Professor Thomas Seyfried, a biologist and expert in genetics and biochemistry, challenges the prevailing view that cancer is primarily a genetic disease. He argues that cancer is fundamentally a metabolic disorder, driven by lifestyle factors that disrupt mitochondrial function. Seyfried emphasizes the potential of metabolic therapy, which involves restricting glucose and glutamine while increasing ketones through diet and lifestyle changes, as both a preventive and therapeutic approach. He highlights the importance of maintaining mitochondrial health through exercise, fasting, and a low-carbohydrate diet, suggesting that these strategies could significantly reduce cancer incidence and mortality.
- Thomas C. Seyfried, a professor of biology, argues that cancer is a metabolic disorder rather than a genetic disease.
- He has spent 30 years gathering scientific evidence on the origins and prevention of cancer.
- Cancer is getting worse globally, with no significant advances in reducing death rates.
"All major cancer research people think cancer is a genetic disease. You believe otherwise. It's not whether you believe; it's what the data tell us, and the evidence is massive to support that cancer is a metabolic disorder."
- Seyfried emphasizes that scientific data supports the view of cancer as a metabolic disorder, challenging the prevailing genetic perspective.
Global Cancer Statistics
- Cancer is a growing global epidemic, with millions of new cases diagnosed annually.
- In the United States, nearly two million new cases are diagnosed each year, with 1,700 people dying daily.
- By 2050, cancer rates are expected to be much worse than today.
"We have almost two million new cases diagnosed per year in the United States, and we have 1,700 people a day dying from cancer in the United States."
- Seyfried highlights alarming statistics to emphasize the severity of the cancer epidemic.
Common Types of Cancer
- Lung cancer remains the most prevalent type of cancer for both men and women.
- Other common cancers include pancreatic, breast, and colon cancer, all of which are on the rise.
"Lung cancer has always been the number one, but we have pancreatic, breast cancer, colon cancer. These are all on the rise."
- The rise in various cancer types is attributed to lifestyle and environmental factors.
Misleading Advances in Cancer Treatment
- The reduction in cancer deaths in the U.S. is largely due to anti-smoking campaigns, not treatment advances.
- Claims of major advances in reducing cancer death rates are misleading, as they are based on prevention rather than treatment.
"It was clearly a prevention; it had nothing to do with a treatment. It had to do with prevention that was giving the, oh, we've made major advances in reducing cancer death rate."
- Seyfried criticizes the portrayal of cancer treatment advancements, emphasizing prevention over treatment.
Fermentation and Cancer
- All cancers share a common dependency on fermentation, a process of obtaining energy without oxygen.
- Cancer cells rely on glucose and glutamine for energy, even in the presence of oxygen, due to defective mitochondria.
"The cancer cell lives in cyanide. Cyanide does not kill a tumor. Warberg showed this a long time ago, and we've also shown the same thing in our lab."
- Seyfried explains how cancer cells survive in conditions that would typically be lethal to normal cells, highlighting their reliance on fermentation.
Historical Perspective on Cancer
- Otto Warburg first identified the metabolic nature of cancer in the 1920s.
- Warburg discovered that cancer cells consume less oxygen and produce lactic acid, indicating a shift in energy metabolism.
"Warburg was taking slices of all kinds of human and rat mouse tumors and slicing them up, and he noticed something really strange about these cancers. They take in less oxygen compared to the normal tissue from which they came."
- Seyfried credits Warburg's pioneering work in identifying the metabolic characteristics of cancer cells.
- Metabolic therapy involves restricting glucose and glutamine while transitioning the body to use ketones, which cancer cells cannot metabolize.
- This approach can potentially manage cancer without toxicity and reduce the risk of cancer development.
"A solution to the cancer problem to manage cancer without toxicity is to simultaneously restrict the two fuels that are needed to drive this disregulated growth while transitioning the whole body off to a fuel that the tumor cells can't use, which is fatty acids and ketone bodies."
- Seyfried outlines a therapeutic strategy that targets cancer's metabolic vulnerabilities.
Evolutionary Insights into Cancer
- Cancer was rare in traditional societies and among animals that consume natural diets.
- Modern lifestyle and diet contribute significantly to the rise in cancer rates.
"Albert Schweitzer, the great humanitarian physician, went to Africa and looked at Africans that were living according to the traditional ways, and he said one of the weirdest things, they don't have cancer."
- Seyfried suggests that modern lifestyle changes have disrupted natural metabolic states, leading to increased cancer prevalence.
Role of Exercise in Cancer Prevention
- Exercise helps reduce blood sugar and glutamine levels, which are essential for cancer cell growth.
- It also promotes the burning of ketones, enhancing mitochondrial efficiency and overall energy metabolism.
"Exercise lowers blood sugar, you know, and also lowers glutamine. So the two fuels that are driving, now we can't completely remove glutamine by exercise, that's for sure."
- Seyfried advocates for exercise as a preventive measure against cancer by targeting metabolic pathways.

"You put yourself in a diet and lifestyle that puts you at risk for damage to oxidative phosphorylation and the transition from one form of energy to a fermentation energy."
- Describes how lifestyle choices can lead to mitochondrial damage and cancer development.
"It's very hard to really chronically damage mitochondria. Mitochondria are a tough organelle."
- Suggests that while mitochondria are resilient, chronic abuse can lead to dysfunction.
Carcinogens and Environmental Factors
- Carcinogens like microplastics and chemicals can cause cellular changes leading to cancer.
- The body's immune response to foreign particles can inadvertently cause inflammation and damage to mitochondria.
"The one that was most interesting was the talcum powder one. How does talcum powder cause ovarian cancer?"
- Discusses how foreign particles like talcum powder can trigger inflammatory responses leading to cancer.
"Microplastics are now being looked at, but it's very hard to really chronically damage mitochondria."
- Highlights the emerging concern of microplastics as potential carcinogens.
Cancer Theories: Genetic vs. Mitochondrial
- Debate between the somatic mutation theory (cancer as a genetic disease) and the mitochondrial metabolic theory.
- Evidence suggests that mitochondrial dysfunction, not genetic mutations, is the primary cause of cancer.
- Current cancer research and treatment are largely based on the genetic theory, which may be flawed.
"According to the somatic mutation theory of cancer, mutations in the nucleus lead to disregulated cell growth."
- Explains the traditional view of cancer as a genetic disease.
"If you take the tumor nucleus out of the cell and put it into a normal healthy cell, everything is fine."
- Provides evidence against the genetic theory, suggesting mitochondrial dysfunction is the root cause.
Resistance to Paradigm Shifts in Cancer Research
