Join 108,000+ Super Squad members building lasting weight-loss habits with our doctor-led Foundation platform. Designed for women whose bodies have changed.
You've tried what worked for other people. It didn't work for you. You're eating well, exercising, doing everything right, but the scale won't budge. You're not broken. You're not lazy. Your metabolism has changed, and your approach needs to change with it.
Maybe you've lost the weight five times. Maybe fifty. You stick to the plan, you see results, you feel amazing. Then the moment you stop, it all comes flooding back. The weight, the frustration, the shame.
Tired of tracking every calorie. Tired of meal prep on Sundays. Tired of apps telling you to eat 1,247 calories when you're starving. You don't need another complicated system. You need something that fits your real life.
Here's the truth, it's not your fault.
The diet industry sold you temporary solutions to a permanent problem. Quick fixes. 30-day challenges. Before-and-after photos that never mention what happens after the after. And if you're over 40, most programs weren't even built for you. They were designed for a 30-year-old metabolism. The rules changed. Your body changed. The programs didn't update.
SuperFastDiet Foundation was built for women like you.
A complete framework, not a rigid diet. Three pillars work together so you can lose weight, keep it off, and still live your real life.
A flexible fasting approach designed for your body now. Choose whichever method fits your life. Switch anytime as life changes.
What to eat, when to eat it, and how to stay full on fast days. No hours in the kitchen, no cooking separate meals for the family.
Mindset, movement, and lifestyle practices that cement results and keep them off. Not perfection. Not rigid rules. Just sustainable practices you can maintain.
Most programs give you 100 rules to follow. Foundation gives you a flexible framework that adapts to your life, your hormones, and your body. One system. Three pillars. Built for you to keep.
Most diets are built on restriction. Cut calories. Eliminate food groups. Track everything. They work, for a while. Then they don't. Here's why.
For a while it works. You lose weight. You feel in control. Then, every single time, this happens.
Your body thinks you're starving (because you basically are). It slows down to conserve energy. Weight loss plateaus.
Nobody sustains extreme restriction forever. Eventually you eat the thing. Then the guilt spiral begins.
A birthday. A holiday. A stressful week. The rigid rules can't bend, so they break.
Nothing you did was sustainable. The diet ended. Your old habits returned. And here we are again.
You're not restricting what you eat. You're choosing when. No forbidden foods. No calorie counting. No complicated meal plans.
Consistent breaks from digestion train your metabolism to access stored energy efficiently.
Insulin sensitivity improves. Hunger hormones regulate. Your metabolism doesn't crash, it optimises.
Eat during your window. Close your window. Simple enough to do forever, flexible enough to handle real life.
Not a 30-day challenge. A way of living that supports the body you want, permanently.
Intermittent fasting isn't a diet. It's working with your body's natural rhythms instead of against them. That's why it's sustainable where other approaches fail.Dr. David Reiner, FANZCA · Medical Director, SuperFastDiet

"Victoria tried everything to lose weight but always ended up breaking her diet and regaining. Now she has lost those stubborn 10 kilos that plagued her life, for good, finding part-time dieting unbreakable."
Victoria is proof that even the co-founder of SuperFastDiet struggled with yo-yo dieting before finding this approach. Every diet worked, until it didn't. Every win was followed by a regain. She was exhausted.
10kg later, she's kept it off because the method is unbreakable. You can't fall off a wagon that doesn't exist. The ice cream? She still eats it, during her eating window. That's the whole point.
Victoria Black · Co-Founder, SuperFastDiet
"I was thinking about retirement and was concerned that if I didn't shed the extra weight, it would be harder to manage. I have not looked back since joining SFD."
Anita found SFD in late August 2021 and has lost 19.5kgs, maintaining her goal for years. With the help of her coach and coaching programs, she's changed her life for the better.
She's learned to love herself for who she is, gained confidence to do things she never thought possible, and now deals with obstacles much easier. She achieved her 'Big Why' of losing weight and being full of energy for retirement.

"I waited for the form to ask for my credit card details, when it didn't I signed up. I was so happy that I cried with joy then danced the day I reached my goal of 60kg."
Jenny was sceptical after trying other programs with no support. Her big why was wanting to like herself again. Since joining she's gifted 15kg and had a beautiful a-ha moment when she didn't recognise herself in the mirror.
She finally saw herself the way her husband always said she looked. SFD truly changed her body, mind, and soul. It's her new way of life - she'll never be on a diet again.

