Healing from Long Covid with water fasting

Contents: Introduction, Background, Case A, Case B, Discussion, Conclusions


The term ‘Long Covid’ (also known as post-acute Covid-19 syndrome) describes the chronic symptoms which linger or develop at least a month after having first contracted the SARS-CoV-2 virus.

Since late 2020, I have been approached by a slow but steady stream of clients who have been unable to shake off Long Covid. There are several reasons for this. Since the beginning of the pandemic, many doctors have been too overwhelmed treating acute Covid to have the extra time to manage patients’ subsequent symptoms. Beyond this, medical science is simply stumped about how to deal with Long Covid: a problem which also applies to so many other chronic illnesses. Given that the individual symptoms of Long Covid usually vary quite widely, it seems to me that the typical approach of Western medicine in targeting an illness with a single drug or (set of drugs) is doomed to failure.

Water fasting avoids this whole problem by boosting the entire immune system, so that the body can return to full health under its own steam. In fact, this approach has proven to be highly effective, with an extended water fast having fully healed 75% of the clients I’ve worked with so far.

The aim of this article is to provide two case reports which illustrate how this process typically takes place. I also hope it inspires anyone suffering from Long Covid to do the same, and use an extended water fast to empower the body to make a full recovery.


The scale of Long Covid is only beginning to be appreciated. The Office of National Statistics (UK) estimates that 22.1% of all people continue to experience symptoms five weeks after first contracting the virus.[i] Of those hospitalised, various surveys estimate that 50% to 80% continue to experience symptoms three months after the onset of Covid-19.[ii] Even less well understood are the psychological ramifications of Covid. A recent study in the Lancet estimates that 33.6% of those with a previous Covid infection went on to develop or have a relapse of a psychological or neurological condition in the following six months.[iii] In terms of total figures, approximately 1.1 million people are currently estimated to suffer from Long Covid in the UK alone: that is, 1.7% of the entire population (April, 2021).[iv] In a country the size of the US, this would translate into nearly 6 million people.

Clearly, Long Covid is a huge problem which isn’t going to go away any time soon. Many people are suffering silently, with no idea how they can return to normal life. As illustrated by the two cases below, an extended water fast is effective in healing Long Covid regardless of how long the symptoms have persisted. Case A concerns a client who had contracted Covid just over a month before we met, whereas Case B concerns a client who had been suffering from Long Covid for nearly a year.



Client A, a 38-year-old female, contracted Covid-19 in December 2020: one month prior to the fast. During the acute phase of her illness, symptoms presented for 11 days and included:
Persistent rattling cough, dyspnoea (esp. tightness in the chest), hypoxia (resting blood oxygen saturation 93%), fever (38.5+C/101.5+F), elevated BP (153/90), headache, nausea, diarrhea.

After her initial recovery, Client A continued to experience:
Dyspnoea, hypoxia and elevated BP upon movement, chronic exhaustion, thickened blood, fatty liver.

Client A’s health had not been ideal before contracting Covid, and she had been diagnosed with high insulin levels (fasting mlU/I: 25) and 50% body-fat content. Given the severity of her Covid symptoms (both acute and post-acute) and the time elapsed since first contracting Covid, as well as her prior health issues and the need to address pre-diabetes, we decided the best course of action would be to undertake a 21-day water fast with possible periods of dry fasting inserted into the 21 days. (Please see the ‘Discussion’ section below for an explanation regarding why periods of dry fasting were considered.)

The fast:

This was Client A’s first zero-calorie fast. However, her prior history with alternative day fasting (ADF) provided both an element of psychological security as well as physical experience in activating a strong degree of ketosis. This permitted a smooth start to the fast, with only a minimal loss of energy and no detox symptoms over the first 3 days.

Day 4 of the fast: Client A’s Covid symptoms returned, including:
Cough, tightness in the chest, elevated BP and anxiety.

This was accompanied by more general detox symptoms, including:
Elevated heartrate and a lower back ache.

Day 5: these symptoms disappeared.

Day 7 (which we had originally identified as the likely first dry fasting period): Client A expressed that she was uncomfortable with the idea. We decided to pursue a water-only fast.

Day 9: Client A’s Covid symptoms returned again, but less intensely than on Day 4. She also experienced low energy levels and was feeling depressed.

Day 10: Client A’s Covid symptoms disappeared, but her urine had turned darkish and brown, likely due to increased levels of cleansing and possible dehydration. We increased hydration.

Day 11: Client A experienced nausea and weakness. Because of the need to continue her job, we decided to temporarily follow a low-calorie juicing protocol (250 kcal/day) in order to decrease the rate of cleansing, thereby managing detox symptoms.

Day 15: all detox symptoms had disappeared, and Client A returned to a water-only fast.

Day 17: Client A ended the fast earlier than planned because of an unexpected business trip.


From Day 10 of her fast, Client A experienced no further Covid symptoms. She also remained symptom-free through the weeklong refeeding period, after which we finished our work together. Two months later, I contacted her to discuss the final results. She reported that:

‘I am doing very well and my post Covid symptoms are gone… After the fast my insulin went down to 12 (mlU/I), my blood was normal, my cough was gone and my suffocation (sic.) disappeared. My energy went up and I’m actually feeling better than before Covid.’



Client B, a 28 year-old male, contracted Covid-19 in March 2020: 11 months prior to the fast. During the acute phase of his illness, symptoms presented for 2-4 weeks, and included:
Extreme fatigue (getting out of bed a challenge), brain fog, sore throat, anxiety and depression, chest pain, dyspnoea (esp. tightness in the chest)

Although the fatigue, brain fog and sore throat all disappeared within four weeks, the other symptoms had continued intermittently for the following 11 months. Despite repeated visits to his doctor, he was told that there was ‘nothing wrong’.

Before contracting Covid-19, Client B had been completely healthy and fit. Given his previous good state of health and the length of time he had been suffering from Long Covid, as well as the fact that Client B already had some experience in water fasting (a 10-day fast), we decided the best course of action would be to undertake a 28-day water-only fast with periods of dry fasting inserted into the 28 days. (Please see the ‘Discussion’ section below for an explanation regarding why periods of dry fasting were applied.)

