Lanserhof has spent four decades persuading wealthy people to chew their bread 30 times and eat soup for supper. At Tegernsee it now adds something more modern on top: a Longevity package with telomere measurement, “Hallmarks of Aging” lab tests, heart rate variability and a cold chamber. We looked at what those tests can and cannot tell you, and what the week costs once the room is added.
The question: what would I do if someone told me my cells were older than I am?
I find the idea of measuring biological age fascinating. It’s tempting to imagine having a blood test that tells you how well you’re aging, perhaps even before you notice anything wrong.
Lanserhof offers some interesting diagnostics, including telomere measurements and other longevity-related tests.
But what happens if the result isn’t particularly good?
Imagine being told that your telomeres are shorter than expected. Would that mean I’m getting older faster? Could I actually do something about it? And if the answer is to exercise more, improve my diet and sleep properly, did I really need an expensive test to tell me that?
I’m interested in the science, particularly which measurements are useful for making medical decisions and which are still mostly research tools.
DailyStoke has not stayed at Lanserhof Tegernsee, so this is a research-led review based on Lanserhof’s program and price documents, published research and independent reporting, checked in October 2026.
Verdict: Lanserhof Tegernsee is one of the most medically serious retreats in Europe, and its core offer, a supervised Mayr-style diet, routine lab work, gut treatments and daily movement, is coherent and well staffed. The Longevity add-on is the weaker buy. A telomere result cannot guide treatment for an individual, and the most predictive measure of healthy aging, a proper fitness test, is not on the package list. Pay for the medical week; treat the longevity tests as curiosity.

What Lanserhof is built on
Lanserhof grew out of the work of the Austrian physician F.X. Mayr, whose cure treats the gut as the center of health and prescribes rest for digestion. In practice that has meant small, plain meals eaten slowly, herbal teas between rather than with meals, abdominal massage and a lot of early nights. A 2019 account in The Week described a 700 to 800 calorie menu of milk or yogurt with measured dietary bread, chewed 30 to 40 times a mouthful, and vegetable soup in the evening. Lanserhof now tailors the food more, from supervised fasting to fuller meals, but the logic remains.
The group calls Tegernsee “Europe’s most modern health resort” and advertises a “World’s Best Medical Spa 2025” award. It has also grown: in October 2025, a consortium led by King Street Capital Management and the investor Manuel Puig put €95 million into the business, with existing shareholders keeping a majority, according to Spa Business.
What the Longevity package includes
According to Lanserhof’s package page, the add-on contains 13 items across six medical fields:
- Lab work: an overall lab test, telomere measurement, a nutrient analysis, a stool analysis including Helicobacter and “longevity lab tests (Hallmarks of Aging, depending on scope)”
- Measurements: a metabolic measurement and an HRV (heart rate variability) measurement with evaluation and discussion
- Treatment: one infusion, “according to individual indication and medical prescription”
- Movement and performance: cold chamber or simulated altitude training, a 25-minute movement consultation and a 50-minute sports training session
- Follow-up: a 20-minute medical phone call after the stay and a 50-minute nutrition session (without a nutrition plan)
The base Therapy Classic supplies the rest: medical examinations, check-ups, detox drainage, lymph and foot treatments, bioimpedance body analysis, a hay liver wrap, urinalysis, group movement and relaxation, lectures and a 24-hour on-call doctor. A UK agent’s listing of the combined week adds manual abdominal treatments, massages and reflexology.
The telomere test: what a result actually means
Telomeres are the protective caps on the ends of chromosomes. They shorten as cells divide, and in large populations shorter average telomere length is linked to age and some age-related diseases. That is the appeal. The problems start when you try to read one person’s number.
The first is measurement. In an international study in which ten laboratories measured the same blinded DNA samples, results varied by a median of about 24 percent between labs, and by more than 20 percent for the common qPCR method. The authors concluded that shared reference ranges were not yet feasible and that an individual result means little unless it is compared with reference values from the same lab and protocol (Martin-Ruiz et al., International Journal of Epidemiology, 2015).
