Ever felt like you’re waiting to feel well?

Not just so you can end the daily struggle of juggling pesky, painful symptoms and free yourself from feeling perpetually exhausted (even when you’ve just woken up) …

… But so you can start living your life again. Because right now, it feels like your health is holding your life to ransom and preventing you from pursuing the dreams, goals, opportunities and experiences you deserve.

And that wait for wellness can feel especially eternal when,

Your laboratory tests and investigations from your doctor say everything is “normal”, but you know everything is far from normal.

Your doctors maintain that medicine and prescriptions are the best and only path forward.

You’re told to “wait and see” what happens rather than being given the tools you need to feel empowered and in control of your health.

You look to health influencers for solutions but only get #detoxchallenges and generics that don’t touch the sides of your unique health issues.

We’re patient folk here at The Thrive Practice. But, like you, we get frustrated when we see humans struggling with short-term solutions that promise managing symptoms is the same as resolving the issue.

It isn’t.

There is usually more than one cause for every chronic health concern. Wellness can’t be restricted to weight.

Cultivating good health is about more than food and fitness. And healing your health shouldn’t solely rely on a coin toss between pharmaceutical pills for your ill.

Which is why we’re determined to provide you with the customised data-driven solutions you need to get to the root of your health problem, so you know exactly how to take care of yourself.

We understand the intricate rules of what creates – and destroys – health on a dynamic, integrated and interconnected level.

Imagine if…

Your symptoms no longer felt like one of humankind's most unsolved mysteries and, instead, you had the data, information and expertise backing you to feel confident that you knew exactly what was going on inside your body.

You didn’t feel trapped and thwarted by your health concerns and could see the light at the end of the tunnel (and a life free from the pain, discomfort and frustration you’re experiencing).

You had a practical, proven and data-driven roadmap for creating changes that repeatedly provoked remarkable results.

You could reduce your prescriptions and pills by relying on innovative science to resolve your health concerns and restore healthy function.

You no longer felt alone in your health journey but knew you could depend on the support of an expert committed to keeping you aligned, accountable and on track with addressing your health concerns and optimising your health for the long term.

Our proven approach to wellness not only reveals the root cause of your health concern and restores your health but also helps you prevent disease in the future. 


Our Rebalance Wellness Programme will take your health from where you are to where you want to be so you can take your life off hold and make miracles happen.

Success stories

Shifting Painful Problems Into‍ Unlimited Possibilities

The best investment I’ve made in my health! I reached out to Leah after experiencing stomach issues for a number of years. She took onboard my concerns and very quickly got the ball rolling. Her response to emails/messages were always prompt and she exceeded what I initially expected. Not only did she design a custom plan for me, but Leah also made sure I was involved in the process. If there was anything I found difficult, she would find a way to accommodate and make it even more tailored - without hesitation. Fast forward three months and I can honestly say this was the best investment I’ve made in my health thus far! I have finally got concrete evidence for the root of my problems and my symptoms are improving daily. This is to the credit of Leah and her hard work. My only regret is not reaching out sooner.”


Thrive practice will take you on a journey to better health. I have worked with Leah for 6 months now and I have learned a whole lot of useful information about my health. I have had quite a few random symptoms that I knew deep down were part of one big issue. I gave up on GP's, as all I could hear were excuses of why I felt unwell and no investigation. I did not want to end up with a serious chronic disease so took matters into my own hands and found Leah. Leah takes all my worries seriously and works to find out the reasons why I am feeling constantly run down and weak. My health journey is a long one but I am hopeful that my best and healthiest self is just around the corner - she just needs a mindful helping hand.



Meet Your Practitioner

Leah de Souza-Thomas is a biomedical scientist, public health epidemiologist, health improvement consultant and founder of The Thrive Practice.

After 19 years of exploring and advising on contagious diseases and chronic conditions at a local, regional and national level across health protection, health improvement and healthcare public health, Leah came to a shocking revelation: Conventional approaches to managing not only chronic diseases but our wellness simply weren’t working.
And she wasn’t going to sit on the sidelines and wait for it to get worse.

In addition to her Biomedical Sciences (BSc), Modern Epidemiology (MSc) and Public Health (MPH) degrees, Leah has completed numerous studies in lifestyle medicine, including the Royal College of General Practitioners accredited course Prescribing Lifestyle Medicine, the Institute for Functional Medicine’s Applying Functional Medicine to Clinical Practice (AFMCP), all six Advanced Practice Modules (covering bioenergetics, cardiometabolic, environmental, gut, hormone and immune health), and the Therapeutic Food Plans course.

Leah knew we needed to think differently about our approach to solving the chronic health crisis. Today, it’s this new – data-driven – approach combining her public health expertise and biomedical training with science-based lifestyle medicine that she successfully uses with clients to transform their health and lives.

Frequently Asked Questions

Are functional health tests included in the programme?

The DUTCH Plus test is not included in the programme but may be recommended for you and will be sent to your home address if you choose to add them to your programme. If your intake assessment or test results suggest the need for further testing, an email/message will be sent to you explaining the rationale behind the recommendation and details of costs. It is entirely your choice whether to proceed with this recommendation or not.


Are supplements included in the programme?

We provide personalised, professional-grade supplement protocols based on your test results and intake assessment. Given the level of personalisation in this programme, it would not be appropriate to include supplements in this programme.

I’ve seen free hormonal health programmes online, and this feels expensive.
This is true – there are a lot of hormone resources available online. While you could find temporary relief from one-size-fits-all social media or Google solutions, Rebalance aims to provide you with knowledge and understanding of your body, as well as a completely personalised healing journey so you can upgrade your life, and feel lighter, happier and more energetic.
What if I invest in this, and it doesn’t work? Do you guarantee my results?
I know you’ve tried a lot of things to try and fix the way you’ve been feeling. I know you have the best intentions and that you’re willing to do whatever it takes to feel better. You know these symptoms are all caused by something, but no one takes you seriously. I promise this programme is different from all the others out there.

That said, while I fully believe and stand by this holistic scientific approach and your body’s innate ability to heal, every human is different. It would be wrong and irresponsible to speak in absolutes when it comes to the body. That said, Rebalance is a comprehensive scientific approach designed with your specific needs in mind, so you just need to follow your programme to see results.

I’m too busy to make lifestyle modifications. Wouldn’t it be easier just to take the pills?
It may be easier to take the pills to manage the symptoms you’re experiencing, but pills won’t uncover what’s causing the problem and address it; pills will just mask the symptoms, and you’ll need to take them long-term to manage.

The truth is the only way to address your symptoms and concerns is to correct them from the inside out. That’s why Rebalance exists. This programme was made with this knowledge in mind.

The problem wasn’t there before; it may go away.
Your hormones are in crisis. Your body is showing you signs that it needs help: you’re tired all the time, you can’t dredge up the energy you need to get on with your day, you’re losing your hair, and your PMS symptoms are unbearable. You’re moody and can’t enjoy life. You’re on the verge of giving up and accepting that this is just how life is for everyone. You’re taking medication daily and dealing with the symptoms with little to no relief. It doesn’t have to be this way.

Your symptoms are your body’s way of demanding help. Consider it a warning sign. It’s time to get to the root of the problem with this game-changing programme. You will finally feel like you know you should. Your body will carry you throughout your whole life – you owe it to yourself to make sure it’s in the very best condition.