The fast:

Days 1-5: the fast began smoothly, with no detox symptoms

Day 6: Client B’s acute Covid symptoms returned: tightness in the chest and low energy. These symptoms continued to present intermittently through Days 7 and 8.

Day 9: all the Covid symptoms of Days 6-8 cleared.

Day 10: Client B undertook his first period of dry fasting (36 hours).

Days 15-16: Client B undertook a second period of dry fasting (60 hours). Towards the end of the first 24 hours his Covid symptoms returned, including tightness in the lungs and a sore throat, the quality of which was closely reminiscent of that experienced during the acute phase of his illness. Around the 48-hour mark, the tightness in his lungs worsened.

Day 17: the symptoms which had appeared during the dry fast (Days 15-16) disappeared.

Days 22-25: Client B undertook a third period of dry fasting (84 hours). His Covid symptoms reappeared intermittently throughout this dry fast from approximately the 36-hour mark.

Days 26-28: The remainder of the fast passed smoothly.


On Day 2 of refeeding, Client B reported a feeling of inflammation inside the chest which lasted 48 hours. After this point, he remained completely symptom-free through his 10-day refeeding period, after which we finished our work together. Two months later, I contacted Client B to discuss the final results of his 28-day fast. He reported that:

‘The only time I ever feel chest symptoms is when I do vigorous exercise and I’m pushing myself to the limit while running. Even when I do, it’s minor. Nothing compared to what it once was and mild enough that I don’t really think much about it. I also didn’t realize how much Covid had affected me mentally. It’s like I’m back to my old way of thinking without the depression/anxiety.’


In my experience, Client A presents a typical example of how water fasting can heal post-acute Covid symptoms. In such cases, the fast usually calls forth one or more healing crises, in which the original symptoms of acute Covid return for 12-48 hours. When multiple healing crises occur during the fast, they are usually separated by a period of between several days and about a week. The first crisis is often but not necessarily the most intense. Client A’s healing crises on Days 4 and 9 fit this pattern well. (Given the time required to enter deeper ketosis and strengthen a response from the immune system, it is unlikely for the body to elicit a healing crisis before Day 4.) In my experience, it is also possible for a water fast to heal Long Covid without the client experiencing any healing crisis at all. Simply, the Covid symptoms never return post-fast, and energy levels return to normal through the course of refeeding.

The decision to include periods of dry fasting as part of both Client A and B’s fasting protocol was driven by my experience supervising fasts to heal from illness caused by other viruses, such as HSV (herpes). In such cases, a clear correlation exists between the periods of dry fasting and the onset of healing crises, thus suggesting that dry fasting accelerates and strengthens the healing process.

Client B illustrates a typical example of this. The appearance of Covid symptoms on Days 6-8 of the water fast meant that we put off Client B’s first dry fast (originally planned for the end of the first week of fasting) until Day 10. Given the proximity of the end of the first healing crisis and the beginning of this first dry fast, as well as the fact that the dry fast was planned and executed for only 36 hours, it came as no surprise that this dry fast passed uneventfully without a healing crisis. However, it should be noted that Client B’s two further healing crises did coincide with periods of dry fasting. In both cases, his acute Covid symptoms presented between 24 and 36 hours after the beginning of each dry fast. This also correlates with the period when the benefits of dry fasting are usually first felt.

It is worth mentioning Client B’s symptoms of inflammation on Day 2 of the refeeding process. It is hard to ascertain whether this constituted another healing crisis or whether it occurred as a consequence of refeeding. Certainly, the healing after a 28-day fast continues for a week or two after the actual end of the fast, and it is possible that Client B’s immune system elicited a further healing crisis at this point. The timing of this would also match the pattern of earlier healing crises, in this case occurring approximately 7 days since the previous event (Days 23-25). It is also possible, however, that the specific symptom concerned – inflammation – presented simply as part of a body-wide inflammation which frequently accompanies the early stages of refeeding after any extended fast (due to the influx of nutrients and electrolytes).

In addition to the physical aspects of the fast, both Clients A and B experienced a change to their emotional states. For example, Client A’s healing crises elicited feelings of anxiety and depression in addition to physical symptoms. Client B noted how, since the end of his fast, he no longer felt ‘depressed/anxious’. These observations implicitly support recent data (cited aboveiii) according to which Covid impacts on both emotional and neurological as well as physical health.

Despite the success of these two cases, an extended water fast (with or without periods of dry fasting) does not always guarantee a full healing. Partial improvement is also possible. This tends to occur especially in those whose health is already compromised by underlying health conditions, or in older people whose immune system has weakened with age. Partial improvement can also occur if the fast is not long enough to address all the issues. In such cases, it may be necessary to undertake a subsequent fast to continue progress.

As with any other fast intended to address a health issue, several factors should determine the length of the fast, as well as whether periods of dry fasting should be considered. These include the age and prior health history of the client, any prior experience in water fasting, the period elapsed since originally contracting Covid, the severity of current symptoms and the length of time since current symptoms have presented.


As the world gradually comes to grip with acute Covid, the plight of literally millions suffering from Long Covid is likely to become a growing issue – as well as a continuing strain on health systems everywhere. Because of the typically multisystemic nature of this illness, the usually targeted therapies of standard Western medicine are unlikely to be fully effective. In contrast, zero-calorie water fasting offers the necessary boost to the entire immune system in order to effect systematic long-term healing, regardless of individual symptomatology.

Comforting kitchari stew with cauliflower


This stew provides a comforting and delicious way to break fasts of up to 3 days. After longer fasts, it is perfect for reintroducing grains and legumes. Consisting of primarily mung beans and rice, both of these ingredients ideally suit the refeeding process. Rice speaks for itself, while mung beans are one of the most easily digested types of legume, requiring no prior soaking.

Although traditionally kitchari consists of mung beans and rice mixed at a 1:1 ratio, I favour a greater proportion of mung beans in this recipe. This is because, after a fast, rice (and especially white rice) often has a tendency to slow down digestion. However, the fibre content of the mung beans as well as the cauliflower prevents this from happening, and in fact both aid the smooth progress of food through the GI tract. As a cruciferous vegetable, cauliflower is also always nutritionally welcome during the refeeding process.

