In this client Case Study, we were busy looking at ways to get valid feedback from the body despite not having the comprehensive thyroid markers.

The next place we looked was the Hair Tissue Mineral Analysis test. A Test that I wouldn’t run in isolation, but one that is very insightful when alongside other tests such as a comprehensive blood test, organic acids test and gut health test.

In particular, we were interested in one of Nicki’s Mineral Ratios. The Calcium to Potassium or Ca/K ratio.

Did you know it’s often more meaningful to look at ‘ratios’ of minerals, rather than just absolute levels of individual minerals?

This helps us understand the functions that they relate to. In the case of Ca/K this is Thyroid function.

It can scratch the surface of your physiology’s performance. With or without the presence of symptomology!

For example – this Ca to K ratio provides insight into Thyroid function for several reasons:

- Adequate Thyroid hormone levels can regulate calcium to required levels.
- High Calcium levels can affect the permeability and correct function of cell walls/membranes.
- Potassium is required to sensitise cells to the thyroid hormone.

As you can see on Nicki’s HTMA test the Ca/K ratio is high. It’s 29:1 and optimal is around 4:1.

So this is a case of far too much Calcium compared to Potassium levels (in the hair).

The complexity of hair tissue mineral analysis is not what we’ll go into in this case study, but here we had more markers of not only how the thyroid could be a piece of the puzzle, but also what may be the driver of the thyroid dysfunction.

Looking at how the mineral Calcium was being displaced and shunted out of the body (lost) would be a pivotal consideration for this case.

In part our client pre and post health challenges are down to the groundwork.

The foundational principles.

The none-marketable steps and discussions on identifying the dogma that dictated the lack of results so far.

And clearing it to pave the way to better processes and decisions!

None the less. These pre and post results make for an inspiring read.

From what I know about Abbi this was massive for her at the time. But I also know that this was just the beginning for her.

"Jack Walton guided me to get my body at it's optimal state, which I can say feels fantastic.

I am a 22 year old Australian girl living away from home in London. After months of travel, I was suffering with many different symptoms that were effecting my everyday life. I was searching for answers for a long time before I was introduced to functional medicine. Shortly after, I took the required tests and I identified H pylori.

It seemed it was going to be a long road ahead. There was a lot of work to be done to get healthy again. However Jack helped me on a weekly basis and using his thorough knowledge of functional medicine, we started to get my body on track again.

As the weeks went by, through a lot of fine tuning with the right nutrition, sleep & protocols, my body got itself into a more optimal state.

Over time, I felt more & more healthier & happier within myself.

I can't thank Jack enough for the help & support the he gave me throughout the 4 months. Not only did he clear me from H pylori, but he also taught me so much about my body that I can hold onto forever and put in place whenever I need. I've learnt so much about food & nutrition. I couldn't be happier with the outcome we achieved.

Thanks Jack. I appreciate your time & the effort you put into this."

If you read this client's full case study, there's a lot to cover - but these optimised 'Biomeaures' are the key to it all.

I appreciate this Case Study is quite long, but if you read through you’ll be able to appreciate the range of steps and angles that Nicki covered in order to support her cellular engines and metabolic rate.

Was it one thing in particular or a culmination of focus on nutrition, psychology, gut, nnEMFs, balanced exercise and movement, sleep, hydration etc?

Within 3 months this is what Nicki achieved:

Resting Pulse ranged from 58 to 59 (pre 44 to 57)

Resting Underarm Temperature ranged from 36.8 to 37.0 (pre 35.1 to 36.4)

Massive Improvements! 😀

When you align these with how she was feeling pre and post, she now has much greater clarity on what her physiology can tell her about when she is at her best.

We'll address your main health goals as the highest priority, but won't lose sight of how it will be connected to all other functions in the body.

When you leverage that there's a great chance that many things will change.

We don't treat Lichen Sclerosus or claim to be experts in it. We've not built a brand around the niche either. This already exists and is available as needed.

That's not our remit.

