— Dr. Jen Levin
When I received my Stage 4 Ovarian Cancer diagnosis at 19, one of the most shocking realizations wasn’t about my physical condition — it was recognizing how completely I had abandoned myself.
For years, I had been everyone’s emotional caretaker. I said yes when I meant no. I absorbed other people’s stress until my nervous system was constantly overwhelmed. I genuinely believed that putting everyone else first made me a “good person.”
What I didn’t know then — but what our research now proves — is that this pattern was actively blocking my body’s ability to heal.
Through our collaboration with Liber8, we have analyzed over 180,000 data points from women with cancer and chronic illnesses. The results are both heartbreaking and hopeful:
→ 57% of women in our studies
struggle with putting their own needs first
→ 83% of those same women
who learn to honor themselves
see measurable health improvements
This is not just about feeling better emotionally. When women learn to set loving boundaries and advocate for themselves, they report:
- Dramatically improved energy levels
- Better treatment tolerance
- Enhanced emotional resilience
- Reduced feelings of fear
- Higher quality of life throughout healing
If you have been doing “everything right” but still struggling with chronic symptoms, there is a missing piece.
I remember the physical anxiety I felt when I even thought about disappointing someone. My body would react like I was in actual danger.
What I have learned is that these responses can be completely rewired.
Your nervous system can learn that advocating for yourself is not only safe — it is essential medicine.

A Closing Thought
I leave you with these words from Viktor Frankl, a man who found meaning amidst unimaginable suffering:
When we are no longer able to change a situation,
we are challenged to change ourselves.
Let us lean into the transformative power of gratitude — not as a fleeting feeling, but as a daily practice. In a world divided, let us remember that gratitude unites. In times of darkness, let us trust that the light is always within reach.
From all of us at the Metabolic Terrain Institute of Health, we wish you and yours a time filled with presence, meaning, and gratitude.
At the age of 19, I was diagnosed with end-stage ovarian cancer and given 3-6 months to live. Crippled with pain, nausea, infections, malnourishment, and muscle wasting, I was un-insured and out of options. But I was also young, naïve, and stubborn. It was up to me to dig deep and find hope. The diagnosis of terminal cancer suddenly shook me awake.
Since that diagnosis in 1991, the years have unfolded as a journey that I continue to this day. What began as a pursuit to heal my own body has evolved into a global mission to transform cancer care.
From Survivor to Physician
I started naturopathic medical school five years after receiving my terminal diagnosis of cancer. It offered me a safe haven to explore the basic sciences, nutrition, lifestyle, supplements, intravenous protocols, laboratory assessments, mind-body healing, and homeopathy. Because of my own health issues, I applied everything I was learning to myself before trying it with patients.
During school, I vowed that I would never work with cancer patients. But within my first few months in private practice, I was blessed with the opportunity to support a cancer patient in miraculous ways. My career had chosen me.
From my work with thousands of cancer patients over the years, I have learned that there is no magic pill. Cancer is not a single disease and has no single cure. We need to listen deeply to the cells of the body (with labs, molecular profiling, tissue assays, epigenetic testing, and more). We need to metabolically support the body’s terrain (with oxidative therapy, therapeutic diet, stress reduction, and other therapies). When we do these things, the body can survive and thrive.
It was the decades of experience with my patients that led to the writing of The Metabolic Approach to Cancer. It is my hope that the book will not only share what I have learned along the way but also inspire others to continue to dig deeper — to address the collection of hundreds of illnesses that make up cancer and chronic disease.
Over the last few years, I have travelled the world to share the message of the metabolic approach to cancer. I have spoken with audiences of incredible physicians who have committed their careers to supporting patients with cancer. Through these experiences, I have learned an important lesson: doctors need support too.
I offer doctor-to-doctor consultations and intensive mentorships for clinicians who want to more deeply understand metabolic and integrative approaches to cancer. There are so many nuances to implementing an integrative and metabolic approach with cancer patients.
When we put our heads together, we can achieve better outcomes. I am here to guide clinicians to become masters of the metabolic approach.
I am the Executive Director of the Metabolic Terrain Institute of Health. The mission is to build a residential integrative oncology hospital and research institution in Southeast Arizona … it is now underway.

What is Integrative Metabolic Health Care?
Integrative Metabolic Health Care is a patient-centered approach that goes beyond symptom management to address the root causes of disease. It merges metabolic science, functional medicine, and integrative therapies to optimize health at a cellular level, focusing on the body’s ability to heal and regenerate.
By understanding the Terrain Ten™ approach — a framework that evaluates key health factors such as inflammation, detoxification, hormone balance, and mitochondrial function — practitioners can create personalized care plans that enhance overall well-being and support disease prevention.
This approach is particularly effective for chronic conditions, cancer support, and metabolic dysfunction, utilizing evidence-based interventions like nutrition, fasting strategies, lifestyle medicine, targeted supplementation, and lab-driven insights to restore balance.
At Metabolic Regen, our courses provide clinicians, health advocates, and medical professionals with the tools to integrate metabolic health principles into their practice — transforming the way we understand and treat disease
At the Metabolic Terrain Institute of Health (MTIH), we are passionate about offering diverse educational resources tailored to various health professions. Our programs include specialized courses for clinical practitioners, allied health professionals, caretakers, and health coaches. Additionally, we provide introductory courses on the metabolic approach to health and wellness, complemented by free public interviews with Nasha.

