Tallis is one of the world’s preeminent water fasting coaches and is the #1 option for those wanting guidance while fasting in the comfort of their own home. As a naturopathic doctor, he’s incredibly knowledgeable about fasting, re-feeding, and the healing processes within the body. Tallis is also a classically trained pianist and his musical quality is evident in the tone and cadence of his speech, which is quite relaxing and reassuring.

During my extended fast, he was always present, patient, responsive, and thoughtful in his coaching feedback throughout my fast as well as after my re-feeding was complete. There was a point where I wanted to quit prematurely, but Tallis reassured me that what I was experiencing was normal and it was safe to continue. I couldn’t have made it 33 days without him and recommend him whole-heartedly for anyone looking to reboot their system.

I worked with Tallis early this year (2026) undertaking initially a 21 day fast that I chose to extend to 28 days. Tallis's structure and process of coaching as well as his thorough awareness of what expectations can be anticipated throughout my fast were invaluable. I am due to 'top up' my self with a 7 day fast running up to and through the coming Summer Solstice. Overall, the cleansing process of fasting to an extended time period has been very valuable indeed. Both physically and mentally my results have been beyond expectation – having Tallis as my 'wing man' throughout was worth every penny.

Tallis has guided me through 5 extended water fasts over 4 years. I did a 5day, several 7day's and a 10 day fast. We do 15 minute video calls throughout the fasts which really helps with motivation and accountability. Tallis is an expert on water fasting and he is the best at coaching me through the hard parts. I do water fasting primarily for health benefits as I am an athlete.

I just completed a 21 day water fast with Tallis. He is an excellent and caring coach. He excels at suggestions to mitigate symptoms of fasting, what is happening in the body, and encouraging you when you are down. His fee's are very reasonable for the amount he works with you before and after the fast. I had significant improvements in my mood and energy and plan to complete more fasts with Tallis' guidance.

I know I wouldn’t have been able to move forward with a longer fast without support. After looking at other options I am happy I went with Dr. Tallis. I have done a few long fast before but also stop 7+ days because I couldn’t trust the sensations I had in my body. With his knowledge and consistent support I was able to move to 21 days. I know I would have stopped before that. I also learned to trust my body more as his approach is very different than what others are saying on the random fasting groups you find online. I have more healing to do and anything longer than 7-10 days I’ll be getting help, especially with refeeding. All the best to you reader and your fasting journey. It’s always better with a coach. You aren’t alone.

I feel so fortunate that Tallis has helped me with fasting. He has so much professional knowledge with how the body works especially when it comes to fasting. He is super easy going, very down to earth, and lives his truths. I definitely believe in the benefits of fasting and I always know I'll be successful during my fast when I bring Tallis on board as my coach.
