Meet Dr Nick Fuller - The University of Sydney
“Everywhere I turned, I’d see celebrities and weight-loss companies spruiking diets that were not only impossible to maintain, but were damaging the metabolism they promised to fix. It’s no wonder so many people fail. And, the damage they leave behind leaves people worse off than when they began.
As a qualified healthcare professional working in this space for more than 15 years, I knew there was a better way.
It’s taken me 15 years to develop the IWL program. I’m thrilled to share with you the best knowledge science has to offer about weight-loss in a way that’s simple and easy to follow, so losing weight and keeping it off, is possible for everyone.”
