14–40 Day Water Fasts: Healing Power, Benefits & Risks

Why would anyone fast for two weeks—or more?
For those seeking the deepest levels of physical, emotional, or spiritual healing, a 14–40 day water fast may offer what shorter fasts cannot. Once your body has fully adapted to ketosis, longer fasts allow for profound detoxification, immune recalibration, trauma release, and sometimes even the reversal of chronic illness. However, they also require care, preparation, and guidance.

In this article, you’ll learn what happens in extended fasts, how to prepare and refeed, and how to distinguish between a true healing crisis and signs that it’s time to stop.

Note: Extended water fasts of 14–40 days are powerful but demanding. They should never be undertaken without expert supervision, especially if you have chronic health issues, take medications, or are unsure of your body’s limits. Always consult your doctor before beginning any prolonged fast. This article is for educational purposes only and does not replace medical advice or personalised coaching.

To address chronic illness, deep trauma, or long-standing toxic load—levels that shorter fasts usually can’t reach.

Yes—if done without guidance. Extended fasts can deplete fat, protein, or electrolytes if pushed too far.

A temporary flare-up of past symptoms as the body clears deeply stored illness. It can be intense but is often part of the healing.

If true hunger returns, or signs point to electrolyte imbalance, it’s time to break the fast safely.

Very slowly and intentionally, with light plant foods. The longer the fast, the longer the refeeding process should take.

Why in the world would you ever want to fast for two weeks or more?

If only a tiny percentage of people in the Western world ever undertake a water fast of any kind, then only a tiny percentage of people who water-fast will ever undertake an extended healing fast of 14 days or more. Why? There’s simply no need. For everyday cleansing and healing, occasional 7-10 day fasts combined with regular short fasts such as the 3-day or 36-hour water fast should keep you in excellent health.

Benefits of extended water fasts (14-40 days):

However, in order to reach the deepest possible level of healing and reap the greatest benefits, it is necessary to dig deeper with a longer fast. For instance, certain serious physical illnesses – those often deemed incurable by Western medicine – require the cleansing of an extended fast in order to permanently heal.

Despite what most modern medical doctors may tell you, conditions as wide and varied as Long Covid, gut issues (such as IBS, ulcerative colitis and food intolerances) adrenal issues (CFS/ME), diabetes, chronic high blood pressure, autoimmune disorders (including allergies and asthma), as well as certain types of tumors are all potentially curable. I know this for a fact, because I have personally worked with clients suffering from ALL the health issues listed above to the point of a full healing.

Dr Barker regularly speaks at international conferences on water fasting. Below you’ll find his lecture for The Real Truth About Health conference, as well as a panel conversation with Dr. Alan Goldhamer – one of the most recognised names in the field.

As a water fasting coach, I’m privileged to witness this miraculous healing potential of the human body every day! It does take time, though, and in order to heal effectively from chronic illness, the length of the fast must typically last 14-40 days.

In helping clients decide how long to fast, three main factors come into play.

First is the overall symptom picture – that is, the sum total of active health issues, all of which constitute a toxic load contributing to illness. Although, for example, someone may wish to fast in order to heal Long Covid, further questioning almost invariably reveals other health issues in the background, both past and present. Whether presenting with symptoms of their own or whether entirely sub-clinical and ‘invisible’, these apparently secondary issues tell a story of how, over the years, a client has arrived at the present moment.

The second factor which suggests how long a client may need to fast is the strength of their immune system. The primary factors here are age, diet, stress and, in the case of chronic illness, how much the immune system has already been worn down in fighting a war of attrition.

The third factor concerns the degree of prior cleansing – and especially water fasting. Quite simply, the more you’ve already fasted, the more quickly and powerfully your body can mobilise your immune system for healing.

Physical, emotional, spiritual healing:

Beyond physical healing, the deepest emotional and spiritual cleansing can similarly take place only through the sheer length of an extended fast. In fact, what I’ve seen over many years of coaching is that in order to achieve the greatest physical healing, it’s also necessary to surrender emotionally and spiritually to the whole process. A big part of my job is to help facilitate that process.

