If you break it, it isn’t broken. It’s just rearranged.

Most diets are fragile. One bad night and you’ve “blown it”, and suddenly you’re waiting until Monday to start again. SuperFastDiet doesn’t work that way.

Say you start a fast day and end up having wine and pizza with your partner. With most programs, that’s the end of the week. With SuperFastDiet, you just fast tomorrow instead. Nothing is broken. Nothing is ruined. You swap the day and move on.

That’s what “unbreakable” actually means, not that you’ll never have an off day, but that an off day can never derail you.

Part 1

SuperFast
The fasting part, done your way.

SuperFast is the fasting component of the program. But not the kind of fasting you might be imagining. There’s no 72-hour water fast. No extreme restriction. Just a structured, flexible approach to when you eat, built around how your hormones actually function in your 40s, 50s, and beyond.

The method is evidence-based, developed with reference to the research of Dr. Krista Varady, Dr. Michelle Harvie, and Dr. Jason Fung, leading global authorities on intermittent fasting.

What it looks like

  • Structured fast days, manageable, satisfying, nothing extreme
  • Flexible approach so it fits your real schedule
  • Guided by the app, you open it and know what today is

What it doesn't involve

  • Not skipping meals forever
  • Not giving up coffee (just checking in on what goes in it)
  • Not feeling dizzy or miserable

Why it works

Fasting creates the metabolic conditions your body needs to start releasing stored fat, particularly the kind that accumulates around the abdomen during and after menopause.

Part 2

SuperFood
The food part, simple, satisfying, and actually good.

SuperFood is about what you eat, and how it supports your metabolism on both fast days and non-fast days. You don’t need to become a different person in the kitchen. You don’t need to throw out your pantry, stop eating out, or cook separate meals for your family.

What it looks like

  • Whole, real food, nothing exotic, nothing expensive
  • Clear guidance on what to eat on fast days to stay full
  • Dietitian-designed meal plans (included in Guided and Coached)
  • 200+ recipes in the app, quick, practical, family-friendly

What it doesn't involve

  • No calorie counting obsession (the app handles that simply)
  • No “banned” foods or permanent restriction
  • No complicated macros to calculate

Why it works

The food approach supports your fasting windows, manages blood sugar, and reduces the low-grade inflammation that makes fat loss harder during menopause.

Part 3

SuperLife
The lifestyle part, the bit everyone skips and then wonders why nothing lasts.

SuperLife is the part most weight-loss programs don’t include, and it’s the reason many women lose weight only to put it back on. SuperLife covers the mindset, movement, sleep, and daily habits that make your results stick well beyond the program. Not because they’re nice extras. Because they directly affect how your hormones regulate fat storage.

What it looks like

  • Daily habit tracking in the app, one check-in, not a spreadsheet
  • Practical movement guidance that doesn’t require a gym
  • Mindset content delivered through the program
  • Weekly masterclasses on the lifestyle factors that matter most

What it doesn't involve

  • No mandatory daily exercise
  • No boot-camp mentality
  • No pressure to become a different kind of person

What a week on SuperFastDiet actually looks like.

Monday Non-fast day

Eat normally. Open the app for today’s checklist. Catch up on this week’s recipe or masterclass content.

Tuesday Fast day

Structured low-calorie eating. The app tells you exactly what to aim for. 200+ recipe options so you’re never stuck. Community group active online.

Wednesday Non-fast day

Eat normally. Check progress. Today’s habits logged in 2 minutes.

Thursday Non-fast day

Live group coaching call (Guided/Coached), 30–45 minutes. Or catch the replay later this week.

Friday Fast day

Same as Tuesday. Dietitian-designed meal plan option available. Weekend prep section in the app.

Saturday Non-fast day

You’re allowed wine. You’re allowed a meal out. The program was built for real life, not a controlled laboratory.

Sunday Non-fast day

Weekly community event or masterclass replay. Review your week in the app. See your progress.

You’re not doing this alone.

Self-Guided

A community of women doing the same thing you’re doing, weekly events, online catch-ups, and the app guiding you every day.

Guided

Your coaching team. Real women who’ve used this program and now run your weekly group calls, accountability sessions, and live Q&As.

Coached

A personal coach who knows your name, your goals, and your history. Two sessions a month, plus direct access between them.

Yes, SuperFastDiet was specifically designed with the hormonal reality of menopause and perimenopause in mind. The fasting methods are not extreme, and the nutrition approach actively supports the hormonal changes happening in your body. Dr. Reiner’s medical involvement means every aspect of the program is informed by clinical experience. As always, we recommend speaking with your GP if you have specific health concerns.

Most fasting approaches aren’t calibrated for women over 40. The protocols in SuperFastDiet are flexible and evidence-based, not derived from research done primarily on younger men. Most members report that fast days become significantly easier after the first two weeks.

No. There’s guidance in the app about what to include and avoid during your fasting window, but giving up coffee is not a requirement for most members.

The program is built for real life. There is guidance for managing fast days around travel, social events, and holidays. Most members describe the flexibility as one of the program’s biggest advantages.

Most members report noticeable changes within the first two weeks, energy, bloating, and early weight change. Visible body composition changes typically become apparent from weeks 4–8 onwards. Results vary by starting point, life stage, and adherence.

You don’t have to keep it all in your head. The app does that.

Open it in the morning. See your day. Your fasting window, your calorie target, today’s recipe, your habits to tick off, your progress from last week. Everything in one place. Nothing to figure out.

Phone mock

For the sceptics.

“I thought this was another diet that would work for two weeks and then I’d be back where I started. I’d tried Weight Watchers, Lite n’ Easy, personal trainers, everything. I was convinced nothing would actually work for me at 58. But something about the flexibility made sense. I could have wine on Saturday. I could go out for dinner. And somehow, eight months later, I’ve lost 23kg and I’m not white-knuckling it. That’s the difference.”
