ratio tablesused by professionals. But keep in mind , weight indicators vary slightly depending on gender , age and physiological characteristics of a person. There are different formulas for determining the optimal ratio of weight and height. But all of them are very, very conditional , since they do not take into account many factors: age , gender and physiological characteristics of a person.

Therefore, excess fat must be assessed not only by the conditional ratios presented in this table , but also by appearance , skin thickness and a number of other factors. With the same height and weight, one person may look full , the other - completely normal.

The objective parameter of an ideal body is the percentage of fat and musculoskeletal tissue. For men, the norm is 9 - 15% fat of the total body weight , and for women - from 12 to 20%.

**1. Quetelet Index**

Knowing the Body Mass Index ( BMI), one can judge obesity or underweight. The index is calculated for adult men and women from 20 to 65 years old. The results may be false for pregnant and lactating women , athletes , the elderly and adolescents ( under 18). Among the many different methods for calculating ideal weight , the most popular method is height-weight index , body mass index - Quetelet index.

FORMULA: BODY WEIGHT IN KG DIVIDE BY HEIGHT IN SQUARE METERS B / (P * P)

FOR EXAMPLE: HEIGHT 170 CM , WEIGHT 65 KG. MEAN 65 : ( 1.7 * 1.7) = 22.5

The Quetelet index shows well the amount of fat in the body , but does not indicate how fat is distributed , in other words , it does not give a visual-aesthetic picture.

But you can check your body for ideality by another formula. The distribution of fat throughout the body is determined by the ratio: waist ( at the level of the navel) divided by the volume of the buttocks.

The norm for men: 0.85

For women: 0.65 - 0.85.

**2. Does age affect the**

**height-weight** **?** The answer is unequivocal. Yes , of course it does. It has been proven that the weight of a man and a woman should gradually increase with age - this is a normal physiological process. Kilograms , which some people consider "superfluous", in fact, they may not be. You can use the formula to determine the optimal weight depending on age. **3. Broca's Formula: Revealing Height-Age-Weight Relationships**

One of the most popular methods for calculating ideal weight is Broca's formula. It takes into account the ratio of height , weight , body type and age of a person.

BROCK'S FORMULA FOR PEOPLE UNDER 40 YEARS IS EQUAL TO "GROWTH ( IN CM) MINUS 110", AFTER 40 YEARS - "GROWTH ( IN CM) MINUS 100".

At the same time, people with an asthenic ( thin-boned) body type should subtract 10% from the result, and people with a hypersthenic ( broad-boned) body type should add 10% to the result.

**4.How to determine your body type?**

The physique is usually divided into THREE types: normosthenic , hypersthenic and asthenic. In order to find out what your body type is , it is enough to measure the circumference of the thinnest place on the wrist with a centimeter. The resulting circumference in centimeters will be the necessary indicator ( Soloviev's index).

**5. Nagler's formula for the ratio of height and weight**

There is Nagler's formula , which allows you to calculate the ideal ratio of weight and height. 152.4 cm of height should account for 45 kilograms of weight. For every inch ( i.e. 2.45 cm) over 152.4 cm there should be another 900 grams , Plus another 10% of the resulting weight.

**6. John McCallum's girth ratio formula**

One of the best formulas , created by expert methodologist John McCallum. The McCallum formula is based on measuring the girth of the wrist.

- 6.5 wrist circumference equals chest circumference.
- 85% of the chest circumference is equal to the circumference of the hips.
- To get the waist circumference , you need to take 70% of the chest circumference.
- 53% of the chest circumference is equal to the thigh circumference.
- For the neck circumference, you need to take 37% of the chest circumference.
- The circumference of the biceps is about 36% of the circumference of the chest.
- For the lower leg, the girth is slightly less than 34%.
- The circumference of the forearm should be equal to 29% of the circumference of the chest.

But not all physical data will exactly match these ratios , the numbers have an average , average value.

**7. A few more options for the ratio of height and weight**

The physique is considered ideal if the waist circumference is 25 cm less than the hip circumference , and the hip circumference is approximately equal to the chest circumference

. The waist circumference should be equal to "height in centimeters - 100". That is, a woman with a height of 172 cm will be proportionately folded if the waist circumference is 72 cm , is about 97 cm , that is, if she wears clothing size 48.

If the hip circumference is less than the chest circumference , and the waist circumference is less than the hip circumference by 20 cm , then such a figure is called an "apple". If the chest circumference is less than the hip circumference , and the waist circumference is 30 cm or more less than the hip circumference, this is a pear-shaped figure.

For women and girls of average height - from 165 to 175 cm - this observation turned out to be fair.

Their waist circumference in centimeters is approximately equal to their weight in kilograms. One kilogram of weight loss gives a decrease in the waist by one centimeter. As you can see , there are many ways to calculate the optimal ratio of your height and body weight , depending on a variety of factors. But no matter how you do the calculations , the main thing is that your weight is COMFORTABLE for yourself. So that you can easily and freely feel in your own body , love yourself and enjoy life to the fullest! – without getting depressed from the fact that during the calculations you ( and suddenly!) found out an “overabundance” or “lack” of kilograms.
