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. Hi Tallis.
    Thanks for this site.
    I have a concern. I’m on my 6th day of water fasting and I’m experiencing more and more acid reflux. It’s makes it hard to drink water since it seems it gets worse if I drink too much.
    Should I break the fast? I was aiming for 10-15 days but I’m not happy about the acid reflux that gets worse. I feel fine in the morning when I’ve slept and haven’t had a lot of water.
    Any insights on this issue?
    Thank you.
    Louise

    1. Hi Louise,
      Thanks for sharing. Acid reflux is nasty, and can certainly happen during the early days of a water fast. However, as your digestion switches off over the first few days, it should slowly subside.

      I think you’ve already hit the nail on the head. You say it gets worse if you drink too much. How much are you drinking? My guess is that by drinking too much water, you’re overstimulating your stomach (even if it doesn’t have to produce acid to digest any food). Especially if you’ve had acid problems in the past, your stomach is going to be overly sensitive to anything entering it, and this even can include pure-and-simple water.

      Many people believe they should be drinking at least 3-4 litres/quarts a day. Many Americans, in particular, believe they should be drinking even more than this. Unless you have a huge amount of toxins to flush, this simply isn’t the case. A much more reliable indicator of how much to drink is usually your thirst, and usually 1-1.5 litres/quarts per day is plenty. Of course, your ego can play tricks on you. If you miss eating, it can feel soothing to drink instead. But this is entirely different from what your body needs. Over the years I’ve been fasting, I’ve noticed that the amount I naturally want to drink has declined, both as a result of having no emotional need to put something in my mouth, as well as from having slowly physically reduced the amount of toxins over many, many fasts. Nowadays, if I’m not actually dry fasting, I find my body is happy with 0.5-1.0 litres/quarts per day, although this may temporarily increase by about a half litre/quart during periods of stronger detox.

      Let me know how you get on after you reduce your daily intake of water. For now, there’s no reason to think about stopping your fast.
      Until then, all the best,
      Tallis

      1. Thank you so much for your reply.
        I did start drinking less water today and have had no signs of acid reflux so you are absolutely right! I was drinking way to much water.
        Since this is my first fast ever -I’m 41 and have had a lot of antibiotics over the years – I do experience a lot of”stuff” coming out. My tounge is milky white, brushing it helps very little. My 3rd day was like a day in hell. Ha ha ha. And I do also have the feeling of wanting to fill myself with water.
        Now I know I don’t have to worry about my water intake. I really appreciate you’re insights. It’s very helpful. I’ll truck on 🙂
        Namaste

        1. Yes, Louise, keep truckin’ on 🙂
          Glad you survived Day 3! Given that this is your first water fast and given your past with prescription drugs, it may well continue to be a relatively rocky road for a while, possibly both for the rest of this fast as well as for the next few fasts. But it sounds like you have a lot of resolve to keep going, so good for you! I can promise you that if you continue to water fast in the future, it’s going to get easier, smoother and ultimately even enjoyable!

        2. Here are some lessons I’ve compiled on fasting.

          From the Bible. = “I fast twice in the week,”
          Luke 18:12
          Pharisees Fasted two consecutive 24 hour days on Monday & Thursday

          It sounds simple in theory, of course: Refrain from eating anything (or drinking any beverages other than water) for 24 hours. Your body has plenty of calories stored to carry you through those 24 hours, and the pause from digestion will give your body a chance to focus its healing energies on other parts of your body. The majority of the immune system is in the gut.

          Why fasting?
          Fasting has been used from Biblical times through the modern world to help purify and heal the body. It can help detox your liver, kidneys and digestive tract. It also encourages you to rethink your eating habits.

          Give your digestive system a break and encouraged more rapid healing throughout your body. You may notice some detox effects (like bad breath) or a difference in your energy levels. This is all a normal part of the fasting process, and it indicates your fasting is working!

          Fasting is not an escape from the problem, but an attempt to enlist the help of your God created body in solving the problem.

          Breakthrough.

