Regular self-monitoring behaviours and tracking tools could be the key to losing weight and keeping it off, according to research from CSIRO, Australia's national science agency. The study initially mapped the total weight loss of 6,602 CSIRO Total Wellbeing Diet members that had completed the 12-week programme. It found 64% lost a clinically significant amount (>5 kilograms) of weight at one year, with a sustained average weight loss of 10.6kg, or 11.9% of their starting body weight. The most successful of this group lost an average of 22.3kg, equivalent to 21.7% of their starting body weight.
To better understand the behaviours resulting in this success, CSIRO scientists conducted a further study to compare the usage patterns of various CSIRO Total Wellbeing Diet platform features. This second stage analysis revealed the perceived importance of tracking, self-monitoring and ongoing education to individuals.
Study participants who achieved weight loss exceeding 10% of their starting body weight used all of the CSIRO Total Wellbeing Diet's tools - weigh-ins, food diary, menu plan, exercise plan, programme content, forum and food search - 50% more than those who lost less than 5% over the same time period.
CSIRO research scientist, Dr Gilly Hendrie said using tools and support frameworks to educate around diet and nutrition was critical for ongoing societal health and lifestyle improvements, especially given that 67% of Australians are currently overweight or have obesity.
"There are no quick fixes when it comes to sustainable weight loss and a healthy lifestyle, and this study helps us to show that weight loss comes from a range of regular actions and positive behaviours,” she explained. “It's repeatedly using Total Wellbeing Diet tools, while developing positive habits, that help people to come back to, and maintain, a healthy lifestyle. We're really happy to have more research that reinforces the critical role that lifestyle and behaviour change plays in long term weight loss and management.”
Other key findings of the study included:
It was most common (14.6% of study participants) for people to lose weight during the first six months of a weight loss journey and then enter a maintenance phase for the remainder of the year
In spite of the maintenance phase, 54% of 738 participants surveyed who had lost 14kg or more had been able to continue weight loss after a plateau
Most people reported that they were still monitoring their weight on a weekly basis (44%), or at least weekly (daily + weekly, 64%)
Members who lost more than 10% of their body weight tended to view menu plans 70% more
After the first 12 weeks, usage of the food diary was 2.5 to 3 times higher over the remainder of the year in members who lost 10% or more of their starting body weight.
CSIRO Total Wellbeing Diet member, Terry from Queensland, reinforced the importance of having ongoing access to the food and exercise tracker, menu plans and Facebook support group, crediting them to helping him maintain his 100kg weight loss for two years and nine months.
"The tools have created habits that are within me and now just part of my lifestyle," said Terry. "Every weekend, I'm using the food tracker to create my own meal plan before spending time in the kitchen to pre-prepare the meals for the busy work week ahead. With a little bit of preparation and accountability, eating well is really easy. There's less room to move off track as you know you already have a nutritious meal ready for you. There's less decision fatigue. It's also important to acknowledge that even though this is ideal, some weeks this doesn't happen. Last year, I let things slide a bit over the Christmas break. Rather than beat myself up, I just decided to simply refocus and reset by going back to basics—logging my weight and tracking my food intake. I was also kind to myself, something I picked up from others in the CSIRO Total Wellbeing Diet Facebook group.
