My 30-day water fast: benefits, healing and closure

Unlike the other articles on waterfasting.org, this essay takes a much more personal approach, both in style and content. I’m inviting you to share a very intimate part of my life, which I hope can provide context and perhaps even some insight when you fast yourself.


This fast feels like coming home…

It’s 2am, and I’m outside under a perfectly clear sky, watching the strawberry moon – swollen, full and veiled in a wash of pale red – sweep low across the sky, gradually sinking towards the horizon. And I realise: this is the night of Day 21. I’ve planned for my 30-day fast to end 10 days from now on the summer solstice. The synchronicity with heavenly clockwork somehow felt fitting, healing, given the weight of a month-long journey into the self. Until now, however, it hadn’t occurred to me that my fast had not only aligned with the sun, but also with the lunar dance above. 21 days: in one respect just another number. But to me it had greater meaning, bringing me back to my first 21-day fast over nine years ago. How different the whole experience felt now! And I realised, as the moon continued its imperceptibly slow slide towards the treeline, closer and closer, that this fast itself was a form of closure – not just of the last few years, but of a whole decade.

The deeper motivation of this fast was always going to be about closure: the putting to bed of the last five years, which saw us move as a family across Europe in the midst of Covid lockdown chaos, and then provide an emotional and financial foundation for our three kids while they finished growing up and establishing themselves as young adults in a new country. In short, it had been five years of pretty relentless adrenaline and cortisol – and I was very much worn out by it. It’s true that, throughout this period, I had been able to continue with my usual foundation practice of a couple 7-14 day fasts per year, in order to mitigate and partially heal from the accumulating physical consequences of chronic stress. But it really did feel like only damage control. I knew I needed something longer to achieve fuller benefits and healing. This is because access to more fundamental hormonal recalibration – in this case to undo dysregulated adrenal function driven by chronically elevated cortisol – can really occur on fasts of only 21 days and longer.

Fortunately, life had slowed down over the last year, and I knew time was ripe for a 30-day fast. Returning to a longer-term connection and closure with the period of my 21-day fast back in 2016, I was also now free to pursue this fast. It may sound strange at first, but, in the wake of my 2016 fast, I had been effectively banned by my family from fasting longer than 21 days until all three of our kids had grown up. It was entirely the right decision. My first 21-day fast had been conducted in retreat, alone in the countryside. A wonderful experience, but not one aligned with the real-life responsibilities of being a father of three! And so, as soon as my fast had finished, I had to dive back into the everyday world. This entailed driving back to town and collecting our youngest daughter, then 11 years old, from the train station after a school field trip. We hugged and started walking back to the car. Along the way, though, I noticed there were tears on her cheeks. I had no idea what was wrong, so asked why she was crying. To this day I remember her words verbatim: ‘Papa, you don’t look like Papa anymore!’ It was true. I didn’t look like Papa anymore. As a runner, I don’t carry a lot of excess fat anyway, and I really did look like skin and bones.

Even beyond the weight loss, though, I simply didn’t look healthy. As it subsequently turned out, the 2016 fast revealed the first signs that I was headed towards a health crisis. In short, I had been following a fully vegan diet which – although I loved the eco-friendly ideology of it – was not working for me on a physical level, especially while running 40 miles a week. Within another year or two I was suffering from acute protein deficiency, with a myriad of associated symptoms, including chronic joint pain and tendonitis, as well as adrenal fatigue. Thankfully, my wife figured out what was happening, and in 2019 I began my convalescence. However, precisely because of having followed a deficient diet with chronically low nutritional reserves for so long, this initially precluded the possibility of benefiting from longer fasts to heal from the physical repercussions and enduring injury of protein deficiency. In other words, I had fallen in between a rock and a hard place in terms of the relationship between nutrition and therapeutic fasting. Now, however, with six years having since passed, I certainly had built up enough reserves to go longer. And so, this 30-day fast was also always going to be about bringing closure to the whole period of protein deficiency since my 21-day fast back in 2016, as I aimed to heal the remaining damage.

