7-10 day water fasts: maximising benefits and overcoming challenges

Expert Water fasting coaching with Dr Tallis Barker? D.Phil, Nat.Dip

Once you’ve gained confidence with 3-day fasts, a 7–10 day water fast offers an entirely different level of healing. This is when your body not only burns fat through ketosis, but begins to detoxify stored toxins, release inflammation, and activate deeper repair mechanisms. It’s not always easy—but it’s often where the most profound shifts take place, physically, emotionally, and spiritually.

In this article, you’ll learn what to expect at each stage of a 7–10 day fast, how to prepare and refeed safely, and how to recognise signs of deeper healing—including what’s known as a healing crisis. If you’re planning your first longer fast, this is your guide.

It allows the body to go beyond ketosis and into deeper detox, cellular repair, and long-term healing.

Not always. Many people find the first 3 days are the hardest, and the rest becomes easier as ketosis stabilises.

Lighten your diet with fruits and vegetables to support digestion and ease the transition into fasting.

It’s a temporary return or intensification of old symptoms as your body clears deep-rooted issues.

Very gently—with juice or light fruit/vegetables. Refeeding should be slow and respectful to your digestion.

Introduction:

Assuming you don’t have any urgent health issues which require an immediate extended fast (typically lasting 14-40 days), then I believe the best way to establish a long-term relationship with water fasting is to develop and nurture that relationship gradually. The most reliable way to do this is to work initially with short fasts which feel relatively manageable, without putting undue pressure on yourself.

After you feel comfortable with 3 day water fasts and, physically, your body can make the switch to ketosis without much fuss, then it’s time to consider a 7-10 day water fast. For it’s only after you begin drawing solely on the energy of fat cells that the process of detoxification can kick into a higher gear (more info here) and you can start to reap the greatest benefits of a water fast. This means that a 3 day fast simply isn’t enough to confront any deeper issues you might want to heal.

If you’ve found it difficult to get through your first few three-day water fasts, it’s only understandable that the thought of a 7-10 day fast seems even more daunting. For this reason, I offer private online consultations and coaching for water fasting.

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.

What happens during a 7-10 day water fast?

Despite some natural doubts and fears, many of my clients find that 7-10 day fasts tend to go more smoothly than they first expect (so long as they’re basically healthy and don’t have any serious issues with detox). This is because your body does some of the hardest work in the first three days while it establishes ketosis – and during which your fuel tanks are also running on empty. From the third day on, though, ketosis continues to become increasingly efficient, and this typically leads to one of two outcomes.

On the one hand, some people begin to feel lighter and fuller with energy. In many ways, the fast can feel like a celebration of freedom from the daily need to eat food. This freedom, as well as a lighter body and clearer consciousness, can feel so good that many people actually experience a sense of reluctance in returning to food at the end of the fast. There really is a beautiful purity about just being, without the needs and addictions of food distracting you, weighing you down.

On the other hand, some people experience a distinct roller coaster ride from this point as detox symptoms ebb and flow. In essence, with your ketosis engine having powered up over the first three days, your body now wants to turn all of that energy towards detox and healing, which can actually lead to lower perceived energy levels. It’s important to remember that you’re not actually lacking in overall energy, but rather that energy wants to flow inwards instead of outwards like it does in everyday life. Don’t get disheartened: as hard as it often is, this means your body is working for you!

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

As your healing metabolism firmly establishes itself by the end of the third day, the digestive system is in the midst of shutting down its normal function. As a result, most hunger pangs usually subside significantly after this point, assuming you’re able to rest and not overextend yourself with too much work. When I’m working with a client, one of the most frequent conversations is the need to try and slow down the pace of everyday life, both in order to maximise healing as well as to minimise any remaining hunger pangs. This doesn’t necessarily mean you need to give up your job and spend the whole day in bed (!), but it does mean that it’s a good idea to try and reduce your commitments during the fast. Remember: your fast should be about you and not trying to pretend it’s ‘just another day’ of your regular routine.

This is all the more important if you’re fasting in order to address a health problem. Your body has a finite amount of energy, and it’s simply not worth wasting too much of that energy on the activities of everyday life. One of the most important issues I discuss with clients is how to best manage daily activities in order to maximise the healing potential of a fast, when it isn’t possible to take time off from work. The reality is that we often don’t live in an ideal world – and the sooner this is recognised, the more effectively it becomes possible to devise alternative strategies.