Although nowadays we tend to remember only the Biblical 40-day fasts of Moses and Jesus, the fact is that many spiritual traditions over the millennia have demanded 40-day water fasts. Even Pythagorus required potential students to undertake a 40-day fast before he was willing to accept them. As much as we balk at the idea of giving up food for such a long time, it’s mostly just a question of unwillingness to forgo the addictions and pleasures of life. Don’t believe the voice of your fears and reluctant ego. You won’t starve to death.

Unless you’re seriously malnourished and underweight to begin with, you carry the better part of 100,000 calories on you, locked in your fat tissue and waiting to be released through ketosis. That’s enough to last you well over 40 days. If you’re overweight, you could potentially fast for much longer (although in most cases this is not advisable).

In other words, getting through a 14, 21 or 40-day fast is often a mind game more than anything.

Letting go of your fears about fasting is just the beginning. The process of surrender also eventually leads to the release of pent-up, self-destructive emotions and, for some people, a catharsis of trauma from the distant past. In doing so, you’ll free yourself: discovering a place of inner calm and spaciousness where you can finally breathe. This is a hugely important part of the healing process.

The webshop offers downloadable fasting plans and guides to help make your water fast a success.

Experiencing a healing crisis:

Although in one respect an extended fast simply continues the notion of a 7-10 day water fast, it is also much more powerful because it gives you the opportunity to experience deeper ‘healing crises‘. As described in the article on the 7-10 day water fast, a healing crisis often occurs towards the end of the first week of water fasting, as the symptoms of old illnesses, injuries and traumas resurface, before being permanently expelled from your body.

A similar process often occurs around the end of the second week of fasting – and this is the reason that if you decide to extend a 7-10 day water fast, it’s worth aiming for at least 14 days. This second healing crisis tends to call forth deeper issues than the first healing crisis, or, alternatively, finishes resolving those issues which were not fully cleared during the first healing crisis. In other words, it’s from the beginning of the second week of water fasting that your body can begin to heal from more serious health issues. Simply, up until this point, your body has been focussed on cleansing the toxins of everyday life (and especially so if you haven’t been fasting regularly).

For the deepest and most serious health issues, healing crises often occur much later into the fast, whether 20, 30 or even 40 days. There’s no way to accurately predict when they will occur. You can only trust your body and let nature take its course…

Occasionally, healing crises can be extremely intense, especially when they occur late into a fast. When this happens, it’s critically important to be able to tell the difference between a healing crisis and a sign from your body urging you to stop the fast. This is where working with an experienced water fasting coach can really help. If it’s a healing crisis, you should ideally try and push through. If it’s not, you should stop immediately! (continues below)

Not every healing process is accompanied by a dramatic healing crisis. Sometimes symptoms of illness and trauma simply begin to disappear. In cases like this – when no clear sign indicates that you’ve obviously freed yourself from a health issue – it can be difficult to know when to end the fast. This is another reason why it’s advisable to consider undertaking an extended fast with the help of an expert who understands the subtleties and symptomatology of fasting. The other main reason for working with a professional is to make sure you don’t overstep your body’s nutritional capabilities, as a prolonged fast begins to reach its physical limits.

ONLINE COURSE

Complete a 3-day water fast

This video + pdf bundle provides you with all you need to know in order to safely, successfully and smoothly carry out your first 3-day water fast. If you already have a little experience, there are plenty of additional tips to help you go deeper into water fasting.

The dangers of fasting too long:

  • Depletion of fat (adipose tissue)
  • Depletion of protein (amino acids from muscle tissue)
  • Depletion of electrolytes

If you continue fasting indefinitely there comes a point where the fast turns into starvation. You obviously don’t want to overstep this mark! For when your fat stores are finally depleted, the body has no choice other than to devour muscle tissue, as well as feed from your inner organs. You’ll do yourself serious damage. Fortunately, though, the body sends a clear sign: extreme hunger. Although it’s unlikely you’ll miss this red flag, it’s also true that normal periods of hunger can develop during an extended fast. The urban myth out there on the internet – that hunger simply disappears on the third day – is a gross oversimplification of what actually happens. On longer fasts, it isn’t uncommon for my clients to believe that ‘true hunger has returned’, and that they should break their fasts. Usually (but not always), this phenomenon simply constitutes a totally normal physiological phase of the fast, or – even more likely – their digestive juices are being driven by an increasing emotional desire to eat. Without someone offering an objective mirror on the outside, it can be extremely difficult to distinguish between the different possible scenarios!

