What is Fasting? The Science and the Tradition

Fasting is, at its most essential, the voluntary and conscious abstention from food, or from certain categories of food and drink, for a set period of time. It is not a trend. It is not a shortcut. It is one of the oldest and most studied practices in human history, woven into the fabric of ancient medicine, spiritual tradition and, increasingly, cutting-edge cellular biology.

For centuries, physicians from Hippocrates to Paracelsus advocated periodic fasting as a means of restoring the body's natural equilibrium. Today, researchers at institutions including the University of Southern California and the Salk Institute have illuminated precisely why: when the body is relieved of the constant metabolic work of digestion, it redirects its resources towards repair, regeneration and the elimination of damaged cellular material, a process known as autophagy.

A landmark 2019 study published in the New England Journal of Medicine demonstrated that intermittent fasting triggers significant improvements in metabolic health, cognitive function and inflammatory markers, even across relatively short periods of practice. The mechanism is elegant in its simplicity. When glucose stores are depleted, the body shifts into a fat-burning state, producing ketones that serve as an alternative fuel source for the brain and organs, while simultaneously activating repair pathways that remain dormant during normal feeding cycles.

What makes a fasting retreat distinct from any clinical protocol is the environment in which this process unfolds. Surrounded by nature, supported by experienced practitioners and relieved of the friction of daily life, the body enters a state of restoration that a home-based fast can rarely replicate.

Types of Fasting: A Complete Guide

Not all fasting programmes are alike, and the right approach depends entirely on the individual: their health history, their goals and the depth of experience they are seeking. The retreats curated by Healing Holidays encompass the full spectrum of therapeutic fasting, from alkaline and Buchinger programmes rooted in European naturopathic tradition to the diagnostic rigour of Modern Mayr Medicine and the whole-body reset of colonic detox protocols.

Alkaline Fasting

Alkaline fasting works by systematically removing the excess acids, inflammatory metabolites and toxic byproducts that accumulate in the body's tissues over time. By restricting intake to alkaline-forming foods and targeted detoxification treatments, the programme neutralises acid load, rebalances the body's pH environment and removes the biochemical obstacles that suppress natural detoxification and compromise the oxygen and nutrient supply to the cells. The result is a profound internal cleanse that addresses the underlying chemistry of chronic fatigue, inflammation and metabolic stagnation at a level that conventional dietary approaches rarely reach. Alkaline fasting is exclusive to Engel Ayurpura in Italy, where the programme runs over seven nights and integrates detox treatments, personalised nutritional guidance and the restorative backdrop of the South Tyrolean mountains.

Buchinger Fasting

Developed by German physician Otto Buchinger in the early twentieth century, Buchinger fasting is one of the most respected and clinically documented forms of therapeutic fasting in existence. Guests consume small quantities of consomme, organic juices and herbal teas in place of solid food, a protocol designed to achieve the metabolic benefits of a full fast while maintaining the body's essential nutrient supply. Solid foods are consciously withheld to avoid triggering digestive enzyme production and the sensation of hunger that solid chewing provokes. The result is a state of deep physiological rest and cellular renewal that few other interventions can replicate. At Engel Ayurpura in Italy, the Buchinger Fasting programme is offered over seven nights within an alpine setting of extraordinary calm, under the guidance of specialist medical practitioners.

Modern Mayr Medicine

Rooted in the early twentieth-century discoveries of Austrian physician Dr. Franz Xaver Mayr, Modern Mayr Medicine is founded on a deceptively simple premise: the health of the entire body begins and ends with the health of the gut. The method addresses the digestive system not merely as a functional organ but as the primary site of systemic inflammation, immune dysregulation and metabolic imbalance. Guests follow a precisely calibrated elimination diet, ranging from a gentle milk and bread protocol to a more restricted semoliquid or fasting regimen depending on individual diagnostic findings, combined with manual abdominal therapy, chewing rehabilitation, targeted medical treatments and a comprehensive programme of diagnostics that may include full blood panels, bioenergetic assessment and 3D body scanning. Modern Mayr Medicine is the most widely practised method across our European fasting portfolio, offered at Lanserhof Tegernsee, Lanserhof Sylt and Lanserhof Lans in Germany and Austria, at VIVAMAYR Maria Worth, MAYRLIFE Altaussee and Park Igls in Austria, at Buff Medical Resort and at OCEANO Health Spa Hotel in Spain.

