Calculation of body weight, different techniques

Supporters of diets and fitness are trying to achieve a beautiful figure and ideal weight, but this concept is very vague and incomprehensible. What is the ideal weight? People of the same height and weight can look absolutely different, beauty simply can not be put in numbers.

However, some tentative formulas still exist. One of the most popular methods is the calculation of body mass index, shortly called BMI. The calculation method is very simple: its mass in kilograms should be divided by the value of growth, expressed in meters and squared. The result should be interpreted as follows: less than 20 - mass deficit, 20-23 - normal, 24-29 - excess weight. The number above 29 indicates obesity. But this primitive calculation of body weight, despite its popularity, is considered inaccurate, the calculation does not take into account the type of bone structure.

The following calculation of body weight is considered more accurate. First, you need to measure the volume of the wrist, the result of 14 to 18 centimeters is an indicator of normosthenic physique, and less or more, respectively, asthenic and hypersthenic. Next, the weight in grams is divided by its height in centimeters and the result is estimated according to the table.

Indicators are also very conventional, so even this more complicated technique will not help to calculate the exact body mass index. The calculation used in the following method can also help in the difficult matter of determining its ideal weight.

This calculation is called the Lorentz formula, according to it the ideal weight is calculated as follows: from the growth expressed in centimeters, 100 is subtracted, and the value obtained from the difference in growth in centimeters and 150 divided in half. With an increase of 169 centimeters, the expression will be as follows: (169-100) - (169-150) / 2.

Also recently, one of the British mathematicians, who believes that the traditional calculation of body weight gives a somewhat incorrect result, proposed a new formula. According to this technique, its mass in kilograms should be multiplied by 1.3 and divided by the growth in meters, multiplied by 2.5. The result can be interpreted according to the same indicators as the traditional BMI.

However, any of these methods misses information about the amount of fat in the body, that is, a bodybuilder can show a result above the norm, although the percentage of fat in his body is very small. Therefore, any universal calculation of body weight is suitable only as an inaccurate reference point.

Determine the composition of the body and the percentage of fat is also quite easy, but this requires a special tool, and even better - a professional dietician or fitness instructor. With the help of this tool, wrinkles are measured on different parts, which can be formed, and the average result is displayed.

Another study that helps determine the composition of the body is impedance measurement. Using a special device through some areas of the body to pass a weak current and measure the resistance. The procedure is completely painless, but it helps with a high accuracy to determine the amount of fat and water in the body. Such a study can be done at a fitness center or clinic.

In fact, universal formulas, with which you can calculate the body weight, suitable for different people, no. When determining your ideal weight you need to focus on your own health, reflection in the mirror and advice of professionals.
