The Role of Keto in My Metabolic Cancer Therapy
For me, the ketogenic diet is a core component of my metabolic therapy — a strategy aimed at supporting mitochondrial function while reducing the availability of fuels that abnormal cells depend on. My focus is to maintain deep nutritional ketosis, where the body primarily uses fat-derived ketones rather than glucose for energy.
This approach is influenced in part by the work of Dr. Thomas Seyfried and others who explore the metabolic theory of cancer. Seyfried’s position is that many cancer cells rely heavily on fermentation of glucose and glutamine and cannot effectively utilize ketone bodies for energy, whereas healthy cells remain metabolically flexible and can function well in a ketogenic state.
I follow an 18-hour intermittent fast with a 6-hour eating window — typically from 9 AM to 2 PM — and maintain an approximate macronutrient ratio of 80% fat / 15% protein / 5% carbohydrate. This two-meal structure supports steady energy, low insulin signaling, and sustained nutritional ketosis throughout the day and night.

Key Dietary Principles
- Macronutrients: ~80% fat / 15% protein / 5% carbohydrate
- Fats: MCT oil, olive oil, GHEE, butter, macadamia nuts, avocado, brie
- Protein: eggs, limited dairy, steak, pork, poultry or fish
- Carbs: cruciferous, low-glycemic vegetables
- Fiber: daily intake from supplements and whole foods for gut health
Monitoring & Feedback
I track blood ketones and glucose to confirm my level of nutritional ketosis and make small adjustments as needed.
- Timing: I take readings before the first meal (typically 2–3 hours after waking) for consistency.
- GKI: I calculate the Glucose–Ketone Index (GKI) from those readings.
- Biomarkers: I periodically check selected metabolic and cancer biomarkers for long-term tracking.
- Subjective measures: energy, focus, mood, sleep, and recovery.
Target: maintain deep nutritional ketosis (GKI < 1.0) while preserving muscle and steady energy.