Colonic Cleanse and Detox Fasting

A colonic cleanse detox programme works from the inside out, using daily colon hydrotherapy sessions combined with a structured programme of detox meals and drinks to systematically flush the digestive tract of accumulated toxins, restore gut motility and rebalance the intestinal environment. It is a more targeted and intensive form of internal cleansing than dietary modification alone and is particularly well suited to guests with a history of digestive discomfort, bloating or sluggish elimination. Absolute Sanctuary in Thailand offers this programme over three, five or seven nights, integrating daily colon hydrotherapy with unlimited yoga and fitness classes, spa treatments and the warm hospitality of Koh Samui.

FASTING METHODS AT A GLANCE: Programmes, Duration and Where to Experience Them

Why Practice Fasting?

Long before science provided the vocabulary to explain it, human civilisations understood that periodic fasting was not deprivation. It was a form of respect, offered to the body, to the spirit, and to something larger than both.

In the Ayurvedic tradition, fasting is called Langhana, meaning to make the body light, and has been prescribed as medicine for thousands of years. In Islamic tradition, the fasting month of Ramadan disciplines both body and mind through communal abstinence. Yom Kippur, the holiest day in the Jewish calendar, is observed through a complete fast. Christian monastic orders have long integrated regular fasting days as a means of spiritual clarity and physical purification. These are not coincidences. They are different cultures arriving at the same truth through different paths.

From a physiological standpoint, the reasons are now well established. Fasting reduces circulating insulin levels, which reverses insulin resistance and allows stored body fat to become accessible as fuel. It activates autophagy, the body's cellular housekeeping mechanism, through which damaged proteins and dysfunctional cellular components are broken down and recycled. It reduces systemic inflammation, one of the primary drivers of chronic disease. It lowers blood pressure, improves lipid profiles and promotes the regeneration of immune cells.

From a psychological standpoint, the benefits are equally compelling. The act of consciously choosing not to eat, in a supported and intentional environment, cultivates a relationship with hunger that is neither anxious nor reactive. It builds a quiet form of self-sovereignty that, for many guests, proves to be among the most lasting gifts of the retreat experience.

Why Choose a Fasting Retreat Over Fasting at Home?

The honest answer is that fasting at home is possible. But it is rarely optimal, and for more intensive protocols, it carries genuine risk.

The conditions that make a fasting retreat effective are not incidental to the location. They are the product of an entire ecosystem designed to support the body through a profound physiological process. When you fast in a dedicated retreat setting, you are not simply abstaining from food in a different postcode. You are placing yourself within a structure that has been refined over decades to ensure that every element, from the quality of the broths you consume to the expertise of the physician who monitors your blood work, works in service of the same outcome.

There is also the matter of the environment itself. Chronic stress is one of the most powerful obstacles to the physiological benefits of fasting. Elevated cortisol levels can inhibit autophagy, impair fat metabolism and keep the nervous system locked in a state of alertness that prevents genuine restoration. A luxury fasting retreat removes the ambient stressors of daily life: the inbox, the commute, the domestic responsibilities. It replaces them with natural beauty, human warmth and an invitation to be present.

The Benefits of a Medically Supervised Fasting Retreat

The body's response to therapeutic fasting is not subtle. Within the first twenty-four to forty-eight hours, metabolic processes that may have been compromised for years begin to recalibrate. By the third or fourth day, most guests report a perceptible shift: a lightness, a clarity, a quieting of the internal noise that had come to seem simply like the texture of modern life.

Metabolic Reset and Sustainable Weight Loss

Fasting is among the most clinically effective interventions for reversing insulin resistance, the metabolic condition that underlies both Type 2 diabetes and persistent weight gain. In a supervised retreat environment, the fasting process is complemented by nutritional re-education, movement therapy and behavioural coaching, creating the conditions for weight loss that is not only achieved but sustained. Unlike crash dieting, therapeutic fasting addresses the hormonal and cellular roots of metabolic dysregulation.

Cellular Regeneration and Autophagy

The activation of autophagy during fasting is one of the most significant discoveries in modern biology, recognised with the Nobel Prize in Physiology or Medicine in 2016. Through this process, the body identifies and dismantles damaged, dysfunctional or potentially dangerous cellular material, recycling it into clean cellular components. The result, over the course of a sustained fasting programme, is a measurable improvement in cellular health across virtually every organ system.

