What Your BMI Tells You
Body Mass Index (BMI) is a simple measure that uses your height and weight to estimate whether you are in a healthy weight range. It is calculated as weight in kilograms divided by height in metres squared.
While BMI is a useful general screening tool, it does not distinguish between muscle and fat. Very muscular individuals may show a high BMI despite being healthy. Use it as a starting point, not a complete picture of health.
Frequently Asked Questions
What is a healthy BMI range?
According to the WHO, a BMI between 18.5 and 24.9 is considered normal or healthy. Below 18.5 is underweight, 25–29.9 is overweight, and 30 or above is obese.
Is BMI accurate for athletes?
Not always. BMI does not account for muscle mass, so athletes and very muscular people may have a high BMI without excess body fat.
