  1. Hi! The last time I did a seven day fast, I lost a lot of hair (it was coming out by the handful). It took over a year for it to grow back. I’m wondering what you suggest so that this doesn’t happen in the future?

    1. Hi Anonymous,
      Thanks for writing. There can be multiple reasons for hair loss through fasting. Some come from the positive impact on stem cell regeneration, but hair loss can also occur as a negative symptom driven by hormonal or nutritional deficiency. Given that in your case a 7-day fast caused hair loss (it happens more frequently after 21-40 day fasts), I’d definitely want to exclude the negative possibilities before you think about fasting again. However, to get to the bottom of this issue would require a much longer conversation – the kind we’d have on a full consultation.
      All the best,
      Tallis

  2. Good day my son has just finished a 14 day water fast he now seems very anxious slow moving and lacks drive he doesn’t even wants to take a shower, also he seems to have a slow reaction to questions. Should i be concerned???

    1. Hi Antom,
      Thanks for writing. I’m afraid it’s very difficult for me to say anything without having worked together with your son through his fast, and without knowing his full health background. In general, energy should start picking up soon after breaking the fast. If this doesn’t happen, it usually indicates a problem with either (1) the refeeding protocol, (2) breaking the fast at the wrong time, or (3) health issues prior to the fast which have not fully resolved through the fast and which are now becoming aggravated by returning to a regular diet.

      Besides this, I’d need to have a full discussion with your son in order to understand what’s going on. The bottom line is that fasting can and should be a powerful force for positive change. But equally, it can and often does get complicated when someone – especially someone with health issues – is fasting without adequate knowledge.
      Hope this helps,

  3. hi
    not sure if you can help,but if so i,ll be happy to enroll
    male 67,on no medication,non smoker,non drinker for some years now
    but have nerve problems in feet/calves
    had every test going but nothing is showing as relevant
    recent bloods all normal apart from low tsh
    suffer and have done so with anxiety for many years and feel everything is amplified with anxiety
    question,,,,would fasting be helpful with this and the neuropathy
    thank you
    jon

    1. Hi Jon,
      Thanks for writing, and sorry about the slow response. I just got back from summer vacation. I’ve worked with many clients suffering from peripheral neuropathy issues, and fasting tends to offer a lot of relief for many people. I recently had a client similar in age and lifestyle to yourself (no meds, no smoking/drinking) who healed from similar symptoms on a 21-day fast. I know thqt probably sounds like a long time, but he even did it with no prior fasting experience. I wouldn’t want to suggest that you need exactly the same protocol – we’d need to look into your case history in a lot more detail first – but I do want to motivate you towards fasting, and experiencing the powerful healing which extended fasting can offer.

  4. Hi Dr. Barker,

    On Tuesday night I came down with the flu. It’s not a stomach flu but I lost my appetite. I thought it would be a good chance to try a water fast. So all I’ve had since Wednesday at noon is water, unsweetened electrolytes, and some mineral drops, some homeopathic medicine (ColdCalm)

    It’s now early Saturday morning and I realized that I haven’t taken my antidepressants or BP medication since Wednesday.

    I suffer from high blood pressure which has gotten pretty unpredictable over the past few months. I’ve had increasing issues with random dizziness which does not seem to be related to a drop in blood pressure. I have issues with digestion where I seem to get bloated no matter what I eat. And, while my body tends to run hot, recently I have felt an overheated sensation which doesn’t go away! (Separate from the low fever I had/have with the flu.)

    I’m wondering if you could comment on how many errors in judgement I’ve made, but I do feel that I’m listening to my body.

    Thanks,

    Arif

      Hi Arif,
      Thanks for writing, and apologies for the delay in responding. Fasting with meds is always potentially tricky, and should ideally involve guidance both from your doctor as well as from a water fasting expert like myself. The fasting symptoms you describe (such as dizziness) can involve multiple causes, and blood pressure may or may not be involved.
      Listening to your body is extremely important both in fasting and in life! The difficulty is that most of us have already lost a lot of that connection and either can’t feel or misinterpret what the body is actually saying.
      Hope you’ve recovered from the flu by now!
      All the best,
      Tallis

      1. Thanks for your reply Dr. Barker,

        tldr: My unplanned 4-day water-fast had dramatic effects on my weight management and eating habits. Cold-turkey withdrawal from an anti-depressant is continuing.

