Body Mass Index (BMI) is a simple measurement used by doctors and health professionals around the world to assess whether a person has a healthy body weight for their height. Here is everything you need to know.
What is BMI? BMI is a number calculated from your height and weight. It is used as a screening tool to identify potential weight-related health issues.
How is BMI Calculated? The formula is: BMI = Weight (kg) ÷ Height (m²)
For example, if you weigh 70kg and are 1.75m tall: BMI = 70 ÷ (1.75 × 1.75) = 70 ÷ 3.0625 = 22.9
BMI Categories:
- Below 18.5 — Underweight
- 18.5 to 24.9 — Healthy Weight
- 25.0 to 29.9 — Overweight
- 30.0 and above — Obese
