Beating Cancer Metabolically: Gut Health, Repurposed Drugs, and Patient Empowerment with David A. Caravantes

Integrative Cancer Solutions with Dr. Karlfeldt

Show Notes

This episode of Integrative Cancer Solutions centers on David A. Caravantes, founder of the Beat Cancer Foundation, tracing how his father’s recovery catalyzed his mission to reframe cancer as a metabolic disease. Caravantes describes his path from breathwork and mitochondrial health to advocacy, arguing that conventional oncology often overlooks root-cause physiology. He situates his perspective amid recent public health controversies and his own family’s experience, using that narrative to underscore the urgency of patient education and informed consent in cancer care.

Caravantes distinguishes his foundation’s philosophy by emphasizing terrain-focused care: gut integrity, systemic pH balance, oxygenation, fasting, and whole-food nutrition as the biochemical conditions that “starve” cancer. He critiques standard-of-care modalities—chemotherapy, radiation, frequent biopsies—for damaging beneficial microbiota, driving malnutrition, and potentially spreading malignant cells. In his view, addressing metabolic dysfunction is the common denominator not only in cancer but across chronic disease, and it requires sustained lifestyle shifts alongside targeted therapeutics.

A major theme is the use of repurposed drugs and adjunctive modalities. Caravantes highlights agents such as metformin, ivermectin, doxycycline, and B17, as well as DMSO and exosomes, within protocols that aim to disrupt cancer metabolism and support immune regulation. He also references techniques like photodynamic therapy and therapeutic hypothermia. While critical of financial incentives that tether clinicians to narrow pathways, he frames his approach as complementary and integrative, seeking synergy rather than wholesale rejection of traditional tools.

Education and empowerment recur throughout the conversation. Caravantes encourages patients to become “CEOs” of their health—asking questions, evaluating trade-offs, and insisting on transparent risk–benefit discussions. He shares anecdotes of patients facing institutional resistance when they probe beyond standard options, arguing that public awareness, media literacy, and community-led knowledge-sharing are prerequisites for meaningful change. Success stories of remission within his community are presented as evidence for broader adoption of metabolic strategies.

The episode closes with actionable guidance: intermittent fasting within an eight-hour window, anti-processed-food habits, mineral-rich choices, and simple daily routines to nurture the body’s terrain. Caravantes is ultimately optimistic, forecasting that patient demand and continued clinical exploration of repurposed drugs will shift oncology toward more holistic, metabolism-centered care. He envisions Beat Cancer Foundation as a conduit for that transition—training patients and practitioners to collaborate on personalized, integrative protocols that prioritize both efficacy and quality of life.

David A. Caravantes explains how his father’s recovery led him to found Beat Cancer Foundation and champion cancer as a metabolic disease.

He argues conventional treatments like chemo and radiation damage gut health and nutrition, urging terrain-focused care that supports the microbiome and oxygenation.

The conversation highlights repurposed drugs (e.g., metformin, ivermectin, doxycycline, B17) and adjuncts like DMSO and exosomes within integrative protocols.

Education and patient empowerment are central, with a call for informed questioning and awareness of financial and institutional incentives in oncology.

Practical takeaways include intermittent fasting, whole-food nutrition, mineral support, and lifestyle shifts to create conditions that “starve” cancer cells metabolically.

What happens when the surgeon who has spent his career saving other people's lives finally has to save his own? In this episode of Integrative Cancer Solutions, Dr. K sits down with Dr. James C. Wittig, a nationally recognized orthopedic oncologist and sarcoma surgeon and the Founder and CEO of Mandala Medical Group, with roughly 10,000 procedures behind him. He explains why sarcoma in kids and teens so often gets dismissed as a sports injury or growing pains, and how limb-sparing surgery became the standard for most patients. Then he gets personal: thirty years of five-hour nights and eighty-hour weeks that ended in kidney failure and three stents. That experience is why he now brings hypnosis, meditation, neurofeedback and root cause testing like fasting insulin into cancer care. If you or someone you love is facing cancer, this conversation shows what whole-person care can look like from a surgeon who has been on both sides of it. Key Takeaways: Why sarcoma in children and teens gets missed as a sports injury or growing pains How chemotherapy response predicts osteosarcoma survival A sarcoma surgeon's wake-up call: 80-hour weeks, kidney failure and three stents Hypnosis, meditation and neurofeedback for stress and immune health during cancer treatment Fasting insulin, gut health and sugar as root causes in cancer care Schedule a Free 15-Min Cancer/Lyme Consultation at The Karlfeldt Center: 208-338-8902

What if the last piece of your cancer won't go away because it isn't physical at all? In this episode of Integrative Cancer Solutions, Dr. K sits down with Dr. Dana Flavin, a pharmacologist, toxicologist, biochemist and physician with 58 semesters of training behind her and more than 30 years of treating cancer patients around the world. Dana never set out to treat anyone. That changed in 1992, when friends in Ireland asked her to help a woman with advanced cervical cancer, no money and no insurance. Six months later the tumor was gone, and Dana has spent the decades since mapping how foods, nutrients, repurposed drugs and emotions each act on cancer biochemistry. She explains why a single-target drug so often stops working, and how shiitake and maitake mushrooms knock down the same immune-suppressing cells as cimetidine. She covers why a low-methionine, low-sugar, plant-based diet matters, and shares a stage 4 prostate cancer case where PSA dropped from 5,000 to 24.4 in 10 weeks. She also tells the story of a breast cancer patient whose last bit of tumor only cleared after she learned to love herself. If you or someone you love is fighting cancer, or working hard to keep it from coming back, this conversation gives you a lot to take to your care team. Key Takeaways: Why combination cancer therapy works when single-target drugs lead to resistance, from a colon cancer case with liver, lung and lymph metastases How shiitake and maitake mushrooms and cimetidine lower myeloid-derived suppressor cells so the immune system can recover A plant-based, low-methionine, low-sugar diet for cancer, plus cherries, raspberries and organic food Off-label drugs in a stage 4 prostate cancer case: PSA from 5,000 to 24.4 in 10 weeks with itraconazole, ivermectin, mebendazole and low dose naltrexone Emotional healing, forgiveness and staying in remission, and why unresolved hurt can bring cancer back

What if a blue-green algae could help your cells fight cancer the same way your own immune system does? In this episode of Integrative Cancer Solutions, Dr. K talks with Catharine Arnston, PhD, founder of ENERGYbits and author of the upcoming book Love Your Health to Bits with Algae. Catharine has spent years researching spirulina and chlorella, and she walks through why she sees cancer as a metabolic disease, one driven by damaged mitochondria, acidic cells, and the glucose that feeds tumor growth, a process known as the Warburg effect. She breaks down how superoxide dismutase protects your mitochondria from free radical damage, how chlorella clears the toxins that block your cell receptors, and how the blue pigment in spirulina called phycocyanin can trigger cancer cells to self-destruct while leaving healthy cells alone. If you or someone you love is trying to prevent, treat, or recover from cancer, this conversation gives you nutritional tools you can start using today. Key Takeaways: Why cancer is increasingly understood as a metabolic disease driven by the Warburg effect and glucose-fueled cell growth How spirulina's superoxide dismutase (SOD) content protects mitochondria from free radical damage as natural SOD levels decline with age Chlorella's detoxifying effect on cell receptors, and why clearing out cell-blocking toxins matters for nutrient absorption Phycocyanin, the blue pigment unique to spirulina, and its documented anti-angiogenesis effect and role in triggering apoptosis in cancer cells Why cutting simple sugars and carbs and increasing movement lowers the glucose available to feed cancer cells, tracked through the glucose ketone index (GKI)
