What is Buchinger Wilhelmi therapeutic fasting?

Buchinger Wilhelmi therapeutic fasting is a procedure whereby a person voluntarily goes without food for a certain length of time, living mainly on their fat reserves instead. This stimulates autophagy and detox enzymes, resulting in a deep cleansing of the cells and tissue. At the same time, fasting reduces all inflammatory processes, alleviates pain and improves mobility. The success of fasting depends to a large extent on the four-day period at the end of the fast, during which patients at our clinic gradually start to eat normal meals again. During this process, dormant stem cells are activated and new structures built up. It is a period of regeneration (also called rejuvenation) with tremendous therapeutic potential. For Buchinger Wilhelmi therapeutic fasting to take full effect, a stay at our clinic should last at least 10 days.

Fasting can be used to treat numerous diseases (see Indications). It can also be enjoyed once a year if you are a slim and healthy person as a preventive measure, among others for the treatment of risk factors such as obesity (particularly abdominal), hypertension, type 2 diabetes, hypercholesterolemia as well as smoking, a lack of exercise and stress. In addition, there are numerous therapeutic indications for fasting, which are increasingly being documented by scientific research. The long list of indications includes joint complaints and rheumatism, chronical digestive disorders, migraine and many more.

Prevention and regeneration

Some indications are still being researched and, depending on the individual situation, are often treated with nutritional strategies instead of full fasting.

Unfortunately, our clinic does not have the facilities to treat drug addiction and other dependencies, severe alcoholism or eating disorders like anorexia and bulimia.

Buchinger Wilhelmi is situated on sloping terrain and is therefore only suitable to a limited extent for guests/patients who have mobility problems or are reliant on a wheelchair.


All about fasting

Is fasting right for me?

Whether you are healthy, ill or “not quite healthy but not quite ill”, we at Buchinger Wilhelmi have a programme that suits you. The first question you need to ask is whether Buchinger Wilhelmi’s therapeutic fasting or one of our nutritional strategies is the right approach to achieve your goals.

To find an answer to this question, you will be interviewed and given a comprehensive examination by a doctor at the beginning of your stay.

What if I can’t fast? 

If you are underweight, weak or emotionally and physically exhausted, you will be given supplements during fasting. This is also the case if your condition requires strong, complex medication or you have concerns or worries.

For those who cannot or do not want to fast, we offer various nutritional strategies from our purely organic, lacto-ovo-vegetarian cuisine. They range from a wholefood diet with 800 kcal to regimes with a normal calorie count but specific benefits, such as a low carb (ketogenic), high fibre or completely vegan diet. Any individual food intolerances and allergies are taken into account.

As with fasting, an individual programme of supplementary treatments will be put together for you from our wide range.

How do I maintain the effects of my stay once I get home?

Fasting, especially if it is your first time, is an unforgettable experience – a revelation: Many people are unaware that they have this capability and that it can feel so good.

As a result, they are often highly motivated to change their lifestyle permanently. To help them to achieve this, we offer a wide range of talks, demonstrations, individual coaching sessions and seminars on topics ranging from nutrition, medicine and psychosomatics to meditation and being mindful of one’s own health.

To support this transfer of knowledge, we have developed the Fasting Coach, an app with daily, informative films.

If you would like to maintain the positive effects of fasting on your well-being for as long as possible, we can help you to incorporate them into your everyday life:
