Find a Fluxable Practitioner
There is growing interest in the role metabolism plays in cancer biology, and many people want to understand how nutrition and lifestyle might contribute towards prevention and recovery, as well as supporting wellbeing alongside medical care during cancer treatment.
It’s important to note that nutritional therapy does not aim to diagnose, treat or cure any disease, including cancer but to support resilience, health and homeostasis of the body. The practitioners listed below (in alphabetical order) have trained in the Fluxable Framework and are able to provide metabolic support at different stages of the cancer ‘journey’. You should check in with your chosen practitioner about their experience, and satisfy yourself that they have all the training and qualifications you expect. You may also wish to search on the BANT register of trained cancer practitioners here. Some Fluxable Practitioners are on both; most have invested in a wide range of training including other excellent integrative cancer courses.
Please note that not all practitioners listed hold a medical qualification, and it remains the law in the UK that no one other than a registered medical doctor can advise on the treatment of cancer or prescribe remedies for it. You should always discuss any complementary care choices with your medical team in order to avoid undermining your treatment. This is a highly sensitive, deeply personal, and tightly regulated area of practice.
Scroll to the bottom if you are an integrative oncology practitioner and wish to be added to the register.
Catherine Arnold, Catherine Arnold Nutrition
I am a Registered Nutritional Therapist and certified Functional Medicine Practitioner with 13 years clinical experience, specialising in gastrointestinal health, hormone health and stress resilience. I have 10 years’ experience supporting people affected by cancer under the mentorship of a leading Nutritional Therapist and Functional Medicine practitioner in integrative cancer care. In 2007 I supported my husband through leukaemia, an experience that inspired my career. He is 19 years in remission.
While I complete the BANT Cancer Accreditation, I am not currently working with active cancer diagnoses. Instead, I support clients with cancer prevention and those who have completed treatment and been given the all-clear, helping them optimise their health, recovery and long-term wellbeing. I use functional testing such as stool tests, life code nutrigenomics tests and hormone tests alongside diet support to reach a goal of optimal health.

My aim is to take away the confusion of conflicting health advice, leaving you with one less thing to worry about. I enjoy supporting men and women who are ready to make positive, lasting changes to improve, restore and protect their health, either online or in person.
My own health experiences have shaped the way I practise. I have overcome a number of health challenges, including simple cystic hyperplasia (pre-cancerous changes to the uterine lining), through nutrition and lifestyle changes alone. Supporting my sister, who lived with multiple myeloma for 10 years beyond her original life expectancy, has also given me a personal understanding of the impact cancer can have.
I hold a First Class Honours degree in Nutritional Therapy with additional specialist training in cancer and nutrigenetics. Where appropriate, I use advanced functional medicine testing, including nutrigenomics, to build a detailed understanding of your health and guide a personalised nutrition and lifestyle programme, working alongside your oncology team.

You won’t find overly restrictive diets or expensive supplement stacks here; instead, we focus on nourishing strategies that fit seamlessly into your everyday life.

I carefully tailor every recommendation around your medical treatment plan and encourage open dialogue with your oncology team so you always feel safe and empowered. I have a particular passion for supporting clients once active treatment has ended, helping you rebuild vitality, restore confidence, and navigate long-term health with clarity and ease so you can truly thrive in life beyond cancer.
