the researcher Ankel Cayce on obesity indices was published in 1972.As part of testing, Case carried out a series of studies on the male half of the population: he wanted to find out whether the mathematical equations already existing at that time, designed to calculate the fat mass of a person, really work. Fortunately for the scientist, one of the formulas still proved to be usable. This equation turned out to be the Quetelet index, developed by the Belgian Adolf Quetelet in the middle of the 19th century.
Men's Body Mass Index: Destination
Another controversial issue is gender: is the formula applicable to women as well as to men? The catch is that Case and Quetelet conducted their experiments exclusively on the male population of mankind. And to determine the presence of excess weight in the female half, a completely different formula was initially used that takes into account female physiology (as, for example, the amniotic index can be applied only to women). However, to this day, doctors use these calculations in relation to the weak half of the population. Initially, researchers have drawn boundaries between the sexes, but since 1998 they have been canceled for unknown reasons.Now we conclude: the body mass index is not just ideal for men, but was originally created specifically for them, according to the research of Case and Quetelet.
The risk is small
Why so far no one tried to change the system? The reason is simple: the gap between real indicators and those given by the formula is not so great. Therefore, there is no danger here, and doctors are able to determine risk factors using not only other calculations, but also modern equipment.
