Managing obesity is not as simple as reducing energy intake and increasing energy expenditure. Your body senses weight loss, and actively works to return you to your starting weight.1

There are many causes of obesity.

Your appropriate weight loss options are unique to you.

UNDERSTANDING OBESITY TREATMENT

Obesity management, like the disease itself, is complex and challenging.1 Managing it successfully for the long term is not as simple as reducing energy intake and increasing energy expended.3

Despite your best efforts, your body senses weight loss and actively works to return you to your starting weight.1 Your body does this in two ways. First, the amount of energy your body uses (when resting or exercising) becomes less than would be expected, based on your weight and body composition.1,2,4-6 This change persists for years, even if you regain the weight you have lost.4 Secondly, changes to the hormones which control your hunger and fullness work to push your weight back up.1,4-6

Weight loss has substantial health benefits for people with obesity, such as reducing the risk of developing type 2 diabetes and heart disease and reducing the risk of death from any causes.6,9

CALCULATE YOUR BODY MASS INDEX (BMI)

Body mass index, or BMI, is a calculation based on your height and weight to place you in a weight category: underweight, normal weight, overweight, or obese.1,2,3

BMI can be a useful starting measure to identify your weight classification and risk of comorbidities.

BMI is not relevant if you are under 18 years or pregnant.

BMI is a very general measure that places you in 1 of 6 broad weight categories – underweight, normal weight, overweight, obese.11

YOUR BMI IS: kg/m2

At my BMI, the Australian Obesity Guidelines(9) recommend my target weight loss should be:

 
BMI Classes and Comorbidity Risks10
Classification BMI Risk of Comorbidities
Underweight Less than 18 Increased
Normal weight 18 – 25 Low
Overweight 25-30 Increased
Obese I 30-35 Moderate
Obese II 35-40 Severe
Obese III 40 or greater Very severe

MANAGING OBESITY

Australian guidelines outlines recommendations for percentage weight loss for a range of BMI’s9

  • For BMI less than 30, Australian guidelines does not have a recommendation for target weight loss.9
  • For BMI 30-40, the recommended target weight loss is greater than 10% of your body weight.9
  • For BMI greater than 40, the target weight loss is greater than 15% of your body weight.9

DID YOU KNOW?

Despite your best efforts, your body senses weight loss and
actively works to return you to your starting weight.

  1. The amount of energy your body uses (when resting or exercising) becomes less than would be expected, based on your weight and body composition.1,2,4-6 This change persists for years, even if you regain the weight you have lost.4
  2. Changes to the hormones which control your hunger and fullness work to push your weight back up.1,4-5
  3. Because obesity is a disease with many different causes and it increases your risk of developing other medical conditions, it makes sense to seek help from your doctor.2,7,8
  4. Your doctor can assess a wide range of things that may be influencing your health. Together you can then decide on the best approach for you to lose weight and improve your health.2,11
  5. Weight loss has substantial health benefits for people with obesity, such as reducing the risk of developing type 2 diabetes and heart disease and reducing the risk of death from any cause.6,9
