Your Body Mass Index (BMI) is the single best way to decide whether you are the right weight, the fittest weight, the most beautiful weight, the best weight for YOU.
Your BODY MASS INDEX (BMI) measures your body fat and it is worked out using your height, your weight, whether you are a boy or a girl, and on how old you are.
The only information required to calculate your Body Mass Index is
1. Your height in metres so for example if you are 124 centimetres tall you are 1.24 metres tall.
2. Your weight on kilograms for example 6.12 kilograms
3. Your date of birth
4. Whether you are a boy or a girl
