Preparing for Therapeutic Fasting: The Week Before Arrival
How relief days at home, a gentle reduction of stimulants and a little inner preparation make the start of fasting easier.

Preparing for therapeutic fasting means making the week before arrival gentler: gradually cutting back stimulants like coffee, sugar and alcohol, and taking one or more relief days at home — for example as a fruit, potato, vegetable or raw-food day. Naturhotel Tannerhof recommends this quiet transition so the start of fasting becomes easier.
The essentials
- Good preparation makes the fasting start gentler; it is a Tannerhof recommendation, not a rule — how many relief days you take is your choice.
- A relief day is a light, carbohydrate-leaning day at home — a fruit, potato, vegetable or raw-food day — with plenty of calorie-free fluid.
- In the days before arrival, coffee, sugar, alcohol and nicotine taper down step by step; that eases the transition during the fasting week.
- The mental and practical side counts too: easing the calendar, clarifying expectations, and being able to truly arrive.
- The length of stay is booked before arrival; the medical intake consultation follows on the first fasting day, and a telephone medical pre-consultation is available on request.
Why preparation makes the difference
A fasting week does not start with the first cup of fasting tea. It begins at home, in the days before, when everyday life slowly quietens and the body already begins to shift down. People who jump from a busy week into the fast feel the transition more sharply. People who take a few quiet days slide in more gently.
At Naturhotel Tannerhof this preparation belongs to the recommendation, not the mandatory programme. Buchinger therapeutic fasting is the conscious, time-limited abstention from solid food and stimulants, and the more this abstention is prepared, the less abrupt the start feels. The medically guided framework is at Body Detox; the method itself at Buchinger Method.
Preparation is not a nice extra in professional terms either. The Guidelines on Fasting Therapy published by the German Medical Society for Therapeutic Fasting and Nutrition include the relief day as a fixed part of the classical fasting week, which is described as an arc of relief day, several fasting days and rebuilding days.
The relief day: eat lightly before it starts
A relief day is a deliberately light day on which digestion already shifts into a gentler gear. Instead of heavy, abundant food, something mild and easily digestible is on the table, carbohydrate-leaning, low in fat and protein, accompanied by plenty of water and herbal tea. The body receives a first signal that a time of relief lies ahead.
Several variants have proven themselves in fasting practice, and none is better than another. Which fits you depends on taste and tolerance. A reliable guideline describes a relief day of about 600 calories, predominantly from carbohydrates, with at least two litres of calorie-free fluid.
| Relief day variant | What's on the plate |
|---|---|
| Fruit day | Fresh fruit across the day in several small portions, with water and herbal tea. Mild and refreshing, a gentle start. |
| Potato day | Steamed or boiled potatoes, lightly seasoned, with some steamed vegetables. Filling and easy on the stomach. |
| Vegetable day | Steamed vegetables or a vegetable soup, light and alkaline-rich, good for sensitive stomachs. |
| Raw-food day | Fresh raw vegetables and a little fruit, fibre-rich, for those who tolerate raw food well. |
Some people take a single relief day, others two or three. Both are possible. We recommend keeping at least the day or the two days before arrival free, so the transition does not get lost between appointments. How many it becomes is your choice. Ideally the days before are already quieter anyway.
Gently easing back on stimulants
Alongside lighter eating, a second quiet step pays off: gradually reducing stimulants in the days before arrival. Coffee, sugar, alcohol and nicotine belong to the things whose sudden absence makes the first fasting days more noticeable. People who reduce carefully at home take some of the impact out of the transition.
With caffeine, a gradual reduction is more pleasant than an abrupt cut: one cup fewer per day, perhaps the last one earlier in the day. So the familiar caffeine withdrawal headache of the first fasting days stays milder. The same applies to sugar and strongly sweetened foods, which may quieten in the days before, and to alcohol, which may pause entirely in the preparation phase. Reliable fasting sources recommend skipping coffee, alcohol, sweets and nicotine on the relief day itself.
The good thing: this small reduction is not abstention into the void. It is the first part of the relief that fasting is about. Food and stimulants step back, and with them often some inner noise. Many describe that even the preparation days taste different from a normal start of the week.

