The Clinic is situated high above Lake Constance with breathtaking views over the forest-lined shores of the lake and Mainau Island to the snow-topped peaks of the Alps. Here, in this beautiful, almost Mediterranean landscape, Dr. Otto Buchinger found the ideal setting for his fasting clinic – close to nature, spacious and inspiring.With 6,000 guests from over 60 countries every year, more than 250,000 successful fasting treatments in total, and 100 years of fasting expertise over four generations, Buchinger Wilhelmi is the world’s leading company for therapeutic fasting, integrative medicine and inspiration. The Buchinger Wilhelmi programme is based on therapeutic fasting developed by the clinics’ founder, Dr. Otto Buchinger (1878–1966). This method has been continuously enhanced in cooperation with university research centres and takes into account the rapid progress made in international fasting research in recent years.
In addition to their focus on therapeutic fasting and supplementary nutritional strategies, the clinics offer a wide range of therapies. Above all, however, they are havens of peace and relaxation.


The clinic has approx. 150 rooms, from snug retreats to generously designed suites.

The heart of the complex is the park that was redesigned in 2015 with eight themed gardens, a large Kneipp facility and a heated outdoor pool. A gym, a fitness room with lake views, a multi-functional sports ground, a teaching kitchen, several lecture rooms and other facilities such as a large massage department and a sauna complete the range of amenities. Guests are accommodated in six residences from different epochs: from Villa Fichtenau built in the late Classicist style to Villa Belgrano that was renovated in 2016 and has won several architecture awards.

Programs & Retreats

The 3,000 guests from all over the world who come to stay at our clinic on Lake Constance every year are looked after by more than 300 employees, first and foremost our eight doctors with additional qualifications in different areas (internal medicine, diabetology, nutritional medicine, naturopathy, orthomolecular medicine, homeopathy, TCM, etc.).
A team of 40 employees including nurses, nursing assistants and room personnel provide care and support for guests during their stay.
The range of services includes more than 250 different treatments in the areas of massage and relaxation therapy, fitness, physiotherapy, nutrition and psychotherapy, all performed by certified therapists.
The holistic approach developed by Dr. Otto Buchinger goes far beyond simply reducing the amount one eats. Energizing the body and spirit with physical, contemplative and creative activities plays a very special role during fasting.
The method developed by Otto Buchinger is the most popular form of fasting today. In the course of the clinic’s 100-year history, traditional Buchinger therapeutic fasting has evolved into a highly effective and scientifically documented concept: the Buchinger Wilhelmi programme.
It combines traditional fasting with integrative medicine and incentives for personal development, blending highly advanced diagnostics with naturopathy and complementary medicine, physiotherapy, nutritional therapy, psychosomatic medicine and meditation, as well as many other forms of treatment for the body, soul and spirit.
The programme applied in the Buchinger Wilhelmi clinics does much more than help patients to shed weight, however much this is appreciated: it empowers people to lead a healthy, fulfilled life.
Similar to the original method, the Buchinger Wilhelmi programme also recommends fasting for two to four weeks. This should comprise eight to ten days of fasting with broth and fresh fruit and vegetable juices as well as a cleansing day before and three refeeding days after fasting. However, shorter fasts are also possible with a total of ten nights in the clinic. Those who cannot or do not want to fast can choose between various nutritional strategies with organic, lacto-ovo vegetarian or vegan cuisine.

“Stimulate the spirit and soul, and the body will tone down its demands.”