In addition, two other less obvious scenarios demand the end of a fast. The first possibility is that you run out of amino acids (derived from muscle tissue) before you deplete your fat stores. In order to power your body as a whole, it’s true that ketosis is extremely efficient. The problem is that the brain demands another fuel entirely: glucose. And this cannot easily be metabolised from fat tissue. Instead, the body must extract it by breaking down proteins in a process called gluconeogenesis (described in greater detail in my article on the 3-day fast). However, the actual danger of depleting amino acids before fat tissue is largely theoretical. I have never witnessed this happen myself, and it is only likely to arise on fasts longer than 40 days in the case of someone who is morbidly obese with severely atrophied muscle tissue.

The final possibility is certainly a real danger: the depletion of electrolytes (blood salts), especially potassium or sodium. Although unlikely, this process is potentially life-threatening! Understandably, many people decide to take electrolytes while fasting, precisely in order to avoid this scenario. If the sole reason for fasting is to lose weight, then by all means do so! However, if you are fasting because of a chronic health issue, it is critically important to understand that taking electrolytes during a water fast compromises both the deepest cleansing and healing – as I have observed clinically among clients who choose to fast using electrolyte supplementation. (I will delve into the physiology of this in a future article.) Although the danger of electrolyte imbalance usually increases from only about the 21-day mark, it is extremely important to respond to the first warning signs if and when they do arise. Unfortunately, this is difficult to the untrained eye, because the symptoms of potassium and sodium depletion overlap with other totally normal detox symptoms. The key is in understanding the context as well as the overall, underlying symptom picture.

Refeeding:

After you break an extended fast, it’s extremely important to follow a well structured meal plan. In an ideal world, this should be tailor-made to the individual person, based on prior nutritional reserves, any dietary sensitivities, as well as the given health issue for which someone has fasted. When this is not possible, a comprehensive pdf on refeeding can be found in the webshop here:

How to break a water fast?

If you return too quickly to a normal diet, you risk encountering both digestive problems as well as ‘refeeding syndrome’. This is a potentially fatal complication caused by the change from ketosis back to your everyday metabolism. If you have any doubts, I offer a downloadable 86-page PDF which covers refeeding for any length of fast.

  1. Hi Tallis,
    I am on day 14 of my water fast and I am feeling very weak. I was not overweight to begin with and I am very skinny now. I feel mentally very very clear.. emotionally still processing a lot of anger. I have auto immune issues and have previously had cancer and chemotherapy (8 years ago). I am waiting for my tongue to turn pink and the white mucus to disappear. My tongue is getting pinker each day but isn’t quite fully pink yet. A little bit of fear is creeping in because I feel so weak and am very skinny and I don’t want to harm myself. I have prepared irish sea moss and was going to start with a teaspoon of that a day and I have started drinking a cup of chaga mushroom tea since yesterday, Are there any other vital signs from my body I can watch for to know when to break the fast. I was going to break the fast with some bone broth and watered down fresh tomato juice, Are they wise choices in your thinking?
    Kind regards

      Hi Ellie,
      Apologies for the delay in responding. There’s been a glitch with messaging on the website.
      It’s hard to comment on general signs about when to stop a fast… The first ‘classic’ sign is that hunger returns. I’ve never seen a client reach this point, although normal hunger can arise at any point during a fast. The second ‘classic’ sign is that the tongue turns completely pink. I’ve never seen a client reach this point either, although the tongue can and does change in its colouring during a fast. Having said this, there are definitely times when I’ve advised a client to stop a fast, but this has always been based on the individual circumstances of the client and the fast. If you’re ‘very skinny’ it’s hard to say more here without knowing your height and weight.
      Your plan to break the fast can certainly work.
      All the best,
      Tallis

  2. thank you for your time and effort supporting all of us. Do you take concern or issue with enemas during fasting. MMS or coffee?

      Tallis Barker, D.Phil.

      Hi Melisa,
      Thanks for writing. There are those who say you should never take an enema while there are those who prescribe daily enemas. I prefer a middle road, in which you take an enema if there are concrete signs of a build-up of toxicity in the colon. Otherwise, “if the wheel ain’t broken, don’t fix it.” When an enema is necessary during a fast, it should always be with plain water. Coffee enemas are far too strong on your liver, which is already working full power on detox. I’ve had numerous clients who have ended up with severe cramping because they’ve followed misguided advice about coffee enemas…
      Hope this helps,
      Tallis

  3. Hi Tallis,

    I am going into Day 10 of my water fast, and tomorrow morning will complete my first 36 hour dry fast.