Traditionally, kitchari is relatively solid. Preparing this recipe as a stew ensures that it becomes as digestible as possible, with each of the ingredients guaranteed to be fully hydrated. Although the initial consistency actually resembles a soup more than a stew, the rice continues to absorb fluid after the saucepan is removed from the heat. If it thickens beyond a certain point, later servings may actually require adding a little more water.

This recipe includes a few optional spices. As with all spices during the refeeding period, my advice is to use them sparingly, especially at first.

Basic ingredients:

200 g / 8 oz mung beans
150 g / 6 oz basmati rice
1 medium cauliflower
200 ml / 8 fl oz coconut milk
Fresh coriander

Optional additional ingredients:

2 tablespoons olive oil
Curry powder (up to 2 Tbsp)
Smoked paprika (up to 1 Tbsp)
Vegetable stock cube

Total calories:

1300 calories per saucepan; with added olive oil: 1550 calories

Makes 8 servings at 160 calories per bowl of soup (350ml / 12 fl.oz.); with added olive oil: 190 calories per bowl

Cooking instructions:

There are two ways to begin this recipe.

(1a) I like to start by chopping the onions and frying them in a large saucepan over a low heat for 5-10 minutes, until they begin to turn a deeper yellow. This means using about 2 tablespoons of olive oil (approximately 240 calories). If you plan to use the curry powder and smoked paprika, throw the spices into the saucepan when the onions are done, and fry for a minute or two.


(1b) If you’d prefer to avoid all oil and frying, then skip step (1a) and instead throw the onions into the saucepan along with the mung beans in step (3). Likewise, if you plan to use the curry powder and smoked paprika, add them to the saucepan at this point too.

(2) Add about 2 litres / quarts of water to the saucepan (containing the fried onions), throw in 200g mung beans and turn up the heat. If you’re using a stock cube, add this too. Once the water starts to boil, turn down to simmer for 45 minutes. In the meantime, chop the cauliflower into bite-size portions.

(3) After 45 minutes of simmering, add the cauliflower, bring back to the boil, and let simmer for a further 10 minutes.

(4) Check that the mung beans are completely soft. If so, add 150 g / 6 oz basmati rice. Bring back to the boil and let simmer for a further 10-12 minutes, until the rice is soft. There should be enough water in the saucepan in order to prevent the rice and/or mung beans sticking to the bottom of the pan, but it’s worth stirring occasionally just to make sure. In the meantime, cut or slice the fresh coriander.

(5) When the rice is ready, take off the heat, add the coconut milk and most of the fresh coriander. Mix this into the soup and let cool to serving temperature. Use the remaining coriander as a garnish once served.

Before the fast:
Once you’ve filled out the sign-up form (by clicking one of the buttons on this page), I’ll contact you in order to set up a preliminary video call. Ideally, this should be at least a week before you plan to begin your fast. That way we can talk about how best to prepare for the fast, both physically and psychologically, as well as discuss any concerns you may have (also taking into consideration any relevant medical issues, if any).

During the fast:
Once you actually begin your fast, we’ll stay in contact via daily video calls in which you can let me know how you’re doing, and I can offer suggestions to any problems you may be having: anything from detox symptoms to sleep problems to cravings for food. The simple fact is that most people do encounter difficulties while water fasting. A recent study by the National Institutes of Health (2018) showed that over 89% of people experienced some kind of adverse event during their fast, ranging from mild to severe.** Having an experienced water fasting coach can help you avoid or reduce the severity of such problems! Once things are going smoothly, I can also offer tips to help you go deeper into your fast, both emotionally and spiritually.

Diet and lifestyle coaching after your fast

The refeeding period

Full coaching for your water fast (see here) already includes coaching for the refeeding period after your fast, while you transition back to a normal diet. This normally takes about a third to a half of the length of the actual fast. (For example, after a 10-day fast the refeeding period usually lasts 3-5 days, while after a 21-day fast it is more likely to take 7-10 days.)

Stick to good habits with diet coaching!

Full coaching ends once refeeding is over, and your digestion is up and running smoothly again. For many people, though, this is precisely when the trouble of sticking to your diet starts! This is why I also offer online diet coaching for after the fast and refeeding period (please see the contact form at the bottom of this page). The main aims of diet coaching are:

  1. To help you maintain the health benefits of your fast into the long term
  2. To continue the good habits established while refeeding
  3. To establish greater accountability for what you eat

After a fast, it is notoriously difficult to stay on track and control eating habits. If, during your fast, you’ve felt deprived by not eating, it’s likely that you’ll try to compensate afterwards by seeking extra comfort in extra food. If you’ve lost a lot of weight during the fast, your body is going to try to put that weight back on again. Sometimes there’s an insatiable hunger. Sometimes there’s just an uncontrollable urge to eat, eat, eat. There are a million reasons for things going wrong: some physical (hormonal or endocrine related, eg. ghrelin levels), some emotional and psychological (such as cravings or the return of food addictions). Whatever the reason, it can be a real struggle to stay on course – especially if you’re alone.

Which diet is best after a fast?

There are and always have been countless diets out there, all claiming to be the best. This simply illustrates that there is no single ‘best’ diet for all people at all times. I am happy to support you in following whatever diet you choose to follow, so long as it is nutritionally sound. If, on the other hand, you aren’t sure what direction is right for you, my role as a diet coach includes helping you to decide.

Lifestyle coaching to support your diet

Along with maintaining healthy choices in terms of diet, the end of a fast is also a perfect time to improve lifestyle choices. I can help you initiate or fine-tune an exercise program to burn more calories, raise your metabolic rate and stay fit and healthy. I’m also happy to support you in restructuring other areas of your life, in order to help you achieve your goals.

What diet and lifestyle coaching offers you

(1) Video calls 3 times a week (WhatsApp or Skype, usually @10-15 min)
(2) Unlimited email or messaging contact for the duration of coaching (24/7)

It’s up to you to decide how long you’d like continued support through diet and lifestyle coaching. This program works on a weekly basis and can simply be renewed as need be. However, it is a good idea to commit to a certain length of time initially, in order to ensure that you stay the course.


(1) $80 per week (discount price for those who are continuing on from full coaching)
(2) $100 per week (standard price)

In order to set up diet coaching:

(A) If we’re already working together through full coaching, just let me know you’d like to continue with diet coaching after your fast, and we’ll take it from there!

