How Medical Weight Loss Programs Work in Australia
A medical weight loss program is a structured plan run by registered health practitioners. It starts with an assessment of your health, builds a plan around a healthy diet and physical activity, adds further treatment only if a practitioner decides it suits you, and includes regular follow-up.
This is general information, not medical advice. It does not describe the right plan for any one person, and outcomes vary between individuals.
What Is a Medical Weight Loss Program?
Weight management services in Australia come in several forms: accredited practising dietitians, GPs, commercial weight loss programs, meal replacement programs and kilojoule-controlled meal services (Better Health Channel). A medical program is the one led by doctors or nurse practitioners, in a clinic or by telehealth.
What sets it apart is the clinical side. A registered practitioner looks at your whole health picture before anything else, can order tests, can refer you to other health professionals, and decides whether treatment beyond diet and physical activity is appropriate. Australian guidance treats obesity management as long-term care by a team of health professionals, not a one-off visit (Australian Obesity Management Algorithm, 2024).
The Steps of a Medical Weight Loss Program
Australia's clinical guidelines for managing overweight and obesity set out the 5As approach for health professionals: ask and assess, advise, assist and arrange (NHMRC, 2013). The five steps below are based on that framework. The details differ between services, and a step can take more than one appointment.
Outcomes vary between individuals.
Step 1: Your health history
Many services start with a health questionnaire or intake form. It asks about your weight history, health conditions, current medicines, allergies, lifestyle, and what you have already tried. Answer it fully: the practitioner relies on it to decide what else to ask and check.
Step 2: A consultation with a registered practitioner
A doctor or nurse practitioner then talks with you, in person or by video or phone. The conversation covers your history, your goals and what matters to you. For what the practitioner asks and how to prepare, see what happens at a weight loss consultation. For how online consultations, treatment and follow-up fit together, see how online weight loss consultations and treatment work.
Step 3: The assessment
The practitioner looks at the measurements and health factors covered in the next section. They may ask for recent blood tests, results from your usual GP, or an in-person check before deciding anything.
Step 4: A plan agreed with you
The plan is built around eating and activity changes that suit you, with support to change habits. Depending on your assessment, it may include referral to a dietitian, exercise physiologist or psychologist, or further treatment the practitioner considers suitable. You agree to the plan; it is not handed to you.
Step 5: Follow-up and review
Regular follow-up is part of the program from the start. At each review the practitioner checks progress and any side effects, adjusts the plan, and refers you on where needed. The guidelines describe this step as regular follow-up visits, referral as required, and support for weight management over the long term.
What a Practitioner Checks
The Australian Obesity Management Algorithm bases the treatment path on body measurements and on whether weight-related health conditions are present, and how severe they are.
BMI is less accurate for elite athletes, for people of Asian or Polynesian background, and for some other groups. A waist of 94 cm or more for males, or 80 cm or more for females who are not pregnant, carries a higher risk of problems such as type 2 diabetes and heart disease (healthdirect).
Victorian Government advice says to speak with your GP before starting any weight loss program, especially if you already take medicines from your doctor or have a condition such as diabetes, a heart, kidney, liver or thyroid condition, gallstones, depression, or a history of disordered eating. For more on that route, see whether your GP can help with weight loss treatment.
In practice, the checks usually cover:
| What is checked | Why it matters |
|---|---|
| BMI (weight for height) | A starting measure, less accurate for some people |
| Waist measurement | Linked to health risk |
| Blood pressure, glucose, cholesterol | Screens for related health conditions |
| Health conditions and medicines | Some change which options are suitable |
| Pregnancy or breastfeeding | Changes what is suitable |
| Mental health and eating history | Shapes the right kind of support |
| What you have tried before | Guides the next step |
After the assessment, the practitioner may recommend further tests, a face-to-face review, or a different path, such as referral to your GP, a dietitian or a psychologist. That is part of careful care, not a refusal. For more detail, see who qualifies for weight loss treatment.
What Treatment Options a Program Can Include
Treatment for obesity can include a low-calorie diet, more physical activity, weight loss medication and bariatric surgery (healthdirect). A team that can include a dietitian, exercise physiologist, lifestyle coach or psychologist can help you make a plan that suits you, and cognitive behavioural therapy can help you recognise when and why you eat.
Changes to diet and physical activity are part of every approach. The Australian Obesity Management Algorithm calls supervised lifestyle changes an essential part of every weight loss strategy. Where weight loss medication is used, it is used while you reduce your kilojoule intake and increase your physical activity, not instead of them. It has side effects and is not suitable for everyone, and only a registered practitioner can decide whether it is appropriate for you after an individual assessment.