It feels like coming home…

In a way this 30-day fast couldn’t have been a greater contrast with my first 21-day fast, a decade ago. This time it was so… comfortable. All the tension, the friction with the fast and myself were gone – again, a form of closure with the past. Back in 2016, I was engaged in a constant struggle with time. In fact, this remains my enduring memory of the whole fast, as I found myself relentlessly counting the days. Everyday. As much as I tried to let go and be in the moment (and it’s true I was in the moment sometimes), I just couldn’t soften into the full experience of the here and now. This manifested in my mind through fantasies about food: something which of course we all experience when fasting! Still, back then it did feel excessive – or at least certainly more than I would have wished. Here in 2025, however, my relationship with time has been so much more malleable. Yes, I was usually aware of what day I was on, but it really did feel like just another number. And a pretty random number at that. On a deeper level, though, numbers didn’t even matter. They really didn’t. They were abstract quantities with no real weight, no power over me. I was at peace: with time and with myself, now. Consequently, there was no need to fantasise about food, despite the fact that on this occasion I was living at home with my family, and constantly surrounded by the sights and smells of food at all times of the day. There was simply no temptation. Just a little curiosity.

Another huge difference between then and now – and one which I suspect was, in part, a driving force in the different psychological experiences of the two fasts – were energy levels. Back in 2016, they were suppressed and flattened to the extreme from the first few days of the fast. Any movement felt like a literal weight to be avoided. Here on my 30-day fast, though, I was weak but benefited from being more or less fully functional through most of the fast. I would spend time in the garden pruning or weeding, or go for small, slow walks. It was only as Day 21 approached that my energy levels began to bottom out (a phenomenon which I also observe in the majority of my clients: something I attribute to the adrenal healing which intensifies during this period). In terms of energy levels, my 2016 fast marked a turning point: with every fast since, both short and long, featuring notably higher levels of physical functionality. The only logical conclusion can be that I had benefited from an adrenal recalibration and healing, which had unlocked higher fasting energy levels from then on (again, a phenomenon which I likewise observe among those clients who undertake several fasts with me).

If, during my 2016 fast, I had struggled with low energy levels and an inability to let go, this manifested especially at night. As with so many other people, the deeper I went into the fast, the less I needed to sleep, and by the third week I was sleeping on average only 3-4 hours per night. My relationship with insomnia devolved into one of the biggest challenges of the fast. Tossing. Turning. Suffering with the inability to let go and surrender myself to sleep. One night I formulated the experience in its distilled form: that the deeper psychological function of sleep is ‘to escape from the self, from having to constantly live with the tiresome experience of one’s own ego.’ Perhaps true… Even too true. However, the healing and closure of my 30-day fast here in 2025 also birthed a new perspective. I followed a similar sleep pattern as last time, with dwindling sleep requirements, especially from the third week on. This time, though, my relationship with nocturnal life was altogether different. Yes, from time to time I would toss and turn, but more fundamentally I was at peace: at peace with the silence, with the openness expanse of the darkness – and with myself.

Peace with myself. A kind of homecoming. If there’s one overarching theme which characterises my relationship with this current 30-day fast, it’s precisely that. Perhaps it’s due to a decade’s worth of fasting in between these two milestones. Perhaps it’s also due to a decade’s worth of life having been lived. Probably both.

In the end, this wasn’t the fast I had envisaged or planned. If I’d hoped to benefit from the healing of slowing down, family life around me nevertheless continued to rage around me at full speed. (Unfortunately, my own work life didn’t slow down as much as I’d hoped it to either.) But inwardly the pace was different. I just had to tune into it. It brings to mind a recent conversation I had with Dr. Alan Goldhamer during a recent international online conference. He admitted he couldn’t even imagine fasting at home with family running around everywhere… What I realise now is that my 21-day fast back in 2016 took place in a bubble: a wonderful bubble on retreat in the depths of the countryside. For me to benefit from that first experience of a 3-week fast, it probably also had to be that way – and that’s okay. This time, in utter contrast, healing took place at home, which is precisely what has made this 30-day fast so much more real.

  1. Hi Tallis,
    I was so pleased (and both surprised & not surprised) to find your email & video link in my in-box. Perhaps only 1-3 hours prior, I’d decided it was time to reach out to you in a few days in preparation for my own coming (first) 21-day fast. And there you were, concluding your own 30 day fast! Thank you.

    As you do so well, your observations were beautifully insightful, articulate, and soulful. Congratulations on completing this fast! I was touched by how you layered your fast with the Summer Solstice. I also loved your languaging about your “relationship to the fast”, as I think of most things in terms of relationship.

    In any case, will be reaching out soon (after you’ve had some recovery). Until then, well-done on so many levels!
    Kindest wishes,
    Brian W.

  2. Wow, Tallis, that’s quite a story. Very inspiring. Maybe one day I’ll have enough in me to do a fast greater than 7 days. 30 days would be amazing though.

