The development was therefore primarily for economic rather than health policy reasons.

The height and weight are set in relation to each other, but the fat percentage, the muscle mass and bone density are not taken into account. This particularly affects strength athletes who have a low body fat percentage with a higher body weight. Therefore, the BMI is only of limited use for assessment, as it is for people with a higher bone density or a larger bone diameter. What is important overall is how comfortable you feel in your body and with your weight, whether you live healthily and consciously and eat accordingly.

How suitable is the BMI for classifying health risks? 

The BMI provides a rough guide to weight-related health risks. However, the BMI is not reliable enough as a sole measure, as it does not take individual circumstances into account. Just because your BMI is too high or too low, you are not automatically at risk of health problems. Nor can the BMI guarantee that people of normal weight are not exposed to health risks. Even athletes with a very high muscle percentage and therefore a correspondingly higher weight, the BMI does not provide a reliable value, as they are heavier due to the heavier muscles. muscle mass are quickly classified as overweight. Similarly, people of normal weight with very little muscle or a light bone structure could quickly be classified as underweight, even if they are not from a medical point of view.

For these reasons, the BMI should not be overestimated, but should only be used as a guide. If you are unsure about your BMI, it is best to talk to a doctor.
