How Fast Start Shakes work with the Total Wellbeing Diet

Fast Start Shakes are incorporated into the diet plan in a phased manner. The first three weeks involve 2–3 shakes per day and then from the fourth week onwards, you transition onto the regular Total Wellbeing Diet program.

Week 0: Add the Fast Start Starter Pack to your order when you select your membership length. Your Starter Pack will include a shaker and 42 meal replacement shakes. You can also buy more shakes from the Member Shop after joining. 

Weeks 1 to 3: The program begins with 2–3 Fast Start meal replacement shakes per day depending on your energy needs. These shakes will replace your breakfast and lunch meals, but you'll have a delicious Total Wellbeing Diet dinner in your meal plan and can snack on fruit and unlimited veggies. 

Weeks 4 to 6: Once you hit this stage, you will re-introduce breakfast and lunch and include more snacks and even indulgences! If you need it, you do have the option to replace breakfast with a Fast Start Shake.

"The meal replacement shakes really curbed my cravings during the often challenging first three weeks of a program. The shakes were easy and convenient, and filled me up, so it was easy to say no to office morning teas and end of week takeaways. The transition to the whole foods program was also critical in me not falling off the wagon, and I was able to keep that confidence and drive with the help of the CSIRO Total Wellbeing Diet tools."

Frequently asked questions

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.

You can view a list of ingredients here.

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.
