Calculate your BMI, understand your health category, and get WHO-based health advice instantly.
Body Mass Index (BMI) is a simple medical measure that estimates body fat based on height and weight. It helps determine whether a person is underweight, normal, overweight, or obese.
According to the World Health Organization (WHO):
• Underweight: below 18.5
• Normal: 18.5–24.9
• Overweight: 25–29.9
• Obese: 30 or higher
The BMI formula is the same, but women naturally have slightly more body fat. BMI is a general indicator and doesn’t differentiate between fat and muscle.
Yes. For very muscular people or athletes, BMI can overestimate body fat because it doesn’t consider muscle mass or bone density.
Maintain a balanced diet, exercise regularly, drink enough water, and get sufficient sleep. Always consult a healthcare professional before making major lifestyle changes.