    In 2020 I completed a 40 (and a half!) day water fast, which went very well, in great part thanks to your website and your re-feeding booklet.

    I have several questions:

    • How much water do you recommend I drink per day?
    (I know I’ve read this on our website somewhere but can’t find it!)

    I’ve been getting acid reflux, mostly in the evenings (after drinking1/4 cup). I’ve not been diligent in keeping a record of what I drink, but it started off at around 1.8l and has reduced during the fast, as has my desire to drink. The day before my dry fast I drank around 800ml, which is the lowest it has been, and seems too low. That day I had some acid reflux in the morning, after drinking.

    The acid reflux is quite temporary.

    When I start drinking tomorrow, I feel I should make a point of sipping little, but often.
    • Do you agree with this?

    • Do you have any tips for dealing with acid reflux?

    Thank you so much!

      Hi Tanya,

      Congratulations on your first 36-hour dry fast – not to mention the 40 days on water 🙂
      When you finish a dry fast, it’s always a good idea to sip at least the first pint (500ml) or so. You don’t want to shock your system in a manner similar to finishing a water fast with a large meal! This leads to answering your other question: during a water fast it’s almost always best to drink to thirst. You may be surprised how little water you actually need after a dry fast – in the same way that people don’t get ravenously hungry after a water fast. I’m absolutely not suggesting that you should limit water intake here, just that you should really try to feel into what your BODY wants rather than what your MIND may be dictating about how much you ‘should’ drink following the dry fast.

      When it comes to acid reflux, there are multiple possible causes which make it difficult to go into here. With my clients, it’s the kind of thing we cover in daily coaching sessions, first identifying the cause and then finding a solution. Hopefully, your dry fast will have resolved the issue.

      All the best,
      Tallis

      1. Hi Tallis,

        Thank you so much for your prompt response!

        What you say here, really resonates: “you should really try to feel into what your BODY wants rather than what your MIND may be dictating”.

        I felt that my body was leading me towards a dry fast, as I did not feel like drinking. I wondered whether this would result in a “reset” that then allowed me to drink (more) with ease. So far, this is what is happening.

        I completed my 37h dry fast at 8am, and it is going well. I am drinking regularly and it feels good! I’m thirsty and feel like drinking again! No acid reflux. (I made a point this time round being mindful of my pre-fast meals and the last three days were liquid, to avoid food remnants as much as possible.)

        Fingers crossed, as you said, the dry fast seems to have resolved this issue. I love how your words align with my intuition/body listening-to.

        My question about water intake was about during a water fast (as opposed to after a dry fast). I’m sorry if my wording was confusing!

        – Is there a minimum amount of water I should be drinking?

        Thanks again for al that you do!

        Warmest wishes,

        Tanya

          Hi again Tanya,
          Actually, my previous answer applies here too: it’s almost always best to drink to thirst. In terms of a minimum amount to drink, there’s no fixed limit – it really depends on different people at different times in different climates, at different points in the detoxing cycle. If you had to put an absolute limit on it, though, I’d say that you need to drink at least a litre per day in order to prevent dehydration from setting in over the long term.
          Glad your reflux is gone!
          Keep listening to your body – it knows what’s best 🙂
          Tallis

          1. Hi Tallis, 



            It’s been 6 days now, and I continue to feel natural thirst and drink happily and easily.


            
Thank you so much for your responses and for answering my questions. Much appreciated!



            Here’s to listening to my body. 😊

            

Have a lovely day!

  4. Hi, great insights! Thanks.

    Context:
    I’m currently trancing the 6th day of a water fast (plus pink salt, green tea and black coffee, which I ditched on day 5 as I realized it put my gut to work.)
    Since yesterday I started feeling mild pain in every part of the body that had ever been injured/infected. (left lower back, right sciatic nerve/muscle, etc.). I assume it’s a healing crisis.

    Question:
    When is best to end the fast? Would I ruin the process if I end it today/tomorrow (6/7d)?
    Given that I already had a “crisis” how necessary is it to push another week or longer?

