Water fast coaching and consultations (online)

Mugshot 2018 Kisoroszi garden (square)Water fast coaching and how it helps:

Hello, I’m Dr. Tallis Barker. In addition to the many articles and videos here on this website, I also provide more private and personalised support as a water fasting coach.*

I’ve successfully guided hundreds of people through fasts of 3 to 40 days
(CLICK HERE for testimonials)

Fasting by yourself can be lonely.

Some people need accountability.
Some people need a partner to keep them company through their journey.
Some people need sound advice, especially when fasting to heal health issues.
You can find all sorts of answers on internet forums – but are they right for you?

Whatever your needs, I’m here to help hold the space for your fast.

If there’s one thing I’ve learnt over the years, it’s that the emotional security provided by working with a coach makes the experience of fasting much, much easier. That security even tends to decrease the severity of detox symptoms – and when they do occur, I can help you find the most appropriate ways to relieve them.

I offer the following online services:

  • (1) Full coaching (see below)
  • (2) Single online consultation (see below)


Price includes:

(1) Preliminary video call (Skype, FaceTime or WhatsApp) before the beginning of the fast (@60 min.)
(2) Daily check-in video calls to discuss how you’re feeling (15-20 min. per day, every day except Sundays).
(3) Unlimited email contact every day for the full duration of the fast.
(4) Continued daily contact (video calls and email) after the fast, through the refeeding process.
(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. 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 obviously 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.

In addition to our daily video calls, you’re free to send me unlimited emails about any issue you’d like to share. In case of emergency (which is highly unlikely!), you’ll also have my personal telephone number.

After the fast:
For many people, the refeeding process after their fast is the trickiest period: both in terms of resisting the temptation to overeat, as well as in making sure you don’t overload your digestive system. We’ll stay in contact via video calls and email until both of us are confident that you’re back on course to your everyday diet.

Kóspallag: the village where we will be fasting

About this retreat:

spring retreat malnaskert 1

Our accommodation for the retreat

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 / PayPal. 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.

Diet 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 now 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.

What diet 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 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.
  3. Follow the instructions regarding payment by credit card or PayPal.
    Payment is due before our (first) video call.

*Please note: I am not a medical doctor and do not offer medical advice or supervision for any fast or diet following the fast. I encourage those with medical issues to seek advice from a qualified M.D., in parallel with my own knowledge and experience as a fasting coach.

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

This extended article 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.

Tasty, tangy sauerkraut soup

This is a tasty, tangy soup I enjoy especially after winter fasts – including the 7-day water fast I just finished yesterday. Before global trade overpowered local economies and foods, winter was always the time to eat preserved vegetables such as sauerkraut – especially in areas with a cold winter climate. Through the process of fermentation, sauerkraut gains many healthy nutrients not found in raw cabbage. Boiling the sauerkraut for this soup does unfortunately destroy its natural probiotics, but the organic acids produced by them remain intact.

In Eastern Europe and Russia, sauerkraut and grated cabbage (both raw and boiled) have always been used to break fasts. The high Vitamin C content and antioxidants help to revive the liver, and the fibre helps to ‘scrub’ out the intestines before returning to an everyday diet.

*Note: this soup is not suitable for those following a zero-sodium protocol.

Basic ingredients:

500g / 1 lb. potatoes
500g / 1 lb. sauerkraut
1 medium onion
1 large carrot
½ vegetable stock cube

Optional additional ingredients:

100g kidney beans (pre-soaked, boiled and ready to eat)
100g cannelloni beans (pre-soaked, boiled and ready to eat)
Black pepper
2 tablespoons olive oil

Total calories: 595; up to 915 with all optional ingredients

Makes 5 servings at 195 calories per full bowl of soup (350ml / 12 fl.oz.); up to 305 calories with all optional ingredients

Cooking instructions:

Put about 1.5 litres/quarts of cold, fresh water into a medium saucepan and start heating to the boil. While you wait, dice the onions, chop the potatoes and carrot, and throw all the ingredients into the saucepan. I usually add half a stock cube. If you’d like to avoid all added salt, then feel free to leave this out. Without a stock cube, though, the soup can taste too sour for many people. (The taste of sauerkraut is balanced evenly between sour and salty when raw, but when boiled in the soup, this shifts distinctly towards the sour range.)

While the stock cube dissolves, squeeze out some of the juice from the sauerkraut. (This helps to reduce the salt content.) I simply take the sauerkraut in my hands, and literally wring out the juice. Then add the sauerkraut to the pot, and pour in as much extra water as necessary in order to just cover the vegetables. I find the sauerkraut has a tendency to stick together in clumps, so it’s worth stirring into the other vegetables from the start. After the water reaches the boil, simmer (lid on) for 75 minutes and let cool.

This basic version of Sauerkraut Soup is fine for refeeding on Day 1 for fasts of 1-3 days, Day 2 after fasts of 4-10 days, and from Day 3 of longer fasts. The only reason not to recommend it immediately after all fasts is because of the relatively high salt content, which can contribute to oedema in some cases.

If you’d like to add some or all of the additional ingredients, the time to do so is after all the basic ingredients have already been added. Please note that black pepper is a stimulant and should be added only in moderation (if at all) after a fast. Olive oil should also be avoided immediately after longer fasts. Otherwise, a small quantity helps to bring out the soup’s flavours. Likewise, the beans should be added only if you’re sure you can digest them.

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 takes a look at all the facts, in order to help you decide whether water fasting might be for you.
