What is the body mass index (BMI)

in our lives is a concept introduced a Belgian statistician and sociologist Adolphe Quetelet. The body mass index - a value in which a person's weight is related to his height. With the help of it you can calculate whether the weight for your height is normal. But the method is not acceptable for children, the elderly, people who play sports professionally, pregnant women. For them has its own method of calculations.

How to calculate body mass index

BMI is calculated as follows: you need to weight in kilograms divided by height in inches squared. For example, a man weighing 80 kg with an increase of 180 cm would have the following BMI: 80/1, 80² = 22, 2. This result can be checked with the following standards.

Category first. BMI below 18, 5

You run the risk of having health problems such as lack of nutrients, the absence of the menstrual cycle (amenorrhea in women), brittle bones and other diseases. And the lower the BMI, the more you risk more.

the second category. A BMI of 18, 5 and 25

The weight is normal. You do not have to change your weight anymore. You are in the category of people who have minimal risk of disease due to weight problems. For young people under 25 years old is considered to be the best indicator of BMI from 22 to 23. If you are at the upper limit and you think that your weight is already excessive, the measure waist. The norm is the growth of minus 100 women, and up to 94 cm in circumference in men. All that is higher - the deviation from the norm. Should begin to pay attention to nutrition. Category Three. A BMI of 25, 0 and 30, 0

Category fifth and sixth obesity grade II and III

It is complex in nature, often linked to lifestyle, eating habits, or heredity. The risk of complications of obesity is very high. It is necessary to see a specialist.
