Spring Into Weight Loss That Works After 40.
Join 108,000+ Super Squad members for the 12 Week Spring Challenge: our doctor-led program, built for women whose bodies have changed. Start the day you join, build habits that carry you into summer, and keep them for life.
Eating Well, But Nothing Is Shifting?
Your Body Changed The Rules Without Telling You
You’ve tried what worked for other people. It didn’t work for you. You’re eating well, moving more, 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.
Another Spring, Another Fresh Start?
Every spring you promise yourself this is the year. You start strong, you see results, you feel amazing. Then life gets busy and it all comes flooding back. This time, let’s build something that lasts past the season.
You’re Tired Of Complicated
Tired of tracking every calorie. Tired of meal prep on Sundays. Tired of apps telling you to eat 1,247 calories. 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 weight-loss industry sold you temporary solutions to a permanent problem. Quick fixes. 30-day crash plans. 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.
The 12 Week Spring Challenge was built for women like you.
Why Spring? Why 12 Weeks?
Spring is the season of fresh starts. Longer days, more light, more fresh produce and more reasons to get outside. It’s the easiest time of year to build a new habit, and the best time to make it stick before the silly season.
A season built for fresh starts
More daylight, more energy, more colourful food in season. Spring gives you a natural lift, so you start with momentum on your side.
12 weeks is the sweet spot
Long enough to build a real habit and see how your body responds. Short enough to stay focused. A clear finish line, with no pressure to be perfect along the way.
You’re doing it together
Everyone starts on the same day. Same week, same wins, same wobbles. A whole Super Squad cohort in your corner, cheering you through every fast day.
How The Spring Challenge Works (Seriously, It’s This Simple)
A complete framework, not a rigid plan. Three pillars work together so you can lose weight, keep it off, and still live your real life.
Fasting That Works With Your Hormones
A flexible fasting approach designed for your body now. Choose whichever method fits your life. Switch anytime as life changes.
- 2 Day Fast: eat normally 5 days, fast 2 (500 cal each)
- 3 Day Fast: eat normally 4 days, fast 3
- Part Day Fast: a daily eating window (e.g. 12pm to 7pm)
- All flexible. The app helps you pick.
Real Food, Real Life
What to eat, when to eat it, and how to stay full on fast days. Spring produce, no hours in the kitchen, no cooking separate meals for the family.
- 800+ dietitian-designed recipes for fast days and feast days
- Family-friendly meal plans, no separate cooking
- Optional calorie tracking built into the app
- Eating-out guides, entertaining tips, low-cal cocktails
The Habits That Make It Stick
Mindset, movement and lifestyle practices that cement results and keep them off. Not perfection. Just sustainable practices you can keep.
- Daily habit tracker built into the app
- Mindset coaching and brain-health strategies
- Gentle movement guidance, made for spring weather
- Live coach check-ins (Guided) and community events
Why this works when everything else hasn’t
Most programs give you 100 rules to follow. The Spring Challenge gives you a flexible framework that adapts to your life, your hormones and your body. One system. Three pillars. Twelve weeks to make it yours.

Why Restriction Doesn’t Last (And What Actually Works)
Most plans are built on restriction. Cut calories. Eliminate food groups. Track everything. They work, for a while. Then they don’t. Here’s why.
Traditional Plans, On Repeat
Intermittent Eating Changes The Game
“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.”
Real Coaches, Real Check-Ins, Real Accountability
Guided challengers get live group coaching 2 x per week with our team of expert coaches, for all 12 weeks. Live Q&A, real support, and the kind of accountability that helps you show up.
What Guided Group Coaching Looks Like Across Your 12 Weeks

Meet The Super Squad Members Who Started Fresh
The Yo-Yo Dieter Who Built The Unbreakable Method
“Victoria tried everything to lose weight but always ended up breaking her plan and regaining. Now she has lost those stubborn 10 kilos, for good, finding part-time dieting unbreakable.”
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.
Lost 19.5kg and Found Self-Love
“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, lost 19.5kg and has maintained her goal for years with the help of her coach.
Lost 15kg and Found Joy
“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’s big why was wanting to like herself again. It’s her new way of life, and she’ll never go back to restriction.

Medically Led By Dr. David Reiner, FANZCA
The Spring Challenge isn’t another influencer trend. It’s a medically sound, science-backed approach led by Dr. David Reiner, a practising Australian anaesthetist 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.”
