Our Research and Reports

Innovation is key to our success and we're always working to improve our programs.

A diet backed by science

The CSIRO Total Wellbeing Diet was developed by scientists at the CSIRO and is considered one of CSIRO’s top 10 innovations in its 100-year history, right up there with wifi and Aerogard.

Innovation is in the core of the CSIRO Total Wellbeing Diet and through research into eating habits and lifestyle we strive to always improve our weight management programs. Since we went online in 2014 we have published a number of scientific reports that provide insight into what is proven to be effective when it comes to weight loss.

A decade of success: How CSIRO’s Total Wellbeing Diet measures up

Australia’s national science agency, CSIRO, is celebrating a decade of reducing the population’s waistline through its scientifically backed program, the CSIRO Total Wellbeing Diet online.

New analysis from CSIRO, which tracked the weight loss of members over the 10 years since the launch of the online program, found that 97 per cent of members who completed the program lost weight in just 12 weeks. In total, members of the CSIRO Total Wellbeing Diet online have lost a combined 558,000 kilograms - the equivalent weight of about 46 double decker buses.

Over 1.2 million Australians have been impacted by the CSIRO Total Wellbeing Diet throughout its evolution from the original book to the sophisticated digital platform it is today.

Aussie Diet Downfall

The latest findings from the CSIRO Healthy Diet Score reveals that many Australians are falling short in making nutritious choices for their health and wellbeing. 

Over the past eight years, the average CSIRO Diet Score has hovered around 55/100. However, a closer look at the year-on-year data shows a slight decline from 56 in 2015 to 53 in 2023. Of particular concern is the consumption of discretionary foods, which has surged to approximately 28 servings per week on average. This represents a significant increase of 10 servings per week since 2015.

Long Term Weight Loss

CSIRO recently analysed the long-term weight loss results of CSIRO Total Wellbeing Diet members. The data showed that on average members who complete the 12 Week Program lose 7.2% after 12 weeks, 9% after 6 months and then maintain their weight loss for the remainder of the year. “Super star” members (those who engaged with the tools and features the most) continued to lose weight for a full year, with an average total weight loss of 22.3kg or 21.7% after 1 year.
