Who is Amanda?
Amanda King writes as The Metabolic Nutritionist on Substack, a weekly online newsletter with over 30,000 followers, committed to sharing research on off label drugs for cancer, supplements for cancer and dietary and naturopathic interventions in oncology. Her first book on off-label drugs for cancer will be published this fall.
Amanda’s background combines nutrition science with psychology. After earning her BSc through the Open University that combined Human Biology with Psychology and Counselling, Amanda King advanced her clinical training through the College of Naturopathic Medicine in London, first graduating as a Nutritional Therapist and then taking post graduate training as a Naturopathic Practitioner. Most recently, she graduated from the Practitioner Master Course in Integrative Metabolic Oncology with Metabolic Regen under Dr Nasha Winters, further deepening her expertise in terrain-focused cancer care.
Over the past decade, Amanda has honed her practice at the intersection of nutrigenomics, dietary interventions, methylation science and epigenetics, integrating advanced lab diagnostics with personalised nutrition, therapeutic ketogenic and ancestral diets, and targeted supplementation to optimise each patient’s metabolic landscape.
A certified nutrigenomics practitioner with training in Integrative and Gestalt psychotherapy , she is widely regarded for translating complex genomic and hormonal data such as DNA methylation panels and Functional Medicine testing into pragmatic nutrition and lifestyle protocols that address both biochemical individuality and psychological wellbeing.
In her integrative oncology nutrition practice, Amanda delivers bespoke protocols that weave together her expertise in the ketogenic diet, supplements, off label drugs, lifestyle optimisation, and evidence-based complementary therapies, empowering patients to navigate cancer with clarity and agency.
Committed to reshaping the dialogue around food as medicine, she collaborates with metabolic oncologists, functional laboratories and patient-advocacy groups worldwide to expand access to precision, nutrition-centred oncology care and to generate rigorous outcome data that will elevate the standard of integrative cancer support.

I’ve always been a nature girl with my feet in soil and my head in books, exploring the woods and devouring everything from Orwell to psychology texts and the classics. Initially, I followed the path to become a psychologist.
While studying psychology, I realised there was a gap: Why focus solely on the mind and neglect the body's needs? Why go through psychotherapy if your vitamin D and Omega 3 deficiency, shown to cause depression, was not addressed? I changed course and pursued a degree in Human Biology alongside Psychology and Counselling,
After earning my BSc in 2015, I immersed myself in self-development for four years, reading and learning from Dr Gabor Mate, Eckhart Tolle, Adyashanti, Marshall Rosenberg, Byron Katie, and Prof. Jordan Peterson, many of whom I had the pleasure of meeting along the way.
In 2022, I qualified as a Naturopathic Nutritionist at The College of Naturopathic Medicine. Early in 2024, I completed my postgraduate studies as a Naturopathic Practitioner (ND). In early 2025 I was informed that I had graduated from the Practitioner Master Course with the Metabolic Terrain Institute of Health, powered by Dr Nasha Winters.
People’s understanding of nutrition is changing. We truly are what we eat. With the right advice, nutrition and lifestyle, we can take control of our health. With a combination of blood tests, diagnostics, DNA methylation reports and consultations, I offer a powerful, personalised nutrition solution. This is the GOLD standard!