The second is direction. “Longer is better” is too simple. A Mendelian randomization study of genetic variants that set telomere length found that genetically longer telomeres were linked to a lower risk of coronary heart disease but a higher risk of several cancers, including glioma and lung adenocarcinoma (Haycock et al., JAMA Oncology, 2017).
The third is the one in the question that opens this review. If your telomeres are “short,” there is no telomere-specific treatment a doctor would prescribe. The advice is exercise, diet, sleep and not smoking, which is the advice you would get anyway. Our rating: insufficient evidence (for individual decisions).
The same caution applies to the “Hallmarks of Aging” panel. The hallmarks are a research framework for how aging works, not a validated clinical test, and Lanserhof does not publish which markers it measures. Our guide to longevity clinic tests and which biomarkers are useful covers epigenetic clocks and other biological-age scores in more detail.
The other tests, ranked by whether they change care
| Test or treatment | What it can tell you | Does it change decisions? | Our rating |
|---|---|---|---|
| Routine bloods, urinalysis, medical exam | Cholesterol, glucose, kidney and liver function, blood count | Often, if something is off | Established for a defined indication |
| Stool test for Helicobacter | Infection linked to ulcers and stomach cancer | Yes, if positive and you have symptoms or risk | Established for a defined indication |
| Nutrient analysis | Deficiencies such as iron, B12, vitamin D | Yes, when a deficiency is found | Established for a defined indication |
| Broader stool and microbiome analysis | Bacterial composition | Rarely; experts advise against routine use (Porcari et al. consensus, Lancet Gastroenterology & Hepatology, 2025) | Insufficient evidence |
| Telomere length | Population-level aging signal | No | Insufficient evidence |
| “Hallmarks of Aging” panel | Undisclosed research markers | Unclear | Insufficient evidence |
| Metabolic measurement | Resting energy use, fuel mix | Can help set calorie targets for a weight program | Plausible mechanism, uncertain benefit |
| HRV measurement | Autonomic balance, stress and recovery | Rarely on its own | Plausible mechanism, uncertain benefit |
| Infusion | Depends entirely on what is in it | Yes, if it treats a diagnosed deficiency | Established for a defined indication (diagnosed deficiency only) |
| Cold chamber | Short-term cold exposure | No | Subjective wellness benefit; insufficient evidence for recovery (Costello et al., Cochrane, 2015) |
| Simulated altitude training | Training stimulus in low oxygen | No longevity data | Insufficient evidence |
Two observations stand out. First, the most useful tests on the list, routine bloods, Helicobacter and nutrient levels, are the least glamorous and could be ordered by a family doctor for a fraction of the price. Second, the package measures HRV, which wearables now estimate every night, but does not list a VO2 max test. That matters, because cardiorespiratory fitness is one of the strongest predictors of how long people live: in a cohort of 122,007 adults, higher fitness tracked with lower mortality, with no upper limit (Mandsager et al., JAMA Network Open, 2018). Lanserhof offers sports performance diagnostics elsewhere on its menu; we would ask for a fitness test before paying for telomeres.

Fasting, Mayr and the “detox” language
The core of a Lanserhof week is still dietary. Short-term calorie restriction lowers weight and blood sugar while it lasts: in a seven-day trial of Chenot’s 850-calorie diet, weight fell by about 2.5 kg and fasting glucose by about 10 percent, with no follow-up afterward (Sarmad et al., Clinical Nutrition, 2025). A structured week can be a useful reset for people who need one; it is not evidence of longer life. What it does not do is “detoxify” in any measurable sense: the US National Center for Complementary and Integrative Health says studies of detox programs are few and of low quality and that there are no studies of their long-term effects (NCCIH, updated March 2025). Treatments called detox drainages, lymph packs and foot baths are best judged as what they feel like: relaxing.
The physiology of low-calorie weeks, and what autophagy research does and does not show in humans, is in our explainer on the Chenot Method and autophagy.
Restrictive fasting is not for everyone. People who are pregnant or breastfeeding, have type 1 diabetes or take medication for diabetes or blood pressure, have a history of eating disorders, are underweight or have kidney, liver or heart disease should speak to their own doctor first. Lanserhof’s doctors screen on arrival, but they are not a substitute for the doctor who knows your history.
