Body Mass Index, or BMI is a simple equation we can use to measure whether our weight is healthy.

BMI is calculated by:

Weight (kg’s) / height (m) ²
E.g someone who is weighs 65 kg’s and is 170 cm’s tall would have a BMI of 22
65 / 1.7² = 22.4913495

BMI categorizes us into different weight ranges:

Underweight – 16 to 18.5
Healthy – 18.5 to 25
Overweight – 25 to 30
Obese – 30 plus

BMI is not perfect and does have some limitations, however it is a good guide in calculating how healthy our body weight is.
