How to calculate body mass index

Having calculated the body mass index, you can determine which weight is perfect for you. You will be able to find out if it was too extinguished with diets and exercise, it's not time to eat less sweet and spend more time in the gym. In order to calculate body mass index, you will need scales and roulette or centimeter tape to measure the performance of your weight and growth.

First you need to weigh. Keep in mind that the time of the day is affected by the time of day, the intensity of physical exertion, stress, the amount of consumable food and beverages, even the time of year. It is best to weigh in the morning, an empty stomach, while possible without clothes or in the underwear. It is advisable to use electronic scales - they are more accurate. Also remember that the mass of the body of a woman during critical days is more than 1-2 kg, in which case it is better to wait for a couple of days.

The next step is to measure growth. If you do not know what your height you have, find a roulette or centimeter tape, in general, something that can be measured. Stand near the door jamb, walls or any other smooth vertical surface, clinging to her heels, buttocks, shoulders and heads. Stand smoothly, lift chin. Do not forget to remove shoes and hats, make your hair on the top of the top smooth. Put the pencil on your head and make a mark. For convenience, you can ask friends or relatives to help you measure the growth.

Next, begin to calculate the body weight index using the formula: I \u003d M / H², where M is a body weight in kilograms, H is a growth in meters, units of measuring kg / m².

To understand what weight is suitable for you, compare the result with the recommended WHO interpretation of the body mass index indicators:

16 and less - there is a shortage of body weight;
16 - 18.5 - body weight is insufficient;
18.5 - 25 - normal weight;
25 - 30 - excess;
30 - 35 - obesity I degree;
35 - 40 - obesity of II degree;

But keep in mind that this method does not give absolutely accurate data, only an indicative estimate that needs to be checked with the help of other techniques, if the result does not satisfy you. Do not sit on a rigid diet, without making sure the correctness of the calculations.