Digestive Rest and Gut Health Restoration

The digestive system is among the most energetically demanding systems in the body. When it is given a sustained period of rest, the gut lining has the opportunity to repair, the microbiome begins to rebalance and the chronic low-grade inflammation that characterises many modern digestive conditions begins to subside. Many guests who arrive at fasting retreats with long-standing digestive complaints report significant and lasting improvement following their programme.

Mental Clarity and Cognitive Function

The cognitive dimension of therapeutic fasting is one that surprises many first-time guests. Far from the fogginess they might expect, many report a progressive sharpening of mental clarity from the third or fourth day of their programme, driven by the brain's efficient use of ketone bodies as a clean fuel source. Decision-making, emotional regulation and the capacity for sustained attention are all commonly reported to improve.

Immune System Strengthening

Research from the University of Southern California has demonstrated that prolonged fasting triggers the regeneration of entire populations of immune cells, effectively renewing one of the body's primary defence systems. For guests recovering from illness, navigating the effects of chronic stress or simply seeking to reinforce their baseline resilience, a therapeutic fasting programme offers a profound immunological reset.

Reduced Inflammation

Chronic systemic inflammation is now understood to be a contributing factor in conditions ranging from cardiovascular disease to depression. Therapeutic fasting consistently produces measurable reductions in key inflammatory markers, including C-reactive protein and interleukin-6, and these reductions have been shown to persist well beyond the end of the fasting period itself.

Spiritual Clarity and Emotional Renewal

The relationship between fasting and spiritual clarity is one that no biochemical marker can fully capture. Across cultures and centuries, those who have fasted describe a quality of presence, a permeability to experience, that is difficult to access in the midst of ordinary life. Many guests describe their fasting retreat as the most significant experience of their year, not because of what was achieved physically, but because of what became visible when the noise of habitual consumption was removed.

Improved Sleep Quality

The relationship between metabolic health and sleep is bidirectional. As insulin sensitivity improves and cortisol rhythms normalise during a fasting programme, sleep quality typically follows. Guests consistently report deeper, more restorative sleep from the midpoint of their programme, an effect that frequently persists as a lasting benefit.

As Dr. Andreas Michalsen, Professor of Clinical Naturopathy at the Charite University Hospital in Berlin and one of Europe's foremost authorities on therapeutic fasting, has noted: "Fasting is the most effective biological intervention we have for achieving rapid, whole-system metabolic change. The challenge has always been creating the conditions in which people can fast safely and well. That is precisely what a well-designed fasting retreat provides."

Who Is a Fasting Retreat Right For?

A fasting retreat is not the exclusive preserve of athletes or the deeply health-conscious. It is relevant to anyone who has arrived at a moment of wanting to genuinely reset, rather than simply rest. Our guests come from extraordinarily varied backgrounds and arrive with equally varied intentions.

Those who tend to derive the greatest benefit from a therapeutic fasting programme include:

• Individuals experiencing metabolic challenges, including weight plateau, insulin resistance or pre-diabetic markers
• Those suffering from chronic fatigue, low-grade inflammation or persistent digestive discomfort
• Professionals navigating burnout who recognise that rest alone will not be sufficient
• Individuals approaching midlife who wish to audit and recalibrate their baseline health
• Those seeking a structured transition away from habitual dietary patterns that no longer serve them
• Guests with a spiritual practice who wish to deepen it through intentional, supported fasting
• Those who have read the research and simply wish to experience the cellular benefits of autophagy activation for themselves

Medical Considerations and Contraindications

Therapeutic fasting is a powerful intervention and, like all powerful interventions, it is not universally appropriate. At Healing Holidays, we work exclusively with retreat partners who conduct thorough pre-programme medical assessments for every guest.

Fasting programmes are generally not recommended for those who are pregnant or breastfeeding, individuals with a history of eating disorders, those with active cancer undergoing chemotherapy, people with severe cardiac conditions or those with Type 1 diabetes. Anyone managing a chronic health condition should consult their physician prior to booking, and our wellness experts are available to advise on programme suitability before any commitment is made.

