WHAT IS BODY MASS INDEX (BMI)?

The body mass index (BMI) is a great way to establish whether or not you’re in a healthy weight range and is based on height and weight. The BMI index is a useful measurement for most people over 18 years, however, there are some limitations to be aware of as it may be influenced by age, gender and ethnicity.

EXCEPTION TO THE RULE

Muscles: The BMI calculator cannot distinguish between fat and muscle. Those with higher than average muscle mass (body builders, athletes etc.) will end up with a misleadingly high BMI value.

Certain populations: BMI and the above-mentioned classification are also unsuitable for certain populations and individuals, including Aboriginal people, Pacific Islanders, children, pregnant women and the elderly.

For all these reasons, you should treat it as a rough guide to be used in conjunction with other body-weight calculator.

WAIST CIRCUMFERENCE

Measuring your waist circumference is a great predictor of your health. No matter what your height or build are, an increased waistline can be a sign that your health is more at risk.

The BMI calculation is a guideline only as it does not take into consideration fat to muscle ration, which affects BMI results. Therefore, it may not be appropriate for athletes or those of muscular build.