        Before I go into the results of my actions from last week, I wanted to clarify that there are only two types of dizziness that I was referring to above. Neither are related to fasting.

        One is something I had been experiencing with increasing frequency over the past 2 years. At first it seemed to be related to a drop in blood pressure, but with a BP cuff I learned that my blood pressure always went up during those episodes. It could be some kind of vertigo too – not sure. I have been pursuing medical assistance with that but there are no answers yet. I haven’t experienced this again since completing the fast.

        I attribute the other dizziness I mentioned to the deliriousness that accompanies a fever during the period I was unwell last week. But it could also be contributed to by the antidepressant withdrawal.

        Moving on to the fast: I fasted for four days. It was an unplanned fast that I decided to take on when I realized I didn’t have much appetite, which I attributed to the flu. I had never specifically intended to go into ketosis but clearly that happened.

        I added unsweetened electrolytes and baking soda to the regimen. I started the electrolytes on day one. The choice to use baking soda came on day three when I suspected that the kidney pains I was experiencing were due to acid in my urine from high ketone levels. That seems to be helping

        By day four, my face had lost a lot of the doughboy appearance I’ve developed over the last few years. After breaking my fast, I noticed a dramatic difference in what it means to be hungry and what it means to eat. What I mean is, I was fortunate not to have hunger pangs at any time during the fast. And now, I still haven’t been eating in response to hunger. Ok, there is a certain craving to put something in my mouth sometimes. But it’s not connected directly to sensations in my body. So I’m cautiously trying to avoiding eating except when I think I’m actually hungry. My caloric intake is still rather low, but there is no deprivation going on. I have a lot of extra weight to lose (if I want to) so there isn’t really a pressing need to eat calories. So far I’ve been consuming salad, protein/fat (tuna, chicken, salami, cheese, olive oil), some broths, carefully selected health bars that don’t have preservatives (I bought IQ Bars and Aloha bars in the stores last week). I did eat a small amount rice the last couple of days. I continue to drink lots of water as I fight off the residual congestion and dry sinuses from the flu (or from the keto flu, or whatever).

        I am having trouble sleeping: I attribute this mostly to the withdrawal from antidepressants and to having a residual cough from last week. I don’t realy have any evidence that the “withdrawal” is responsible for poor sleep.

        I am currently taking no medications (even ones I’ve been prescribed). Let’s see how that works out!

  5. I am finishing a 10 day water fast tomorrow and considering going right into a 30 day diet of intermittent fasting 20 with a 4 hour eating window. Does this work or should I take some time to adjust after reintroducing food?

    Also,I have been considering doing a keto/paleo/carnivore diet (not sure how strict yet) to stay in ketosis.

      Hi David,
      Thanks for writing. Congratulations on finishing your 10-day water fast. When I’m working with clients, I put a big emphasis on ‘listening to your body’ – and especially during refeeding. Having a ‘plan’ for what to do after a fast is a mental construct which may or may not have anything to do with what your body actually wants. Truly listening to your body isn’t easy, though, when there are habits, plans and other distractions of life clouding your mind. In short, you could try IF, but it’s not for me to say whether it’s what your body actually wants.

      In terms of wanting to stay in ketosis after the fast: that also sounds like a mental construct… One thing I’ll say is that there’s no need to stay in dietary ketosis when you’ve already become much more deeply fat-adapted through your fast.

      Hope this helps,
      Tallis

  6. How can water fasting make a bladder infection worse at first ? Why does that happen I just want to understand it so I know what I’m getting myself into

    1. Dr. Tallis Barker, D.Phil., Nat.Dip. Avatar
      Dr. Tallis Barker, D.Phil., Nat.Dip.

      This is a very complicated question which I can’t answer fully here, as the situation really varies from person to person – and I don’t want readers to draw general conclusions from individual cases. To summarise, though, the symptoms of a bladder / UTI infection can worsen due to the fast eliciting additional acidity and general toxicity passing through the urine or as a quasi Herxheimer reaction. It’s extremely important to be able to know how far to allow symptoms to develop. In an ideal world you push through and allow the healing process to lead to a recover, but this isn’t always possible – in which case pushing too hard can lead to a deterioration of the underlying situation.

      1. That makes perfect sense thankyou! That’s why when I did a 6 day water fast it wasn’t getting better and felt kinda worse bc all of those acids being released since I know I have lots and lots of toxins stored within me
        So is water fasting a good idea for me at all right now ? I really don’t know how else to get rid of this infection though

          Dr. Tallis Barker, D.Phil., Nat.Dip.

