Is it possible to independently calculate whether you have extra pounds? What are the parameters of the "ideal" weight? In fact, there is no formula for calculating the optimal weight. Basically, tables of average weights are presented, corresponding to certain ages. Of course, it is impossible to weigh all body fat. We have a different constitution, and, therefore, the layer of adipose tissue has a different thickness. Therefore, doctors use various methods to determine the optimal weight.
The first formula for determining the optimal weight originated in Britain. Its creator is Brock. Initially, this method was used in the selection of soldiers for the Royal Navy. It was invented for practical reasons. The sailor had to be light in order to climb up the ropes. The formula is: "normal weight" = height (in cm) - 100
Another of these methods is called densitometry, when the thickness of the skin folds in different parts of the body is compared with the values in the table. The World Health Organization advises to measure the width of the fold of skin on the back of the shoulder, the point of which is 10-15 cm above the elbow joint. Normally - 1 cm.
But the most popular formula for calculating BMI, in other words, body mass index. It consists in the ratio of a person's weight and height. Known by the name of its creator Quetelet. It is applicable to both women and men. Not only the degree of obesity is determined, but also the risk of diseases of various diseases is identified. How to calculate your personal index? BMI = body weight, kg / height, m squared
The normal index is 24.3 for women and 24.7 for men. To determine whether you need to lose weight or not, you need to compare the resulting index with the table. - BMI less than 19 - your weight is not enough, you urgently need to gain the missing kilograms;
- BMI from 20 to 25 - the norm;
- BMI from 26 to 30 - low excess weight, for prevention purposes, you can choose one of the diets;
- BMI from 31 to 40 - overweight, you need to go on a strict diet;
- BMI above 40 - extremely high weight, you need to see a doctor. But for people involved in sports, pregnant and lactating mothers, the results of calculating BMI can "lie".
