A Radical New Dietary Approach To Cancer Treatment

Episode 739 1h 28m


Over the years, it has become a widely held belief that cancer is predominately a genetic disease or simply the consequence of bad luck. An empowering evolution in cancer research, however, suggests we have far more control over our risk than previously thought.

On today’s episode, I’m excited to talk to Dr. Thomas Seyfried about the underlying causes of cancer and why addressing metabolic dysfunction is a very important and often overlooked area of its prevention and treatment.

We kick this episode off by talking about the metabolic theory of cancer and the role that oxidative stress, mitochondrial health, and glucose play in the development and progression of cancer.

Dr. Seyfried explains how cancer cells require glucose and glutamine to fuel their rapid growth and how depriving these cells of glucose using a ketogenic diet has shown remarkable results. When it comes to treating cancer, conventional medicine is good at cutting it, burning it, and poisoning it, but many doctors fail to treat or understand the root cause.

We talk about the limitations of conventional cancer treatment, and why diet and lifestyle strategies are an integral part of the solution for prevention and better treatment outcomes.

We also discuss Dr. Seyfried’s research and case studies with glioblastoma multiform (GBM) survivors, his research on using ketogenic metabolic therapy for dogs with cancer, and what the future of cancer treatment and prevention looks like. I hope you’ll tune in to this important conversation.

Introduction: Coming up on this episode of The Doctor's Pharmacy ...

Dr. Thomas Seyfried: Cancer is a disease of Western diets and lifestyles, because it never existed, nor does it exist in our closest primate relatives, the chimpanzee, which is about 98.5% similar to us in gene and protein sequence.

Dr. Mark Hyman: Welcome to Doctors' Pharmacy. I'm Dr. Mark Hyman. That's a pharmacy, a place for conversations that matter. And if you've had cancer, or anyone you've known or loved has had cancer, I think this is going to an important podcast, because we're going to talk about a very radically different view of how to approach cancer treatment beyond the usual slash, burn, and poison. Cancer is one of those diseases that..