(B) If you’ve not fasted with me, and would like diet coaching:

  1. Please fill out the REGISTRATION FORM below.
  2. I will reply by email (usually within 24 hrs) in order to set up a schedule for our video calls, give you a link for payment as well as my contact details.

Dry fast coaching

Why dry fast?

Dr. Tallis Barker Ph.D.

Quite simply, dry fasting is the most powerful form of cleansing and healing known to humankind. In the same way that water fasting represents a quantum leap over any form of juice fasting, so dry fasting also involves a similar increase in strength over water fasting.

In addition to providing unparalleled maintenance cleansing in everyday life, dry fasting can also be used as a modality to heal illness. Although the zero-calorie intake of water fasting allows the body’s immune system to maximize its strength, certain health issues respond best when this is combined with a zero-intake of fluids. Examples include problems involving chronic infection (eg. Herpes, other bacteria/viruses), the growth of pathological tissue (eg. fibroids, cysts, tumors), and any situation in which it is necessary to apply the body’s maximum potential for cleansing and healing.

Because of its raw power, dry fasting is NOT for everybody, and must be approached with respect and caution.

Several articles here on describe dry fasting in greater detail. A good place to start is with the article ‘Dry fasting: fact and fiction‘. Others recount my own initial experiences with dry fasting, and provide an example of what you might expect if you decide to try dry fast: Nowadays, I regularly practise dry fasts of up to five days.


Precisely because dry fasting does require a certain degree of preliminary cleansing, I offer coaching only to (1) previous clients who have either already completed at least a 7-day water fast with me and (2) new clients starting with a 36-hour dry fast.

Compared to water fast coaching, dry fast coaching provides a greater degree of support, focussed around two video calls per day for the duration of the dry fast. This is because the detox symptoms of dry fasting tend to be more intense and develop more quickly. In addition, fewer means are available for treating them, so it’s important to get on top of the situation as soon as possible.

Given the closer supervision required of dry fasting, I do not offer single consultations for dry fasts.

Price of coaching includes:

(1) Preliminary video call (WhatsApp or Skype) before the beginning of the fast (@60 min.)
(2) TWO daily check-in video calls during the dry fast, to discuss how you’re feeling (15-20 min. per day, every day except Sundays).
(3) One daily check-in video call during refeeding and (for longer dry fasts) the preliminary water fast (1-2 days).
(4) Unlimited email or text every day for the full duration of the fast and refeeding period.
(5) Access to my personal phone number in case of emergency.


Before the fast:
Once you’ve filled out the sign-up form (by clicking one of the buttons on this page), I’ll contact you in order to set up a preliminary video call. Ideally, this should be at least a week before you plan to begin your fast. We’ll talk about how to prepare, as well as discuss any questions you may have (also taking into consideration any relevant medical issues, if any).

For longer dry fasts, I’ll ask you to precede it immediately with a short water fast: 1 day of water before a 4-day dry fast and 2 days of water before a 5-day dry fast. This will help the dry fast to proceed more smoothly.

During the fast:
Once you actually begin your dry fast, we’ll stay in contact via twice-daily video calls in which you can let me know how you’re doing, and I can offer suggestions to any problems you may be having: anything from detox symptoms to sleep problems to cravings for food. I can almost guarantee that you will experience discomfort of some kind, thanks to the sheer power of the dry fast. However, it’s important to recognise that discomfort does not equal danger!

As someone who regularly practises dry fasting, I’ve experienced all these issues, and can help guide you through your own detox symptoms.

After the fast:
Given that dry fasts can’t extend as long as water fasts, the refeeding period tends to be relatively straightforward – so long as you do it right! Given the dehydration which takes place, it’s extremely important to follow a simple but strict procedure. I’ll be with you the whole way through this process, until both of us are confident that you’re back on course to your everyday diet.

We will be fasting in Hungary’s rolling Börzsöny hills, less than 10km from the most scenic spot on Europe’s greatest river: the Danube Bend (pictured above). Hungary’s climate is perfect for fasting in the spring and autumn, with plenty of sun and average daytime highs around 20-22C (70F).

Our accommodation lies on the edge of a small village called Kóspallag, and features a large garden with fields and miles of forest directly behind. There are several natural springs in the vicinity from which we shall drink throughout the duration of the fast. The house is newly built, with a sauna and jacuzzi to help promote detox. Standard accommodation consists of a shared twin room with en suite bathroom, but a few private rooms are available for an additional fee.

Day 1 (Friday), pre-fast:

After arriving, we will share a “last supper” before the water fast itself begins. This will be an opportunity to bid a conscious farewell to food for a week, as well as to examine how everyone feels about this.

Days 2 – 8 (Saturday – Friday), 7-day fast:


Local forest paths

Each day consists of a combination of loosely structured and free time. All programs are optional except for the daily group sharings, when we sit in a circle and check in with each other about how things are going. This is an opportunity to share how you feel, whether physically or emotionally. There’s no need to talk if you don’t feel like it, but you do need to be present so that we can all look out for each other.

This is one of the huge strengths of a fasting retreat: you’re not alone. You’re in the same boat as your fasting brothers and sisters.

We all help each other along, and by the end of the retreat deep friendships have often begun to evolve.

Beyond the daily sharings, optional programs are offered through each day, including:

— Gentle yoga/stretching (twice per day)
— Group discussion: sharing experiences (twice per day)
— Daily walks in nature
— Lectures on fasting and detox
— Meditation
— Support for anyone who is having a hard time 🙂

For anyone interested, there will also be opportunities to practise:

— Shanka prakshalana (yogic intestinal wash)
Dry fasting
— Sauna and jacuzzi, to promote cleansing and detox

Day 9 (Saturday), post-fast:


One of the hardest parts of any fast is the refeeding period following the fast itself. It’s so easy to get it wrong, either by eating the wrong foods or by by uncontrolled binge eating! After breaking the 7-day water fast on Friday evening, we will focus on establishing a healthy path back to an everyday diet! During this time, there will be opportunities to:

— Discuss strategies about how to continue the path back to normal eating after the retreat ends
— Prepare for the return back to everyday life and society
— Continue cleansing through more sauna and jacuzzi

Over the last 24 hours of the retreat, we’ll be gently stimulating the digestive system back to life through the most appropriate smoothies and solid foods. By the time you go home, you should be perfectly capable of continuing without any digestive problems.

