Refundable Membership Fees

You can get a refund of your fee if you successfully adhere to the 12 Week Program

To motivate you to give everything you've got on the CSIRO Total Wellbeing Diet, we offer a refund to members who complete and adhere to the 12-week program.

Our research shows that the members who receive a refund lose the most weight and report greater satisfaction and increased feelings of success. Key results include:

  • Refunded members lose on average 54% more weight than other members⁺
  • That amounts to an extra 2 kg over the 12 weeks of the program⁺
