A quiet feeling many guests recognise

When was the last time you truly felt clear, light and rested?

Most guests do not come because something is terribly wrong. They come because something no longer feels right.

Fasting is, without any doubt, the most effective biological method of treatment. It is the operation without surgery.

The Benefits of Fasting

What people commonly notice after a fasting retreat

From steadier energy and fewer cravings to better digestion and metabolic balance, these are some of the shifts guests commonly notice after a structured Buchinger fast.

Mental clarity illustration

Steadier Blood Sugar

Often associated with fewer energy crashes and more stable hunger patterns throughout the day.

Observed in structured fasting settings with improved glucoregulation and insulin sensitivity.

Deep calm illustration

Healthier Blood Pressure

Often linked to improved cardiovascular balance and lower physical tension.

Structured fasting has been associated with healthier blood pressure regulation in many participants.

Calm appetite illustration

Fewer Cravings

Many guests notice reduced snacking habits and a calmer relationship with food.

Often observed after the body adapts to more stable blood sugar and reduced stimulus eating.

Digestive ease illustration

Lighter Digestion

Frequently linked to less bloating, less digestive heaviness, and a calmer gut feeling.

Often observed when the digestive system is given more time to rest and recover.

Metabolic reset illustration

Metabolic Reset

Can help the body transition into a more flexible and efficient energy state.

Structured fasting is commonly associated with improved metabolic flexibility and fat utilization.

Structured fasting creates space for the body to shift out of constant input and into a more balanced rhythm.

How It Works

Our five core principles

Every retreat is preventive in nature: structured rest, careful supervision and practical education. These five principles ensure each guest is supported with the same integrity, whether joining for maintenance, learning or early intervention.

Education for Independence

We teach fasting, nutrition, movement and sleep practices so you leave more confident and less dependent on us.

Connection & Small Groups

Groups remain intimate—up to 14 guests—so conversations stay honest and peer support feels natural.

Rest & Sleep

Plenty of rest and a predictable rhythm let your body adapt, recover and sleep more soundly.

Movement & Nature

Gentle walks, stretching and time outdoors keep muscles active and reconnect you to the landscape.

Integrity & Prevention

We act from integrity, screening carefully and focusing on prevention over trends or quick fixes.

“I was extremely satisfied with the teachings our fasting coach Dieter provided, and I learned a lot of new things, such as sketching Mandala paintings and designing my own vision board to represent the future and what I wanted to achieve. A fantastic detox program.”

“The retreat provides very clear and scientific content that explains the scientifically based fasting methodology in great detail. Despite the numerous physical activities, including yoga, meditation, and nature immersions, I did not feel hungry at all. Particularly appealing is the mix of detox and mindfulness.”

The Process

How it works and how you are guided

From your first conversation with us to the follow-up two weeks after you leave, every step is considered.

01

Choosing Your Retreat

You choose the retreat and room that suit you best. Once your place is secured, we guide you through the next steps with clarity and ease.

02

Health Screening & Preparation Call

You complete a short health questionnaire before arrival. You then have a preparation call with Dieter or Hoan to review your goals, health background and the support you may need.

03

Your Retreat
Experience

Five days of fasting, movement, learning and rest. Each day offers structure, guidance and enough space to slow down, reflect and feel supported.

04

Taking The Benefits
Home

You leave with clear refeeding guidance, practical tools and a follow up touchpoint two weeks later, so the retreat can support you beyond your stay.

The Buchinger Method

What your body does,
day by day.

Each stage of the retreat has a purpose. Here is what is happening inside you.

Prep Days

Getting Ready

You eat lighter and set a clear intention. No meat, fried food, sugar or alcohol. Your digestion begins to slow and your mind begins to shift gears.

Day 0

Arriving in Your Body

Baseline health checks. A first spa treatment. A simple plant-based dinner, the last solid meal before your fast. This day is about landing, slowing down and meeting the people you will walk with.

Day 1

Emptying and Switching On

After gentle movement and orientation, Glauber salt clears the bowel. Juices, broth, spa and a sharing circle create the first fasting rhythm. Most guests are surprised by how well they feel.

Day 1 to 2

Cellular Cleanup

With roughly a day of no calories, the body may begin increasing autophagy. Damaged components are recycled. Many guests describe a growing sense of lightness and ease.

Days 2 and 3

Fuel Shift

The body transitions from glucose toward fat and ketones as its main fuel. Movement during this phase signals the body to maintain muscle. Energy often stabilises noticeably.

Day 4

Deep Clarity

Ketosis deepens. Senses feel sharper. Many guests describe a quiet mental clarity they have not felt in years and a changed relationship with hunger itself.

Day 5

The Apple

The first food after the fast is a simple apple, eaten very slowly and with full attention. This moment marks the beginning of the rebuilding phase and feels quietly profound.

Days +1 to +3

Rebuilding and Anchoring

Three days of simple, clean foods reintroduce the digestive system gently. This is where many long-term benefits take root and where new habits find their footing.

The Method

A method with roots. A programme with purpose.

Two traditions, one complete experience. The precision of German fasting methodology meets the depth of Vietnamese healing culture.

German Methodology

Structured fasting inspired by the Buchinger tradition

Rooted in the fasting tradition developed in Germany, our programme follows a clear and well established approach to fasting, education and guided support.

Vietnamese Healing Culture

Local practices that support rest, rhythm and reconnection

Herbal teas, mindful movement, meditation, warm broths and local rituals help guests slow down, reconnect and restore balance.

Guided Experience

Support throughout the entire retreat

You are accompanied throughout the retreat with daily guidance, educational sessions and space for reflection.

Together, these elements create a retreat experience that feels structured, supportive and deeply human.

Made For You

Is this the right retreat for you?

Our retreats are designed for adults who are ready to invest genuinely in their health. Here is who tends to thrive with us.

You will feel at home if…

You are in generally good health and have no contraindicated conditions
You want to understand what is happening in your body, not just follow a programme
You value quiet, unhurried time as much as structured activity
You are open to sharing the experience with a small group
You are ready to bring what you learn back into daily life

This may not be the right fit if…

You are pregnant or are undergoing certain medical treatments. We will let you know before booking if this applies
You expect a luxury spa holiday with no structure or intention behind it
You are looking for a quick fix rather than a genuine reset
You prefer solo time throughout rather than group sharing and evening conversation

We screen all guests carefully before confirming a place. If you are unsure whether fasting is right for you, we are happy to speak with you first.
