What is BMI?
Body Mass Index (BMI) is a numerical value calculated from your weight and height. It provides a simple indicator of whether you may be underweight, normal weight, overweight, or obese.
The formula is: BMI = weight(kg) / height(m)²
BMI Categories
- Underweight: BMI less than 18.5
- Normal weight: BMI 18.5 to 24.9
- Overweight: BMI 25 to 29.9
- Obesity: BMI 30 or greater
Understanding Your Results
- BMI Prime: Your BMI divided by 25. A value less than 1 indicates you are not overweight.
- Healthy Weight Range: The weight range that would put your BMI between 18.5 and 25 at your current height.
Note: BMI doesn’t directly measure body fat and doesn’t account for muscle mass, bone density, or overall body composition.
