Boston College Professor Dr. Thomas Seyfried: "These foods are fuelling cancer!"

Ever wondered if cancer is really just a genetic disease? Dr. Thomas Seyfried challenges the conventional view and reveals how mitochondrial dysfunction is at the heart of cancer. Discover how metabolic therapies like ketogenic diets and fasting can offer powerful, non-toxic solutions for cancer management.

Frequently Asked Questions (FAQ)

  1. What challenges the view of cancer as a genetic disease? Dr. Seyfried argues that cancer is primarily a metabolic disorder, not solely caused by genetic mutations. He points out that cancer cells heavily rely on fermentation for energy (even with oxygen present, known as the Warburg effect), which is linked to mitochondrial dysfunction. Research suggests genetic mutations might often be a consequence, rather than the primary cause, of this underlying mitochondrial damage.

  2. How does mitochondrial dysfunction contribute to cancer? When mitochondria are damaged, cells are forced to switch to less efficient energy production methods, primarily fermentation. Cancer cells thrive on the byproducts of fermentation, particularly glucose and glutamine. This metabolic shift fuels cancer growth, proliferation, and resistance to cell death.

  3. What damages mitochondria? Mitochondrial damage can result from various factors, including exposure to carcinogens (radiation, chemicals), chronic inflammation, hypoxia (low oxygen), viral infections, and lifestyle factors like poor diet (high intake of processed carbohydrates and sugars), lack of exercise, chronic stress, and inadequate sleep.

  4. What is metabolic therapy for cancer? Metabolic therapy aims to exploit the metabolic inflexibility of cancer cells. It primarily involves strategies to restrict the fuels cancer cells rely on (glucose and glutamine) while promoting the production and utilization of ketone bodies (derived from fats), which most cancer cells cannot efficiently use for energy. The ketogenic diet is a central component of this approach. The goal is to weaken cancer cells, making them more vulnerable to natural cell death processes or conventional treatments.

  5. What is the GKI and why is it important? The Glucose Ketone Index (GKI) is a single number representing the ratio between blood glucose and blood ketone levels. It provides a biomarker to gauge the state of metabolic therapy. A lower GKI (typically below 1.0 or 2.0, depending on the context) indicates a deeper state of therapeutic ketosis, suggesting a metabolic environment less favorable for cancer growth and potentially beneficial for cancer management and prevention.

  6. How effective is metabolic therapy? Growing evidence from pre-clinical studies and some clinical case reports suggests that metabolic therapy, often used alongside standard care, can help shrink tumors, slow progression, extend survival times, and potentially enhance the effectiveness of traditional treatments like chemotherapy and radiation by sensitizing cancer cells. However, large-scale clinical trials are still needed.

  7. What practical steps can improve metabolic health and potentially reduce cancer risk? Key steps include regular exercise, reducing the intake of processed carbohydrates and sugars, increasing consumption of healthy fats, considering intermittent fasting or time-restricted eating, managing chronic stress effectively, and prioritizing sufficient high-quality sleep. These actions support overall mitochondrial health and create a less favorable environment for cancer development.

  8. Where can one learn more about Dr. Seyfried’s work? Dr. Seyfried encourages individuals to conduct their own research. His publications are available on academic databases like Google Scholar. Additional resources can be found on his Boston College faculty page and through organizations like the Foundation for Metabolic Cancer Therapies.