If you are interested in exploring your limits, your fears and addictions, if you want to come to a deeper understanding about who you are, and if you have some prior experience in fasting, then you can learn a lot from this retreat. I myself have extensive experience with up to 21-day water fasts, as well as 5-day dry fasts (no food, no drink), and would like to pass my own knowledge on to you.

About 7-day water fasts in general:


Our local spring

Experience with 7-day water fasts is essential for anyone interested in attaining a deep level of cleansing. For most people, an annual 7-day water fast should be enough to maintain health into old age (in combination with a healthy lifestyle). For those with deeper health issues, water fasting can be used as an effective healing modality, and 7-day fasts provide powerful momentum in this direction. (More information here.)

If a 7-day water fasting retreat feels too long, you may want to consider trying out a 3-day water fast at home first. The truth is, though, that often participants arrive to the retreat having practised only a couple of 24- and 36-hour water fasts beforehand. They do fine – and so will you!

Prerequisites for and further information about this retreat:

— Prerequisite: prior experience of at least one 36-hour water fast.
— Please note that this retreat is not medically supervised. There will not be a doctor on-site. Anyone with a medical condition who is considering this retreat should discuss this with their healthcare professional. (Please feel free to discuss it with me as well, using the registration form below.)


After applying using the form below, I will reply and send a link for payment via credit card. Participation in the retreat is secured once payment has been received. Once received, payment is final and non-refundable.

Price includes accommodation, participation in all activities during the retreat (including sauna and jacuzzi), meals before and after the fast, VAT and IFA (tourist tax).
If necessary, free transportation (car share) can usually be provided to Kóspallag, which is approximately a one-hour drive from Budapest.
Getting to Budapest is easy from all across Europe. Most budget airlines have round-trip tickets for about £100/$130.

Fasting in a time of lockdown

‘This is the perfect time to fast…’

I’ve heard this sentence, again and again, repeated verbatim by numerous clients since most of the world went into lockdown earlier this year as a result of Covid 19. Now that many of us are slowly returning to a less restrictive regime in life, I thought this might be a good time to reflect on how lockdown has influenced people’s actual experience of water fasting.

In many ways it’s true: lockdown really is the perfect time to fast. In becoming socially distanced from one another, we’ve enjoyed an opportunity to become closer with ourself. Locked into our homes, locked away from the outside world, this has been an inherently inward-turning (yin) period for us all – as opposed to the more outgoing (yang) mood of everyday life. Since we’re not running around, out on the town any more, we’d may as well just stay at home and simply be.

Lockdown has forced us to slow down. Of course, fasting does the same. It too is also an inherently inward-turning occupation, with consciousness directed towards both the physical detox and healing taking place inside the body, as well as towards the deeper emotional and spiritual layers within our being. In short, the yin characteristics of the world under lockdown reflect and naturally support the yin elements of fasting.

Fasting at home instead of at the workplace

Beyond the general parallels between lockdown and fasting, lockdown has also brought specific benefits in terms of the logistics of fasting. For example, with most people working from home, there’s been little or no need to endure the stress of fasting at the workplace. If you’re feeling low on energy, you can just lie on the couch and get on with the day’s job: a much more comfortable solution than the average office desk and chair. I’ve even had several clients who have worked from bed most days.

For many, lockdown has also brought a reduced workload and, with it, the chance to work more slowly, as the body permits. This leaves more energy for focussing on the fast – more than would ever have been possible under normal circumstances. For those who have been furloughed, fasting has even served as a substitute for a job: that is, a full-time occupation in itself. In the end, isn’t that how fasting should be?

Another benefit of fasting at home instead of the workplace is not having to tell your colleagues about your crazy plans. For some people, though, this has been a mixed blessing, because lockdown has consequently meant living in closer proximity with partners and family who may not be 100 percent supportive of water fasting. (Let’s be honest, for most people, the last person you want to tell about your water fast is your mother!) Whether parents, spouse or other, this has often put added pressure on relationships which are already stressed by living together under one roof, 24-7, for weeks on end.

Anxieties and distractions

Although lockdown has positively influenced many people’s experience of fasting, it hasn’t always turned out to be beneficial. Sometimes the emotional impact of lockdown has hit a little too close to home, intensifying anxieties which already lie at the heart of any water fast. For instance, many people find that they need distractions in order to survive the unrelenting ‘boredom’ of a water fast. Unfortunately, though, lockdown has severely restricted the spectrum of possible distractions normally available. Unless you’re happy with marathon sessions on Netflix, you’re pretty much stuck. You can’t go out and meet with friends. You can’t go out shopping. If you’re unlucky, you can’t even go out and spend a little time in nature. Everything is closed.

Without external distractions, there’s no choice except to turn inward. For many people, though, the introspective gravitational pull of a water fast already poses a challenge in itself. Combined with lockdown, it can become too much, uncovering parts of our personality which we’re not ready to face. The mirror is simply too clear. As if this weren’t enough, let’s not forget the whole reason we’ve been locked down: Covid 19. Lockdown has been a constant reminder of our human fragility and, ultimately, mortality. Water fasting is too.

For me, this is one of the fundamental reasons to practise water fasting. We feel the fragility of our human bodies, and, by surrendering to the fast, connect with a deeper part of our being. Or, to put it another way, by letting go of our usual attachment to finite, physical Self, we begin to taste the infinite within us.

A broader perspective

The same applies to all of lockdown. Similar to the beginning of a water fast, we have battled giving up everyday habits: little things taken for granted, like breathing fresh air outside or going for a walk. Furthermore, many people feel a deep resistance and resentment to the way that the democratic freedoms we normally enjoy have been swept aside. In some locations, rules have even been imposed which bear little relevance to the actual science of disease prevention. Whatever we feel about the political motives of lockdown, though, this whole situation invites us to explore where true freedom lies. Just as in a water fast, so long as we resist giving up our everyday habits, we will never find the true potential of who we are. We can either be prisoners on the outside, beholden to the limitations of a body suffering from detox – or, equally, to a world suffering in the throes of Covid 19. Or, alternatively, we can find freedom on the inside: a strength which is capable of transcending any crisis in the outside world. The choice is ours.

