Why Fast Start works
Fast Start supports both your body and your habits.
The high-protein, low-GI shakes help you feel fuller for longer, reduce cravings and support stable blood sugar levels — making it easier to stay consistent in the early weeks.
Unlike shake-only plans, Fast Start is backed by decades of CSIRO research into nutrition and behaviour change.
It helps you build better eating habits alongside weight loss, setting you up for results that last beyond the first month.

Meal Replacement FAQ's
What is in the Fast Start meal replacement shake?
Our CSIRO-backed meal replacement shakes are created with high-quality ingredients that provide a balanced combination of protein, carbohydrates, fats, vitamins, and minerals to ensure your nutritional goals are met. The meal replacement shakes are high in fibre, gluten-free and contain no artificial colours, flavours, sweeteners or preservatives.
What flavours are in the Deluxe Edition Fast Start 3 Week Starter Pack
Our Deluxe Edition of the Fast Start 3 Week Starter Pack is the deliciously deluxe way to lose weight faster with the CSIRO Total Wellbeing Diet. The Deluxe Edition includes:
- Total of 42 Fast Start Shakes (meal replacements)
- 10 x Cookies & Cream shakes
- 10 x Butterscotch shakes
- 12 x Chocolate shakes
- 12 x Vanilla shakes
- Free Shaker bottle (colour and style may vary to the picture)
Are the Fast Start meal replacement shakes dairy-free, gluten-free or vegan?
Our Fast Start Shakes are gluten free, however, they are not dairy-free or vegan as they do contain milk and soy-based ingredients.
What makes Fast Start Shakes different to other meal replacement shakes?
Our biggest point of difference is in the approach we take to making sure our members are:
- educated about nutrition.
- supported on their weight loss journey.
- able to transition off the meal replacement shakes and onto a varied whole foods diet.
Meal replacement shakes alone aren't a long-term solution to weight loss because most people will revert to their original diet once they stop having shakes. The Fast Start meal replacement shakes are combined with the CSIRO Total Wellbeing Diet, which is key for healthy weight loss and long-term behaviour change.
Members who buy Fast Start shakes will use these meal replacement shakes for breakfast and lunch, while eating a CSIRO Total Wellbeing Diet dinner for three weeks. After this, they’ll transition to a complete CSIRO Total Wellbeing Diet meal plan.
How long will it take for my Fast Start Starter Pack to be delivered?
We ship with Australia Post and delivery times vary from state to state. For full information about delivery times, please view our shipping information page.
Can I exchange flavours I do not like?
No, we do not offer exchanges on flavours in our starter packs.
Can I order more Fast Start Shakes?
Yes, when you become a member you can purchase more Fast Start Shakes via our TWD Shop on the member platform throughout your membership.
Who's not suitable for Fast Start Shakes?
Suitability for diabetes
In general, the Fast Start meal plan is not suitable if you have diabetes. However, everyone is different, and we encourage those with diabetes who are interested in the Fast Start meal plan to consult with their doctor first. If you have been cleared by your doctor to join the program, you can click here.
The standard TWD program includes a Diabetes-friendly meal plan for those with prediabetes or type 2 diabetes. If you have type 1 diabetes, it is strongly recommended that you speak with your doctor prior to joining the program to see if the program is right for you. Find out more about the TWD program here.
Is Fast Start suitable during pregnancy or breastfeeding?
The Fast Start meal plan is not suitable during pregnancy.
In general, the Fast Start meal plan is not suitable while breastfeeding, since a reduction in kilojoule intake can decrease milk supply. However, if you are interested in following the Fast Start meal plan, it is important to speak with your doctor first so they can provide personalised guidance.
