Ideal weight is a concept that undergoes significant changes over time and fashion trends. However, today more and more people are inclined to determine the ideal weight in terms of medical indicators, rather than the standards of fashion magazines.

## Ideal weight calculation methods

At different times, there were various methods that were used by people to calculate the ideal weight. Some of them were very simple, like Brock's formula. She assumed that in order to calculate his ideal weight, a person under the age of 40 needs to subtract the figure 110 from his height in centimeters, and after 40 - the figure 100. The value thus obtained was supposedly ideal for a particular person, however, it quickly became clear to the adherents of this formula that it gives too average values that may not be applicable to a particular person.

Other formulas, on the contrary, were distinguished by the use of a large variety of coefficients, which gave them a very authoritative look. This was, for example, Cooper's formula. She suggested calculating the ideal weight differently for men and women. For men, the formula was as follows: ideal weight = (height in centimeters * 4, 0: 2, 54 - 128) * 0, 453. For women, the same indicator was calculated as follows: ideal weight = (height in centimeters * 3.5: 2, 54 - 108) * 0, 453. However, despite its cumbersomeness, this formula also did not take into account many individual characteristics, for example, body type.

## Body mass index

As a result, today, one of the most adequate methods for calculating the ideal weight according to the method of Cuttle, who proposed calculating the so-called body mass index (BMI) for each person. Despite its relative simplicity, this technique has gained wide acceptance both among ordinary people who want to control their weight and among the medical community.

This is largely due to the fact that the calculation of BMI involves the definition of not a specific figure, which is the ideal body weight for all people with certain characteristics, and the range that is the norm for these people. So, it is considered normal to consider the body mass index, which ranges from 18.5 to 24.9.

In order to calculate your BMI, you need to divide the weight, expressed in kilograms, by the square of your height, expressed in centimeters. So, for example, the body mass index for a woman weighing 60 kilograms, who has a height of 170 centimeters, will be calculated as follows: BMI = 60 / (1, 7 * 1, 7) = 20, 76. Thus, comparing the obtained value with the given boundaries, you can see that this weight value is normal for this woman. Moreover, if BMI is less than 18.5, this indicates a weight deficit, and a value exceeding 24.9 is an excess.
