Same price as Buchinger Wilhelmi Marbella's own site, never more, with an independent expert advisor by your side.
Buchinger Wilhelmi Marbella sits among ancient palm trees on the Mediterranean coast, with views stretching to the Rock of Gibraltar. Founded in 1973 as the sister clinic to the original Lake Constance location, it follows the same therapeutic fasting method developed by Dr. Otto Buchinger over a century ago.
The clinic houses 101 rooms across the main building and Villa Maria. Twelve doctors and around 200 staff members guide each guest through their fasting or diet program. The architecture uses natural materials and warm colours that blend with the surrounding landscape.
Gardens with organic vegetable plots, a heated outdoor pool, tennis courts and walking paths surround the property. The mild Andalusian climate allows year-round outdoor activity.
The property
What is the Buchinger Wilhelmi fasting method?
Buchinger therapeutic fasting is a medically supervised protocol developed in the 1920s. Guests consume organic vegetable broth and freshly pressed juices while the body shifts into ketosis and activates cellular repair processes.
Each stay begins with one to three digestive rest days. The fasting phase follows, lasting from six to twenty-three days depending on the program chosen. Refeeding days at the end gradually reintroduce solid food. A personalised therapy plan accompanies the fast, covering nutrition, physical therapy, relaxation and coaching.
Standard laboratory examinations at the start and end of every stay track measurable health changes. Two medical consultations per seven nights are included. Round-the-clock nursing care and an on-call doctor provide continuous support.
What do you eat during a stay at Buchinger Wilhelmi Marbella?
During fasting, you receive organic vegetable consomme, freshly pressed fruit and vegetable juices, herbal teas and mineral water. These provide essential micronutrients while keeping caloric intake low enough to sustain the fasting metabolic state.
Guests on the Diet package enjoy lacto-ovo-vegetarian wholefood cuisine. Through the CSA initiative with Fundacion Arboretum, the kitchen sources seasonal produce from small farms within 30 km of the clinic. Meals follow Kousmine diet or organic gourmet principles.
Refeeding days after fasting use a carefully structured sequence. You start with light foods like rice and steamed vegetables, then build toward the full Buchinger diet over three to four days.
What are the facilities like at Buchinger Wilhelmi Marbella?
The property spans several acres of Mediterranean gardens with native plants and an organic vegetable garden. A heated outdoor pool overlooks the sea. Tennis courts, a gym and a Pilates pavilion support daily movement.
Indoor facilities include a sauna, library with fireplace and treatment rooms for massage, physiotherapy and Traditional Chinese Medicine. The weekly group programme covers yoga, Qi-gong, Tai chi, Nordic walking, cooking demonstrations, sound baths and evening concerts.
Villa Maria houses the premium suite categories with sea views and private terraces. The main building contains the medical centre, dining areas and standard through superior rooms.

Frequently asked questions
Where is Buchinger Wilhelmi Marbella located?
The clinic sits on Avenida Buchinger in Marbella, on the southern coast of Spain. Malaga international airport is about 60 minutes away by taxi. The clinic can arrange airport transfers on request.
What programs does Buchinger Wilhelmi Marbella offer?
The clinic offers four fasting programs and one non-fasting option. Fasting stays range from 10 nights (Compact) to 28 nights (Classic Royal). The Diet program is a 7-night non-fasting stay built around organic wholefood cuisine. All programs include medical supervision, lab work and a therapy voucher.
How long should I stay at Buchinger Wilhelmi Marbella?
First-time fasters often start with Classic Light (14 nights) or Compact (10 nights). The Classic (21 nights) gives the body time for deeper metabolic changes. The Classic Royal (28 nights) is the most thorough option for guests who want maximum results. Your doctor can advise on the best length during a pre-booking consultation.
Who is Buchinger Wilhelmi Marbella best suited for?
The clinic suits adults seeking medically supervised fasting for weight management, metabolic health or general renewal. It is not a spa hotel. Guests should be prepared for a structured clinical routine with limited food intake. Those looking for a luxury spa with unrestricted dining may prefer Buergenstock Resort or SHA Wellness Clinic.
What is included in a Buchinger Wilhelmi Marbella package?
Every package includes accommodation, medical care (two consultations per seven nights), 24-hour nursing, standard lab panels, fasting provisions or diet meals, and a therapy voucher worth 45 euros per night. Group activities, the pool, gym, tennis courts and sauna are also included.
Is Buchinger Wilhelmi Marbella suitable for couples?
Yes. Double rooms are available in most categories. Both guests follow their own medical plan, so one can fast while the other takes the Diet program. Couples often book the Junior Suite or a Penthouse for more space.
How does Buchinger Wilhelmi Marbella compare to the Lake Constance clinic?
Both clinics follow the same Buchinger fasting method and offer identical program structures. The main difference is setting and climate. Marbella offers a Mediterranean environment with year-round warm weather. The Lake Constance clinic in Ueberlingen sits on the German-Swiss border with Alpine scenery. Marbella has 101 rooms; Ueberlingen is larger.
What does a stay at Buchinger Wilhelmi Marbella cost?
Prices start from around 4,270 euros for the 10-night Compact package in a Standard room. The 28-night Classic Royal begins at approximately 10,780 euros. Room upgrades, specialist treatments and beauty services are charged separately. Contact the clinic directly for a personalised quote.