First-Time Fasters vs. Experienced Practitioners

For those new to supervised fasting, a shorter programme at Absolute Sanctuary in Thailand or Park Igls in Austria offers an excellent introduction: structured, supportive and designed to be profound without being overwhelming. More experienced guests, or those with specific therapeutic goals, will find the full diagnostic power of Lanserhof, VIVAMAYR or MAYRLIFE most appropriate to their needs.

What to Expect on a Fasting Retreat

A Typical Day at a Fasting Retreat

The texture of a day at a supervised fasting retreat is nothing like the austerity the name might conjure. It is, in fact, one of the most structured and well-attended days one can spend in a wellness context.

Morning typically begins with a gentle herbal tea or warm broth, followed by a consultation with the resident physician or wellness practitioner. A tailored movement session, ranging from a slow sunrise walk to a yoga class or aqua therapy session, precedes the mid-morning drink or light programme food. Treatments, whether manual abdominal therapy, colon hydrotherapy, acupuncture or infrared sauna, are woven through the afternoon. Evening brings meditation, a group sharing session or a lecture from one of the resident wellness experts, followed by a restorative broth and early rest.

The pace is unhurried and deeply intentional. Meals, or their equivalents, arrive at regular intervals. The body is never left without support. The mind, increasingly uncluttered, finds its own rhythm.

How Long Should a Fasting Retreat Last?

Most guests report that the pivotal shift, the moment at which the experience moves from effort to ease, occurs around the third or fourth day. Programmes of less than three nights, while beneficial, rarely allow the body sufficient time to reach the deeper metabolic states that produce the most lasting results.

How to Prepare Before You Arrive

The transition into a fasting state is smoother and more comfortable when the body has been prepared in advance. Our retreat partners recommend the following in the ten days before arrival:

• Gradually reduce caffeine intake to avoid withdrawal symptoms during the programme
• Eliminate alcohol, processed foods, refined sugar and red meat
• Increase daily water intake to at least two litres
• Begin each morning with warm water and lemon
• Reduce portion sizes progressively across the final three days
• Begin a simple mindfulness or journalling practice to prepare the mind for introspection

How to Reintegrate After Your Retreat

Post-fast reintegration is, in many ways, as important as the fast itself. The digestive system, rested and renewed, must be reintroduced to solid food gradually and thoughtfully. A well-structured retreat programme will include a dedicated reintegration phase, typically lasting one to three days on-site, beginning with raw fruits, steamed vegetables and light soups before reintroducing proteins and complex carbohydrates.

The period following a fasting retreat is also a window of unusual receptivity. The habitual patterns that previously governed eating behaviour have been interrupted, and new ones can be established with far greater ease than at any other time. Our retreats include nutritional coaching and take-home lifestyle plans to ensure that the metabolic gains of the programme are preserved and built upon.

Our Handpicked Fasting Retreats

At Healing Holidays, we do not list retreats. We curate them. Every property in our fasting portfolio has been personally assessed by our wellness experts, with particular attention to the quality of medical supervision, the expertise of the resident practitioners, the standard of the facilities and the depth of the therapeutic programmes offered.

Fasting Retreats in Germany

Germany's contribution to the world of medically supervised therapeutic fasting is rooted in a century-long tradition of naturopathic medicine, and the country's flagship properties represent its most sophisticated contemporary expression: architecturally extraordinary, diagnostically rigorous and operated by some of the most accomplished medical teams in European wellness.

• Lanserhof Tegernsee
  Germany | 7, 10 or 14 nights

Set against the Bavarian Alps on the shores of Lake Tegernsee, Lanserhof Tegernsee is one of the most architecturally distinguished medical spas in Europe and the original and most celebrated property in the Lanserhof group. Its programmes are built on the award-winning LANS Med Concept, which integrates Modern Mayr Medicine with advanced medical science and naturopathy to deeply cleanse the body of accumulated toxins and restore gut health at a cellular level. Following a thorough medical examination on arrival, the resident physician designs a fully personalised programme incorporating a tailored Mayr diet, abdominal treatments, targeted diagnostics and a carefully curated selection of supporting therapies. The Cure Classic and the enhanced Cure Classic Plus represent two levels of the same medically exacting approach, with the Plus programme incorporating additional diagnostics and a deeper therapeutic scope for guests seeking the most comprehensive reset available.

