The protocol
Four systems. One week. Nothing left running on its own.
Z4 is not a diet with extras attached. It is four proven approaches run in parallel, every day, under supervision — because the body does not fail in one place at a time.
People ask what the 4 stands for. It is the four parts of you that the protocol works on at the same time: the physical body, the mind, the energetic body and the immune system. They are interconnected. Treat one and you get a temporary result; treat all four and the result tends to hold.
The regime in its full form is strict. It occupies most of the day, and it is meant to — you are not here to fit healing around a schedule. What it is not is extreme. Movement is mild and adapted, the food is abundant if unusual, and everything is supervised by people who have run this several hundred times.
The four parts
What runs in parallel
Body
The body is the vehicle you get for one lifetime. We rebuild it from the inside — a Gerson-derived juicing regime, light structured movement morning and evening, and a daily hour of easy cardiovascular work in the open air.
Mind
Everything you experience is filtered by the mind before it reaches you. We work on both the conscious and unconscious side of it — breathing techniques, guided focus, NLP and hypnosis where useful — so the change outlasts the week.
Energy
Every guest receives a four-day bioenergy therapy sequence according to the Domančić method, plus morning and evening aura balancing. This is the layer most programmes leave out, and the one guests most often feel first.
Immunity
Cold showers and lake swims following the Wim Hof method, paired with breath work and deliberate rest. The aim is a measurable jolt to the immune system and a nervous system that recovers faster under load.
A day inside it
What the week actually looks like
Times shift with the season and with you. This is the shape of a typical middle day — arrival Monday and departure the following Monday are lighter.
- 06:30
Wake, water, first juice
The day opens slowly. Warm water, the first citrus juice, and ten minutes of nothing at all.
- 07:00
Morning routine
The longer of the two daily movement sessions — stretching, joint work and light strength, adapted to what you can actually do.
- 08:00
Breath work
Guided breathing following the Wim Hof method, then the cold shower or, when you are ready, the lake.
- 09:00
Juices through the morning
Roughly ten pressed juices across the day — citrus, fruit and green, in an order your therapist sets for you.
- 11:00
Bioenergy therapy
On four consecutive days, a full treatment sequence according to the Domančić method.
- 13:00
Light lunch
A soup or a raw bowl. Small, deliberate, and enough.
- 15:00
Hour of power
Easy cardiovascular work outdoors — usually a walk around the lake at a pace you can hold a conversation at.
- 17:00
Lecture or consultation
What is happening in your body this week, and how to keep it going at home. One-to-one time as your package allows.
- 19:30
Evening routine
Shorter movement session, aura balancing, and a review of the day before sleep.
Honestly
Who this is for — and who it is not for
Most people who come to us are living with a chronic condition, recovering after a serious diagnosis, or burned out to the point where rest alone stopped working.
You need to be self-sustaining
The protocol asks you to walk, do light exercise, manage your own room and take care of your own body. If you currently need assistance with daily activities, the group programme is not the right setting — talk to us about the Intense format instead, where you have someone with you throughout.
It sits alongside your doctor, not instead
We ask every guest to keep their physician informed and to continue prescribed treatment. The protocol is designed to support recovery and resilience, and it works best when your medical team knows what you are doing.
Come prepared
The two weeks before arrival matter more than most people expect. When you apply we send a preparation plan; broadly it means:
- Reduce coffee, alcohol and sugar gradually, not abruptly
- Move to lighter, plant-heavy meals in the final week
- Bring recent lab results and your current medication list
- Warm clothes and swimwear — the cold work happens outdoors
- Tell your doctor you are going, and why
