How Fasting Affects Cancer Cells

Описание: Daily intermittent fasting is gaining attention in cancer research — not as a treatment, but as a lifestyle strategy that may support a healthier metabolism, lower insulin and IGF-1 levels, reduce inflammation, and activate autophagy. In this video, Keith Bishop, Integrative Cancer Educator and founder of Prevail Over Cancer, breaks down the science in a clear, patient-friendly way.
You’ll learn:
• How intermittent fasting affects glucose, insulin, and IGF-1
• Why cancer cells struggle with metabolic stress
• How fasting activates autophagy and cellular repair
• What types of cancer appear sensitive to metabolic changes
• Whether fasting may help during treatment (and when it should NOT be used)
• How to start fasting safely with 12–16 hour windows
• How to use a bioimpedance body composition scale once a week to track muscle, fat, water, and bone trends
• How fasting fits into a terrain-based, whole body approach to cancer support