• Lanserhof Sylt
  Germany | 7, 10, 14 or 21 nights

Located on Germany's North Sea island of Sylt, this Lanserhof property applies the same rigorous LANS Med Concept as Tegernsee within a dramatically different coastal landscape: the austere beauty of the North Sea, long white beaches and the particular quality of salt-laden Atlantic air. For guests who find their deepest calm in coastal rather than alpine environments, Sylt offers an equally powerful therapeutic experience in an aesthetically distinctive setting. The Cure Classic and Cure Classic Plus programmes run from seven to twenty-one nights, providing the flexibility to design a stay that fits both schedule and therapeutic ambition.

• Buff Medical Resort
  Germany | 7, 10, 14 or 21 nights

Created by Swiss entrepreneur Hans Jurg Buff, Buff Medical Resort is a cutting-edge medical wellness destination that brings a different energy to the European fasting landscape. Its programmes are rooted in Modern Mayr Medicine and range from the entry-level BuffMed Fasting Pure, the foundational Mayr programme that includes medical examinations, a personalised Mayr diet and abdominal treatments, to the comprehensive BuffMed Classic, which adds 3D body scanning, ECGs and a wider scope of targeted therapies, and the BuffMed Advanced, which incorporates a detailed cardiovascular assessment using state-of-the-art diagnostic equipment. The BuffMed Vitality programme offers an ideal introduction for guests new to fasting, providing a guided exploration of different fasting methods, including eight-hour fasting, intermittent twenty-four-hour and seventy-two-hour fasting, within a supported and supervised environment.

Fasting Retreats in Austria

Austria is the birthplace of Modern Mayr Medicine and remains, by any measure, the world's most concentrated destination for medically supervised therapeutic fasting. The country's clinics have spent decades developing the diagnostic tools, the treatment protocols and the culinary infrastructure to make the Mayr experience as clinically effective, and as quietly luxurious, as it is possible to be.

• VIVAMAYR Maria Worth
  Austria | 7 or 14 nights

Positioned on the southern shore of Lake Worthersee in Carinthia, VIVAMAYR Maria Worth is widely regarded as the preeminent destination for Modern Mayr Medicine in the world. Its setting is among the most beautiful of any medical wellness property in the Alps: a private lakeshore with uninterrupted views of the Karawanken mountains, clean water, clean air and the particular stillness that only an alpine lake can provide. The clinic's medical team conducts an exhaustive bioenergetic and medical diagnostic assessment on arrival, designing a programme that combines a precisely calibrated Mayr elimination diet with manual abdominal therapy, infusions, targeted medical treatments and an exceptional programme of movement and mindfulness practices. The VIVAMAYR Pure Programme forms the foundation of every stay and ensures that all subsequent treatments are built on a comprehensive and accurate understanding of the individual's current state of health.

• MAYRLIFE Altaussee
   Austria | 4, 7, 10 or 14 nights

Set within the UNESCO-protected Salzkammergut lake district of Styria, MAYRLIFE Altaussee brings Modern Mayr Medicine to one of the most scenically extraordinary addresses in the Austrian Alps. The portfolio of programmes is among the most diverse of any Mayr destination, ranging from the four-night Health Potential Reset, a medically grounded short programme designed to rapidly realign metabolism and mental balance, to the flagship Classic Programme, available over seven or fourteen nights, which forms the individually tailored foundation for every longer stay. The Summer Longevity Programme offers a different kind of reset for guests seeking recovery and renewal alongside a more active alpine experience. For those with specific therapeutic targets, the Anti-Inflammatory Reset in partnership with Dr. Barbara Sturm combines MAYRLIFE's diagnostic precision with a highly personalised anti-inflammatory nutrition and skin health protocol, while the Weight Balance Reset provides a medically guided approach to understanding and addressing the underlying causes of weight imbalance. The Active Detox programme further incorporates cryotherapy and intermittent hyperoxic training for guests who wish to combine detoxification with a more dynamic physical dimension.

• Lanserhof Lans
   Austria | 7, 10, 14 or 21 nights

Situated in the Tyrolean valley above Innsbruck, Lanserhof Lans is an architecturally remarkable property and the Austrian flagship of the Lanserhof group. Like its German counterparts, it operates on the LANS Med Concept, combining Modern Mayr Medicine with advanced naturopathy and the latest clinical science. The Cure Classic and the enhanced Cure Classic Plus programmes are available from seven to twenty-one nights, offering guests the flexibility to calibrate the depth of their experience to their available time. Lanserhof Lans has also developed a specialist Long Covid Advanced programme for guests still managing the physiological consequences of post-viral illness, reflecting the breadth of the group's clinical capability.

