The body mass index (BMI) is a measure that uses your height and weight to work out if your weight is healthy. The BMI calculation divides an adult’s weight in kilograms by their height in metres squared. For example, A BMI of 25 means 25kg/m2.
What is the correct BMI for my age?

- under 18.5 – This is described as underweight.
- between 18.5 and 24.9 – This is described as the ‘healthy range’.

- between 30 and 39.9 – This is described as obesity.
- 40 or over – This is described as severe obesity.
