What Is BMI and Why It Matters?
BMI (Body Mass Index) is a standardized way to estimate body fat based on height and weight. It helps determine whether you’re underweight, healthy, overweight, or obese.
This calculator uses the World Health Organization’s BMI classification:
– Underweight: BMI < 18.5
– Normal: BMI 18.5 – 24.9
– Overweight: BMI 25 – 29.9
– Obese: BMI 30+
Maintaining a healthy BMI is linked to lower risk of diabetes, heart disease, and other chronic conditions.