      Hi Adriana,
      Always good to hear from you, and I hope the summer is treating you well :-).
      I do hope the article inspired you, because you already have enough in you to go longer than 7 days. Yes, maybe, you’d need support, but that’s just a question of working out the details. You don’t need to be thinking about 30 days – and if I was skin and bones by the end, you certainly would be too LOL. But maybe to be entertaining the idea of 14?… It would go SO much deeper than the 7 days you’ve become accustomed to, and it would take healing to a whole new level. Maybe it’s worth a think?

      Hi Brian,
      Good to hear from you again, and thanks for writing :-).
      Well there we go again: synchronicity in fasting strikes again! It sounds like this is the right time to be looking towards 21 days, which would be a wonderful experience for you on so many levels. You’re definitely ready!
      Looking forward to hearing from you when YOU’RE ready – I’m pretty much all systems go already (except physically, of course, which will take a little longer to rebuild).
      Warmly,
      Tallis

  4. Quite interesting…..I got this email and link on the day I’d already planned to begin a fast of a week or so. I’m not sure if I’ll ever do one of similar length to my one of 26 days (2 years ago), but I’m certainly hooked on waterfasting as a super-important “habit” to be practiced one or a few times each year. Congrats on your accomplishment, Tallis, and heartfelt thanks for all the help and info you’ve provided to all of us! ♥

      Hi David,
      Thanks for writing!
      Well there you go: one of the things I didn’t mention in the article was the way that synchronicities have a very strange and sometimes eerie habit of popping up in fasts – and the longer the fast, usually the more powerful they tend be! It’s like the act of fasting is pulling you gravitionally towards the flow of the universe. Sorry to sound woo-woo here, but I’ve seen this stuff happen too many times to dismiss it simply as random nonsense from a blindly scientific point of view. Personally, I believe in both a random and a synchronistic universe intertwined and co-existing. The two don’t contradict each other. Just as science does not contradict faith.

      When fasting synchronicity strikes, this does NOT necessarily mean that on the surface level things look like a confirmation of your life resonating with the universe and Flow. In fact, sometimes the exact opposite is true. On Day 27 of my own fast, I had some shocking news slam into my day totally out of the blue from a former client from years ago. The more I sat with it, however, the more a could feel a deeper underlying connection with the undercurrents of my life, as well as with the whole theme of closure which this fast so much carried along with it. Without endings there are no beginnings.

      In your case, though, David, the meaning couldn’t be clearer: just fast!
      I wish you all success with it,
      Tallis

    I have crippled joints from Lymes disease and pain and exhaustion. Fasting is a miraculous way of releasing my body of the weight of both the physical and emotional. The last two fasts I’ve vomited continuously for days which is insurmountable. I have not as yet met anyone with enough experience or practical wisdom to be able to advise me how to over come this

      Hi Elisabeth
      Thanks for sharing. I’m sorry to hear about the chronic pain, but glad that at least you’ve found a way to alleviate symptoms through fasting. In terms of dealing with intense and/or chronic nausea, it’s one of the most difficult issues I tackle with clients as a fasting coach. It’s not easy, but expert supervision can definitely help.
      All the best,
      Tallis

      1. Dear Tallis,
        I really appreciated all the heart in your essay, and I could relate on so many levels. The recalibration, the surrender, the quiet beauty of a body finally being listened to. Every bit of it felt familiar. Thank you for sharing your story. Reading it helped me recognize and appreciate the shape of my own recent 30-day water fast with you.

        As you know, my second 30-day water fast began quietly but was quickly overtaken by unexpected upheaval in both my business and in my personal life. Physically, it was easier, as I’d already walked this road once and had learned my body’s rhythm, but emotionally, everything hit harder. By day 21,
        it felt like climbing a mountain while dodging falling rocks and trying to keep my footing, trying not to get knocked off course, but knowing I was going to reach the top no matter what tumbled down on me. I thrive when challenged, but I won’t pretend that the kind of challenges that arose during this fast weren’t incredibly hard. The timing made it all land heavier than usual.

        So much had come crashing down during those 30 days, I wasn’t sure I had gotten what I needed from the water fast. I have struggled to feel content with it. I had committed fully, but I still felt unfinished. Though something was still shifting inside me, even if I couldn’t name it yet.

        I couldn’t shake the feeling that I needed something big and grounded to help me process what I’d just been through, and that brought me back to a childhood fascination that never really left me.

        Ever since I was a kid I’ve been drawn to those massive earth-moving machines along the highways. I always wanted to be the one behind the controls, steering something powerful enough to shape the land itself.

