Periodic Prolonged Fasting After Pancreatic Cancer Diagnosis
Berg frames this as the single most important action to take after a diagnosis. He argues that cancer not only requires fuel but also needs a membrane infrastructure; fasting deprives it of resources. He emphasizes that cancer cells make building membranes a higher priority than just obtaining energy, so cutting off material supply lines through fasting can slow or reverse growth. He describes periodic prolonged fasting as safe and effective, a counterpoint to conventional standard-of-care which often does not prioritize metabolic interventions.
During fasting, glucose and insulin levels drop, which can starve cancer cells that rely on glucose. Additionally, Berg explains that the cancer aggressively scavenges lipids and proteins for membrane synthesis; prolonged fasting deprives it of these resources, hindering tumor growth and potentially forcing the cancer into a less aggressive state. The lack of oxygen inside the tumor may further fuel the spread, so metabolic interventions are critical.
The most important thing that a person should do if they're diagnosed with this type of cancer is immediately start doing prolong fasting.
