What are the benefits and the challenges of a 3-day water fast?

Of all fasts, 3-day water fasts are in many ways the most important to learn how to master. This is the period your body needs to begin unlocking your healing metabolism and start reaping the benefits. These 3 days are also the stepping stone required to move on to even longer fasts, in which even deeper healing can occur. The more you practise the 3-day fast, the easier you’ll find water fasting of any length. To be honest, though, your body's adaptation to the 3-day water fast is also often the hardest!

Testimonials

Sungho K.

I worked with Tallis on a 3 day water fast. I had been struggling with several conditions that even Harvard Medical doctors had no idea how to help or cure. My main issue was that I had awful pain every, single time I ate. My mood was also terrible and I was exhausted all the time. To be honest, I was skeptical working with Tallis would help. After all, I had been just about every type of doctor trying to find relief for my suffering. Firstly, I was surprised to find that Tallis was incredibly knowledgable. I never had to explain any of my medical conditions, which is rare, even when working with medical professionals. He was also kind and patient. I had a long list of concerns but he took time to address all of them. Because he was there to answer every concern, I always felt reassured and safe. Even though the support was online, there was never at time I didn’t feel fully supported by Tallis. With the help of Tallis, I successfully completed my first 3 day fast. I had attempted to do water fasting on my own before, but never made it past 36 hours. I know I could not have done it without Tallis’s support.

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.

Tallis helped me complete my very first water fast. I decided to go for 30 days and he was an absolute expert all the way through. Somebody that gives it to you straight and is also very compassionate. Any fast I ever need to do, I will always do it with him.