Ultimately, the whole experience of lockdown itself constitutes a kind of figurative ‘fast’ from modern consumer society. Understandably, this hasn’t been easy, in the same way that water fasting also poses a challenge for the vast majority of people. Perhaps, though, this is all for the best. For lockdown provides a new perspective on our often dysfunctional relationship with family, friends and colleagues, our job, our environment and, more generally, with all of Nature. Hopefully, it will also act as a global reset for the future – in precisely the same way that a water fast offers the possibility to heal from destructive old habits and addictions. The inconvenient truth is that, for a long time now, the trajectory of modern living has been unsustainable. Sometimes giving up our comfort zone is necessary to ensure future health and happiness.

Spiritual fasting in Lent (or any other time)

25th February, 2020
Tomorrow marks the beginning of what for many people is the most important time of the year in terms of spiritual fasting. For Christians, Lent constitutes the 40-day period prior to Easter, serving as a reminder of both Jesus’ 40-day fast in the desert as well as the final period of his life leading up to the crucifixion. It is a time for introspection and reflection on life.

Whether or not you are a Christian, water fasting naturally supports this shift towards looking inside ourselves. By giving up food – the elixir of life for our physical body – we become able more naturally to identify with that deepest part of ourselves which has no need for physical sustenance: our spirit, our soul, our innermost Self.

Reaching the point of opening up spiritually through fasting isn’t always easy. It requires surrender. Surrender not just of food, but also surrender of our ego which wants to eat the food, which wants to find comfort and love in food. It takes a huge amount of courage to let go of all that wanting, to let go of our comfort zone through eating.

So long as we are engaged with that struggle with ourselves and our egos, engaging in spiritual practice is next to impossible. While fasting, it’s easy to think that we ‘should’ be feeling closer to God, that we ‘should’ be happily meditating or praying, but the truth is that often the opposite is the case. We can feel far removed from God, and the idea of meditating or praying can create mountains of resistance inside us.

The beautiful irony, though, is that when we finally do let go of our comfort zone and truly surrender to the fast, we find that the love we crave is already there within us: within our own soul, one with the universe and God. Just as food is for the physical body, this love is the elixir of life for our spiritual ‘body’.

Until we reach a point in the fast of surrendering our ego, it’s easy to feel down or inadequate, to feel guilt or even self-hate. Instead, please, please try and be kind to yourself. We’re all only human. Even if you never reach the point of fully surrendering yourself to your fast, it was your spirit, your soul, your innermost Self which called you to fast in the first place. Sometimes it takes time for the clouds to clear and for the sun to shine. So stick at it! Sooner or later you will feel the warmth of golden rays on your face.

Fasting against coronavirus (Covid-19): how to boost immunity and maximize health

For water fasting to heal Long Covid, please click on the link below for my more recent article:
Healing from Long Covid with water fasting

Written at the start of the pandemic, the extended article below argues that the best thing you can do to strengthen your immune system against Covid-19 is to undertake a 7-10 day water fast or, ideally, a 21-day fast as soon as possible (see Section 3). For most people, fasting is also advisable during illness, especially if you begin as close to the onset of symptoms as possible (see Section 4).

(1) A no-win scenario?

The rapid spread of Covid-19 throughout China and, increasingly, across the globe rightly has many people worried. Currently, the number of infections continues to double every few days, with the official death rate holding steady at just over two percent. If this trend continues – and it is only an if – then the number of casualties will eventually extrapolate to many millions of deaths worldwide.

Is water fasting safe?

Many people are convinced that water fasting must be dangerous. Unfortunately, this is mostly based on fear, misinformation, and only a minimal number of actual cases. This video and newly expanded article examines all the facts through a variety of different issues, also covering the exceptional circumstances in which… (more below)

water fasting really does become unsafe. Knowledge is power: so read on, gain the facts, and fast with confidence – not fear!

Article sections: (1) Fears about fasting, (2) Is water fasting safe?, (3) Why water fasting is safe, (4) Fasting versus starving, (5) Discomfort versus danger, (6) Danger arises when brain overrides body, (7) People for whom fasting is dangerous, (8) Refeeding and eating, (9) Final thoughts

1. Fears about fasting

Let’s get straight to the heart of the matter. Most people are afraid (or at least a little anxious) about giving up food. Fair enough, if you stop eating for too long, starvation is the only possible outcome. So when we hear wildly dramatic statements like: ‘if you water fast, you’ll die’, a part of us resonates with the idea deep down inside.

In combination with this instinctive response, our more rational mind can also easily fall prey to fears about fasting. Over the last 100 years, modern Western medicine has disempowered our trust in ourselves and our bodies’ own natural wisdom to heal. Instead, pills and potions have become the name of the game, and today we entrust our wellbeing to medical doctors instead. With a training based almost entirely around pharmacology, it isn’t that surprising that even most well intentioned MD’s simply don’t get it. Fair enough, when your whole world revolves around putting medicines into the body, the idea of not putting in anything at all seems all the more contradictory, if not downright dangerous.

2. Is water fasting safe?

So can you die while water fasting? I won’t lie to you. The answer is yes – just like you can die getting up in the morning or crossing the road. All of life is a risk. Taking a full perspective on the issue, though, water fasting is totally safe for the vast, vast majority of people.

Don’t just believe me. Believe Google. I would suggest that anyone who has lingering doubts type the search terms “water fasting” and “death” into the world’s largest search engine, and see what comes up.

Essentially nothing.

Yes, a few isolated historical cases have been documented in which people died.Most of these, however, involved fasts lasting several months, and were conducted with disregard for the body’s warning signs (to be discussed later in this article, as well as in my video-article on fasting to lose weight).

Besides this, you’ll find only a lot of heated personal opinion as well as vague, unsubstantiated horror stories.

3. Why water fasting is safe

It’s only been in the last hundred years or so that those of us living in the Western world have had unlimited access to food: every day of every month, year in, year out. Before that famine was an unavoidable fact of life – as it still remains across other regions of the Earth today.

On a physiological level, the initial stages of famine are identical to fasting.

Over the millennia humankind has proved itself remarkably resilient to famine, and each of us is designed to be able to last 6-9 weeks, if not more, without food. You might say that we are born to fast as much as we are to eat. Both are – or at least should be – totally natural to us.

