Choosing a weight loss program can be overwhelming. Some programs focus on meal plans and tracking apps, others deliver ready-made meals, and some offer medical assessment and (where appropriate) treatment and ongoing clinician support.
The right option depends on your health history, goals, budget and how much support you want. This guide compares seven of the most popular diet and weight loss programs available in Australia, with an honest look at what each one includes and who it suits.
Transparency note: Chemist2U operates Weight Loss by Chemist2U, which appears in this list. Pricing and inclusions for all programs were taken from each provider's website in September 2026 and may change. Always check current details with the provider.

How we compared these programs
Each program was assessed against the factors that matter most for safe, sustainable weight loss:
- Clinical oversight. Access to qualified health practitioners who review your health history.
- Personalisation. Whether the plan adapts to your needs, rather than a one-size-fits-all approach.
- Ongoing support. Follow-up consultations, coaching or community.
- Pricing transparency. Clear pricing, inclusions and cancellation terms.
- Flexibility. Lock-in contracts, auto-renewals and ease of cancelling.
- Evidence base. Whether the approach is based on research.

Ongoing consultations ensure that treatment continues to be appropriate and that you have all the support you need.

Frequently asked questions
What is the best diet program for weight loss in Australia?
There is no single best program for everyone. For people who want medical assessment, regular practitioner check-ins and all-inclusive pricing, a clinician-led program like Weight Loss by Chemist2U offers structured support. Self-guided programs such as the CSIRO Total Wellbeing Diet or WeightWatchers can suit people who prefer to manage their own plan.
What is the difference between a diet program and a medically supervised weight loss program?
Diet programs focus on eating plans, tracking and behaviour change, usually without clinical oversight. Medically supervised programs include a consultation with a qualified practitioner who reviews your health history and may recommend a range of options, including lifestyle changes and, where clinically appropriate, weight loss treatment.
How much does a weight loss program cost in Australia?
Costs vary widely. App-based programs start from around $40 per month, meal delivery services often cost over $150 per week, and clinician-led programs typically start from around $250 per month, with pricing depending on the treatment plan and (in some cases) a commitment period.
Do I need to see a doctor before starting a weight loss program?
It is a good idea to speak with your GP before starting any new program, especially if you have a medical condition, take regular medicines, are pregnant or breastfeeding, or are considering a very low energy diet.
Can I claim a weight loss program on private health insurance?
Some programs, such as the CSIRO Total Wellbeing Diet, may be claimable under certain extras policies. Check with your health fund to confirm what your cover includes.
