A structured 5:2 approach built on protein-centred nutrition - designed to support fat loss while protecting your energy, strength, and vitality.
Most weight loss approaches ask you to eat less. The Radix 5:2 Vitality System asks you to eat smarter, with a consistent weekly rhythm built around protein and nutrient-dense nutrition that actually supports the way your body works.
How it works
A simple weekly structure that brings consistency to how you eat.
Your week, structured.
Two Light Days.
Five Foundation
Days. One clear system.
Tip: Avoid scheduling Light Days on consecutive days or weekends. Mid-week days are easier to stay consistent.
Choose two non-consecutive days —
Tuesday + Friday or Monday + Thursday work well for most people.
✔ 1 Radix Breakfast —
protein-centred start to the day
✔ 2 Radix Protein Smoothies —
structured nutrition across the day
✔ ~800 kcal total —
purposeful, not punishing
The other five days are where
long-term results are built — through consistent, protein-anchored eating.
✔ 1 Radix Breakfast — your
daily anchor
✔ 1 Radix Protein Smoothie —
nutrition with purpose
✔ Protein powder —
included in your 28-day box, use daily
✔ Whole foods —
added around the system based on your appetite and routine
Everything you need. Nothing you don't.
Your Radix 5:2 Vitality System is a complete, structured kit over 28 days — no grocery guesswork, no portion weighing, no tracking apps.
✔ 28 Radix Breakfasts — one every day, your morning anchor
✔ 36 Radix Protein Smoothies — 2 on each Light Day, 1 on each Foundation Day
✔ 30 Protein Powder Sachets — one daily, to reinforce your protein foundation, plus extras in case you need them
Your choice: Plant-based or dairy — select your preference at checkout.
Each Radix serve delivers approximately 20–30g of protein, alongside key vitamins and minerals to support energy metabolism, cognitive function, and immune health.
Most weight loss approaches reduce calories without protecting protein intake. The result? Fatigue, muscle loss, and results that don't last.
The Radix approach is different. Protein contributes to the maintenance of muscle mass — which matters more the older we get. Muscle underpins strength, metabolic function, energy regulation, and long-term independence.
By keeping protein central — even on Light Days — the Radix 5:2 Vitality System is designed to support fat loss without compromising the foundations of vitality.
Built for real life.

That's it. Follow the rhythm and the system does the work.
FAQ
Do I need to count calories?
No. The system is structured so you don't need to. Follow the Light Day and Foundation Day format and the calorie management is built in.
Can I drink coffee or tea?
Yes. Black coffee, long blacks,
herbal tea, and plain tea are all fine. On Light Days, keep milk minimal and
avoid calorie-heavy drinks like lattes or flavoured milks. Stick to water or
zero-calorie carbonated water.
Can I train on Light Days?
Yes, light to moderate training is generally suitable on Light Nutrition Days.
Many people continue with:
- Walking
- Mobility work
- Light cardio
- Technique-focused sessions
However, higher-intensity or heavy resistance training is usually more comfortable on Foundation Days, when energy intake is higher.
The system is flexible. You can schedule your Light Nutrition Days around your training routine so that your more demanding sessions fall on Foundation Days.
What if I'm hungry on Light Days?
This is normal, especially in the first week. Try a large glass of water, herbal tea, or a short walk. Hunger often passes in waves. You can also spread your meals and smoothies more evenly across the day to help manage it.
Which days should I choose for Light Days?
Choose two non-consecutive days: Tuesday + Friday or Monday + Thursday are the most popular choices. Avoid weekends where possible, as social situations make Light Days harder to sustain.
What's the difference between plant and dairy protein powder?
Both options are high-quality protein sources included in your 28-day box. Choose based on your dietary preference or tolerance. Both deliver the same functional protein support within the system.
Why 800 kcal on Light Days, not less?
Traditional 5:2 protocols often use 500–600 kcal, which makes it harder to maintain protein intake and increases the risk of fatigue and dropout. Radix uses 800 kcal to support three structured eating occasions, better protein delivery, and a system that's actually sustainable long-term.
Can I do this alongside strength training?
Yes, and we'd encourage it. The protein focus of the system is designed to support muscle maintenance alongside regular resistance training. Schedule Light Days on rest days or lighter training days where possible.