          Hi again,
          Like I said in the last reply: this is a complicated question which I can’t answer fully here, as the situation really varies from person to person. This is exactly where a full consultation should come into play – in order to look at the full range of factors driving your specific case. Only after taking the full picture into consideration would it be responsible for me to say whether water fasting might be a good idea for you right now.
          Hope this helps,

  7. I’ve had a chronic bladder infection that doesn’t go away nothing has worked only managed.. could fasting rid it for good ?

      Dr. Tallis Barker, D.Phil., Nat.Dip.

      Hi Nicole,
      Thanks for writing. Fasting can certainly help to resolve chronic bladder infections. However, as is true for any form of UTI, things can also get tricky when fasting, with symptoms often worsening before they get better. When I’m working with a client, it’s important to be able to distinguish when you should push through and when you should stop, and this is something which is hard for someone to assess alone.
      Hope this helps,
      Tallis

  8. I’ve heard mixed reviews on the impact of fasting on bone health. As an experienced faster and also one recently diagnosed with osteoporosis, now I’m concerned about attempting an extended fast. I would think that fasting would improve bone density? Your comments would be most helpful going forward.

      Dr. Tallis Barker, D.Phil., Nat.Dip.

      Hi DEB,
      Thanks for writing. You’re right about the pros and cons of fasting on bone health. Although the final results of an extended fast are likely to lead to higher bone density (due to stimulating osteoblasts), the fast itself is likely to draw on it. This is because the body uses bone tissue to balance acids in the blood (using the phosphate ion of the calcium phosphate which comprises bone tissue). One underlying reason for osteoporosis is chronic tissue acidity, which forces the body to constantly draw on bone tissue – and during the fast itself this process becomes intensified. However, fasting is likely to lead to a long-term reduction of tissue acidity after the fast, allowing the body to subsequently accumulate more bone tissue in the future – also combined with the beneficial effects of fasting on osteoblasts: the cell which lays down bone in the first place. It would be a question of understanding the specifics of your case in order to determine the best approach to fasting: to find the safest and most effective middle road to future bone health.

      All the best,
      Tallis

      1. Thank you so much for this clarification! I can now do the research necessary before I proceed. I sincerely appreciate your knowledge and insight. And your willingness to share.

        1. I’ve recently completed a 3 day fast, trying to rekindle my fasting practice. I was derailed by covid 3 + years ago and now some long covid issues. Along with other general health issues, and knowing that a truly long fast will not be supported in my circumstances, I am wondering if a series of shorter fasts of,say, 7-14 days will eventually arrive at the level of healing experienced during the prolonged fasts of 20+ days.

          1. Dr. Tallis Barker, D.Phil., Nat.Dip. Avatar
            Dr. Tallis Barker, D.Phil., Nat.Dip.

            Hi Deb,
            Without having the in-depth knowledge acquired through a full consultation, it’s very hard to say anything definitive. For someone who is totally healthy, I’d say that two 14-day fasts are broadly ‘equivalent’ to a single 21-day fast. But when there are complex, chronic health issues involved, it’s also going to be influenced by the specific symptoms involved. Some symptoms really do need a longer fast in order to heal. Perhaps most importantly, though, some people with chronic health issues such as Long Covid can actually do damage to themselves by fasting for too long, pushing their already burdened immune systems beyond the limit. So, for someone like you, it’s going to be a complex situation which needs a lot of thought in getting it right!

    How do you regualte the amount of water intake is required during a water fast? What about eliminating mucoid plauque during your fasts, do you see these eliminations?

    1. Dr. Tallis Barker, D.Phil., Nat.Dip. Avatar
      Dr. Tallis Barker, D.Phil., Nat.Dip.

      Hi Christopher,

      Thanks for your questions. The whole point is NOT to ‘regulate’ water intake. It’s to get out of your head – and what it ‘thinks’ is right – and listen to your body. The problem is that most people have largely lost a good, solid connection with what their body wants – and this includes water intake. It’s my job to help clients tune into this, so they do know how much to drink! There’s no fixed amount. It’s largely individual, and it also fluctuates from day to day.

      Mucoid plaque can be eliminated on fasts, but it tends to take place beyond the first two weeks of fasting, if at all – because not everybody carries mucoid plaque.

      Hope this helps,
      Tallis
