Häufig gestellte Fragen

What is Body Mass Index (BMI) and how is it calculated?

Body Mass Index (BMI) is an internationally recognized screening metric used by the WHO and CDC to classify human weight categories. In Metric, the formula is: BMI = Weight (kg) / [Height (m)]². In US Imperial, the formula is: BMI = [Weight (lbs) × 703] / [Height (inches)]².

Does BMI distinguish between muscle mass and body fat?

No. BMI is an epidemiological screening tool based on total body weight rather than body composition. Highly muscular athletes, bodybuilders, and pregnant individuals may record an "overweight" or "obese" BMI despite having low body fat and excellent cardiovascular fitness.

What is a healthy BMI range for adults?

According to the World Health Organization (WHO), a healthy BMI for adult men and women is between 18.5 and 24.9 kg/m². Values below 18.5 suggest underweight, while 25.0 to 29.9 indicates overweight, and 30.0 or higher indicates obesity.

What is the Ponderal Index (PI)?

The Ponderal Index (or Corpulence Index) is calculated as Weight (kg) / [Height (m)]³. Unlike BMI, which scales height by a square factor (2D), the Ponderal Index scales height cubically (3D), providing a more proportional evaluation for very tall or very short individuals.
