Water Fast Coaching and Nutritional Therapy

Dr. Tallis Barker | Extended Water Fasting Specialist | Registered Nutritional Therapist | Associate Naturopath

PERSONALISED NUTRITIONAL THERAPY

From fasting to long-term nutrition

Dr Tallis Barker is best known for his work in extended water fasting. He is also a Registered Nutritional Therapist (NT.Dip.), offering personalised nutritional support both after fasting and as a standalone service.

Online nutritional therapy offers a more individual way to look at your diet, health history and longer-term nutritional needs — whether you want to build on a fasting experience or simply develop a more considered approach to everyday nutrition.

Basic Nutritional Support begins with a 75–90 minute initial consultation.

Available both after fasting and as a standalone service

For many clients, completing a water fast is not the end of their health journey – it is the beginning of a new relationship with food and diet.

Once your fast and refeeding period* are complete, the question becomes: how do you continue from here?

Many clients I have coached through fasting want to use the experience as a starting point for longer-term nutritional work. Rather than simply returning to their previous eating habits, they want to understand what dietary approach is most realistic, appropriate and sustainable for their individual needs.

The reality is that many people living with ongoing or complex health concerns also need more than just a single fast to heal, which means that a therapeutic diet in between fasts becomes crucial in keeping up the forward momentum.

I also work with people who aren’t yet ready to take the plunge into water fasting, or who want to improve their nutritional foundations before a future fast.

Fasting → Refeeding → Personalized nutrition → Long-term support

*The refeeding period itself is already covered by full coaching for any water fast.

My starting point is food itself. Rather than applying a fixed dietary system, I look at your current diet, health history, nutritional needs and how your body responds to different foods. The aim is to identify the changes that make most sense for you now, while recognising that those needs may continue to evolve over time.

Before your initial consultation, you’ll complete a detailed health questionnaire and diet diary.

Your first nutrition consultation lasts 75-90 minutes.

We’ll take a detailed look at your health history, current concerns, diet and nutritional needs. If you’ve previously worked with me through fasting, we’ll also consider your experience of fasting and refeeding.

Where useful, I may also draw on perspectives from traditional health systems such as Ayurveda and Chinese medicine, alongside modern nutritional approaches.

In more complex cases, I may suggest functional testing in areas such as gut or hormone health, allergies or genetic predispositions where this could add useful information to the nutritional picture. Given the additional cost involved, I never recommend testing routinely.

After the initial consultation, I’ll send you a written report containing specific dietary and supplementation recommendations.

Where possible, I prefer a natural, food-first approach rather than relying on a large number of supplements.

I often see clients arrive with such a long list of supplements that the supplementation protocol itself has become part of the problem rather than the solution. A smaller, more targeted supplement protocol also makes it easier to see what is genuinely useful, what is unnecessary and what may need adjusting.

In your follow-up consultation, we’ll assess your progress and developments since the initial consultation.

Your nutritional recommendations can then be adjusted appropriately.

Because nutritional needs can change over time, ongoing support can be particularly useful for people dealing with long-standing or evolving health concerns.

Initial online consultation (75–90 minutes) + 1 follow-up consultation (45 minutes)

Includes:

  • Detailed health questionnaire and diet diary
  • Comprehensive initial consultation
  • Personalized dietary and supplementation recommendations
  • Written report following the initial consultation
  • One follow-up consultation
  • Additional report noting any changes to the initial recommendations

The follow-up typically takes place between 2 weeks and 2 months after the initial consultation.

Initial online consultation (75–90 minutes) + 3 follow-up consultations (3×45 minutes)

Extended Nutritional Support includes everything in the Basic Nutritional Support package, with additional follow-up consultations spread over a longer period, typically 3–6 months. It is particularly suited to clients who want more sustained support, including those with long-standing or changing health concerns.

As your symptoms and nutritional needs evolve, we can review and adjust your diet along with any supplementation recommendations over a longer period of time.

45-minute online consultation

Available to current nutritional therapy clients who would benefit from additional support beyond their existing package.

Nutritional therapy may be appropriate if you:

  • Have completed a water fast and want support with your longer-term nutrition
  • Have already worked with me through fasting and want to continue your health journey
  • Have ongoing health concerns and want an individualized nutritional approach
  • Are tired of conflicting nutrition advice and generic diets
  • Have followed other dietary approaches that didn’t deliver results
  • Want personalised dietary and supplementation recommendations
  • Are preparing for a future water fast
  • Aren’t ready to fast yet, but want to begin working on your nutrition first

Whether you’re continuing after a fast, preparing for one, or starting with nutrition alone, we can begin with a detailed look at where you are now and what would be most useful next.

Do I need to have completed a water fast to work with you?

No. Many nutritional therapy clients do come to me after having worked together through fasting, but nutritional therapy is also available to people who aren’t yet ready to fast or who want to prepare nutritionally for a future fast.

What happens after my fast and refeeding period?

If you’ve worked with me through fasting, nutritional therapy can provide support for the next stage of your journey, helping you develop an individualized approach to diet and nutrition beyond the initial refeeding period.

Can I work with you if I have long-standing health concerns?

YYes. Many of my clients come with long-standing or complex health histories. During the initial consultation, we’ll look at your current concerns alongside your wider health history, diet and nutritional needs, and build recommendations from there.

Do you recommend supplements?

Where possible, I prefer to focus on food and improving the diet, rather than beginning with a large number of supplements. Where supplementation may be useful, I favour a smaller, targeted approach.

Will I need functional testing?

Not necessarily. In certain complicated cases, functional testing may be suggested to help resolve clinical uncertainties, but I never insist on testing.

Are consultations available internationally?

Yes. Nutritional therapy consultations are offered online, allowing me to work with clients worldwide.
