Hello. I’m Dr. Tallis Barker
I’ve successfully guided over 800 clients from across the world (US, Europe, Asia, Africa and Australia) through water fasts of 3-40 days. Having regularly fasted for 15 years, I became a water fasting coach after experiencing the deep cleansing and healing in my own body.
Although I coach fasts undertaken for numerous reasons (both physical and spiritual), I specialise in helping people heal from chronic illness such as:
- Long Covid
- Gut issues such as IBS, SIBO and ulcerative colitis
- Autoimmune issues such as allergies, asthma, chronic fatigue (CFS) and rheumatoid arthritis (RA)
- Hormonal issues such as insulin resistance, adrenal fatigue and hypothyroidism
- Fibroids, ovarian cysts and even cancer
OVER 800 CLIENTS
Successfully coached through 3 to 40 day fasts
For people unfamiliar with water fasting, the idea of giving up food can be frightening. But the fact is that homo sapiens have been successfully fasting for millennia.
Many people today practice intermittent fasting as a basic lifestyle, but longer fasts are also possible in order to go much deeper into healing.
Gut / Digestive illness
Long Covid
Autoimmune issues
Hormonal imbalances
You can completely recalibrate your body from the ground up, allowing yourself to heal. The way to do this is through water fasting.
Water fasting is completely safe for the vast majority of people. With guidance from an expert, you too can make the most of your fast and begin your healing journey.
FASTING TRIVIA
We all know the most famous examples of religious 40-day fasts, but you probably haven’t heard others.
For example, the Greek mathematician Pythagoras demanded that all his students undertake a 40-day fast in order to sharpen their minds!

Tallis is a rare coach, filled with the wisdom of experiental knowledge complemented with the explicit knowledge in different fields. He guides with love for his fellow men and a sincere passion for what he does. And thereby, fasting in itself is an extremely potent healing tool.

My husband John had a great experience with Tallis.
He had done various forms of fasting for years. Intermittent, 1, 2, or 3 day fasts, etc. But when he decided to do an extended water only fast for 7 days he knew he needed insight into how to properly execute it.
During some online research of fasting coaches, he found Tallis. He watched Tallis’s videos and found him to be both knowledgeable and easy to understand. He scheduled a single session to gather info on how to prep for the fast as well as what to expect during it and how to come off it.
Literally everything Tallis told him to do or expect to happen, happened. And he never got hungry. Even on day 1! With Tallis’s guidance it was literally simple for him to complete the 7 days. We can’t recommend Tallis highly enough.

Tallis’ guidance before, during and after my first 28-day water fast was invaluable to me. Previously, I had done a great deal of research and did several shorter fasts on my own, yet I learned a great deal from him. I found the 28-day fast with his coaching less difficult to do than my solo shorter fasts. He is very present and listens well, is patient, compassionate, conscientious, trustworthy and extremely knowledgeable. I felt he considered my own individual needs and did not apply a one-size-fits-all approach. I felt safe in his hands. He also encouraged me to listen to the wisdom of my own body which helped engender a sense of confidence in the process. I plan on coaching with him again in the future and highly recommend him.

In a field that has a lot of mixed messaging and confusion, Tallis applies his vast depth of knowledge and expertise from personal experience and supervision of other’s fasts. He cares about your health in a time when a lot of doctor’s just want to wipe their hands of patients with chronic illnesses. He has been a great resource and a source of encouragement for me as I have seen my condition improve through multiple fasts.

A life changing experience. I feel blessed to have found Tallis.

The twenty-one-day water fast that I undertook with Tallis was a completely transformational experience, not only enabling me to heal from some severe symptoms of Long Covid which I had been experiencing for over seven months, but also supporting the deepening of my spiritual journey. By Day 15 or 16, the brain fog lifted, and my mental clarity began to return, and I began to feel in a profound state of flow. What sets Tallis apart as an exceptional consultant is his gift for tailoring his impressive knowledge and personal experience of fasting to the individual client. Put another way, he is quickly able to filter out the relevant tips and information which will support the development of what you’re aiming for on your fast. He is also a very open person and will speak on a range of topics related to fasting, answering any questions that you may have. Tallis provides a unique gap in the market for helping people to resolve their chronic illnesses. He gives freely and shares generously from his well of wisdom and practical experience. He is also very astute and quick to pick up on potential pitfalls or adjustments that need to be made along the way. He allows you to feel safe and deepen into your process, whilst showing up reliably via video call for every day of the fast and refeeding process. I have already recommended Tallis to three people in my social and professional circles who I think could benefit profoundly from this experience of fasting in order to heal from autoimmune conditions. Thank you Tallis, from the bottom of my heart, for all that you are doing to help people and support their optimal health and flourishing, be that spiritual, emotional or physical!

Dr Tallis provided wonderful support during my water fast. He was able to explain so much about what was happening throughout the duration which really gave me the confidence i needed to get through it and also manage symptoms. Highly recommend!

Tallis was a wonderful coach while I completed a 20 day water fast. He was very helpful during some intense detox symptoms. He helped me every step of the way including during the re-feeding. I would highly recommend hiring him if you’re interested in having help as you water fast.

I highly recommend Tallis as a Fasting coach. He is very knowledgeable and very helpful. Prior to meeting with Tallis, I was unable to fast even 24 hours. But he walked me through a 21-day water fast & 1-week refeeding, w/ no issue. I have seen great health improvements since (fighting CFS/LC from vax) and owe this all to him!

3-day water fast
Of all fasts, the 3 day water fast is in many ways the most important. Three days is the period your body needs to unlock your healing metabolism and begin reaping the benefits. These three days are also the stepping stone required to move on to even longer fasts.
The 3 day water fast is also often the hardest. Because of this, it’s important do everything you can do to maximise your chances of a smooth experience.