When we are working with someone like our client John, we are applying the Functional Health approach. We work with your system-of-systems. It's not 'better'. It's simply different.

If you are looking to leverage a chronic health challenge, let us know and we can find out more and then give you some insight.

“For the last 10 years I had been treating a diagnosis of Osteopenia with a popular conventional medication (a bisphosphonate), but as it was still getting worse, my Endocrinologist wanted to increase the treatments. I consulted two specialists, but decided that I would prefer to avoid medications and the side effects where possible.

I’d worked with several practitioners, running various tests and applying steps like nutrition and supplementation. These all helped me make some general improvements, but then I started experiencing more acid reflux and one of my tests had identified an H pylori infection and yeast and fungal overgrowth.

That’s when my research brought me to the work that Jack Walton does. And most interestingly how the various health challenges and symptoms I was having could be linked in some way.

Part of my concern about H pylori was that it was contagious and how that could affect my family. So as part of the coaching support we ran tests to screen my husband, son, daughter and son-in-law. We live in Texas, so it was fantastic that we could access this type of functional lab testing via Jack.

My daughter’s test came back positive for H pylori and she had been ill for many years, since a child. So, whilst we both had quite different situations, symptoms and presentations, both my daughter and I began working with Jack. There were some tricky adjustments to foods and some supplementation, but we worked hard to put everything in place.

The weekly support and coaching were an anchor that helped reassure us that we would be able to deal with this. I was quite alarmed at the beginning, but through conversation with Jack, was able to put my body's health in a better perspective and deal with the findings as part of a larger goal. That lowered if not eliminated the stress of having the h. pylori and yeast and I gained confidence in dealing with and in trusting that I could influence my body's health.

Given the situation I was expecting at least a year of treatment. Yet to our amazement after 3 months our retests showed both negative for H pylori and the yeast and fungal overgrowth and most of our symptoms were alleviated.

We are both very grateful for Jack's help and it is with great appreciation that my daughter and I say ‘thank you Jack’.”

Nicki’s (case study) pre underarm temperatures were 35.1 to 36.4 which fall significantly below the optimal level.

Despite the many lab test profiles we can run, this one finding is as insightful as any!

This low temp would suggest a low metabolic rate.

And therefore, explain a lot of what she was experiencing.

For our client, this was a fantastic opportunity. Great insight, with which she could track and empower some changes.

Take a look at what she achieved.

We ran a whole webinar and an in-clinic session on the influence of dogma, one-size-fits-all, and the this-for-that approaches in nutrition. But why?

Yes we're fascinated in this aspect of nutrition and the health industry. But why is this so important that it's part of our coaching with our clients and membership group?

Short Answer - is that it is so important due to the benefit of addressing it as early as possible.

Address it, understand it, action it - build on it.

I think that if we truly value and have a goal to identify and progress towards our individual needs around nutrition, then this is going to be a hard road to travel if we haven't done this work.

The sheer level of the resources (time, changes, effort, finance, education) people put into their nutrition raises the question as to whether these are wise investments?

After all - the point of making all these changes is (usually) related to a goal around improving health and wellbeing.

But are the changes yielding the results?

Can they be accurate and effective nutrition changes if they are actually a stab in the dark?

And that doesn't mean we haven't researched it. it doesn't mean that it isn't valid on some level.

It simply means that it may not be suitable for us as a complete individual.

The more we are directed by the extrinsic nature of the one-size-fits all (as convincing as it may be presented) - the less likely we will be delivering to or own needs.

So - addressing it early simply and sensibly means that any level of effort or resource you put towards your nutrition stands a better chance of yielding results.

It's more efficient and accurate.

That bit more intrinsic.

More likely to help you achieve your goal.

We coach and class it as an early and Foundational Step in our program.

If you are interested in hearing how we worked with Carly to achieve her results then just drop us a message.

The 'Functional' approach isn't the be-all-and-end-all. It's not everything. It's not better or worse.

But it's remit and questions that it asks certainly is.

If you are struggling with gut health, digestive infections, pain - just let us know.
