Every serious fast has a before, a during and an after

Fasting days should not be treated in isolation. Preparation, the fast itself and refeeding form one continuous process — and nutritional therapy can extend that work much further.

I have now completed a 7-day and most recently a 21-day water-only fast while working with Dr. Tallis Barker. There is no way I could have done these fasts successfully on my own. Tallis is very knowledgeable, understanding, and kind. He guided me through the whole process—pre-fast, during the fast, and post-fast—so that I felt safe and confident throughout. I would never attempt a long water fast without his guidance. If you are going to do a fast, I highly recommend working with Dr. Tallis Barker.

Tallis is a fantastic water fasting (and dry fasting) coach. Having suffered from long covid for almost a year, I underwent a 4 week fast under his guidance. He always reassured me, explained everything and guided me before, during and after the fast. Thank you Tallis - I will definitely use you as a coach for any future fasts. I cannot recommend him enough.

Tallis was so helpful for my fasting experience; the support was absolutely necessary for me to succeed. It was just what I needed to get through it, he was more than informative, and very personable to work with. He was also flexible when I had some scheduling difficulties. I wouldn't hesitate to recommend him to anyone interested in pursuing fasting for their health needs.

Tallis helped coach me through a 40 day water fast recently. His daily guidance was strengthening, informative, and encouraging. He is very in-tune with the human body along with the fasting experience. Tallis provides a calm and steady hand through an experience that can be jostling and shaky. I can say that I needed him, for certain. And I’m not sure if I could have done it without him. I would recommend Tallis to anybody. Thank you for your work, Tallis.

Tallis is a wonderful fasting guide. I was lucky enough to have his guidance over a 37-day water-only fast, and having the support of his expertise and his belief in my ability to complete the fast got me through some very difficult moments. Tallis is unusual in having a deep knowledge of the literature and science of fasting coupled with a sense of humility, lightness, and spirituality about the discipline. At every step of the way Tallis was able to recognize and explain any side effect I experienced, and I was able to shed any fear that I had thanks to his guidance. Our video calls were a real lifeline, and I absolutely would not have wanted to go through this process without such a kind, warm-hearted expert virtually by my side.

I've completed both 21 and 14 day fasts with Tallis this year. I would never have been able to accomplish either fast without Tallis!  He's incredibly knowledgeable and easy to speak with. I appreciate that he is not only there for you during the fast, but also helps with the before and after. I always felt like I was in good hands and he put to ease every concern or question I had.  For anyone who is wondering if they should take the leap, do it! It has been an amazing experience.

This is my second 7 day water fast experience with Tallis.  First was pretty difficult because I was in really bad shape from Long COVID but in the long run it was a critical component of regaining health.  This second was a year later was to reinforce and strengthen my healing trajectory. I’ve told Tallis both times he deserves a humanitarian reward for virtually holding the faster hands with encouragement, hope, and his extensive knowledge about the process.  I’m about two weeks post fast and I’ve already noticed some hanging on symptoms disappearing in regards to my heart beat and to odd muscle twitches.  I’m so grateful I found him! And hope to do this yearly as it has become a sacred process.

I recently took on a 40 day fast with Dr. Tallis’ help. Whether you’re motivated by the Spirit or just addressing physical issues I would highly recommend Tallis. He helped me navigate the unknown and truly put my anxieties at ease with his experience and willingness to get help get through. We are fundamentally outside of the initial re-feeding window. He blessed my fast and my exit path. Many blessings!

Frequently asked questions

What does Dr. Tallis Barker specialise in?

Dr. Tallis Barker specialises in extended water fasting, including fasts lasting from several days to several weeks. His work covers preparation, one-to-one coaching, refeeding and nutritional therapy.

Does Tallis work with people who have chronic health problems?

Yes. A substantial part of Tallis’s work involves people who come to fasting with persistent or complex health concerns, including digestive and gut disorders, post-viral illness and Long Covid, inflammatory and autoimmune conditions, metabolic or hormonal concerns, and cancer. This describes the people he works with; it does not mean that fasting is appropriate for every condition or every person.

Is Dr. Tallis Barker a medical doctor?

No. Tallis’s title “Dr” refers to his Oxford D.Phil., an academic doctorate in musicology. His professional health qualifications are in nutritional therapy and naturopathy.

Is extended water fasting safe?

Extended fasting involves significant physiological changes and is not appropriate for everyone. Individual circumstances matter, particularly where there is a medical diagnosis, prescription medication, low body weight, pregnancy, an eating disorder history or other relevant health considerations.

How long should a water fast last?

There is no single ideal duration. Previous experience, body composition, health history, objectives and how the individual responds during the fast all matter. Longer is not automatically better, and this is something we examine during our initial consultation.

Can I work with Tallis for nutrition without fasting?

Yes. Nutritional therapy is available independently. Clients do not need to have completed a fast or to be planning one.

What happens after an extended fast?

Refeeding is an essential part of longer fasting. Tallis’s fasting coaching includes support during the refeeding period, while nutritional therapy is available for longer-term dietary work afterwards.