        Then, weeks later after the fast, my husband rented a telehandler to move some equipment, and the opportunity for me to experience driving a big piece of equipment was mine for the taking!
        The telehandler isn’t an earth mover, but it’s probably the biggest piece of machinery I’ll ever get the chance to be around in this way.

        I used it to lift an old wooden wagon that has lived on our land for years. The wagon reminded me of Virginia, which I had left 6 years ago due to health issues, and hurriedly moved to Colorado, leaving everything behind. I’ve always felt bad that my family had to leave everything too, but at the time, it was what I felt I had to do health-wise to save my life. Anyway, I’d always believed the wagon was part of my new property’s history, but last summer I learned the truth: it had been bought at auction. That one detail quietly unraveled the bond I had with it.

        In the past few years, the climate here are n Colorado has changed. Spring rains and hail have been relentless. The wagon, once sturdy and proud, began to rot and sink. Its wood softened. The structure broke down. It could no longer hold its form. What had once stood as a symbol started to feel more like a burden. So I decided it was time to let it go.

        With the telehandler I raised the wagon high into the air, about 60 feet, equivalent to about six stories high. And then I took a breath and I dropped it. The crash was loud, but the moment was quiet. I started laughing very deeply, full-bodied laughter. I don’t think I’ve laughed like that in years. It wasn’t just the release of old wood hitting the dirt, it was something in me breaking loose too.

        The wagon had been sitting out front, sinking slowly into the earth, quietly carrying more than its own collapsing frame. It was a heavy load. It was not just steel and soaked wood, but pieces of the past. Like that wagon I had also been carrying a heavy load as well. And letting it crash to the ground felt like exhaling after holding my breath for years. It was release. It was grief. It was relief. It was finally letting go.

        I relate this to your mention of closure, I was able to have true closure not only on my past events but also closure on my water fast experience that I had held with high hope and expectations that I felt were not met, but which ultimately taught me something deeper. I couldn’t see it right away after my water fast, but the water fast did not only let me see that I had strength to endure, but also the capacity to let go, not by force, but by clarity. To stop dragging and let go of what no longer belongs. Even in the noise of life, with responsibilities and deadlines and people counting on me, that stillness, that exhale, of finishing the 30 days stayed with me. I don’t think I would have even considered my actions with the telehandler and wagon had it not been for the water fast teaching me that it’s okay to reach deep within and to feel the moment and then let it go if it no longer serves me.

        So thank you again for sharing. I’m so happy that you are able to do your fast at home. For me, I can’t imagine doing a long water fast anywhere but at home. In my home, I carried out my water fast mostly in my bedroom as it is my sanctuary. It’s my place of comfort, familiarity, and security. That comfort extends beyond the walls: it’s in the voices I hear downstairs or in the hallway, the rings and buzzes of devices that belong to others. These sounds remind me I’m not alone. My home is my safety net. On the hard days, it held me. On the easy days, it was familiarity. The comfort of my pets, the quiet reassurance that my family was just a whisper away. These things may not have erased the stress, but they softened it. And sometimes, that was enough.

        I know that while many of us go through similar aspects of a 30-day water fast and share some common experiences, each person is on their own healing journey as they move through emotional layers, both past and present, at different depths. Anyone who has completed a 30-day fast, or even longer, shares an unspoken bond. We understand the kind of inner strength it demands. The will to keep going when you just don’t think you can. I truly commend and respect anyone who’s done it, as
        it’s no simple task.

        Congratulations, Tallis,
        It takes real strength to move through life with presence, especially when it’s hard. The clarity and honesty in what you wrote speak to that strength. As you move forward, I hope you carry these moments with you
        as your finally able to complete your 30-day fast and realizing the deep closure it gave you on a decade of life. Here’s to gently stepping into what’s next, with a clearer heart and mind.

        Warmly,
        Samantha Hawes

          Hi Samantha,

          Thanks for sharing. It was truly, truly beautiful – and moving – to read.
          The image of the wagon… the telehandler… I do think, when we start to resonate with the ‘flow’ of the universe (through fasting or otherwise), that what is really happening is that we’re connecting our little, individual lives with deeper symbolic and universal patterns which exist, create and re-create through life like fractals CG Jung would call these ‘archetypes’. Those universal patterns support and nurture us

          Your wagon was such a powerful universal symbol. I love the way you describe that, in discovering the wagon’s false indentity, the relationship with your own inner wagon also began to rot and disintegrate – ultimately freeing you.

          Thank you so much again for sharing this, that others may also benefit from your experiences.
          ‘One for all, and all for one’…
