The BMI is measured the wrong way

Naseem News For the first time in my life, oh horror! I discovered that an additional wheelbarrow had developed around my body, so I decided to give myself a diet to get rid of. The diet was easy: eat less.

I lost 7kg in three weeks and I was gracious.

To celebrate success, I decided to calculate the mass index of my body, and to surprise him found 24.1, one of the highest numbers in the "natural" weight index Known between 18.5 and 24.9.

And through the rest of the tables of numbers, I found that I could lose 20 pounds more and not get out of the normal, but that would make me just bones covered by the skin.

Of course, it made me think: how did the BMI agree scientifically?

Although basic health statistics go back to the 19th century, health experts have currently documented many defects and many times.

At first, the body mass index does not differentiate whether the mass is due to fat or body muscles The man (Michelin) tires and Superman can have the same BMI, regardless of the obvious differences and the muscles in their bodies.

He does not take any other factors to determine the health of the body of age, sex and body type (s).

For example, people who have fat in the rumen area are at greater risk of disease than fatteners in the buttocks and thighs.

My concern is that, nevertheless, BMI is neglected in the basic physical rules. The dilemma of the Belgian mathematical Lambert Adolphe Jacques Quetelet dates back to 1830.

Scale Mathematics. The BMI is defined as the sum of the mass on the square of length.

with the observation that the mass corresponds to the size of the length of the cube.

The result for all this is equal to all values ​​of the mass index directly with the length, which should not necessarily be so. We can blame Gulliver's Travels (17266) of Jonathan Swift for English satirical novelist Jonathan Swift, "Juliver's Travels", in the history of superheroes and superlatives that can not be obtained.

For example, say that a giant is twice as long as twice as long, but it has the same formality and the same structure.

If this giant stood on a flat beach without screens to obstruct his view, so that the observer does not notice by far that it is not me.

And because its mass must match the length of the cube as it is for me, the double longitudinal will weigh eight times my weight.

Thus, the section of her legs will be proportional to the square of the height as I do, so she will only be four times stronger than the Arctic force.

These poor bones will be loaded with extra weight eight times! The giant will collapse under the pressure of his extra weight inevitably.

Similarly, to imagine another similar half-length, the price of my weight will increase, but the bones of the legs and muscles will be twice as strong as necessary.

Nature recognizes this dilemma, so that the bodies of elephants and ants resemble what they are.

The equation of BMI does not share this vision, it can make people heavier, while they are not.

By comparing a person's length of 152 centimeters (5 feet) with a normal BMI of 22, it would be the same as a person with a length of 183 cm (6 feet) with a figure of 26.5 on a BMI, Overweight.

According to body mass indexes, most Australians will have fat, 28% will be considered obese, 35% are overweight, 35% have normal weight and more than 2% will weigh less than normal.

The overweight index will undoubtedly mean that there is a real health problem they are facing, but perhaps an increase in population density since 1830 has affected the result.

Fortunately for Quetlett, there were few people who possessed Koperman's bodies in his day to question his equivalence. Fortunately for Jonathan Swift, he was not there (a muscular engineer) to borrow his satirical work on the giant leap 12 times, indicating that their weight was over 100 tons, and a body mass index more than hundreds.

I do not recommend changing the way the body mass index is calculated, regardless of its flaws.We do not want to take all the records of the last 188 years of BMI (raw data – length and weight – its recording has not been preserved) We can adjust the BMI standard for normal weight, underweight, overweight and fat for height, sex and weight. body shape.

Perhaps then the engineer will be able to lean and relax rather than starve at the edge of skin and bones.
