"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 wholefoods 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 tools."

What makes Fast Start 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 replacements 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 Program is backed by the CSIRO Total Wellbeing Diet, which is key for healthy weight loss and long-term behaviour change.

Fast Start members will take 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.

Am I still eligible for a refund if I join Fast Start?

Yes! Members who join Fast Start Program they are still eligible to receive the $199 refund^ offer if they adhere to our science-backed criteria. You can learn more about that here.
