The Ketogenic Diet's Role in Cancer Prevention and Treatment | Dr. Dominic D’Agostino

Ketogenic Diet and Mitochondrial Health

• 💡 The root of many diseases, including cancer, is dysfunction in the mitochondria.
• 🌱 A ketogenic diet can support mitochondrial health and function by providing an alternative fuel source.

Ketogenic Diet for Cancer Prevention

• 📉 By suppressing the hormone insulin and reducing blood glucose levels, the ketogenic diet limits glucose as a fuel source, promoting metabolic flexibility.
• ⚠️ Spikes in glucose can trigger pathways like IGF-1 and mTOR, which are associated with cancer growth; a ketogenic diet helps to reduce these spikes.
• 🚀 The diet, characterized by high fat, moderate protein, and fibrous carbs, creates an environment that may make cancer initiation and growth less likely.

Ketones as Fuel and Therapeutic Agents

• 🧠 Ketones, produced by the liver, serve as an energetic fuel source that can increase ATP production per unit of oxygen and produce fewer reactive oxygen species.
• ✨ Ketones also have epigenetic effects, acting as histone deacetylase inhibitors and interacting with histones, which can favor cancer suppression.
• 🎯 A "prescription ketogenic diet" aims for a glucose ketone index (GKI) between 1 and 3, which has demonstrated anti-seizure and neuroprotective effects, and significant tumor-suppressive potential.

Metabolic Therapy and Cancer Treatment

• 📈 Epidemiological data links hyperglycemia and hyperinsulinemia to a significantly higher incidence of cancer and systemic inflammation.
• ⚠️ Aggressive, metastatic tumors are highly glycolytic and rely on high glucose and insulin; targeting these fuels is crucial.
• 🔬 While some indolent cancers may use fatty acids or ketones for biosynthesis, aggressive tumors often have dysfunctional mitochondria and default to fermentable fuels like glucose and glutamine.

Practical Application and Research

• ✅ Improving cardiometabolic health through diet, stress reduction, and exercise is vital for cancer patients, especially to combat muscle wasting and cachexia.
• 🤝 Collaboration with open-minded oncologists and trained diet consultants is essential for implementing metabolic-based therapies.
• 📊 Monitoring glucose and ketone levels to achieve a therapeutic GKI of 1-3 is recommended, with a focus on whole foods and reducing processed carbohydrates.
• 🔬 While research is challenging, numerous clinical trials are exploring the ketogenic diet's efficacy in cancer treatment, often in conjunction with standard therapies.
