"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."

The science behind Fast Start

To assess the effectiveness of our Fast Start Program, we conducted a study with obese and overweight Australians who identified as cravers, and the results were outstanding.

On average, participants that completed the study lost 4.1kg in the first three weeks of supplementing their diet with the meal replacement shakes, and achieved a clinically-significant weight loss of 5.9 kg after six weeks.

On top of this, 80% of participants reporting feeling better at controlling their cravings by week 3.

How long will it take for my Fast Start Starter Pack to be delivered?

Who is the Fast Start Program suitable for?

Fast Start is designed for people who battle with cravings, are overweight and obese and need a simpler way to begin losing weight.

The Fast Start Program uses a formulated meal replacement shake and is not to be used as a total diet replacement.

Fast Start is not suitable for pregnant or breastfeeding women or children under 18 years of age. If you are over 65 years of age, have any medical conditions or are taking any medication consult your doctor before starting the Fast Start program.

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 beauty of the Fast Start Program is that it is backed by the CSIRO Total Wellbeing Diet system, which is key for healthy weight loss and long-term behaviour change.

On 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 are still eligible to receive the $199 refund reward if they adhere to our science-backed criteria. You can learn more about that here.