Dietary preparation before a 7-10 day fast:

Given that digestion comes to a halt after a few days of fasting, it’s extremely important to consider how and what you eat in the transition period both before and after any fast longer than three days. The transition before a fast is important because you don’t want your digestive system to shut down with food still remaining inside the intestines. This is important for two reasons.

First, it can rot inside you. Not a pretty thought. And as it rots, the toxic by-products aren’t going to help your body – precisely when you’re trying to detoxify through the fast itself.

Second, during the most intense periods of detox, your liver is often forced to release semi-processed toxins into the bile, which then leads to a potential toxic build-up in the colon. You don’t want to complicate matters further by having any digestive remnants hanging around as well!

Practically, dietary preparation means gradually lightening up your diet in the days before a 7-10 day fast. This means different things to different people, depending on their specific diet. Exactly how to carry out a dietary preparation is something I discuss with each client on an individual basis. However, one common element involves increasing relative fruit and/or vegetable intake. Where this is contraindicated because of food sensitivities or gut issues such as SIBO, it is extremely important to find an alternative strategy.

There are several benefits of focussing on fruits and vegetables before a 7-10 day fast. First, they require less energy to digest. This allows your body to wind down digestion and switch into its healing metabolism more quickly and effectively. Second, they contain plenty of fibre to help elimination, thereby clearing out digestive remnants before peristalsis (motility) largely ceases during the fast. Third, they are so-called ‘alkaline-forming’ foods. This helps to balance the pH of your body during the fast, especially during the heaviest periods of fasting detox.

Refeeding after a 7-10 day fast:

The transition out of a 7-10 day fast is at least as important as the preparation beforehand, because your digestive system is hibernating. It can’t digest. You have to wake it up slowly and with respect, eating small portions of easily digestible foods. Otherwise, you’ll be sorry!

Just as any food remaining in the gut at the beginning of a longer fast can rot, so a similar situation can occur now too. Anything other than the simplest fruits and vegetables is likely to sit in your stomach, until your digestive system is able to cope. This can and will take days. After fasting, many of my clients find that the transition time back to normal eating with a normal appetite can last up to a similar length of time as that of the fast itself (although there is also a large degree of variation from person to person, and many people bounce back more quickly).

In essence, a refeeding strategy should look the mirror image of what happens during the dietary preparation before the fast (see above). The exact pacing of refeeding, however, should be dictated by the body itself, rather than by emotional cravings for particular foods or simply a driving desire to eat. Until gaining enough experience in fasting, most people find this exceedingly difficult – and, consequently, managing issues during refeeding is one of the most important elements of my work when coaching most clients.

I remember the exuberance of celebrating the end of my own first 7 day water fast. I had no idea what I was doing! A simple salad quickly become a slice of pizza – which then turned into eating the whole pizza!!! It weighed like an anchor in my stomach for literally days afterwards… Needless to say, I learned my lesson afterwards!

To help people deal with the trials and tribulations of refeeding, I offer an exhaustive pdf on the subject in the webshop:

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.

The 7-10 day water fast in greater detail:

Days 1-3:

Of course, the first three days of a 7-10 day water fast generally follow the process described in the 3 day water fast. With experience, though, it will become much easier – even enjoyable – and the process to complete the switch to ketosis will accelerate.

Days 4-6:

Days 4-6 is the usual timeframe when your body reaches maximum ketosis. This is clearly supported by my clients who love data, and who choose to measure their daily blood ketone levels. With a remarkable degree of consistency, most of them reach an average maximum ketosis of 5-6 mmol/l, usually around Day 5 (+/- 1 day).

At this point, after having fully ramped up ketosis, your body will want to devote greater resources to detox and healing. You’ll know when this happens! Above and beyond the detox symptoms mentioned above, your breath will stink. Your sweat and general body odour will also stink, as your skin releases toxins which may have been locked up inside you for literally most of your life. No, it’s not a very social occupation! But directly experiencing the repulsive things coming out of your body can make you appreciate how good it is to be free of them! It will give you the willpower to continue fasting in the future, no matter how hard it may have been in the beginning. I myself became a convert to water fasting on Day 4 or 5 of my first 7-day water fast, when my tongue began to produce a foul metallic-tasting froth. It tasted literally like poison.

Beyond the possibility of nausea at any time, detox can also typically cause aches in the muscles, connective tissue and the lymphatic system. However, this is generally more bearable than during the first three days, when you’re lower on energy. You’ll probably find there are periods when physically you actually feel great, with a clear and still consciousness, and then this will pass into a period of deeper cleansing when you feel weaker and heavier. During longer fasts, things always change. From hour to hour. From day to day. There’s no apparent logic to it, so don’t try to analyse. Just trust your body and go with the flow. It knows what it’s doing: how and what to detox, where to heal, and when to take breaks in between these more intensive periods.

Days 7-10:

You might be wondering why I’ve not listed a ‘5 day water fast’ or something similar here on this website. If you’d like to try four or five days, then by all means do! Every day of fasting does you good! But it’s because of the benefits of what often happens around the end of the first week of fasting that, in my opinion, it’s worth aiming for a period of 7-10 days. It’s at this point that you may experience a so-called ‘healing crisis‘. This occurs when your body has moved beyond the simple ‘house-cleaning’ of everyday toxins, and has started to tackle deeper illnesses, injuries and traumas (both physical and emotional). This is also described in the article on extended 14-40 day fasts.

What is a healing crisis?

A healing crisis consists of symptoms of an (old) illness returning or temporarily intensifying during the fast itself. This can be a little worrying, especially if you don’t understand what’s happening to you at the time. Nevertheless, it is perfectly normal. Think of it like this: fasting calls the illness forth from where it is otherwise locked physically into the depths of your body and/or emotionally into your subconscious. In calling it forth, you may temporarily experience the symptoms of the illness more acutely, but it is precisely through shaking it loose that you are then able to permanently expel the illness and truly heal. Western medicine can hardly ever achieve this to the same degree, because toxic (allopathic) drugs and physical procedures tend only to reduce or suppress symptoms. They do not deal with root causes of illness!

Occasionally, healing crises can be extremely intense. 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 fasting coach like myself can really help. If it’s a healing crisis, you should ideally try and push through. If it’s not, you should stop immediately!

What about water fasts longer than 7-10 days?

Given the degree of detox and depth of healing which occurs during a 7-10 day water fast, there’s usually no need to contemplate longer fasts unless you’d like to address a serious health issue or unless you feel the need to go deeper into your being spiritually. A weekly 24- or 36-hour fast (or perhaps regular intermittent fasting instead) combined with an occasional 7-10 day fast should be all that’s necessary in order to preserve good health. Exactly how frequently you conduct a 7-10 day fast is up to you, but please don’t violate your body by fasting before it’s ready – even if your rational mind believes it’s for a good cause.

Once you’ve faced and overcome the basic physical and emotional challenges on shorter 1-3 day water fasts, you can begin to trust your body and what it wants. At this point, your body always knows best. When the time is right, you’ll feel an inner urge welling up inside yourself to do a 7-10 day fast. You’ll look forward to it. For some people this may be only once every few years, for others up to a couple of times per year. Just follow your inner calling, and let the fast come to you – rather than the other way around!

  1. What about a small amount of black coffee on a water fast? Just started a water fast and found your site, thank you for all of the great information.

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

      Hi,
      A small amount of black coffee isn’t going to make much difference on 24- or 36-hour fasts. For anything longer than that, it starts causing problems for most people. Acid reflux is much more likely. The acids in the coffee also tend to stimulate digestive juices and hunger (although over the first day or two the caffeine can initially reduce it). The caffeine also works against the healing potential of the fast, since this drug stimulates your body towards a faster metabolism – when precisely the opposite should be taking place. It also raises blood pressure, when precisely the opposite should be taking place in order to help the cells cleanse most efficiently.
      You get the idea 🙂
      Tallis

      1. You are exactly right, as usual! I also heard black coffee was ok, but it made my last fast the worst experience. The reflux was horrific and the reason I stopped my fast after only 5 days. Also noticed my BP didn’t go down as usual. Never again; it’s water only from now on.

          Hi Pam,
          Sorry to hear about your own experience with black coffee. There really is a lot of unreliable information on the internet – some of it even published by doctors (one or two are quite well known…) who claim to know about fasting. What they don’t understand is that some of the principles which do work with intermittent fasting definitely do NOT work when applied to longer fasts!
          Yes, water only from now on 🙂

  2. I just finished day three of water fast but apparently, I did not start this out right, I dove in after several indulgent days leading up to it. Is there any way to continue the fast and cleanse my body of the food that is probably “rotting“ in my body? Ewwww…
    Just an FYI I did a 14 day water fast several years ago… and it was an amazing experience. This is not my first one.

      Hi Lisa,
      Thanks for writing. A lot depends on you and your digestion. I once had a client who started a 40-day water fast after having had a steak (!), and they managed just fine. Of course, this is the exception and not the rule, but it all depends on how your body eliminates the food of those ‘indulgent days’ before your fast. One option would be to do an enema to flush out whatever remains. Another would be to continue and see where it takes you. There’s no clear-cut answer here!