• Park Igls
   Austria | 4, 7, 14 or 21 nights

Located a short distance from Innsbruck, circled by the Tyrolean Alps and operating as a dedicated Mayr medical clinic since 1976, Park Igls carries one of the longest and most quietly distinguished reputations in European therapeutic fasting. It is smaller and more intimate in scale than the Lanserhof properties, with an atmosphere that leans more towards clinical focus than resort luxury, and it is precisely this character that makes it the preferred address for guests who come primarily for the rigour of the medicine rather than the grandeur of the surroundings. The Mayr Short Break Programme over four nights offers an accessible introduction to the method. The Detox Classic Programme, available over seven, fourteen or twenty-one nights, is the most comprehensive offering, including medical examinations, a personalised Mayr diet, daily Kneipp treatments and full body massages in a programme that has been refined through decades of consistent clinical practice.

Fasting Retreats in Italy

Italy brings to the world of therapeutic fasting its own particular sensibility: the belief that beauty, precision and pleasure are not obstacles to healing but essential conditions of it. Engel Ayurpura, set in the South Tyrolean mountains, is the sole Italian property in our fasting portfolio and one of the most distinctive.

• Engel Ayurpura
   Italy | 7 nights

Nestled within the alpine landscape of South Tyrol, Engel Ayurpura offers two programmes that are exclusive to Healing Holidays and represent some of the most singular fasting experiences available in our portfolio.

The Alkaline Fasting programme addresses the body's acid overload through a combination of alkaline-forming nutrition, targeted detox and cleansing treatments and carefully prescribed supplementation. By removing excess acids and inflammatory metabolites from the tissues and restoring the body's pH balance, the programme eliminates the biochemical obstacles that impair cellular function, immune response and natural detoxification. It is a particularly well-suited programme for guests experiencing chronic fatigue, persistent joint discomfort, skin conditions or the systemic effects of long-term dietary imbalance.

The Buchinger Fasting programme follows the modified long-term fasting protocol developed by Dr. Otto Buchinger, restricting intake to consomme, organic juices and herbal teas. The deliberate omission of solid food prevents the digestive system from producing the enzymes and hormonal responses that accompany eating, allowing the body to enter a state of profound metabolic rest and cellular repair. Both programmes run over seven nights and are supported by Engel Ayurpura's resident medical and wellness team within the peaceful, mountain-edged setting that makes this property an experience genuinely apart.

Fasting Retreats in Spain

• OCEANO Health Spa Hotel
   Tenerife, Spain | 10 or 14 nights

Positioned on the dramatic volcanic coastline of Tenerife, OCEANO Health Spa Hotel is a dedicated F.X. Mayr centre offering a focused and clinically serious range of Modern Mayr Medicine programmes. The Oceano Mayr Classic forms the foundation: fourteen nights of medical examinations, personalised Mayr diet and colon hydrotherapy that address the root causes of digestive dysfunction and metabolic imbalance with uncommon directness. The Mayr Detox programme adds a layer of holistic detox treatments for those who wish to combine the Mayr cure with a broader cleansing approach, while the Mayr Active programme integrates personal training and aqua bike sessions for guests seeking a physical performance dimension alongside their therapeutic fasting. The Mayr Mental Balance programme is the most distinctive offering, combining the core Mayr protocol with targeted therapies for stress reduction and emotional equilibrium, making it particularly relevant for guests whose primary motivation is burnout recovery and nervous system restoration. The combination of the Canary Islands' exceptional winter light, year-round warmth and the Spanish Atlantic coastline makes OCEANO a particularly compelling destination for European guests seeking a fasting retreat in the colder months.

Fasting Retreats in Thailand

Thailand's wellness culture brings to the therapeutic fasting experience a quality of care and an attentiveness to the guest's complete comfort that is genuinely distinctive. Absolute Sanctuary on Koh Samui is our recommended Thai destination for guests seeking a shorter, accessible and excellent-value introduction to the fasting and detox retreat experience.

