1. To learn the BMI, you need to determine the exact growth and weight. Calculation formula simple. For determination of body mass index divide the exact weight in kilograms into growth in meters squared. That is, for example, if your height of 1.64 m, and the weight of 59 kg, then formula looks as follows: BMI = 59 / (1.64 x 1.64). Having solved simple mathematical task, we receive result. BMI is equal to 21.85.
2. Of course, knowledge of the BMI does not give you full information to understand whether there is threat to your health, whether you have obesity. For this purpose it is necessary to remember that if the index is equal 20-25, then you have nothing to worry, weight is normal. At BMI at 25-30 there is already increased risk for health. High it will be at result 30-35. And at 35 and more it is necessary to think of weight loss as it is already dangerous seriously. It is not obligatory to remember all these numbers, the nobility the most comfortable limit of BMI for organism - 20-25 is enough - and to try not to go beyond its framework.
3. Remember that this formula suits practically all, but there are exceptions. Weight-lifters, pregnant women and the feeding women, elderly people and children should not take these numbers for reference point. To define whether your child has obesity, calculate BMI by the same formula. But you remember that normal BMI at children is less, than at adults — from 15 to 18.5. The number depends on age. The child is more senior, the number is more.
4. If you have learned the BMI and on all indicators of obesity at you is not observed, and all the same it seems to you that the figure is far from ideal, measure waist measurement. At women the risk for health exists at waist measurement over 88 cm. For men this figure is equal to 102 cm. The small risk is if volumes more than 80 and 94 at women and men respectively. If you are dissatisfied with the results and measurements, begin to lose excess weight. But do it intelligently. You can consult with the expert, aggressive diets can result in even more deplorable results.
