How to calculate your BMI:

To calculate your BMI, you will need an accurate – preferably digital – weighing scale, a metric tape measure and a calculator.

  • First, weigh yourself in kilograms.
  • Next measure your height in meters as accurately as possible.
  • Then divide your weight (kg) by your height (m) squared as follows:

                                  WEIGHT (KG)_______________          =      BMI (kg/m2)

HEIGHT x HEIGHT (M)

If your BMI is:

  • <18.5 – you are underweight
  • 5 – 24.9 – you are in the normal weight range
  • 25-29.9 – you are overweight
  • >30 – you are obese Class I
  • >35 – you are obese Class II
  • >40 – Class III morbidly obese.

The higher the BMI, the greater the risk of developing certain conditions, including diabetes, high cholesterol, heart disease, particular cancers, and the obvious wear and tear on the joints due to the weight. Alternatively, the lower the BMI, the greater the risk of malnutrition and osteoporosis.
