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 ten 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.”
We know diets don’t work, and they’re dangerous.

What people are saying about IWL
Aisling Fleury
IWL isn’t a diet, it’s a change to your way of life - for the better. I've lost 10kg and maintained it for 3 years.
Brenton Johnson
I discovered the IWL program and it immediately appealed to me. I’ve hit my goal weight and finally feeling good about the decisions I make about my lifestyle, health and diet.
Bet Reichstein
My IWL journey started after reading the books. I was feeling bad, having regained the weight and more from my latest diet, and now in my 60s, was feeling desperate to maintain health and mobility as the years advanced…IWL gave me hope. I’ve now hit my goal weight.
Lorraine Bradwell
Here I am 12kgs down and comfortably able to maintain my new set weight for the past 4 years.
Ben Lindsay
A weight loss of 20kgs and back under 90kgs, I am feeling healthy and fit again. I've never starved myself and I am enjoying what I eat.
Fran Bush
It’s consistent and it works. 79kg to 69kg and maintained for 2 years now.
Chris White
3 years later, I’m still 88kg (22kg down) and my knees are constantly saying 'thank you'. I will be 70 years old in 2021 and am continuing to enjoy life.
