About BMI
What is BMI?
Body Mass Index (BMI) is a numerical value calculated from your height and weight. It's a widely used screening tool to categorize whether a person has a healthy body weight for their height.
Is BMI an accurate health measure?
BMI is a useful general indicator but has limitations. It doesn't account for muscle mass, bone density, age, or fat distribution. Athletes with high muscle mass may have a high BMI but be perfectly healthy. Always consult a doctor for medical advice.
What is a healthy BMI range?
For most adults, a BMI between 18.5 and 24.9 is considered healthy. 25–29.9 is overweight, and 30 or above is classified as obese. Under 18.5 is considered underweight.