For how these options compare, see whether diet and exercise alone are enough and how weight loss medication compares with bariatric surgery.
Costs: What to Ask Before You Start
Costs vary between providers, so compare the full picture, not a headline figure. The Better Health Channel says a good weight management service offers details on all fees and costs of additional items, and gives clear information on its refund policy. Before you sign up, ask for these in writing:
the fee for the first consultation, and whether follow-up appointments cost extra
whether any treatment, tests or delivery are charged separately
how often you pay, and whether there is a minimum term
how to cancel, and what the refund policy covers
For what public and private cover can contribute, see what Medicare and private health cover can pay for.
How to Choose a Medical Weight Loss Program
Victorian Government health advice lists what a good weight management service does, and what to avoid. The table sums it up.
| A good service | Be wary of a service that |
|---|---|
| Aims to improve your overall health | Cuts out whole food groups |
| Suits your individual needs | Replaces food with powders or supplements |
| Tracks body fat and waist, not only weight | Pushes short-term changes |
| Includes physical activity most days | Uses saunas, body wraps or diuretics |
| Advises no less than 5,000 kJ (1,200 cal) a day | Focuses on losing weight in a short time |
| Welcomes input from your GP | Is not clear about all fees and costs |
| Offers support for the long term | Has no clear refund policy |
A medical program adds one more check. You can confirm that a doctor or nurse practitioner is registered, and see their current registration status, with the "Look up a health practitioner" search on the Ahpra and National Board websites.
Where Everyday Habits Fit
Whatever the program, the day-to-day work is the same: a healthy diet built on the five food groups, regular physical activity, and habits you can keep up. The program adds assessment, a plan and follow-up around that work. For practical ideas, see our guide to everyday habits that support weight loss.
How the Process Works at Burst Health
Burst Health offers telehealth consultations for weight loss. The process has three steps:
You fill out a secure online questionnaire, providing details about your medical history and current health.
You are connected with an Australian-registered doctor or nurse practitioner who will review your case. The practitioner will call you to discuss your situation, review whether treatment is clinically appropriate, explain any options and potential side effects, and answer your questions. If needed, they may follow up with a few more questions.
If a practitioner determines that treatment is clinically appropriate for you, the treatment is shipped directly to you. Deliveries are discreetly packaged.
No in-person consultation is required: the assessment is completed online. Australian-registered practitioners support you throughout. Outcomes vary between individuals.
Frequently Asked Questions
Is there one best medical weight loss method?
No. Australian guidance does not name one best method for everyone. It bases the treatment path on your BMI, your waist measurement and any weight-related health conditions. Every path includes changes to diet and physical activity, and a registered practitioner decides whether anything more is suitable for you. Outcomes vary between individuals.
What treatment can a medical weight loss program include?
Treatment for obesity in Australia can include a lower-energy diet, more physical activity, weight loss medication and bariatric surgery, often with support from a dietitian, exercise physiologist or psychologist. Any medication is used alongside eating less and moving more, has side effects and is not suitable for everyone. A registered practitioner decides what fits after assessing you.
What qualifies me for medical weight loss in Australia?
A practitioner looks at your BMI, waist measurement and any weight-related health conditions, which Australian guidance uses to set how intensive treatment should be. The practitioner also asks about your medicines and what you have already tried, may ask for tests or an in-person check first, and may recommend a different path.
How do I choose a medical weight loss program in Australia?
Look for a program led by registered practitioners that assesses your health first, builds the plan around a healthy diet and physical activity, schedules follow-up and welcomes input from your GP. Victorian Government advice also says a good service is clear about all fees and its refund policy. Be wary of any program focused on losing weight in a short time.
How much does a medical weight loss program cost?
Costs vary between providers, so ask for every fee in writing before you sign up: the first consultation, follow-up appointments, any treatment, tests and delivery, the payment schedule, and the cancellation and refund terms. Victorian Government advice says a good weight management service gives details of all fees and costs of additional items, and a clear refund policy.
Can I do a medical weight loss program online?
Yes. Many medical weight loss programs run by telehealth, with the consultation by phone or video instead of a clinic visit. Telehealth is not right for every consultation, and a physical examination may still be needed (Medical Board of Australia). A practitioner may ask for an in-person check first. Your usual GP is another place to start.
