Here’s what you need to understand on how IWL works, what makes it different, and which plan fits your situation - before committing to anything.
WHAT MAKES IWL DIFFERENT
Most people who come to IWL have already tried something else. They started strong, then slowly drifted, or the weight eventually comes back.
IWL is specifically designed through research, to address the root causes of weight regain.
Most diets push too much weight loss too fast. Your body fights back by raising hunger hormones and slowing your metabolism.
Instead, IWL gives your body time to adapt before progressing.
Carb restriction, intermittent fasting, elimination diets — they all work, until you stop.
IWL doesn't ask you to follow rules you couldn't maintain forever.
Most diets assume full compliance. But when life disruption inevitably happens, restarting feels like failure.
IWL expects disruption. The habits are simply a baseline to return to, not a test of discipline.

THE SCIENCE
Most diets fail for the same biological reason. These videos explain the science and why IWL is built around your metabolism, not against it.
The metabolic set point explained, and how IWL is built around it.
The Program
IWL is available as:
For most people we recommend starting with 12 weeks of dietitian-led IWL, giving you confidence you're doing it the right way the first time.
After that, most people transition to self-guided Essentials and continue independently. You can toggle between them at any time.

Real Results
Members who'd tried Jenny Craig, Weight Watchers, keto, and fasting... and finally found something that worked.
I was really lucky and never really struggled with my weight until my mid-30’s. After recovering from a significant mental health issue which resulted in rapid weight loss and then rebound weight gain (and then some and then some more), I knew I needed to do something. I tried some commercial weight loss programs and while I lost weight, I was always hungry and then regained it after the loss. It was so frustrating!
I first found IWL in a bookstore. From the start it seemed to make sense. I lost 10kg slowly in my first year and kept it off for 3yrs. I recently had to do my first weight loss month in a long time but it was easy to return to my set point weight which I’d held for a long time.
The principles of IWL are easy to maintain and integrate into everyday life. I am now a really organised meal planner and prepper which has helped with shopping and avoiding food waste.
I have also found a way to incorporate exercise into my life. And found exercise I love! This has included taking up open water swimming and competing in my first open water swim race at Noosa this February. IWL isn’t a diet, it’s a change to your way of life - for the better. See less
I never had to worry about my weight till I reached my mid 50s. Working in a high stress, long hours job, menopause and life in general all started to take their toll and I gained 14kg. I was horrified when I saw myself on a film made for my occupation and vowed to do something about it. I tried a variety of diets and approaches, including calorie counting, intermittent fasting, commercial weight loss companies, they all worked. I lost weight but I couldn’t keep it off and that was my ultimate goal. One day my daughter told me about Dr Nick and his work and gave me Dr Nick’s first book. From the first chapters I was sold. How many times had my friends and I said- “It seems as if there is a set weight your meant to be and you always return to that weight” Here was a program, that showed you how to counteract that by reprogramming the set weight your body thinks it has. So, I got started. Initially I was frustrated because I didn’t see the big weight losses you often get with some of the commercial diets I had tried, however ,I stuck to it, confident that all that research can’t be wrong and soon I saw regular weight loss. Even better , I was able to maintain that weight loss. So, here I am 4 years later, 12kgs down and comfortably able to maintain my new set weight. If I go off the rails, and I do occasionally, I know exactly what to do to get back on track. The online community and app is also very helpful. The best thing is, it’s not a diet, it’s a way of living, a marathon not a sprint and it’s not even hard to do. Nowadays, I actually find it hard to talk about what I do, because it has just become my daily practice. The only thing you have to lose, is the weight you want to lose. Good luck, you won’t regret it, just stick with it, your life will be so much better for it.
A few years ago, I weighed 110 Kg (1.82 metres or 6ft in the old money) with arthritis in both knees. I was asked to participate in an arthritis study by a sports medicine doctor but was told I had to lose 10Kgs first. At roughly the same time, I heard a Nick interview on 2GB Radio, Sydney. Father’s Day was imminent so at my request, my son gifted me Nick’s book, “Interval Weight Loss for Life”. By the time I dropped off the required 10Kgs, the arthritis study was closed so I kept going following Nick’s recommended methodology closely and approximately 2.5 years later, I’m a trim 88 Kgs (waist reduced from 40 to 34 inches). A bonus is 2 lots of reductions in daily blood pressure medication. 2.5 years later, I’m still 88Kgs (keeping it off is the other half of the weight loss challenge in my opinion), my knees are constantly saying “thank you” and still challenging myself at the gym 4 – 5 x per week. I will be 70 years old in 2021 and am continuing to enjoy life. A further bonus – both men and women who haven’t seen me for a few years, compliment me on how “good” I look!! No complaints, let me assure you.

Common Questions
Answers to what usually comes up on the consult call so you can go in prepared, or skip straight to a plan.
If something comes up, let your dietitian know — they can often work around it or adjust the plan. If needed, you can pause and come back when the time is right.
There is almost always a reason we can trace back to. If you're on Essentials, reach out to community dietitian support and they'll help identify what's getting in the way. If you're on Plus, let your dietitian know and it will be escalated to Dr. Nick directly. We'll work to resolve it — and if there's something outside our scope that requires specialist management, we'll refer you appropriately.
Yes. You can toggle between the two at any time. All your data and progress carries across.
You're assigned automatically when you start. If you have a specific request or would prefer a different dietitian, reach out to support and we'll arrange it.
Yes. Conditions like menopause, diabetes, and GLP-1 use are very common amongst our clients and our dietitians are experienced managing them.
For GLP-1 users specifically, IWL is very effective alongside it — the lifestyle and habit foundation it builds is what allows you to eventually come off it.
For significant medical conditions requiring specialist care, IWL can run alongside that support but should not replace it — this will be discussed on your discovery consult call.
IWL Plus is priced in line with standard private dietitian rates, with the option to pay weekly or upfront for the initial 12 weeks. IWL Essentials is our more affordable self-guided option. Exact pricing will be confirmed on your discovery consult call.
Please find the full guide here → Health insurance guide.
IWL can be cancelled anytime — both Plus and Essentials. You'll retain access until the end of your current billing cycle. Cancel through the app, or email your dietitian or support if you need help.
IWL works best when you have a reasonably stable window ahead of you — at least one month, ideally three, with no major travel, events, or disruptions on the horizon.
Busy is fine. Managing work, caring for children or elderly parents, a full social calendar — these are all workable. Many people find the structure and routine of IWL actually helps organise life and reduce daily decision fatigue.
If life is in a period of genuine upheaval right now, it may be worth waiting for a clearer window. Starting at the right time gives you the best chance of making it stick.
