About BMI

Body Mass Index (BMI) is a measure of body fat based on height and weight that applies to adult men and women. It is used as a screening tool to identify possible weight problems for adults.

While BMI is a useful indicator, it has limitations. It does not directly measure body fat and may not be accurate for athletes, elderly individuals, or those with high muscle mass.

Note for South African users: The World Health Organization (WHO) BMI standards are used universally, including in South Africa. However, consult with a healthcare provider for personalized advice.
