BMI (Body Mass Index) is an indicator of high body fatness. BMI can be used to screen for weight categories that may lead to health problems but it is not diagnostic of the body fatness or health of an individual. It is calculated as follows:

BMI = Weight in KG / Height in Meters²

The standard weight status categories associated with BMI ranges for adults are shown in the following table.

BMI	Weight Status
Below 18.5	Underweight
18.5 24.9	Normal or Healthy Weight
25.0 29.9	Overweight
30.0 and Above	Obese