    1. Tallis Barker, D.Phil. Avatar
      Tallis Barker, D.Phil.

      Hi Juan,

      Thanks for sharing. I’m glad you realised that black coffee is definitely a problem on extended fasts – in contrast to what some doctors who are well known for intermittent fasting (but who unfortunately don’t have much experience in prolonged fasts) have publicised…

      The kinds of pains you describe do sound like a healing crisis. By the way, next time you fast do NOT take salt if you want to maximise healing. Salt increases inflammation, which interferes with the healing process. Again, I don’t want to name names, but there are certain well known doctors who don’t recognise this, because they are acquainted only with shorter fasts in which salt intake doesn’t make much difference.

      To answer your question, the best time to end a fast is when you’re not in the middle of a healing crisis. This might mean waiting a day or two until the current cycle has finished. But you should also know that, depending on their severity, many injuries and health issues require several healing crises in order to reach full healing – and this would require you to extend the fast considerably longer. Whether it’s worth extending your current fast, or whether you want to pick up where you left off on a later fast is your choice!

      All the best,
      Tallis

    2. Hello, I’m on day 11 of a 21 day fast, and my ketones today were 300 mg/dl (16.6 mmol/l), which seems high. But my glucose is hanging out in the 80-95 range. I had the crisis on day 6 (holy crow) but now I feel great and alert albeit weak. Should I worry about those high ketones? I’m not ready to stop.

      1. Tallis Barker, D.Phil. Avatar
        Tallis Barker, D.Phil.

        Hi Alison,
        Thanks for sharing. Those are pretty high ketone levels. Most people stabilise at about 5-6+ mmol/l – so you’re well above that. Are you sure you’re getting accurate readings? If you feel great, it’s unlikely that anything too harmful is taking place (weakness is normal), but it might be a good idea to get a reading from an alternative device.
        All the best,

  6. Hey, I am doing a 30-40 day water fast. Is consuming lemon water with the lemon seeds going to negate the fast? Or will I still experience deep healing? I have a feeling the lemon and lemon seeds will only improve the quality of healing.

    1. Tallis Barker, D.Phil. Avatar
      Tallis Barker, D.Phil.

      Hi Austin,
      It all boils down to calories. I assume by ‘lemon water’ you’re not referring to lemonade :-).
      About the lemon seeds: I’m doubtful about their improving the quality of healing. They only give your digestive system something to think about, and as you get further into the fast, this is going to increase the likelihood of acid reflux. More importantly, if you want to get toxins OUT of your system, it’s best not to put anything INTO it – or to put it more technically: anabolic and catabolic states are mutually exclusive. (This applies to both the lemon water and the seeds.)
      Hope this helps,
      Tallis

  7. Hello! I am currently doing a water fast to detox and heal my body. I am overweight so is it safe for me to prolong the fast past 10-14 safely? I do not work outside the home. I do walk and do Pilates for exercise. I have been gentle with the Pilates and walking. Not pushing any of it. Just moving and stretching my body.
    Also how would I know if my body is ready for me to stop fasting. How long do you usually recommend someone fast if they are working on healing their body. I don’t want to stop too soon.
    Thank you!

      Hi Denise,
      Thanks for writing. These are important and complex questions! First, assuming that you’ve followed all the advice here on this website, it’s almost certainly safe for you to safely extend beyond 10-14 days. It’s really only once you’re well past 21 days that more serious issues might arise – and even here this occurs only rarely. It’s a question of learning to read the signs and symptoms that your body might want you to stop fasting, but, again, I very rarely see this among my clients. It’s almost always the mind which demands an end to the fast before the body!
      In terms of how long to fast in order to heal, there’s no easy answer. It will depend on the particular type of issue, the severity of the issue, as well as the strength of your immune system and the toxic load already carried by your body at the beginning of the fast.
      Hope this helps,

  8. I must work a physically demanding job. Any insight on 14 to 21 day fast and so.e heavy lifting. On feet all day. Breaking a sweat. Thank you for your work

    1. Tallis Barker, D.Phil. Avatar
      Tallis Barker, D.Phil.

      Hi Jason,

      Thanks for sharing. I think you’ll find it pretty tough – if not impossible – to carry out an extended fast while doing a demanding physical job. The problem is that your body will be running on the fuel provided by fatty acids, which requires a 100% aerobic burn (metabolism which creates energy through burning oxygen). Unlike carbs, which can be burnt in either an aerobic or anaerobic environment, this means that any activity which would normally get you into so-called ‘oxygen debt’ is going to be impossible.

