CALCULATE YOUR BMI

Body mass index or BMI is used to determine whether you are in a healthy weight range for your height. Learn more about your body mass index.

ARE YOU AT A HEALTHY WEIGHT?

The Body Mass Index (BMI) is a way to determine whether your weight is a healthy range. It is considered a more useful measurement than weight alone. The BMI algorithm looks at your body weight in relation to your height and it is therefore deemed a more useful measurement than weight alone.

The BMI calculator will categorize you as being underweight, normal, overweight or obese. In Asia, a body mass index of over 23 is regarded as overweight and a body mass index of 27.5 and above is considered obese*.

WHAT IS BODY MASS INDEX (BMI)?

The body mass index (BMI) is a great way to establish whether you’re in a healthy weight range and is based on height and weight. The BMI 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.

WHAT THE RESULTS MEAN?

Based on your BMI calculation, you can determine your classification based on the chart below.

BODY MASS INDEX (KG/M2)	CLASSIFICATION
Below 18.50	Underweight (Risk of nutritional deficiency diseases)
18.50 to 22.9	Healthy weight (Low Risk)
23 to 27.4	Overweight (Moderate Risk)
27.5 and above	Obese (High Risk)

EXCEPTIONS TO THE RULE

Muscles: BMI 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 indicators.

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 ratio, which affects BMI results. Therefore, it may not be appropriate for athletes or those of muscular build.