  3. Thank you for this article. I’ve done a couple of 7 day water fasts in the past mostly for spiritual reasons. Now i’d like to do it for healing. Have you ever heard of fasting for allergies? I just have been diagnosed with allergies and allergies induced Ashma. My first thought was that I need to fast!

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

      Hi Ginger,
      Thanks for your question. I’ve worked with numerous clients for whom healing allergies is either their primary or secondary goal. – And yes, fasting can be very effective in this respect! Although allergies will often temporarily improve during shorter fasts, you’d usually want to aim for around 21 days in order to start effecting permanent change. It may be worth looking at your post-fasting diet too. If that sounds too daunting to manage alone, you can find me on the coaching page :-).
      All the best,

  4. Hello Tallis,

    I finished my 7 days water only fast. It felt good.

    Then I consumed: Orange and apple juice + 5 solid red apple.

    After 4 hours later I drunk tomatoe and vegetable soup (contains little bit oil and little bit salt)

    Will I die of refeeding syndrome?

      Tallis Barker, D.Phil.

      Hi Mert,
      Refeeding syndrome is really only a potential issue on longer fasts, usually from around 14+ days. Maybe you overdid it with the apples, but you’ll certainly survive! (And at least you focussed on fruits and vegetables, and not heavier food groups.)

    Hello Dr. Barker,
    I’m interested in doing a 21-day water fast and wondered how you go about supporting me throughout. I’m not worried about the physical part of the fast but know that it quickly becomes a ‘mental’ game. I’ve fasted several times before – the longest being a 9-day water fast (with some light herbal teas and a little light black coffee) but 21 days is a bit daunting when one is alone.

  6. Hey Dr Barker, I’m thankful I found your site. I’ve got some health issues that I want to see if fasting will help expel. Well I jumped in with both feet and am on 5 1/2 days of a water fast. I was intermittent fasting before this and I’ve fasted for a couple days in a row in the past, but never beyond 2-3 days. I did ok for the 1st 3 days but day 4-5 I was pretty sluggish, tired, and my heart feels like it’s going to beat out of my chest. I couldn’t sleep last night due to muscle aches (felt like the flu), acid reflux, and I got sick. I was able to sleep for a couple hours this morning and feel a bit better – but wondering if I should quit and try again another time when I’ve had more ample time to prepare?

      Hi Phil,
      Sounds like you’re experiencing the first wave of deeper detox caused by your fasting metabolism. This does take a few days to activate and is the reason that you’ve not felt these symptoms during your shorter fasts. I honestly can’t advise you what to do now without having worked together – I’d need to be familiar with your background plus the reasons that you’re fasting. You could almost certainly push through and keep going, but I can’t say whether this would be the most effective (or comfortable!) solution.

  7. Hi Tallis, I attempted a water fast and made it to the morning of DAY 3. Early in that morning I felt like I had a slow heart beat and felt very tired. Is this normal? I’m wanting to start a water fast in 2 days, however, I’m nervous I’ll end up stopping it again. My goal is 7 days minimum and 21 days the most of my mind and body can! A little ambitious from just a full 2 day fast.

      Tallis Barker Ph.D.

      Hi M lee,
      Thanks for writing. Feeling tired is very normal for the first days into a water fast – and even longer if you don’t have any fasting experience. There’s a lot of detox to do! I can’t comment on your heartbeat without knowing more of the specifics of what had happened before then. The main thing is not to dive into anything too deep. Jumping straight up to 7-21 days is a big leap – which isn’t to say you can’t or shouldn’t do it. But do respect your body and mind along the way. Don’t force things, and if it doesn’t feel right, then stop. You can always pick things up with another fast, until things feel easier and more natural!
      All the best,
      Tallis

  8. What you write really makes sense now, especially since the 7-day fast rash is around four of the lymph nodes. The body is wonderfully made! One could speculate that a person who has so much toxins expelled as to develop a bad rash really benefited from the fasting “housecleaning”. 14 days would have been even better but this was my first time and it was not easy. What would be a sensible amount of time to wait until fasting again?

    1. Tallis Barker Ph.D. Avatar
      Tallis Barker Ph.D.

      Seven days is a really strong accomplishment for your first time – so I hope you feel good about that!
      In terms of the length of time before your next fast, think about it like this: if the human body is capable of doing a 40-day fast, then there’s no physical reason to wait at all after a 7-day fast. The issue is more psychological/emotional, and it’s extremely important to give yourself enough time so that you don’t go into the next fast meeting a lot of resistance from that part of you which felt deprived during the fast.
      We use food to distract us from boredom, to fill in the holes where we’re not feeling comforted or loved. It takes time and experience in fasting to clearly recognise this, and learn to free yourself from this. Until then, enjoy food in between your fasts so that when you fast, you can enjoy this too!