The mental side: arriving before you arrive
Fasting is more than a diet. It is a caesura, an abundance of time with and for oneself, and one may prepare for that inwardly too. Professional sources speak of the inner tuning that precedes outer preparation. Nothing complicated is meant: a little clarity about why you are fasting, what you wish for the week, and what may safely stay behind.
It helps to ease the calendar before departure and order the last obligations so they do not travel into the hideaway. My hideaway in the mountains means this too: a place where the demands of daily life stay outside for a while. Those who arrive without still being mentally with open items arrive more quickly in truth.
A large expectation may calmly grow smaller. Fasting unfolds individually: some sleep more lightly, others need patience with the transition days. Allowing this openness even before arrival takes pressure away and makes the start softer.
What is organised before arrival
A few organisational things are clarified before arrival, and that adds relief. The length of stay is booked before arrival, online or through reservation. So the time frame in which you fast is set before you even reach the Leitzach valley. Which duration fits you is part of the recommendation: we recommend five fasting days and upward; for first-time fasters, a week with rebuilding is a fine size.
The medical intake consultation takes place only on the first fasting day, that is after arrival. It is holistically arranged, with history-taking, physical examination including bioimpedance analysis and medication review, and beyond that with the question of why you fast, what goals you have at Tannerhof beyond fasting, and what fasting experience you bring. From this conversation, duration and course can be adjusted together with the medical team, for example extended.
If questions remain open before arrival, for example with chronic conditions or ongoing medication, a telephone medical pre-consultation is available on request. So what fits well for you can be clarified beforehand. During pregnancy, breastfeeding and anorexia, therapeutic fasting does not belong in the plan; otherwise, what matters are your own will and readiness to fast.
The arrival day as a soft transition
On the arrival day itself, preparation passes seamlessly into the fasting week. Tannerhof counts this day as a relief day: for dinner, a light vegetable plate ends the day softly. So the arc closes between the relief days at home and the first fasting day, without a hard break.
Arriving may be taken literally here. Bayrischzell, the alpine meadow, the mountain stream and the view to the Wendelstein form the quiet frame in which the fast begins. The Tannerhof taxi brings you up from Bayrischzell station on request, so even the arrival is eased. People who like may use the first evening to really arrive, before the next day brings the intake consultation and the actual start of the fast.
From the first fasting day on, the familiar rhythm carries the week: herbal tea in the morning, a mild vegetable broth at midday, a freshly pressed fruit or vegetable juice in the evening, with plenty of fluid across the day. The fast is accompanied by a deliberately broad spectrum of treatments, from Kneipp alternating affusion, hay flower and aromatic wraps through fasting massage and detoxifying massage with king's oil or acidosis massage to breathing therapy, bioimpedance analysis and, depending on the programme, IHHT altitude training. Movement stays measured, with moderate aerobic and moderate strength training, yoga or a walk at a pace that fits the fast.

Thinking beyond the fast
People who prepare well often think before arrival about the time afterwards. That is wise, because a fasting week unfolds its effect only with a quiet rebuilding and an everyday that carries the experience forward. Over roughly one third of the fasting time comes rebuilding with easily digestible vegetables, fermented foods and conscious chewing.
In the closing medical consultation, what has changed is evaluated, and the nutrition that fits everyday life is discussed. Often Schlanke Tanne Low Carb follows, the in-house low-carb form, as a way to carry the fasting experience into everyday life. Intermittent fasting can also build this bridge, not as a Buchinger replacement but as an everyday form of compact-fasting benefits. So the fasting week gets a beginning, a middle and a transition — and begins, in fact, a week earlier, at home.

FAQs
Preparation has two sides. On one, in the days before arrival, cut back stimulants like coffee, sugar, alcohol and nicotine step by step and take one or more relief days with light, carbohydrate-leaning food. On the other, ease the calendar and prepare inwardly. At Tannerhof this is a recommendation — how much you do is your choice.
A relief day is a deliberately light day before fasting on which digestion already shifts into a softer gear. Tried variants are a fruit day, potato day, vegetable day or raw-food day, each mild and easily digestible, with ample water and herbal tea. A useful guideline is around 600 calories mainly from carbohydrates, plus at least two litres of calorie-free fluid.
Your choice. Some take a single relief day, others two or three. We recommend keeping at least the day or two before arrival free so the transition is not lost between appointments. More days make the entry softer; no specific number is required.
A gradual reduction makes the start noticeably easier. Caffeine is best eased back slowly so the withdrawal headache of the first fasting days stays milder; sugar may quiet down, alcohol can rest entirely during preparation. On the relief day itself, coffee, alcohol, sweets and nicotine are left aside.
The length of stay is booked before arrival, online or through reservation — that sets the time frame. The medical intake consultation takes place on the first fasting day after arrival; from there, duration and course can be adjusted together with the medical team, typically extended.
Yes. With chronic conditions, ongoing medication or uncertainty, a telephone medical pre-consultation is available on request, to clarify what fits for you. The full intake consultation follows on the first fasting day at Tannerhof.
