    I was always told CFS was an autoimmune disease, I notice you say it is hormonal. That is very interesting. Have you found the symptoms of CFS to fully go away (at least sometimes) from a 40 day fast? Or how long of a fast does one usually need to recover? Let’s say the individual had severe fatigue (couldn’t do any duties, but not bed ridden, for twenty years. Did you experience any individuals like this, that after a forty day water fast, was able to go back to normal living?) I would love anecdotal stories if you have any, or your own personal experience. i.e., How many people have you treated with CFS (around) and how many found their symptoms go away, and how long a fast did they undergo? Also, what was their fasting experience like? Ex: Did they usually feel pretty tired all the time, as that is normal with CFS, but even more tired because of the fasting? What sort of signs would show up with such individuals that would indicate they should stop the fast? What were the normal detox / healing signs?

    Also, if one has not been able to do any activity for 20 years, the heart really starts to have problems from this. But it often doesn’t show up from western medicine. It just gets weak. It can feel like it is working overtime, heavy, hurting, etc. Now when one undertakes the 40 day fast, would healing mean the heart experiences this even more so, but not in an alarming way, and would this mean it is healing, and would that again be a good sign? What sort of signs would indicate you should stop the fast?

    Do you have a book you wrote that covers your research, etc? I would love to purchase it if you do! Dr Goldhammer recently published a book, I am so glad he did! But he said very little about CFS. Thank you so much for all your work!

    1. Hi,
      Thanks for writing. There are a lot of questions in here, so I’ll focus just on the main one. CFS can be an autoimmune disease, but – as with so many other so-called ‘immune diseases’ – most people never get tested for antibodies, which is the only way to know whether an illness truly does have an autoimmune component. The fact of the matter is that, most people with symptoms of CFS aren’t going to have antibodies anyway, because, more fundamentally, CFS is a hormonal issue in which the adrenals (and often the thyroid as well) become dysregulated. The same often applies to people who say they have Hashimoto’s, and especially so when they’ve been working with an MD who doesn’t fully understand autoimmune issues. In other words, not everyone with hypothyroid symptoms actually has antibodies – so here too, the issue consists more fundamentally of a hormonal dysregulation (hypothyroidism) before any autoimmune disease comes into play (true Hashimoto’s).

      I’ve worked with dozens (if not hundreds) of clients suffering from CFS, and extended fasting tends to elicit a lot of healing. With the correct fasting protocol, I’ve seen numerous clients fully recover their energies, to go on and live a full life again.

      Hope this helps,
      Tallis

  2. I ran across your web site today and am excited to sign up for a 30-day water fast. I’m on a medication and it will impact me for another two months, so wait I must! I am curious about what weekly tests will be required, as I’m speculating potassium, magnesium phosphate and maybe sodium will be required. If you would send me the test list, I will check my local lab to make sure they are available as well as the cost. Thank you soooo much.

    1. Hi John,
      Thanks for writing, and I’m glad you’re feeling excited to move your health forward with a water fast. To answer your question, there’s no single test list which applies to all people at all times. The same applies to medication: depending on what it is, you’ll either need to wait it out or not, depending on how the given drug impacts on fasting metabolism. If you’re expecting to fast in a couple of months, I’d suggest signing up for a single (pre-fast) consultation in the near future, so we can cover these questions in depth for your specific case, as well as discuss preparations for the fast and confirm whether or not a 30-day fast is indeed the right thing for you.
      All the best, and hope to hear from you soon,
      Tallis