Foundation isn't another influencer-created diet trend. It's a medically sound, science-backed approach led by Dr. David Reiner, a practicing Australian anaesthesiologist with 27+ years in medicine and over 20,000 patients.
I was a doctor who couldn't fix himself with the advice I was giving patients. That told me the advice was wrong, not the people trying to follow it.
Dr. Reiner struggled with his own weight for years despite textbook medical advice: eat less, move more, avoid fat, count calories. Nothing worked sustainably. That personal frustration led him to research intermittent fasting, and the evidence was undeniable.
You're not just getting a program. You're getting guidance from the world's leading researchers and practitioners in intermittent fasting, nutrition, brain health, and women's wellness.
Canadian nephrologist. Author of The Obesity Code and The Complete Guide to Fasting. Has taken thousands of patients through his IF protocol.
Associate Professor of Nutrition, University of Illinois-Chicago. The global go-to scientist for intermittent fasting research.
Award-winning UK research dietitian. Author of The 2 Day Diet. 17+ years specialising in diet and exercise for weight loss.
Medical practitioner, brain-health expert, and best-selling author. Translates complex neuroscience into practical tools.
GP, television presenter and media personality with a passion for health and weight management.
30+ years' experience. Director of Northern Beaches Diabetes and Weight Management.
Try Foundation for 90 days. Follow the program. Build the habits. See how your body responds. If you're not satisfied for any reason, we'll refund 100% of your payment. No questions, no hoops, just email us.
Why 90 days? Because real change takes longer than 30. We want you to get past the initial adjustment, build the habit, see actual results, and decide if this is your forever approach. We win when you win.
For a limited time, women who join Foundation as a Founding Member get the program at a reduced price.
No. Foundation is a lifestyle framework built on intermittent eating, not a temporary diet with complicated rules. You're choosing when you eat, not drastically restricting what you eat. Because it's simple and sustainable, it becomes how you live.
Guided includes everything in Self-Guided, plus weekly group coaching sessions with a real coach, live Q&A, and coach-led community check-ins. It's the package most women choose.
Coached includes everything in Guided, plus fortnightly 1:1 coaching calls (6 calls included in first 3 months), personalised guidance, and priority support. Best if you want hands-on help and someone who knows your full story.
Group coaching is a weekly live group session with one of our trained coaches. You can attend live or watch the replay. In each session you can ask questions, share where you're stuck, and get real-time support. Coaches also drop into the Super Squad community between sessions.
It's not 1:1 coaching. It's a supportive group format where you learn from other members on the same journey.
Not if you're doing it right. During your eating window you eat satisfying, nourishing meals. Most members find hunger naturally decreases as your body adapts. Plus, black coffee, tea and water are fine outside your window, which helps more than you'd think.
Yes. Foundation isn't about restriction. It's about timing. Want pasta? Eat it during your window. Craving chocolate? Have it during your window. Birthday party? Enjoy the cake during your window.
Real members still enjoy ice cream, bourbon and cola, Vegemite toast, roast dinners. They just time it within their eating windows.
Yes. SuperFastDiet Foundation was designed for women whose bodies have changed. The program includes menopause-specific guidance formulated by our medical team. Intermittent fasting can be especially effective during hormonal changes because it helps rebalance insulin sensitivity and supports metabolic health.
Over 108,000 women, many over 40, have seen results. This isn't adapted for menopause. It was built for it.
If you're on medication or have specific health conditions, consult your doctor before starting. We provide resources to help that conversation.
If Foundation isn't right for you, we'll refund your payment in full within the first 90 days. To qualify for a refund, we ask that you actually use the program: log into the app for at least 60 days, attend at least 6 weekly group coaching sessions (Guided and Coached), and complete the Level 1 onboarding checklist.
The guarantee is there because we believe in the program. It also asks you to give it a fair chance.
Most members notice changes within the first 2 to 4 weeks: increased energy, better sleep, clothes fitting differently. Weight loss varies, but typical results are 0.5 to 1kg per week once your body adapts.
Real examples: Tracey lost 24kg in 33 weeks. Rebecca lost 21kg in 28 weeks. Jenny lost 15kg and found joy.
At the end of your Founding Member access (6, 9 or 12 months depending on your package), you'll be invited to continue on a standard monthly subscription at the regular package price. There's no auto-renewal surprise. We'll email you a month before your access ends so you can decide.
Yes. Start where you are. Many women begin with Guided for the support, then drop to Self-Guided once their habits are cemented. Others upgrade to Coached when they hit a stuck point. The program is the same, you're just dialling support up or down.
Yes. Foundation lives in your phone. Everything you need in one place: eating-window tracking, fasting timer, today's plan, 800+ recipes, habit tracker, progress insights, full access to community and coaching.
Foundation is a medically sound approach led by Dr. David Reiner, FANZCA, and backed by global fasting researchers. We always recommend consulting your doctor before starting, especially if you take medication (particularly for diabetes or blood pressure), have a history of eating disorders, are pregnant or breastfeeding, or have specific medical conditions.
We provide research summaries and protocol details you can share with your doctor.
You're not broken. Sustainable beats perfect every time. 108,000+ women in the Super Squad are doing this with you, real women like Victoria (10kg), Anita (19.5kg), Jenny (15kg), Tracey (24kg) and Genevieve (35kg) who've been exactly where you are. This could be the last time.