Dr. Winters has recently published a new book, Mistletoe and Emerging Future of Integrative Oncology.
Human disease is an elaborate dance between behavior, our environment, and chance. Medicine tries to tame human disease with science, but when our knowledge falls short, disease wins. This is too often the case with cancer. We spend billions of dollars each year trying to better understand it and develop tools to ease its effects.
Today, many allopathic medical practitioners are beginning to seek out a greater connection with holistic and integrative approaches. The authors of this book introduce one specific therapy and make a case for integrative health in general, including anthroposophically extended medicine, naturopathy, and other holistic approaches.
Mistletoe therapy has long been considered a viable treatment for cancer by the European medical community and is beginning to gain recognition in North America as well. The mistletoe plant possesses many remarkable properties. As a therapy, it represents a rediscovery of ancient wisdom and shows us how the science of modern medicine might expand its reach and reconnect with a more human-centered medicine.
The book was structured following the syllabus for a three-day practitioner training hosted by the Physicians’ Association for Anthroposophic Medicine (PAAM). The chapters highlight several of our key lectures in a condensed form. The book serves as an introductory summary of ― not a replacement for ― those intensive professional trainings.
While this book should not be regarded as a treatment or diagnostic manual, it is intended to both prepare practitioners to begin mistletoe therapy training and to make this information available in an accessible form to anyone interested in learning about this approach to treating cancer.
The Science of Terrain-Based Medicine
Metabolic and terrain-based medicine is not a fleeting health trend or a collection of anecdotal success stories. It is a scientifically driven, systems-based approach to health optimization and disease prevention. At its core, it focuses on:
- Metabolic flexibility and mitochondrial function as the foundation of health.
- Epigenetics — how environment and lifestyle shape genetic expression.
- Objective testing to guide personalized interventions.
- Root-cause healing rather than symptom treatment and suppression.
Unlike conventional treatments that focus primarily on detecting and eliminating tumors, the terrain approach asks: Why did the cancer arise in the first place? If we don’t change the internal environment that allowed cancer to grow, recurrence is not a question of if — but when.
The Terrain Ten™ framework recognizes that health is a result of multiple interconnected factors:
- Epigenetics: Lifestyle and environment influence gene expression.
- Glycemic Control & Nutrition: Cancer thrives in a sugar-fueled metabolic state.
- Environmental Toxins: Chemical and heavy metal exposure disrupts cellular health.
- Microbiome Health: The gut-immune-brain axis plays a critical role in cancer development.
- Immune Function: Strengthening the immune system to prevent and reverse disease.
- Inflammation Regulation: Chronic inflammation fuels cancer growth.
- Oxygenation & Circulation: Mitochondrial energy production is key to healing.
- Hormonal Balance: Endocrine health affects cancer risk.
- Stress & Circadian Health: Dysregulated stress responses impair immune function.
- Mind-Body Connection: Psycho-neuro-immunology is real—emotions influence biology.
None of this is theoretical. It is grounded in decades of metabolic and epigenetic research, as well as thousands of case studies showing profound healing when these principles are applied.
The Failure of Conventional Medicine to Address Root Causes
Despite advances in early detection and treatment, cancer rates continue to climb. The problem isn’t just that we lack true cures — it is that the current model ignores prevention entirely.
Most cancers — up to 90 percent — are caused by environmental and lifestyle factors. We know this from extensive research on:
- Diet & Nutrition: High sugar intake, processed foods, and nutrient deficiencies create a biological environment where cancer thrives.
- Toxic Exposure: Pesticides, endocrine-disrupting chemicals, heavy metals, and pollutants are linked to cancer development.
- Chronic Stress & Trauma: Long-term stress weakens the immune system and contributes to systemic inflammation.
- Metabolic Dysfunction: Cancer is increasingly recognized as a metabolic disease, driven by mitochondrial damage and glucose dysregulation.
Yet, mainstream narratives continue to focus only on detection and treatment, not prevention. The assumption is that cancer is either a genetic inevitability or simply random bad luck. This not only contradicts the evidence but actively disempowers patients from taking control of their health.
While mainstream medicine dismiss alternative cancer healing as anecdotal, thousands of cases prove otherwise. Decades of metabolic and epigenetic research, alongside thousands of case studies, confirm these principles.
Why This Matters More Than Ever
The legitimacy of metabolic and terrain-based medicine is scientifically supported. Important questions include:
- Why are metabolic diseases, including cancer, rising despite extensive research funding?
- Why is preventive medicine marginalized?
- Why does conventional medicine overlook mitochondrial and metabolic health?
Instead of dismissing terrain-based medicine, skepticism should target mainstream medicine’s persistent neglect of root causes.
Guidance for Providers
Providers practicing metabolic and terrain-based medicine will face skepticism. Engage skeptics productively:
- Stay Grounded in Science: Terrain-based medicine is supported by decades of research, testing, and clinical outcomes.
- Invite Curiosity, Not Conflict: Encourage dialogue by asking skeptics, “Are you open to examining the research?”
- Shift the Narrative: Redirect discussions toward the genuine crisis — the increase of metabolic diseases and conventional medicine’s shortcomings.
Guidance for Patients
Patients can empower themselves through knowledge:
- Educate Yourself: Understand interconnected health factors like diet, stress, toxins, and emotional well-being.
- Ask Critical Questions: Investigate why cancer develops and explore preventive strategies.
- Advocate for Personalized, Holistic Approaches: Move beyond symptom management to root-cause solutions.
Final Thoughts: Focus on What Matters
Healthy skepticism is essential in science — but we must question the right things. Instead of dismissing metabolic and terrain-based medicine as mere trends, let’s discuss the alarming rise in chronic disease, the neglect of root-cause medicine, and actionable solutions to achieve lasting health transformation.
