Book your fasting week: arrival days, preparation, and dates
Everything you need to know about arrival days, vacation planning, and the process from booking to arrival.

The designated arrival days at Tannerhof are Sunday, Tuesday, and Thursday, aligned with the medical team's practice hours. Arriving on a Sunday helps save vacation days: for the eight-day Basic program, you only need five vacation days, as the following weekend is already included. The fasting period begins the day after arrival with the initial medical consultation. Popular dates in spring and autumn should be planned several months in advance.
The essentials at a glance
- Fixed arrival days on Sunday, Tuesday, and Thursday align perfectly with the medical team's practice hours at Tannerhof.
- Arriving on a Sunday saves valuable vacation days, as the second weekend is already fully integrated into the fasting week.
- The Medical Association for Therapeutic Fasting and Nutrition (ÄGHE), in which Tannerhof physician Burgi von Mengershausen is an active member, recommends a fasting duration of seven to ten days for lasting physiological effects.
- One to three relief days at home optimally prepare your body for the start of fasting the day after you arrive.
Why fixed arrival days support the fasting rhythm
The decision to undergo a Body Detox therapeutic fast at the Tannerhof nature hotel often stems from a desire for clarity and a genuine health reset. To ensure this profound process is medically safe and organizationally seamless from the start, we have fixed arrival days: Sunday, Tuesday, and Thursday. This structure is not an end in itself, but is closely coordinated with the availability of our attending physicians. Since every fasting retreat requires precise medical supervision, this rhythm ensures that your initial consultation takes place the day after your arrival, before the actual fasting phase begins.
- On your arrival day, you will settle into your mountain hideaway, move into your room, and enjoy a light vegetable plate in the evening to ease into your stay.
- On the first day of fasting, the morning after your arrival, a comprehensive medical consultation including a precise bioimpedance analysis will determine your suitability.
- Only after this medical examination does the traditional Glauber's salt—a laxative salt for thorough intestinal cleansing—initiate the actual fasting process.
Beyond medical safety, this scheduling has a subtle psychological effect. By having guests arrive on fixed days, an unobtrusive, shared rhythm emerges. You meet on equal footing, share the initial phase of adjustment, and experience the strengthening power of a community focused on the essentials. This shared dynamic makes the act of abstaining easier and carries you through the first days of the fasting metabolism, while your body learns to switch entirely to its internal resources.
Planning vacation days wisely: Sunday as the ideal start to fasting
When planning a deep regeneration, most people start by counting their vacation days. At the Tannerhof nature hotel, this practical step can be managed quite cleverly, especially when choosing the medically supervised Body Detox therapeutic fast. Arriving on a Sunday is an ideal way to protect your personal vacation balance: since the following weekend is firmly integrated into the eight-day Basic program, your retreat does not require a second week of work.
This well-thought-out rhythm is no coincidence; it is closely woven into the hotel's medical concept. The recommended arrival days of Sunday, Tuesday, and Thursday are precisely aligned with the hours of our on-site medical practice. Since the actual fasting period begins the day after arrival with your medical appointment, the team ensures that your body is optimally supported from the very first second.
- Sunday: Relaxed check-in from 3 p.m., settling into your personal mountain hideaway, and a strengthening vegetable plate in the evening.
- Monday: Medical intake with bioimpedance analysis and the classic introduction to Buchinger therapeutic fasting.
- Tuesday to Saturday: Supervised therapies, guided hikes in the Bavarian mountains, and deep metabolic regeneration.
- Sunday: Mindful reintroduction of food, followed by check-out by 11 a.m. for a relaxed journey home.
With this structure, exactly five vacation days are enough to give your body an eight-day regenerative break. The weekend frames the fasting week harmoniously: you arrive in peace on Sunday, glide into a new rhythm without the pressures of daily life, and return home feeling strengthened the following Sunday. If you choose the more comprehensive ten-day Advanced program, it is ideal to arrive on a Tuesday or Thursday to make the most of the weekends for your own recovery.

Lead time and booking options: How to secure your fasting appointment
Certain times of the year carry a special longing for a fresh start. Early spring and golden autumn, in particular, awaken in many guests the desire to give their bodies a conscious break and leave the old behind. Since these periods are highly sought after for Body Detox therapeutic fasting, we recommend planning well in advance. If you would like to secure your preferred date and the right room at our hideaway in the mountains, the Naturhotel Tannerhof, you should ideally plan several months ahead.
There are two simple ways to start your personal fasting retreat at the Tannerhof.

However, if you would like advice on the various accommodations, medical details, or the appropriate program depth, a personal inquiry will lead you directly to our team, who will take the time to address your individual needs.

A successful start doesn't just begin in Bayrischzell. As soon as your fasting date is set, the phase of mental preparation begins. For the actual start of your fast, we recommend arriving on a Sunday, Tuesday, or Thursday. These days are aligned with our clinic's schedule to ensure your fast begins the following day with a well-supported medical intake appointment. Until then, we will support you with valuable tips for your relief days at home.
What happens after booking: From preparation to arrival
The journey to a new sense of well-being begins long before you arrive in Bayrischzell. In the comfort of your own home, you can gently prepare for your upcoming therapeutic fast with one or two relief days. A light diet of steamed vegetables, apples, or rice signals the upcoming change to your body, relieves the digestive system in advance, and makes the physiological transition noticeably easier. This careful preparation reduces typical transition symptoms during the first few days and paves the way for profound regeneration.
- Arrival and check-in: On your chosen arrival day (Sunday, Tuesday, or Thursday), we will welcome you at the Naturhotel Tannerhof reception from 3 p.m. You can settle into your room or cabin at your own pace and simply arrive.
- The first evening: To round off the transition harmoniously, we will serve you a light, warm vegetable plate in the restaurant in the evening, providing an ideal conclusion to your final day of preparation.
- The start of the fast: Your active Body Detox therapeutic fast begins the following day. After the medical intake interview, you will drink Glauber's salt, which acts as a mineral laxative to initiate a thorough intestinal cleanse and suppress hunger.
With this carefully timed rhythm, we ensure at the Tannerhof that your fasting metabolism, fluid balance, and circulation can adapt in a controlled manner without unnecessary strain. The fasting week schedule carefully structured by our attending physicians provides the medical security you need for your personal retreat. Step by step, the hustle and bustle of everyday life gives way to a deep inner calm.