• Absolute Sanctuary
   Koh Samui, Thailand | 3, 5 or 7 nights

For guests seeking a fasting and detox retreat that combines clinical effectiveness with the warmth and accessibility of Thai hospitality, Absolute Sanctuary on the island of Koh Samui is an exceptional address. The Colonic Cleanse Detox Programme is designed for guests with some prior experience of detoxing and works from the inside out: daily colon hydrotherapy sessions, combined with a structured programme of detox meals and drinks, systematically cleanse the digestive tract, restore gut motility and remove the accumulated toxins that compromise energy, digestion and immune function. Available over three, five or seven nights, the programme is complemented by unlimited access to the property's yoga and fitness class schedule and a range of spa treatments, creating a complete reset of body and mind at an accessible price point. Absolute Sanctuary is also one of the most well-regarded yoga and fitness destinations in Asia, and for guests who wish to combine their detox programme with an intensive movement practice, it represents a genuinely compelling combination.

What Our Guests Say 

"I left feeling completely transformed, as if the clock had been turned back. I have new levels of energy I don't think I have experienced in years. I'm determined to carry on with as much of the programme as possible to sustain these incredible results."
Michelle, Lanserhof Tegernsee

"The programme is tough but transformational. It prompts a real change in habits and lifestyle."
Laurence, MAYRLIFE Altaussee

"Lanserhof Lans is a very serious clinic. It's the perfect place if you're looking to truly make a difference. After my visit I felt lighter, calmer, I had lost five pounds and had a new understanding of the importance of taking time for myself to recharge. Even my husband noticed a change, so much so he's now booked in for a week himself."
Trudy, Lanserhof Lans

"I have abandoned medication as MAYRLIFE Altaussee gave me the confidence to believe I could do it myself and for my health I just must persevere."
Marcia, MAYRLIFE Altaussee

"I had a very in-depth consultation with Frances, who asked lots of questions about my health and ultimately what I wanted to achieve from my wellness break. She had been to Lanserhof herself and felt that this was the place for me. She told me which doctor would suit me, what treatments would help me, and her top tips for getting through a week there. I have to say she was spot on. Healing Holidays are certainly much more than a travel agent. They are a real specialist."
Alice, Lanserhof Tegernsee

"It was a life-changer. I have never experienced such a nurturing environment. The food, staff attentiveness, accommodation and of course the medical attention were all exceptional. I couldn't recommend it enough."
Karen, MAYRLIFE Altaussee

"The retreat and all of its treatments and sessions were exactly what I wanted. The food was delicious and healthy. The fitness sessions, including the personal training, Pilates reformer and yoga were challenging and fun and all of the treatments were out of this world. I couldn't have asked for a more perfect break."
Lydia, Absolute Sanctuary

"After the first three days I really felt re-energised and re-vitalised. I was super impressed with the thorough medical check-up and felt well cared for throughout my stay. My whole stay was nurturing."
Verity, Park Igls

"I went a little sceptical, but after completing the retreat I am a firm believer in the LANS Med Concept. Thanks to the advice of the doctors I know how to sustain the results. You really get to learn so much about yourself here."
Julie, Lanserhof Tegernsee

"An amazing place to go for solo travellers. There is great interaction between guests, the food was amazing, and there is a wonderful vibe. I would definitely return, and will always use Healing Holidays. They know their stuff."
Lynne, Absolute Sanctuary

Frequently Asked Questions About Fasting Retreats

What is a fasting retreat?

A fasting retreat is a structured wellness programme, typically residential, in which guests voluntarily restrict food intake under medical or professional supervision for a defined period. Programmes vary significantly in type and intensity, from alkaline fasting and Buchinger protocols at Engel Ayurpura in Italy to Modern Mayr Medicine programmes across Austria and Germany and colonic cleanse detox at Absolute Sanctuary in Thailand, and are complemented by a range of supporting therapies including yoga, massage, hydrotherapy and mindfulness practices.

Is fasting safe for everyone?

Therapeutic fasting, when properly supervised, is safe for the vast majority of healthy adults. It is not recommended for pregnant or breastfeeding women, individuals with a history of eating disorders, those with certain cardiac conditions, people with Type 1 diabetes or those undergoing active cancer treatment. All of our retreat partners conduct a thorough medical assessment prior to programme commencement. If you are uncertain whether a fasting programme is appropriate for you, our wellness experts are available for a confidential pre-booking consultation.

What is the difference between Buchinger, Alkaline and Mayr fasting?