It’s in our blood. We’ve been doing it for hundreds of thousands of years, and we’re still here to tell the tale!

To take another historical perspective, think of it like this: if fasting were somehow dangerous to us, evolution would have weeded out those of us incapable of fasting long, long ago.

4. Fasting versus starving

I’ve already mentioned the obvious fact that if you stop eating for too long, starvation is the only possible outcome. This really is the crux of the matter in terms of safety.

Fasting means that your metabolism is able to sustain homeostasis: a state of equilibrium maintained between the various elements of the body and among the various physiological processes which keep you alive. Yes, you’re burning fat, but all your other body systems are stable and therefore running safely.

Starvation begins once the body can no longer keep things in balance, and homeostasis is lost. As mentioned above, it usually takes at least 6-9 weeks of continuous fasting to reach this point. Usually, this is triggered by fat levels having dropped to approximately 2% of body weight, which causes the body to start cannabilising muscle tissue for fuel, as well as eventual damage to the inner organs. Another dangerous situation arises if electrolytes gradually shift out of balance, making homeostasis impossible to maintain. Again, this is highly unlikely to happen in under 6 weeks of fasting – especially if you began the fast as an otherwise healthy person. If you do reach the initial stages of starvation, though, it’s imperative to end the fast immediately.

If fasting is safe and starvation is unsafe, all you need to do is listen to your body. There are very clear warning signs. Once fat levels drop dangerously low, your body elicits an unmistakable and irrefutable hunger: one totally different from the kinds of hunger which often come and go throughout any water fast. If electrolyte levels become dangerously imbalanced, symptoms may include nausea, brain fog, cramps and other issues. Unfortunately, these symptoms can be almost identical to those which arise through normal cleansing. Often, only the context in which they appear provides the definitive clue, but a water fasting expert should be able help identify these, especially if they’ve been working with you throughout the fast.

5. Discomfort versus danger

In fasting as well as in the rest of life, discomfort and danger are clearly two entirely different issues. Detox symptoms may be uncomfortable, but this does not mean that they’re inherently dangerous!

The simplest analogy would be to consider the flu. Your muscles are aching, you feel a little nauseous with a headache to boot. You’re certainly in discomfort, but is it dangerous? Of course not!

Essentially, flu often presents exactly the same spectrum of symptoms (with the exception of fever) as you might experience on a water fast. Why? Because in both cases your body is detoxing. The only question is whether you’re cleansing from a virus or from the toxins released through the fast.

6. Danger arises when brain overrides body

Fasting becomes dangerous primarily when we allow our mind to dictate what it thinks is best for our body. If, in contrast, we simply tune into the messages our body is continually sending us throughout the fast (as well as every day of our lives), and if we act accordingly, then we have nothing to fear. Body knows best.

Here are two classic examples.


Many people follow a protocol of drinking at least ‘x’ litres or fluid ounces per day during their fast – in other words, they aim to reach a ‘magic number’ formulated in the brain, not the body. We’ve all heard about how it’s important to stay hydrated. There’s a certain logic in this. If you’re water fasting, the water helps to flush the toxins out from the tissues. So surely more is better. I even know of one medically supervised water fasting centre in the US which prescribes their patients a minimum of 140 fl. oz. of water per day. That’s over a gallon!

The problem is that drinking more than you actually require slowly washes out electrolytes. (Exactly the same issue can play out in endurance sports. No-one dies from dehydration during competition, but there have been occasional cases of marathon runners suffering sudden death from hyper-hydration.)

Considering that electrolyte depletion is already one of the dangers in an extended fast, drinking too much should definitely be avoided. The immediate solution, however, is not to take an electrolyte supplement (as many people naturally assume). This only kicks the can further down the road, correcting for one bad mental decision by introducing yet another variable into the equation. No. The solution is simply to follow your thirst.

Thirst is there for a reason. It’s your body’s way of telling you to drink! I always recommend that my clients use thirst as the default setting to determine the quantity of water they drink, and nine times out of ten things run perfectly. On the odd occasions that problems arise, sometimes the solution is to drink more – but, equally, sometimes it is to drink less. It all depends on which particular symptoms appear in the body.


As mentioned above, ignoring the body’s warning signs can get you into trouble, causing danger. But what does this really mean? It means that your mind overrides a particular bodily symptom, in a decision to ‘push through’ the fast.

Sometimes you do need to push through a particularly acute wave of detox. Other times you need to abort the fast. At times it can be exceedingly difficult to know which is which, and what the right thing is to do. The ultimate decision, though, should not be based on willpower (a mental attribute) but rather trying to tune into what your body is feeling. I’ve had clients suffer through truly horrendous detox symptoms, and although they’ve wanted to stop (a mental state), deep in their body they’ve known that continuing the fast was the right thing to do. Similarly, I’ve known cases where the actual physical symptoms were quite mild, but the person concerned drove straight to the ER because they just knew deep in their body that something wasn’t right. It’s in cases like these – in which physical discomfort can make it difficult to objectively observe yourself – that an external expert opinion can prove indispensable.

7. People for whom fasting is not safe

Although water fasting is completely safe for well over 99% of the population, there are nevertheless exceptions to the rule. It’s extremely important to understand which conditions and situations preclude fasting! These are listed below:

Cardiac issues

The only cases I’ve heard of which have ultimately resulted in death concern people with underlying heart problems. This does not rule out fasting per se, but it’s crucial that anyone suffering from such a condition discuss it first with their doctor.

There are two potential complications caused by a weak heart. First, cleansing puts a strain on the heart. In the same way that people experience a pounding heart during the flu, a very similar symptom can present while water fasting as well. This can be further compounded if blood pressure falls excessively. (Otherwise, lower blood pressure is a perfectly normal mechanism of a water fast which facilitates detox.) Although an elevated heartbeat is perfectly safe for the vast majority of people, it could eventually cause problems for someone with cardiac issues.

Second, if electrolytes fall too far out of balance, this can ultimately lead to cardiac arrest. A whole array of symptoms makes itself increasingly obvious before finally reaching this point, but if the body’s warning signs are repeatedly ignored, then consequences are inevitable.

