Buchinger Wilhelmi is a residential medical fasting program, not a diagnostic longevity checkup. It operates in Überlingen and Marbella and recommends at least ten days for therapeutic fasting. The 2026 Marbella price list starts Fast Compact at €4,720 for ten nights in a standard single room, with medical consultations, nursing, core laboratory work and a therapy credit included.
What we checked
We checked the provider’s current program pages and, where available, independent or regulatory sources listed below. We then separated standard inclusions from optional costs and open questions. Every source carries the date we reviewed it.
The short answer
Buchinger is a serious residential fasting program with clearer medical supervision than a typical wellness retreat. The starting price is only useful once room category, stay length, specialist care, medication and treatments above the included credit are added. It is most suitable for someone specifically choosing supervised fasting, not someone shopping for a broad diagnostic workup.
At a glance
The program combines a preparation day, a fasting period and a structured return to food. The 2026 Marbella information includes accommodation, initial and final standard laboratory work, two medical consultations per seven nights, 24-hour nursing, an on-call doctor, fasting provisions, group activities and a €45-per-night therapy credit.
The published 2026 Marbella starting point is €4,720 for a ten-night Fast Compact stay in a standard single room. Price changes with clinic, room, duration and program. Specialist medicine, medication, supplements, non-fasting meals and therapies above the credit can add to the bill. Request the complete stay estimate before paying a deposit.
Buchinger says the shortest clinic fasting program needs time for preparation, roughly six fasting days and gradual refeeding. Its public guidance advises against longer unsupervised fasting and describes daily nursing checks plus medical support. That structure is the main difference from a hotel cleanse or fasting box.
Fasting can affect blood pressure, glucose, medication needs and hydration. A residential setting reduces some practical risk but does not make the program appropriate for every diagnosis, pregnancy, eating-disorder history or frail patient. Ask the medical team to review contraindications and medication changes before travel.
Buchinger provides app-based material and discharge guidance, but its public pages do not specify a fixed schedule of post-stay physician appointments. Ask what laboratory or clinical reassessment is recommended, who reviews it and how the plan connects with your doctor at home.
