What’s your Body Mass Index (BMI)?*

Being underweight could be a sign you're not eating enough or that you may be ill. If you're underweight, contact your general practitioner for further evaluation.

The medical community recommends that you keep your weight within this range.

*The BMI range and classifications described below are based on the recommended Asia-Pacific classification.

People who fall into this category may be at risk of developing obesity. They might also be at risk of developing other health problems, or that their current health problems may worsen. The recommendation is to consult a healthcare provider trained in obesity management.

There are two recommendations for people who fall into the pre-obesity category, which are recommended by European and American clinical guidelines for obesity management in adults.

The recommendation for people with a BMI of between 23 and 24.9 and who do not have weight-related health problems (i.e. high blood pressure or high cholesterol) is to prevent further weight gain through healthy eating and increased physical activity.

For people with a BMI of between 23 and 24.0, and who also have weight-related health problems, the recommendation is to lose weight by combining lifestyle interventions and anti-obesity medications to achieve weight loss and improve health and quality of life.

*The BMI range and classifications described below are based on the recommended Asia-Pacific classification.

People who have BMI equal or over 25 may have obesity, which is defined as an abnormal or excessive accumulation of fat that may harm health. Today a number of health organisations recognise obesity as a chronic, but manageable disease.

World Health Organisation and other health organisations distinguish three classes of obesity:

The BMI ranges are based on the effect excessive body fat has on individual’s health, life expectancy and risk of developing diseases; as BMI increases, so does the risk for some diseases.  

It is recommended that people with a BMI equal or above 25 consult a healthcare provider trained in obesity management for diagnosis, risk assessment and treatment of obesity and weight-related health complications.

The goal of managing and treating obesity is not simply to lose weight, but instead to improve health and lower the risks of other health complications. Losing even a modest amount of weight, such as five percent of body weight or more, and maintaining this weight loss, can improve overall wellbeing, while also reducing the risk of weight-related complications.

There is a range of scientifically proven treatment options for obesity that may be recommended depending on individual needs, health status and the presence or absence of weight-related complications. Treatment may include a combination of the following options**:

Healthy Eating



Increased physical activity



Behavioural therapy



Meal replacements / low energy diets



Anti-obesity medications



Bariatric surgery*

* Bariatric surgery is generally considered for people with a BMI of over 30 who also have weight-related complications. It is also generally considered for people with a BMI of 35 or above.
