Now that summer approaches, networks are flooded with miracle diets and quick fixes to lose weight and look the best type on the beaches. Now, before you start to care (though, bad news, and arrived late this summer), we must know what state is our body and how much weight our surplus. To this end one of the most widely accepted index is the body mass index (BMI). From Blog Women’s how it calculated and how it can be used to calculate our correct weight.
WHAT IS THE ORIGIN OF BODY MASS INDEX?
The body mass index (BMI in short) was developed by the Belgian statistician Adolphe Quetelet in 1835. Originally it was far use that today we give, since the purpose of the author was to determine the importance of anthropomorphism in social attitudes. This is, as was the person physically acted in one way or another.
So, this way of measuring obesity was in the pipeline for many years until in 1972 the author Ancel Keys (the father of Mediterranean diet) put a name to this pattern matemático.Posteriormente, in 1985 two authors of the International Journal of Obesity showed a conscious study, Quetelet index was a reliable indicator of obesity.
NOW, WHAT IS THE BODY MASS INDEX IS CALCULATED AND HOW?
BMI is an index. Determined from height and weight, healthy weight that a person can have. This index is calculated by dividing your weight in kilos, the square of your height in meters:
Let’s see an example: suppose you weigh 85 kilos and measure 1.85 m. In this case and would calculate our BMI: 85 / 1.85 x 1.85 = 24.83.
To interpret the result comes out, we must consult the tables that WHO has determined according to the cutoffs, whether we are at our ideal weight or not.
LIMITATIONS OF BODY MASS INDEX
How we’ve seen so far BMI is an excellent way to learn relatively quickly and reliably if the weight we found is correct or not. However, it also has a number of limitations that we know not to bring misleading:
No considers vital aspects as the complexion of the person (eg, a large person may have less obesity than a small, although it seems the opposite), the body circumferences of waist or hip or fat distribution in the organism.
-The Cutoffs are only valid for people between 20 and 65 years, since childhood-adolescence and adulthood must take more factors into account in determining whether a person is obese or not.
‘It’s not very reliable for people with a lot of muscle mass. Muscles also weighed and applying the formula would reveal a obesity which in that case would not be true.
To find out if you are in the ideal weight, or you can spare a few extra kilos you have to go to BMI classification.
