A look in the mirror, often this is critical. Am I too fat, too thin or just about right? Do I have to lose weight or gain weight? Questions about your own weight are commonplace for many people. The Body Mass Index (BMI) is a mathematical formula that can be used to calculate a measurement to evaluate your own body weight. What exactly does the BMI say?
If you deal with the topics of weight, weight loss or health you will always meet again on the BMI. Almost all online and print media offer BMI calculators to determine their own BMI value. It is calculated using a mathematical formula composed of your own body weight divided by the size squared. The BMI was developed by the mathematician Adolphe Quetellt in the 19th century. Although the BMI is currently very popular, it is by no means new.
Using tables, it is now possible to determine with the calculated BMI whether one should be in the normal range or in the zone of overweight or underweight with one's own weight, ie decrease or increase. In addition to size and weight, the reference values in the tables also take gender and age into account. Even though the BMI is calculated to be the same for men, women and children, of course the respective interpretation values in the tables are different.
In general, the normal weight is at a BMI of 19 to 24, underweight would therefore be given at a BMI below 19, overweight starts at a BMI over 24 and from a BMI of 30, the weight would be in the range of obesity.
Praise and criticism for the BMI
BMI values are very popular in science and research, they also serve as a guide to doctors. But exactly as such, the BMI should also be considered, it is a guideline, not a universal value, which alone can provide information about normality and health status of the weight.
The main criticism of BMI is that its calculation does not provide any information about the composition of muscles and fatty tissue. For example, if a bodybuilder has a lot of muscle, the BMI would give a value that would indicate overweight according to the table. An active athlete with a high muscle mass would therefore have a high BMI, although no oversized fat stores are available. Likewise, with a high BMI value, targeted conclusions about an increased risk for cardiovascular diseases can not be drawn automatically.
Surely overweight is an increased risk to your own health. However, not only the number of kilos are crucial, but also their respective distribution in the body, whether losing weight would be advisable. Finally, if you are overweight or underweight, always consult a doctor. A physician can provide detailed information about the health status of body and weight by other measuring instruments, as well as recognize related risk factors.
BMI calculator for children
Given the significant increase in overweight children over the past few years, it is very important to pay close attention to a healthy weight ratio of children. The BMI calculator can also be used for children, the table values are based on the standard weight of the respective age. But especially for children should be that the weight can vary even after growth spurt and age. Since children should never be prescribed a diet for weight loss, it is advisable to consult the pediatrician for weight problems.
Conclusion: The BMI can serve as a guideline and control for your own weight and health. Possible consequences (eg diet to lose weight) from the result should always be discussed with a doctor.
