What is BMI?
Body Mass Index (BMI) is a simple screening measure that uses your height and weight to estimate whether you're in a healthy weight range. It's calculated as weight in kilograms divided by height in metres squared (kg/m²).
BMI categories
| BMI range | Category |
|---|---|
| Below 18.5 | Underweight |
| 18.5 – 24.9 | Normal weight |
| 25.0 – 29.9 | Overweight |
| 30.0 and above | Obese |
BMI is a general screening tool, not a diagnosis - it doesn't account for muscle mass, bone density or body composition. Talk to a healthcare professional for a full assessment.
