Preparation for therapeutic fasting
Please fill out our medical history form carefully when you register and submit it to us up to one week before the start of the fast.
Our medical team will check whether there are any exclusion criteria for fasting and will contact you again in advance if there are any questions.
If you have any questions, whether of a medical or organizational nature, please feel free to contact us at any time.
Preparation days: reduce your consumption of food, coffee and sweets. You will receive detailed information on this from us after your registration.
Fasting days at the Hufeland Clinic
Fasting with us is possible on an outpatient basis and with a stay in the clinic
Your fast at our hotel is always medically supervised. This includes a detailed consultation with a doctor and a blood test at the start of the fast.
For guests who suffer from high blood pressure or type 2 diabetes mellitus, for example, regular monitoring and checks are included during the fast.
The medical department is staffed 24 hours a day, 7 days a week and is available for you at all times.
On the fasting days, you are allowed to consume tea, water, fasting juice and fasting broth. Please inform us of any food allergies and intolerances in good time. Our nutritionists will be happy to answer any further questions you may have.
Our fasting program is framed by lectures on the topics of fasting, intestinal health and nutrition.
You can also take advantage of relaxation, exercise, mindfulness sessions, painting therapy, QiGong, meditation and yoga at any time.
Breaking of the fast and restorative days
We plan the breaking of the fast according to the length of your stay.
Experience has shown that most fasters feel safer if they already do part of the build-up days with us at the clinic.
In principle, however, we adapt to the individual wishes of our fasting guests with regard to the length of the fasting and build-up days and are also flexible in the event of last-minute changes during the fast.
A transition from therapeutic fasting to alkaline fasting is possible at any time
If we are not fully booked, individual build-up or alkaline fasting days can also be booked.
Reflect: What has changed? What will you take with you? What positive experiences will you continue to take to heart in the future?
Healing fasting according to Dr. Buchinger at the Hufeland Clinic Bad Mergentheim is not a zero diet. Every day, 200 - 300 kilocalories are consumed - in the form of fasting juices and a fasting vegetable broth, which is always freshly cooked. In addition, the consumption of herbal teas and water is permitted.
Basic fasting, on the other hand, involves three delicious meals a day. The alkaline fasting cure promotes vegetables from a side dish to the main course and thus relieves the body. This is accompanied by plenty of non-carbonated water and/or diluted herbal tea. During alkaline fasting, acid-forming foods are avoided with the aim of bringing the acid-base balance back into a healthy equilibrium.
Fasting according to Dr. Buchinger can be done alone or in a group at the Hufeland Clinic. Our experience has shown that the positive fasting experience is enhanced by the sense of community in a group. This is why we offer specific group dates (courses start on Saturdays).
You are also welcome to book your fasting stay separately from the group offers (flexible choice of dates).
Fasting is good for the body, mind and soul and has an individual effect on each person.
Fasting once or twice a year is certainly recommended. More than 3 months for 7 days is not recommended.
The optimal fasting duration is individual. We recommend a fasting period of at least one week. Longer periods are also possible, depending on the effects you want to achieve. We also attach great importance to the subsequent build-up days and therefore also support you during this phase of the fast.
Yes. Emptying the bowels flushes toxins out of the intestines, which can otherwise lead to side effects (such as headaches and a feeling of hunger); in the worst case, to re-intoxication of the body.
In our clinic, we use Glauber's salt. The ideal amount of Glauber's salt for you is determined together with the fasting supervisor during the introductory consultation. Afterwards, a bowel cleansing with enemas or the colon hydrotherapy we offer is recommended every two days.
As a participant in a fasting cure at the Hufeland Clinic, you will receive medical care, starting with an intake consultation. Depending on the fasting arrangement and your personal situation, we will also prepare a blood count. As a clinic equipped for internal medicine, we also have the option of further diagnostics, e.g. ECG and ultrasound examinations. If you have any pre-existing conditions (e.g. diabetes or high blood pressure), you will be monitored more closely. In any case, our medical team is available to you at any time should you experience any side effects or discomfort during our fasting offers.
In medical emergencies, medical staff are available around the clock (you can reach them at night via an emergency bell). There is a doctor on call.