          “I proclaimed a fast there beside the Ahava Canal, a fast to humble ourselves before our God and pray for wise guidance for our journey—all our people and possessions. I was embarrassed to ask the king for a cavalry bodyguard to protect us from bandits on the road. We had just told the king, “Our God lovingly looks after all those who seek him, but turns away in disgust from those who leave him.” So we fasted and prayed about these concerns. And he listened.”

          The people of Nineveh listened, and trusted God. They proclaimed a citywide fast and dressed in burlap to show their repentance. Everyone did it—rich and poor, famous and obscure, leaders and followers. When the message reached the king of Nineveh, he got up off his throne, threw down his royal robes, dressed in burlap, and sat down in the dirt. Then he issued a public proclamation throughout Nineveh, authorized by him and his leaders: “Not one drop of water, not one bite of food for man, woman, or animal, including your herds and flocks! Dress them all, both people and animals, in burlap, and send up a cry for help to God. Everyone must turn around, turn back from an evil life and the violent ways that stain their hands. Who knows? Maybe God will turn around and change his mind about us, quit being angry with us and let us live!”

          A lesson in the American culture name scheme called breakfast lunch dinner.

          The word ‘Dinner’ used to refer to breakfast. The word “dinner” comes from the Old French word “disnar”, which in fact means “breakfast”.

          So how did this word that meant breakfast end up being pushed back in the day to describe the meal latest in the day?

          Traditionally dinner (meaning ‘breakfast’) was the first meal of the day, eaten around noon. It also happened to be the biggest meal of the day at around 12pm, with a lighter meal coming later known as supper. Eventually, more meals started being added to the day with people eating meals before the large noon meal of dinner. Rather than calling these earlier meals that broke the fast by the word that means breakfast (dinner), the name “dinner” now stuck as meaning the largest meal of the day.

          As time has passed, in most cultures that use these words to describe their meals, the largest meal of the day gradually got moved later and later in the day until its meal time was around the time we used to have supper (which used to be a light meal). So gradually this meal that bears the name (translated) “breakfast” is now the meal we eat before we start the fast and the literal translation of “dinner” is now the word we used to describe our early morning meal of breakfast. In most cultures where this shift has happened, “supper” is now considered to be the proper name for a midnight snack.

          It should be noted that there are still many cultures that use these words to describe their meals that don’t go by the “Breakfast, Lunch, Dinner” name scheme; rather, they now go with “Breakfast, Dinner, Supper”, choosing to refer to lunch as “Dinner”. In which case the meal bearing the name “Dinner” didn’t move at all. Just one extra meal got added earlier in the day.

          1. Abel – thank you for an absolute awesome teaching that I will save immediately and ponder upon daily!

            1. Thank you and I pray you reach all your health goals. 😊

  2. Hi Tallis,

    Thank you for such a great post and for your informative replies to everyone’s comments!
    I’m currently on a calorie-restricted diet (around 400 net, but eating 1000 due to a 600 calorie burn through cardio). What would you advise re: working out while on a long fast like this? I generally go for a walk in the evenings too and burn another 250 calories, and which is much less intense than my daily HIIT workouts at the gym. Would you suggest light cardio like a walk? I worry that any more would exhaust me.

    Thank you!

    1. Hi,
      Thanks for writing. I’ve responded in greater detail to exactly this question in comments elsewhere on the site. The short answer is: so long as you don’t reach the point of feeling out of breath or that your heart is racing, walking is fine. In fact it’s extremely healthy. Just make sure you don’t push yourself beyond your limits. While fasting*, you’re going to get out of breath much sooner than usual, so don’t force yourself to walk at a pace which you ‘think’ you should be able to manage. Follow your heartbeat and breath, and make it comfortable and sustainable. Otherwise you run the risk of needlessly burning up a lot of extra muscle.

      *In your email, you use the word ‘fasting’ after also mentioning a calorie-restricted ‘diet’. I’m assuming here that by fasting, you really do mean fasting: that you now on zero calories and in ketosis.