      In everyday life, the experience of oxygen debt involves heavy breathing after completing an activity, in order to re-oxygenate the blood. (More technically, you’re breathing heavily after the activity in order to return the build-up of lactic acid back into pyruvic acid.) If you’re breaking a sweat doing your current job, there’s no question in my mind that you’re running into oxygen debt.

      In contrast, the 100% aerobic burn of ketosis means that you can burn only what you’re able to provide oxygen for in real time. This is the level of activity normally associated with walking or low-stress activities. I’m afraid that’s going to limit what you can do while working.

      Hope this helps,
      Tallis

      1. perfect response. Thank you!
        Today is day 4 of the water fast. I hired a helper to do the heavy lifting and was able to not have heavy breathing or break a sweat at all. I really took it easy at work. I think I will stop at 7 days because next weeks work will be harder.
        I plan to stop this work and transition to working from home from the computer. Maybe then I will aim for a longer healing fast when I can rest and meditate and light stretching.
        I will seek your advice and possibly coaching when that time comes.
        thanks again for taking the time to respond so thoroughly.

          Glad things have worked out for you like this! It’s definitely a good idea to stop at 7 days if next week will be more demanding. These 7 days won’t have been wasted, though, even if originally you’d hoped for a longer fast. It means your body will be able to dive in quicker next time to do some intensive cleansing – and you’ve already made a good start on the detox this time around anyway.
          Tallis

  9. Your article was very interesting and informative. My question is, I have heard of juice fasting which still has calories so I am not much interested in that but what happens if you drink non caloric drinks like broths or diet soda? Will healing still occur with those items entering my body? I was dx with DM ll recently and would like to work on that. Thanks

      Tallis Barker, D.Phil.

      Hi Cindy,

      Glad you enjoyed the article. If you’re fasting in order to heal and cleanse, then there’s no question that the best thing for you is a water-only fast. Broths do have calories, albeit minimal, which will lower the efficacy of the fast to a degree. They can also contain salt, which will work against the anti-inflammatory effects of a water-only fast. The problem with diet sodas is that they’re often highly acidic, and this compounds the build-up of acids which already takes place through cleansing. This is likely to exacerbate detox symptoms. On top of that, the bubbles in soda (in addition to being acidic) often end up over-stimulating the stomach, which leads to the production of stomach acid and reflux.

      If water feels too ‘boring’, you might consider adding occasional non-caffeinated herbal teas instead. These don’t adversely impact on the efficacy of a healing fast.

      Hope this helps,

  10. Thank you so much for all your help on this site!
    My question is this, I have been doing the Atkins diet (exclusively the induction phase of the diet) off and on for 24 years and I would like to know if I can break my 14 day fast with some creamy scrambled eggs? I would like to stay away from all carbohydrates if I can, so I can continue my ketosis after my fast is over. I have lost 20 lbs so far on this fast, but I really need to loose another 30 lbs, at least.This is my third water only fast in the last year, (3, 5 , and now 14 day fasts) today I am on day 10. I value your opinion in this matter…
    Thanks again for all your help!

      Hi Greg,
      Thanks for your question. It’s never a good idea to break an extended fast on animal protein! Too many digestive enzymes are required after your digestion has been in hibernation for so long. You might get away with it, but more likely it will sit in your stomach as you struggle to digest it.
      It’s much better to focus on fruits and vegetables at the beginning of any refeeding process, regardless of what diet you plan on ending up on. You don’t need to worry about getting temporarily out of ketosis because you’re already fat-adapted from being on Atkins – and especially from having fasted for two weeks!
      All the best,
      Tallis

  11. Well I was pushing for 40 days but my ND felt I needed to start back with receding due to my intense fatigue along with MS diagnosis. I feel a lot better on my plant based diet, getting used to new things this year.

  12. Dr. Tallis,

    Thanks for all the information provided on fasting. It gives me great hope as I continue my 40 day fast. I have undergone one week already and feel confident as I read these inspiring posts. God bless you