What a week at Lanserhof Tegernsee costs
Lanserhof bills the clinic and the hotel separately, so headline prices need adding up.
| Item | Price (per person) | Source, date |
|---|---|---|
| Longevity package, 7 nights | from €8,053 | Lanserhof package page, October 2026 |
| Longevity package, 12 to 16 nights | from €10,384 | Lanserhof package page, October 2026 |
| Therapy Classic alone, 7 to 8 nights | from €2,913 | Lanserhof price list, 2025 |
| Double Room, one person | from €755 a night (basic view) | Lanserhof price list, 2025 |
| Double Room, two people | from €1,105 a night | Lanserhof price list, 2025 |
| Agent package, 7 nights with room, full board, transfers | from £10,789 sharing, £12,349 single | Healing Holidays, Oct to Dec 2026 |
Lanserhof’s package page does not make clear whether the €8,053 already includes the Therapy Classic, so ask for a written quote. If it does, one person in the entry Double Room for seven nights pays around €8,053 for the medical program plus about €5,285 for the room, or roughly €13,300 before supplements, medication, extra treatments and transfers. The price list states that supplements and medications are extra and that unused treatments are not refunded. Cancelling less than four weeks before arrival costs 50 percent of the room rate.
What we liked, and what we did not
The medical structure is the strength: examinations at the start and end, a 24-hour doctor, routine lab work that can find real problems, and a phone follow-up after you leave. The program is honest about the time it takes, with a seven-night minimum and doctors recommending longer.
The weak points are the gap between the longevity marketing (“precision diagnostics to slow biological ageing,” in Lanserhof’s words) and what telomere and undisclosed “hallmark” tests can support, the absence of a fitness test in a longevity package, and pricing that needs a spreadsheet.
Lanserhof vs SHA, Chenot and Clinique La Prairie
SHA in Spain is warmer, more resort-like and heavier on elective technology such as IV drips and hypoxia. Chenot Palace Weggis runs a stricter, fixed 850-calorie diet with more hydrotherapy. Clinique La Prairie costs more and focuses on medical consultations and its own proprietary extract. Lanserhof sits closest to a German clinic in tone. All of them are compared in our guide to longevity retreats in Europe.
Who Lanserhof Tegernsee suits
It suits someone who wants a disciplined, medically supervised week to reset eating habits, with doctors who will look at real lab results. It suits less well someone hoping a telomere number will reveal how fast they are aging. If that is the main draw, you can learn more for less from a good GP, a fitness test and an honest look at your sleep and diet, a comparison we make in detail in are longevity retreats worth it?
Lanserhof in 2027: New Investors, a Spanish Resort and a Longevity Add-On
In 2027 Lanserhof is no longer a purely family-financed business. The €95 million investment led by King Street Capital Management and Manuel Puig in October 2025 gave institutional partners a minority stake, while the founding shareholders kept control. The group is building its first Spanish resort, at Finca Cortesín near Marbella. At Tegernsee the longevity offer is sold as a defined add-on to the classic medical program, with telomere testing, laboratory “hallmarks of aging” panels, HRV measurement and a cold chamber or altitude session, from seven nights. The underlying Mayr-inspired medical week remains the foundation that every guest books first.
Lanserhof Tegernsee: your questions answered
How much does Lanserhof Tegernsee cost?
The Longevity package starts at €8,053 per person for seven nights, booked with the Therapy Classic. Rooms are charged separately; Lanserhof’s 2025 price list starts at €755 a night for one person. A UK agent quotes seven nights from £10,789 per person sharing, including room, full board and transfers.
Is a telomere test worth doing?
As a personal health guide, not really. Results vary considerably between laboratories, longer is not uniformly better, and a short result leads to the same advice as a normal one: exercise, eat well, sleep and do not smoke.
What do you eat at Lanserhof?
A Mayr-inspired diet built around easy digestion: small portions, slow chewing, herbal teas between meals and early, light dinners. Lanserhof tailors the plan from supervised fasting to fuller meals depending on the guest.
What is the minimum stay at Lanserhof Tegernsee?
Seven nights. Lanserhof’s doctors recommend 10 to 14 nights for fasting programs, and the Longevity package can be booked for 7 to 16 nights.