      Hope this helps,
      Tallis

  3. Please just let us know if you stop the fast for a day would you go trough the same hard first 3 days again. Im feeling great and im so sad i might have to break my first long fast

    1. Keep water fasting. When you do eat and fill yourself with calories. And when you are filling yourself with calories stay away from chicken and beef. Learn to not eat chicken and beef anymore. Stick to every vegetable and every green and every fruit. Zero fast food and carbonated drinks. You can water fast two 24 hour days per week. Fasting 2 days per week is an old practice. The more you get used to it the easier it becomes. Remember to shut the gut off so that your immune system will have the energy to heal what needs to be healed.

    2. Sorry not to have written before now – I’m afraid over the last few days I’ve had to put business before the charity work on this website. Also, though, part of me wanted to avoid answering your question, because I don’t believe this is the right question to be asking. Apropos, I hope you were able to read my post “Telling friends and family about your fast (or not)” before you went to the birthday party and faced that sliced of cake…

      Otherwise, there’s no clear answer to your question anyway, about whether breaking the fast for a day would cause the same roughness when you continued fasting afterwards. It all depends on how much you eat over what period of time, as well as how easily you jump into ketosis. Most likely, it wouldn’t be as rough, but exactly how much less depends on the factors I mentioned above.

      Hope you found the answer yourself which was truest to you,
      Tallis

  4. So im going though the biggest dillema. Im on my 6th day fast and i was planning on doing it for 20 days.
    I have been doing great even though the first 3 days were quite hard.
    Its my friends birthday on sunday, and they expect me to have dinner and a couple drinks. My friend wasn’t planning on celebrating it this weekend but she changed her mind. I cant tell anyone im fasting because they are just gonna call me crazy. What do i do? I was honestly thinking about missing it just because I finally feel great doing a fast. But i cant do this to her. Im wondering if i have a small dinner and a couple drinks on sunday and i start again my fast on monday, will i have to go trough those hard first 3 days again? Like, does everything start from 0? Will i have all the lethargy and brain fog again for 3 days? Those were the longest days of my life. Im finally feeling great, no cravings, mental clarity and heaps of energy. Im so upset that i might have to start everything again. 🙁

    1. Thanks for sharing, Ruby.
      If only there were a simple magical solution to your dilemma…
      Whether or not to tell friends and family about fasting has come up a few times recently on waterfasting.org, and I think it deserves some extra attention, precisely because it does affect so many people.
      I’m going to start posting weekly on the website, and this will be the subject of the first post on Saturday – if you don’t mind waiting until then 😊. You’ll be able to find it listed at the bottom of each page.
      Until then, glad to hear all is going well, and please don’t let thoughts of what to do on Sunday spoil your time in the here and now.

  5. Hello

    Should I be concerned about eating “junk” right before a long water fast? As in, will it rot inside of me for the entire duration? How could one prepare and how long? Would 2-3 days of clean eating and senna/laxative tea be an okay start? I’m really obsessed and worried about feeling discouraged or having food I’m allergic to inside of me, trapped. Apologies if I sound silly!

    Thank you

    1. Hi Em,
      Good question. You don’t sound silly at all 🙂
      The answer is yes, you should be concerned!!!
      It’s not like it’s going to kill you if you eat badly beforehand, and it’s unlikely you’ll end up with an allergic reaction, but you’ll definitely feel better if you eat well beforehand.

      This is an important topic, and come to think of it, I’ve not yet written about it on waterfasting.org, so I’ll post on it in the coming weeks.
      Suffice it to say that the preparation time in your diet before the fast largely depends on what/how you eat now. As a vegan who eats plenty of raw, I can pretty much jump into any fast with absolutely no dietary preparation, but I also recognise that other most people eat differently. Just think about it, though: the ease into which you can jump into a fast says something pretty fundamental about the health of the diet you’re eating…

      Very briefly for now, I’d emphasize giving yourself about 3 days of eating light, and totally avoiding meat as well as cutting back on dairy and grains as much as possible. I’ll post a much more detailed version soon.

