Travis Christofferson is the science writer behind Tripping Over the Truth, and the case he makes is one of the most quietly radical ideas in modern medicine: that we may already have the tools to treat most cancers, most of the time, and that the reason we don't use them has more to do with entrenched paradigms than with the limits of science. In this episode, Travis walks Aubrey through the metabolic theory of cancer, the century-old insight (first glimpsed by Nobel laureate Otto Warburg in the 1920s) that cancer behaves less like a genetic accident and more like a disease of broken cellular energy. They get into why cancer cells ferment sugar instead of breathing oxygen, why that single difference flips the entire treatment model on its head, and why a PET scan, which lights up tumors using radiolabeled glucose, is staring at the answer every single day. Travis explains how starving cancer cells with fasting and the ketogenic diet makes healthy cells more robust while putting malignant ones under lethal stress, and how repurposed generic drugs (ivermectin, fenbendazole, metformin) may be quietly doing the same thing through mechanisms almost nobody is studying. The conversation widens into something bigger than biology: why a system built on FDA monotherapy trials and patent incentives ignores cheap combination therapies that could change everything, how fear short-circuits our ability to think clearly when a diagnosis lands, and why the most hopeful reframe of all is to stop waging war on our own sick cells and start trying to heal them. Aubrey shares the personal loss that drew him to this work, and the strange peace that came from realizing there might actually be a path. We discuss: the metabolic theory of cancer and how it differs from the genetic model, Otto Warburg and the golden age of unencumbered science, why cancer cells ferment glucose (the Warburg effect), the mitochondria as little sick patients rather than enemies to be killed, how fasting and ketosis starve tumors while strengthening healthy cells, the role of insulin and IGF-1 as growth signals, hexokinase two and how repurposed drugs may block it, the ivermectin and mebendazole observational cancer data, why generic drugs never get the trials they deserve, the "plagues of prosperity" and the modern toxic load, how fear and tribalism distort medical decision-making, and Travis's prophylactic protocol (quarterly keto plus hyperbaric oxygen) for staying ahead of disease.
