Water fast coaching and consultations

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 from across the world through fasts of 3 to 40 days
(CLICK HERE for testimonials)

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 (WhatsApp, Telegram, Skype) 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.

A single consultation via video call ($120 USD) is suitable for general advice about fasting or the planning of a specific fast and/or diet plan. Price includes an internet video call (60 min. via WhatsApp, Telegram or Skype), plus follow-up emails relating to the given issue.

  • A single consultation is also the place to start if you’d like full water fast coaching, but aren’t sure how long you want to fast. In this case, our video call will help you decide. Afterwards, you can convert to full coaching by simply paying the difference in fees for whichever length of fast you choose.

    I have completed a 28 day fast with Tallis.
    I have done a 21 day water fast on my own in the past but it has been much more difficult doing it alone.
    Tallis support and experience were extremely helpful.
    He is very knowledgeable about fasting and many issues about the body or mind.
    I would do it again in future
    He has a very understanding attitude and has used an individualistic approach to my personal situation.
    I was able to grow through this experience with him

    day 18 of my water fast..Doctor took a blood sample..everything normal except LDL cholesterol
    which he described as “awful” (measured190) maybe because of autophagy consuming fat?

    • Tallis Barker Ph.D. says

      Hi Curtis,
      I’m afraid the vast, vast majority of doctors don’t know how to interpret blood results while fasting. It’s not their fault: they’ve never had experience in observing the changes which take place! High levels of LDL are just one example, and are often completely normal while water fasting. As the immune system works on cleaning your cardiovascular system, LDL plaques are removed from the arterial wall and thus enter the blood stream for cleansing. This is picked up on the blood test. Your LDL levels should return to normal (if not lower than before) after the fast.
      All the best,

    I never would have believed I could do a 20-day water-only fast and have it be a really great experience. I don’t think I could have done it without the coaching of the wise and compassionate Tallis Barker. He goes beyond the call of duty to be a supportive, helpful, and instructional.

    I began just wanting to do a few days, then a week, then 2, and almost made it to three. The health effects, not to mention weight loss, were amazing. So much so I am looking forward to the next time I do this healing protocol—with the great coach Dr. Tallis Barker, of course!

  4. Tabitha says

    I’ve worked with Tallis on 2 major water fasting events. One 40 day fast in April last year and one 20 day fast in January of this year.

    Fasting is a particularly private experience and having someone to video chat with daily and send questions along the way has been my secret ingredient for success. My friends marvel at my willpower but the truth is that the success has been a combination of my intention and support from Tallis. Through both those journeys, Tallis was my partner and coach – proactively helping me anticipate and navigate through challenging moments and celebrating victories with me.

    I have experienced tremendous healing both physically and emotionally through these fasts and watched myself grow spiritually. I can say without a doubt that Tallis was a critical reason I have been successful both times. What’s also great is that he doesn’t stop when the fast is over – he helps you healthfully transition back to normal eating habits after the fast. Thank you Tallis for going through these incredibly personal and important journeys with me. I know this is not our last fast together as I intend to continue incorporating these fasting experiences into my life. I am grateful!

    After reading lots of information about waterfasting on the internet I finally made my decision. I really wanted to do a 21-day waterfast but I realized that I had no experience at all. For more than a week I did my research and I ended up at this website, http://www.waterfast.org. I had a very good feeling with the articles on this site, the personal fasting experiences of Tallis and his expertise so I asked him if he would like to be my coach. During my fast and also during the re-feeding process. Very good to hear that he was very excited as well so we started my 21-days journey. In fact in was not my journey, but our journey!

    Ofcourse I had my questions and a couple of times my concerns as well. Tallis gave me all the information I needed, even much more than that. I highly appreciate his involvement, good advices, knowledge and his professional but very personal approach. After 21 days I finished my fast succesfully, what a great experience! Both physically and mentally as well.

    I definitely recommend Tallis as a personal coach for anyone who wants to experience the special benefits of waterfasting.

  6. Emily says

    I am SO glad I worked with Tallis for my first 3-day fast. Coming from a history of binge-eating, I was terrified of bingeing partway through my fast. Tallis was such a wise, encouraging, and compassionate coach. With him, I felt safe in the lead-up to the fast, during the fast, and after the fast. He encouraged me to be “less than perfect” in my first 3-day fast, allowing myself to binge before and after and drink herbal teas during. It will definitely take a lot more experience before a 3-day fast is no big deal and I am able to healthily transition into and out of the fast, but the knowledge (in my body and experience, not just in my head) that I *can* choose not to act on binge urges, even just for 3 days, is invaluable.

    I highly recommend coaching with Tallis. Having a guide who has experience fasting and guiding others through fasts, and who is able to customize feedback to your specific situation and goals, is worth every penny and more. I will be working with Tallis again for sure.