  9. Fantastic site and information! I like it better than Dr Fung’s book which is very mainstream and geared to shorter fasts. I bought two of your ebooks and finished them in the same day. Great information. I felt hungry and tired the whole time, I honestly expected a smoother ride.

    I was planning a 10 day fast but today on my Day 7 of waterfasting I broke it because I have just developed what I believe are called “Keto Rashes” on both arms and legs. Not much itching but it is very red. I have never had anything like it. Tallis, is fasting-induced rashes something you have come across?

    1. Tallis Barker Ph.D. Avatar
      Tallis Barker Ph.D.

      Hi Peter,

      Thanks for sharing. Jason Fung has done a lot of really great things for intermittent fasting, but, yes, when it comes to longer fasts I have to say that our approaches definitely differ…

      To answer your question: yes, I’ve come upon rashes quite frequently. The timing of your rash is very typical, and it’s something which can happen during or especially after a water fast. It can range from just a slight reddening of the skin to ‘prickly-heat’ looking red dots, and can be itchy or not. It usually lasts anything from a couple of days to a little over a week. It’s nothing to worry about, and, in my experience, is caused as a result of toxins passing through the skin, thereby irritating it. This also correlates with the greatest degree of ‘housecleaning’ during the first 7-10 days of a water fast.

      Based on what you described, the best thing you could have done was probably to continue your fast until the rash disappeared by itself. (To say anything more meaningful here, we’d have had to be working together through your fast.)

      The term ‘keto rash’ is a little confusing. If you Google the term, you’ll usually find something like: ‘researchers are still not entirely sure what causes a keto rash.’ In Western medicine, doctors all too often apply blanket labels to conditions about which they don’t fully understand, and which may or may not have different causes. (This holds especially true with autoimmune conditions, such as ‘Lupus’ and ‘ME’, to name just a couple.) In this particular case, doctors also have to admit that they don’t even know if ketosis causes a keto rash!

      Hope this helps,
      Tallis

  10. I am using a breath ketone meter. When should I worry if my levels are too high? At first during my 14 d of a ketogenic diet, it ranged from 1.7 to 2.6. Now since I am doing water fasting, the levels have slowly risen to 4.4, 7.2, and 6.7. I would like to know when I should worry and at what level should I end my fast.
    Thanks

      Hi Lydia,
      Thanks for sharing your concern. Fortunately, for most people (unless you’re diabetic) there’s hardly ever any need for concern! During a water fast, your body should give you whatever rate of ketosis is right for you! This is going to be considerably higher than anything you’d experience on a keto diet, so don’t let any arbitrary ‘good’ or ‘bad’ numbers put you off. If anything, the higher the ketosis, the better in this context – so it sounds like you’re doing great!

        Thank you so much for your quick response. My numbers are staying high and the weight is coming off. While I’m fasting I am also reading about nutrition and have decided to become a Nutritarian. In this way I can begin to give my body what it needs to repair itself after the fast. I will also continue intermittent fasting as well as incorporating 2-3 day fasts monthly. Thanks so much for all your advice. I learned a lot from your fasting articles.

  11. I’d it safe to do a seven day water fast once a month ??

    1. Tallis Barker Ph.D. Avatar
      Tallis Barker Ph.D.

      Hi Shawn,
      I’d say the question is why would you want to do a 7-day fast once a month?…
      And: are a series of 7-day fasts the most effective way to reach your goal?
      Context here is important.
      If you’re fasting to heal an illness, then the answer is definitely, yes, it’s almost certainly perfectly safe (assuming you eat an otherwise healthy diet). But in this case it often makes sense to try for a longer initial fast before backing this up with subsequent 7-day fasts.

  12. Hi, thank you so much for all the information. I am wondering if herbal teas (caffeine free) are ok during water fasts? Thank you

    1. Tallis Barker Ph.D. Avatar
      Tallis Barker Ph.D.

      Hi Lidia,
      Caffeine-free herbal teas are absolutely fine during a water fast in the sense that they won’t upset ketosis or cleansing. In fact, certain types of herbs can be used for their medicinal effect in promoting the cleansing of certain organs and body systems. The main reason to avoid herbal teas would be if you are more concerned with exploring the spiritual or psychological aspects of water fasting.
