Guests receive the same level of medical care as in longer stays. Daily vitals are monitored, two medical consultations are included, and the therapy voucher lets you book spa treatments each day.

Three weeks give the body enough time to shift fully into fat metabolism and trigger meaningful cellular repair. Medical oversight follows the same rigorous standard as the longer formats. The €45 daily therapy voucher, cultural program, and fitness facilities are all included.

A therapy voucher of €45 per day covers massages, physiotherapy, and complementary treatments of your choice. The cultural program of concerts, lectures, and guided walks runs throughout the stay.

Buchinger Wilhelmi Überlingen, in detail

01
The property
Buchinger Wilhelmi Überlingen is the original fasting clinic, founded over a century ago by Dr. Otto Buchinger. The clinic sits high above Lake Constance in southern Germany. From here, views stretch across the water to Mainau Island and the snow-capped Alps. More than 6,000 guests visit each year, and over half return regularly.
The Buchinger method centres on therapeutic fasting supported by integrative medicine. Each stay combines medical supervision, daily health monitoring, and physical therapies. A cultural program of concerts, art workshops, and guided walks rounds out the experience. The clinic holds ISO 9001 certification and employs over 300 staff, including 20 specialist doctors.
More on the property
Now run by the fourth generation of the founding family, the clinic continues to publish peer-reviewed fasting research. It remains the largest clinical centre for therapeutic fasting studies worldwide.

02
What is the Buchinger therapeutic fasting method?
Dr. Otto Buchinger developed his therapeutic fasting method over a century ago. The approach is built on voluntary food abstinence, during which the body shifts to burning fat reserves. This metabolic switch activates autophagy, the body's deep cellular cleaning process.
Every stay follows a structured rhythm. It begins with a digestive rest day, moves through the fasting phase, and closes with a careful refeeding period. Medical staff monitor blood pressure, blood sugar, and weight each morning. Doctors adjust the program based on daily findings.
More on what is the buchinger therapeutic fasting method?
Buchinger Wilhelmi publishes its results in peer-reviewed scientific journals. Over 100 years of clinical data support the method's effects on metabolic health, inflammation, and longevity. No other fasting clinic can match this depth of evidence.

03
What do you eat during a stay at Buchinger Wilhelmi?
During fasting days, guests receive freshly prepared organic vegetable consommé and pressed fruit juices. Herbal teas and mineral water are available throughout the day. This light intake keeps the body nourished while maintaining the fasting state.
Before and after the fast, the kitchen serves full meals from its Demeter-certified organic cuisine. Buchinger Wilhelmi was the first clinic worldwide to earn Demeter certification for its food. The menu is lacto-ovo-vegetarian, with options for calorie-reduced, low-carb, and vegan diets. Individual accommodations for allergies and intolerances are standard.

04
What are the facilities like at Buchinger Wilhelmi Überlingen?
The clinic is spread across several villas and a main building, all set in parkland above the lake. Interiors use local materials and warm colours to create a calm, residential feel. Around 150 rooms range from 9 m² standards to the 100 m² Mainau Suite with its own sauna and jacuzzi.
Shared facilities include a heated outdoor pool, a fitness studio, and a Kneipp hydrotherapy circuit. The spa offers treatments drawn from Chinese, Japanese, Thai, Indian, and European traditions. An art studio, concert hall, and library add cultural depth to each stay.

Questions we are asked
Atmosphere, prices, alternatives
Where is Buchinger Wilhelmi Überlingen located?
The clinic sits high above Lake Constance in Überlingen, southern Germany. Views from the property stretch across the lake to Mainau Island and the snow-capped Alps. Zurich Airport is about 85 minutes away by car. Friedrichshafen Airport is closer at roughly 40 minutes. Stuttgart Airport takes around 100 minutes. The nearest train stations are Überlingen Bahnhof West and Mitte, both a short taxi ride from the clinic. Airport transfers can be arranged on request.
What programs does Buchinger Wilhelmi offer?
The clinic's core offering is the Buchinger therapeutic fasting method. Fasting stays range from 10 nights (Compact) to 28 nights (Classic Royal). The Classic at 21 nights is the format Dr. Buchinger originally recommended. Classic Light at 14 nights is the shortest full fasting protocol. Two non-fasting options are also available. Time Out runs for 7 nights with organic gourmet meals. Relax is a 3-night introductory stay.
How long should I stay at Buchinger Wilhelmi?
For a first therapeutic fast, 14 nights (Classic Light) is the recommended minimum. It allows one digestive rest day, nine fasting days, and four refeeding days. Returning guests often choose the 21-night Classic for deeper results. The 10-night Compact works as a maintenance fast for experienced guests. If you are unsure, 14 nights is the safest starting point.
Who is Buchinger Wilhelmi best suited for?
Buchinger Wilhelmi attracts guests dealing with metabolic conditions, chronic inflammation, stress, and weight management goals. It also draws healthy guests who fast regularly for prevention and longevity. The atmosphere is calm and medically serious. It is not a luxury spa hotel. Guests who want beach clubs, cocktail bars, or lively social scenes should look at SHA Wellness Clinic in Spain or Chenot Palace Weggis in Switzerland instead.
What is included in a fasting stay?
All fasting programs include accommodation, medical consultations (two per week), daily morning health checks, laboratory diagnostics, organic vegetable consommé and fresh fruit juices, fasting minerals, and a therapy voucher worth €45 per day. The voucher covers massages, physiotherapy, and complementary treatments. Access to the heated outdoor pool, fitness studio, Kneipp circuit, daily exercise classes, and the cultural program is also included.
Is Buchinger Wilhelmi suitable for couples?
Yes, couples often visit together. One partner can fast while the other books a non-fasting Time Out stay with full organic meals. Double rooms, Junior Suites, and the larger suites work well for two. Some Executive and Deluxe rooms have connecting doors. The shared daily rhythm of walks, exercise classes, and evening cultural events gives couples plenty of time together.
How does Buchinger Wilhelmi compare to other fasting clinics?
Buchinger Wilhelmi is the original. No other fasting clinic has over 100 years of clinical data or publishes in peer-reviewed journals at the same volume. MAYRLIFE in Austria and VIVAMAYR Maria Wörth follow the F.X. Mayr method, which focuses more on gut health and diagnostic testing. Buchinger's approach centres on extended caloric fasting and autophagy. The setting at Lake Constance is quieter and more nature-focused than MAYRLIFE's Alpine resort style.
What does a stay at Buchinger Wilhelmi cost?
Prices depend on program length and room category. The 9 m² Standard room is the entry-level option. The 100 m² Mainau Suite with private sauna is the most expensive. Fasting programs include medical care, daily treatments, and all meals. For a current quote, contact us through the enquiry form on this page.