      Hope this helps for now,
      Tallis

  6. I had some chicken broth yesterday to be able to get trough my day. It worked great.
    Im on day 4 now and i feel great. Im finally able to understand what is the mental clarity people talk about while on fast. Its real. My mind feels so clear today its hard to explain. I have been so productive.
    Physically im still not great, but hopefully it will improve. My cravings have subsided.
    Just would like to let people know to stick with it! It will all pass! I was having the worst day yesterday but today im a new person.
    I had been having kidney problems anf i heard that fasting can put even more pressure on the kidney because off all the toxins its passing. Is there any chance that my kidneys could get even weaker because im doing a fast?

    1. Glad you’re feeling great.
      Make no mistake about the chicken broth though. Either:
      1) The less likely option: It made you feel great because it loaded you with so many calories that it restarted your carbohydrate-based metabolism – in which case this ISN’T a water fast!
      2) The more likely option: There were no significant calories in there, which meant that there’s no physical reason it made you feel better!!! Simply, you it gave you an emotional crutch – a kind of non-calorific “comfort food”, which effected your physical perception of the fast. Also, you were probably already moving out of the toughest phase of your fast anyway
      In other words, in scientific terms, the chicken broth didn’t help you in the slightest!
      If you need “comfort” from something warm during a fast, I’d recommend hot herbal teas instead. Any nutritional content from the broth – be it calories, vitamins and minerals or anything else – is only going to interfere with the biology of your fast.

  7. 78 hours fast so far 🙂 its been my longest fast .. i found that keeping my mind busy really helps going through the first days .. just wish my body wasnt so tired ..
    just measured my blood ketones and they are on 3,9mmol/l .. its exciting seen those numbers going up .. do you know what is the maximum of blood ketones we could have in our blood? Is there any dangerous number that it could get to?

    is it true that scars on the skin desapear on prolonged fasts? What about stretching marks?

    Thank you so much ! I feel like talking to you is giving me energy to keep going 🙂 hope one day i could have as much knowledge as you and hope i can be as positive as you are ! 🙂

    1. Yes, it’s encouraging to see those ketone numbers going up. The higher the better, as it shows that you’re efficiently converting fat to energy!

      Yes, working with a fasting guide to coach you through your experience DOES give you energy and generally makes the whole process smoother. That’s why I offer personal consultations on this website, so that clients and I can stay in closer, sometimes almost round-the-clock contact!

  8. Hi tallis, i havent been able to get a good sleep since i started the fast. Its 3:30am here now and i woke up after a 3 hours sleep. I dont know what could help my sleep as i already have no energy all day.
    My last blood ketones results were 2.3mmol/l .. did i stop burning muscle and am i burning fat now?
    Thank you

    1. Fasts longer than a day or two definitely change sleep patterns, and often you end up simply needing less sleep – completely independently from the energy you have (or don’t have) during the day.
      If you started your fast on Sunday, you’re certainly burning primarily ketones at this point 🙂

      1. Tallis, if I’m taking antidepressants, do i need to stop while fasting for a true fast? Can i keep taking them

        1. Hi Rae,
          Thanks for your question. Well, it all boils down to what you mean by ‘true fast’…

          On a physical level, your meds aren’t going to interfere with ketosis and the ability to burn fat. So if the goals of your fast are purely physical, then, sure, keep taking them.

          To me, though, a ‘true fast’ goes a little deeper. Ultimately, you can’t totally disconnect from one another the physical, emotional and spiritual aspects of not eating. Fasting IS going to affect you emotionally, as it does everyone, and a part of fasting involves your emotional relationship with yourself when you take away food. Of course, the fact that you’re on antidepressants means that you already have issues to deal with on an emotional level. Continuing to take the antidepressants will certainly affect your experience emotionally of the fast, and in this sense the meds clearly interfere with the fast.

