Tip 1: How to determine the optimal weight

Is it possible to calculate by yourself whether you have extra pounds? What are the parameters of the "ideal" weight? In fact, the formulas for calculating the optimal weight no. In general, tables of averaged weights corresponding to various ages are presented. Of course, we can not weigh all the fat deposits. We have a different constitution, and, therefore, the layer of adipose tissue has a different thickness. Therefore, to determine the optimal weight doctors use different methods.

Instructions

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 in the Royal Navy. It was invented from practical motives. The sailor should have been easy to climb up the ropes. The formula is as follows: "normal mass" = height (in cm) - 100

Another such method is calleddensitometry, when the thickness of the skin folds in different parts of the trunk is compared with the values of the table. The World Health Organization advises to measure the width of the skin fold on the back of the shoulder, the point of which is 10-15 cm above the elbow joint. In norm - 1 cm.

But the most popular formula for calculating BMI, in other words, the body mass index. Is in the ratio weight and human growth. Known by the name of its creator Quetelet. It is applicable to both women and men. It determines not only the degree of obesity, but also identifies the risk of diseases with various diseases. How to calculate your personal index? BMI = body weight, kg / height, m squared

The normal index is 24.3 for women and 24.7for men. To determine if you need to lose weight or not, you need to compare the resulting index with the table. - BMI is less than 19 - your weight is insufficient, you urgently need to gain the missing kilograms; - BMI from 20 to 25 is the norm; - BMI from 26 to 30 - low excess weight , for prevention, you can choose one of the diets - BMI from 31 to 40 - overweight, you must sit on a rigid diet - BMI above 40 - extremely high weight, you need to see a doctor. But for people involved in sports, pregnant and lactating moms the results of the calculation of BMI can "lie."

Tip 2: Which Quetelet index corresponds to the normal weight

People who are not indifferent to their health,be sure to follow the weight. There are many techniques that help determine the ideal ratio of height and weight. However, few of the amateurs know what the Quetelet index or body mass index is.

The works of Adolphe Quetelet in mathematics, astronomy and sociologists are known throughout the world. But for women, he, first of all, the creator of a unique formula, helping to keep himself in shape.

What it is?

Everyone who is going to lose weight, it is necessaryto inquire what is the Quetelet index or the body mass index. Without such information, one can so get carried away by a diet that this will lead to exhaustion and health problems. Body mass index (BMI) is used by many nutritionists to determine the normal weight. Also, using a special formula, you can identify insufficient or excess body weight. To determine if weight corresponds to height, you need to divide the body mass by the height in meters, squared. For example, 60 kg: (1.6m X 1.6m) = BMI 23.44. This is recognized as a norm that is not harmful to health.

What indicator should I adhere to?

The Quetelet index, corresponding to the normal weight,will help to part with many complexes, and stop striving for a ghostly ideal and excessive leanness. So, in people whose BMI is equal to 18.5-25 units, everything is in order. They just have to lead an active lifestyle and eat healthy foods to keep fit. If the BMI fluctuates between 16 and 18.5, you need to think about weight gain. These indicators are not critical, but still worth a visit to a nutritionist. People who have the Quetelet Index dropped below 16 units most likely need medical help. A similar pattern occurs in dystrophics and girls suffering from anorexia. At BMI 25-30 it is already talking about excess body weight. This situation requires a diet and active sports. Otherwise, BMI can grow to 30-35 units, and this is the first degree of obesity. Usually people whose body mass index is 35-40 know that they have weight problems. This picture signals a second degree of obesity. A BMI, exceeding 40 units - on the third degree.

Additional Information

Since the Quetelet index corresponding to the normalweight, is a conditional indicator, it does not take into account the physique. For example, in professional athletes BMI is very high due to the large amount of muscle mass. Therefore, it is necessary to take into account the parameters of the body, and also to measure the percentage of fat in the body. For the last action at home, you will need special scales. By setting the growth rate, sex and age on such scales, you can find out how much fat is in the body, and how much muscle and water.
