Calculation of ideal weight

In order to know your weight, you need toto be weighed. But the actual, actual weight is a variable quantity, so for calculations it is necessary to take the average value of several weighings. To determine your weight, it is best to stand on the scales in the mornings, on an empty stomach, in one underwear.

Depending on how the previous weighing day was performed, the weight reading on different days can vary within a few hundred grams or even kilograms.

Ideal weight can be considered, at which the ratio of physical parametersbody and the functioning of the body is optimal. However, like everything ideal, the ideal weight exists only in theory and very few people in practice managed to achieve this weight.

Much more important for a person normal weight, that is, the weight actually observed by the majorityhealthy people. In addition, at the present time, not so much strict numbers as the subjective feelings of a person come to the fore. How comfortable is he in this weight? Do any malaises associated with weight?

Thus, achieving a normal weight andmaintaining yourself in optimal physical form is a much more important and useful task than trying to achieve an ideal weight. However, calculating the ideal weight helps those who want to lose or gain their weight to calculate that "border", above or below which you should not go into your attempts.

Calculation of ideal weight

To calculate the ideal body mass (BMI), you can use the Paul Brock formula, which according to modern nutritionistsis closest to reality. This formula is simple: from growth in centimeters it is necessary to take a certain number - this will be BMI. If the height of a person is 156-165 cm, then you need to take 100, if 166-175 - then 105, with an increase of 176-185 - 110 and with growth over 186 cm should be taken 115.

Besides, when determining BMI, it is necessary to take into account the type of physique of a person and, depending on it, amend the calculation. So, scientists distinguish three types of physique: asthenic (thin-boned), normal and hypersthenic (broad bone). For example, in the asthenic type, 10% should be taken away from the value obtained, while in the hypersthenic type, 10% should be subtracted. With a normal build, no adjustments are necessary.

You can determine your body type by the girth of your wrist. For women, these parameters are as follows:

You can also define your body type using the Pignier index. The formula of the Pignier index (IP) is as follows:

If the obtained value of PI is more than 30, then it is asthenic type, if within 10 to 30 - normal, if less than 10 - hypersthenic.

In addition to Paul Brock's formula for calculating the ideal weight, body mass index formula - BMI. Calculate BMI is not difficult. Growth in meters must be raised to the square and the body weight in kilograms divided by the value obtained.

Body mass index less than 19 indicates a lack ofmass, the index between 19 and 25 is the normal weight. With a BMI of 31 to 35, they talk about moderate obesity, and if BMI exceeds 36, then this is a serious obesity.

Although a BMI between 19 and 25 is considered the norm,"Picking up" to the upper and lower boundaries of this range is equally harmful. It is better to observe the "golden mean". At the same time, if desired, you can lose weight or recover safely for health within this standard.

For example, to find out what is the minimum weightvalid for a certain height, you need to make a return to the BMI calculation of the level of the minimum, that is, for the number 19. BMI should be multiplied by height in meters squared. The resulting value u is the desired weight.

Similar formulas for calculating the ideal weight giveonly an average representation and can have a large enough error. For a more accurate determination of weight, it is necessary to take into account a lot of additional factors, such as the amount of physical exertion, intensity of activity, diet, etc.