          Don’t get me wrong. I’M NOT telling you to stop taking the antidepressants during your fast. Rather, I’m saying that it all depends on 1. your goals of the fast, 2. the severity of your depression, 3. the length of the fast you’re planning. The solution doesn’t have to be black and white, either by taking your meds or not taking them. Changing the dosage during the fast is another possibility, but it all depends on the particulars of your case, and that’s something which is definitely best resolved by talking to your doctor.

        2. I say stop 🛑. How do Tallis feel?

          1. There’s never a simple blanket answer when medications are involved. Every case is different. In an ideal situation, of course “stop” is the way to go. But real life, alas, is often much more complicated if you want to aim for long-term success. In my view, it would be totally irresponsible to say “stop” without knowing the full circumstances here – especially in the context of an internet forum in which we don’t even have personal contact! It’s always better to be safe than sorry, both when starting your journey into fasting as well as starting to come off prescription meds into a more natural lifestyle.

            1. Wait. I mean to stop meds …. did u understand my idea?

            2. Ok I understand thanks Tallis for your quick reply to us all. 👍🏼

  9. Hi faith, im glad to see that we are together in this. How were your first 3 days? I also dont tell any of my friends or co workers that im fasting .. so im always using the excuse of ‘i dont want to eat it because im not feeling too well’ or ‘no thanks i already had so much food’ .. its hard telling people about a fast as they would always try pushing you food .. but feeling sad about what happened wont help you .. it already happened .. so just stick to it and push trough! 🙂 let me know how everything goes

  10. Hi tallis 🙂
    Thank you for your answer!
    I have heard that some scars desapear on a prolonged fast. What about stretch marks?

    My last meal was at 11pm on sunday night. And now is 8:30pm on wednesday here in australia.
    Those are my blood ketones readings:
    7 pm monday 0.6 mmol/l
    5pm tue 1.3 mmol/l
    9am wed 2.3 mmol/l
    Am i officially burning fat?

    Im still getting the weaves of exhaustion. They arent as strong as before though. I hope it wont last long.
    I cant wait for the part where we arent so lethargic

    1. Dear Isabela

      I also had my last meal Sunday evening at 10:00 and it is now 12 past 1 the afternoon in South Africa. I am trying to do a 7 day fast, but this morning a friend offered me a very small peach (the size of a very small plum) and I did not want to tell her I am fasting and just declined but she insisted so I ate the peach but hated every second of it – because I was already in day 3 and could never get it right so far. Pls tell me you guys that this small piece of fruit will not hinder ketosis?? But I just wanted to say you go girl and I am with you in this and I am also trying my utmost best.

      1. So nice of you to support each other like this :-).
        Don’t worry about the peach. It’s definitely not the best, but it’s not the end of the world either. There aren’t enough calories to significantly alter your ketosis. The worst that can happen is that it reawakens your digestive juices to some degree and so causes hunger.

  11. I felt fine on day one and two of my water fast. But on third day im dealing with real cravings and lethargy. To the point that im nearly giving up. I thought the first and second day supposed to be the hardest ones. Why am I struggling so much on the 3rd one? Is it gonna subside? I dont think i could cope with another day like this

    1. Hi Matt,
      The third day IS often the hardest day for some people.
      The lethargy is probably due to ketosis not having completely developed yet, but that fact that you say you have cravings also suggests that your ego is resisting the fast (which of course is completely natural and something to be expected in your first few fasts). That emotional resistance can certainly sap you of physical energy too.
      Both will subside. It’s just a question of whether you have the patience for yourself.

      I’m guessing that you’re fasting on your own, alone. I would expect that in a more supportive environment, such as on a retreat, your symptoms would be much less bothersome, if noticeable in the first place. Emotional support ALWAYS leads to minimising physical symptoms while fasting.
      All the best,
      Tallis

  12. I know this might be a weird question, but im getting laser tattoo removal. Im wondering if a fast will help it fade away quicker. Im obviously doing a fast for other health reasons as well.

    1. Fasting does accelerate healing, but I doubt it would make too much difference here, and especially when your body has other issues to deal with. Still, it won’t hurt either 🙂