Type 1 diabetes

Those with Type 1 diabetes are usually told they cannot water fast under any circumstances. This can be true if pancreatic function is already too diminished. Nevertheless, water fasting is certainly possible in certain cases, and I myself have worked successfully with Type I clients. Before considering such a fast, though, it’s imperative that anyone with Type I diabetes discuss it first with their doctor.

In contrast, Type 2 diabetes usually responds extremely well to water fasting. This is the type of diabetes most of us are more familiar with, involving the body having built up resistance to insulin, as opposed to damage to the pancreas (Type 1). Since the issue here concerns hormonal imbalance rather than physical dysfunction (as in Type 1), a water fast’s hormonal reset often leads to a full healing of the disease.

Toxic drugs and medications

If you’re taking prescription medication immediately before your water fast, you’ll need to decide whether to continue with your meds, reduce dosage or come off them altogether during the fast. This is an issue which should always be discussed with your doctor as well as a fasting expert, so you can find a solution which maximises the healing potential of your fast while keeping you safe.

Certain drugs and medications can cause nasty detox symptoms at the best of times. In everyday life, this can mean both side-effects while taking them, as well as withdrawal symptoms afterwards. Coming off such drugs ‘cold turkey’ and diving straight into a water fast can make things much, much worse. In such cases, the fast is too powerful, the rate of detox is simply too high, and the body can become overwhelmed – possibly leading to death. Alcohol, opiates (such as Methadone) and certain anti-depressants (such as benzodiazepenes including Xanax and Valium) all fall into this category.

As much as coming off your meds for a fast might be a problem, the opposite can also be true. For instance, certain common drugs used for Type 2 diabetes, such as Metformin, block the liver’s gluconeogenesis (the process of synthesizing glucose). This can cause serious complications because the metabolic circumstances during a water fast are almost the opposite from those in everyday life – that is, from the circumstances for which the drug was prescribed in the first place. In short, Type 2 diabetics normally benefit from lowering the level of glucose in the blood through a drug like Metformin. This is because Type 2 diabetics do not respond effectively to insulin, which would normally fulfil this function. During a water fast, though, glucose levels are already significantly lower than in everyday life. This means that a drug like Metformin can force the body out of homeostasis, making a water fast highly dangerous.

Psychological imbalances

For almost everyone, eating goes well beyond the purely physical realm of simply fulfilling nutritional requirements. Of course, we also eat for emotional reasons, in order to feel comfort, to relieve boredom, to calm anxieties. Since psychological imbalances all express themselves through various painful emotions, a water fast inevitably impacts further on those same emotions.

It’s often a double-edged sword.

On the one hand, taking away the comfort of food and all the other emotional crutches of eating can prove exceedingly difficult for those suffering from psychological imbalances. This holds especially true for those with eating disorders – the vast majority of which are primarily psychological based and not physical.

On the other hand, it’s also true that many psychological imbalances are caused by hormonal imbalance – and one of the best ways to restore hormonal equilibrium is through an extended water fast. In such cases, healing the hormonal imbalance also heals the root of the psychological imbalance. In the 19th century, for instance, water fasting was even used to successfully heal schizophrenia.

Rare metabolic disorders

There exists a very small number of rare metabolic disorders which makes water fasting impossible. Most of these involve the inability to switch over to ketosis once glycogen stores are exhausted. Fortunately, the body provides extremely clear warning signs. Severe nausea and vomiting in the first 24-48 hours of a water fast almost always indicate that the fast should be aborted, regardless of the underlying cause.

Fasting with any medical issue

Above and beyond the medical issues described here, it’s always best to discuss any health conditions you may have with both a medical doctor and a fasting expert before embarking on a water fast. This holds true for any fast longer than 24 hours, and is especially important for fasts over 3 days. It’s always better to be safe than sorry!

8. Refeeding and eating

It may come as a surprise, but the most dangerous part of a water fast isn’t the fast itself but rather refeeding and eating afterwards. This applies especially to fasts of approximately 10 days and longer, in which so-called Refeeding Syndrome can develop.

Refeeding Syndrome can occur as the body shifts away from ketosis and back to a primarily carbohydrate-based metabolism. In order to manage this transition, the minerals potassium, magnesium, phosphate and vitamin B6 play a decisive role in shifting position and changing their biochemical function within each cell. The problem develops if you eat too many calories too soon, because these minerals will not have arrived at their new ‘destinations’ and therefore will not be able to perform the functions required of them. The initial stages of Refeeding Syndrome cause oedema and cramping, especially in the fingers and toes. If calories are not restricted at this point and the body’s warnings signs continue to go unheeded, this can eventually lead to nausea, heart arrhythmia and finally cardiac arrest.

I would venture to guess that about half of all people who undertake an extended fast experience the initial stages of Refeeding Syndrome during the first few days of refeeding. I certainly did myself on several occasions, before I understood what was happening! Although potentially life-threatening, Refeeding Syndrome is nevertheless something that most people pass through without any serious problems.

In addition to Refeeding Syndrome, the other main issues during the refeeding period concern digestive problems – which, again, are usually caused by eating too much too soon. There are two dangers: overloading the GI tract before it is capable of (1) producing the requisite enzymes for digestion and (2) physically moving the food through the intestines (peristalsis). As with Refeeding Syndrome, digestive problems tend to occur on longer fasts, in this case from about a week or longer.

One final problem caused by eating too much too soon is that the ‘wrong kind’ of fat can start accumulating. Instead of gaining normal subcutaneous fat – the kind most people notice around their waist line and elsewhere – the body prioritises fat around the inner organs in the period after a fast. This is the kind of fat which, in higher quantities, has been linked to an increased likelihood of chronic disease in general.

If you need help in designing your own refeeding program, I offer a pdf in the shop here. Alternatively, my water fasting clients receive a personalised refeeding plan through daily video calls, as part of full coaching.

9. Final thoughts

Although this article is starting to read like a water fasting horror story, the truth is that nothing could be safer in the whole world. The real horror story revolves around eating – and especially so in the modern Western world. Bad eating habits cause obesity, diabetes, cancer, cardiovascular disease… The list goes on and on. If the number of documented deaths through fasting over the last century can be counted on the fingers of one hand, how many millions of deaths can be traced each year to eating? Try Googling that!

Or just trust in yourself and in your body’s innate wisdom, and fast.
