WELCOME!

Hello. I’m Dr. Tallis Barker

In addition to the many articles and videos here on this website (see below), I also provide more private and personalised support as a water fasting coach.

I’ve successfully guided over 700 hundred people from across the world through fasts lasting 3 to 40 days.

Although I coach fasts undertaken for numerous reasons, I specialise in helping people heal from chronic illness such as:

  • Long Covid
  • Gut issues such as IBS, SIBO and ulcerative colitis
  • Autoimmune issues such as allergies, asthma, chronic fatigue (CFS) and rheumatoid arthritis (RA)
  • Hormonal issues such as insulin resistance, adrenal fatigue and hypothyroidism
  • Fibroids, ovarian cysts and even cancer
OVER 700 CLIENTS
Successfully coached through 3 to 40 day fasts

For people unfamiliar with water fasting, the idea of giving up food can be frightening. But the fact is that homo sapiens have been successfully fasting for millennia.

Many people today practice intermittent fasting as a basic lifestyle, but longer fasts are also possible in order to go much deeper into healing.

You can completely recalibrate your body from the ground up, allowing yourself to heal. The way to do this is through water fasting.


Water fasting is completely safe for the vast majority of people. With guidance from an expert, you too can make the most of your fast and begin your healing journey.

FASTING TRIVIA

We all know the most famous examples of religious 40-day fasts, but you probably haven’t heard others.


For example, the Greek mathematician Pythagoras demanded that all his students undertake a 40-day fast in order to sharpen their minds!

  • Physical and spiritual cleansing: from fear to love
    Does the thought of water fasting frighten you? It’s completely natural to feel fear before and even during your first few water fasts.  After all, unlike our ancestors, you’ve probably never gone without food for more than a few hours, let alone a few days.  […]
  • Facing your ego through water fasting
    As important as any physical cleansing, water fasting also challenges you with emotional and spiritual blocks, bringing you face to face with your ego and fears.  In a way, your journey through water fasting mirrors the entire spiritual path: both within each fast, as well […]
  • Deeper states of consciousness while fasting
