What Does BMI Mean?
Body Mass Index (BMI) is a numerical value derived from a person's weight and height. It is widely used as a simple screening tool to categorise body weight relative to health risk. BMI is calculated by dividing your weight in kilograms by the square of your height in metres.
While BMI is a useful starting point, it does not measure body fat directly and does not account for muscle mass, bone density, age, or sex. Always consult a healthcare professional for a full health assessment.
BMI Categories

- Overweight — BMI 25 – 29.9: Slightly elevated risk of cardiovascular and metabolic conditions.
- Obese — BMI 30 and above: Higher risk of conditions including type 2 diabetes, heart disease, and joint problems.