These are three distinct therapeutic fasting approaches, each addressing the body's health through a different mechanism. Buchinger fasting achieves cellular rest and repair through a liquid-only protocol of consomme, organic juices and herbal teas, eliminating solid food to prevent digestive activation. Alkaline fasting targets the body's acid-base balance, using alkaline-forming nutrition and detox treatments to neutralise acid overload, reduce inflammation and restore the biochemical environment in which the body's natural detoxification can function optimally. Modern Mayr Medicine centres on the rehabilitation of the digestive system as the root of whole-body health, using a precisely calibrated elimination diet, manual abdominal therapy and comprehensive diagnostics to restore gut function and systemic metabolic balance. All three are medically supervised and deeply effective. The right choice depends entirely on individual health history, objectives and temperament, and our wellness experts are well placed to advise.

What is the difference between a fasting retreat and a detox retreat?

The terms are sometimes used interchangeably, but they describe meaningfully different experiences. A detox retreat focuses on cleansing the body of accumulated toxins through dietary modification, supplementation and supportive therapies, but does not necessarily involve significant caloric restriction. A fasting retreat involves a meaningful reduction or elimination of solid food intake, which triggers specific metabolic responses, including autophagy activation and ketosis, that a standard detox programme does not necessarily achieve. The colonic cleanse detox at Absolute Sanctuary, for instance, works primarily through the digestive tract, while the Mayr and Buchinger programmes at our European properties address metabolism and cellular health at a systemic level.

How long should a fasting retreat last?

For first-time guests, a programme of four to seven nights is generally recommended. The four-night Mayr Short Break at Park Igls and the three to seven night Colonic Cleanse at Absolute Sanctuary represent excellent starting points. Guests with specific therapeutic goals, or those returning to the practice, typically derive the greatest benefit from programmes of ten to fourteen nights, while the most profound cellular and metabolic outcomes are associated with programmes of twenty-one nights at destinations such as Lanserhof, MAYRLIFE or Park Igls.

What can I eat on a fasting retreat?

This depends on the type of programme. Buchinger fasting involves consomme, organic juices and herbal teas. Modern Mayr Medicine programmes follow a precisely calibrated elimination diet that typically progresses from a milk and bread protocol to semoliquid or fasting phases depending on individual diagnostic findings. Alkaline fasting involves alkaline-forming foods and detox drinks selected to neutralise acid load. The Colonic Cleanse Detox at Absolute Sanctuary includes structured detox meals and drinks. In every case, what is consumed is carefully selected by the programme's medical or wellness team and calibrated to the individual's specific needs and goals.

How much does a fasting retreat cost?

Our fasting retreat portfolio ranges from approximately 869 GBP per person for a three-night Colonic Cleanse Detox at Absolute Sanctuary in Thailand to over 16,000 GBP per person for the comprehensive BuffMed Advanced programme at Buff Medical Resort. The majority of our European Mayr and Buchinger programmes are positioned between 2,000 and 9,000 GBP per person for a seven to fourteen night stay, reflecting the quality of medical supervision, the expertise of the resident teams and the diagnostic depth of the programmes offered. Our wellness experts are able to identify programmes that align with both your therapeutic objectives and your budget.

Can I exercise during a fasting retreat?

Yes, and movement is actively encouraged as part of most fasting programmes, though the nature and intensity of exercise is carefully calibrated to the programme and the individual's energy levels. Gentle practices such as yoga, Pilates, aqua therapy, guided walking and Kneipp treatments are typically integrated into the daily schedule. The BuffMed Vitality programme at Buff Medical Resort and the Mayr Active programme at OCEANO specifically incorporate structured fitness sessions alongside the therapeutic fasting protocol. High-intensity exercise is generally avoided during the first days of any fasting programme, as the body's energy resources are being redirected towards repair and regeneration.

What should I do to prepare for a fasting retreat?

Preparation significantly improves both the comfort and the effectiveness of any fasting programme. In the ten days before arrival, we recommend gradually eliminating caffeine, alcohol, refined sugar, processed foods and red meat from your diet. Increase daily water intake, reduce portion sizes progressively in the final days, and begin a simple mindfulness practice to prepare the mind for the introspective dimension of the experience. Your retreat's medical team will provide a detailed pre-programme protocol specific to your chosen programme upon booking.

Finding the right fasting retreat requires more than a search engine.

We invite you to speak with one of them.
