Cancer’s Sweet Tooth: Sugar, Metabolism & the Warburg Effect

What if one of cancer’s greatest vulnerabilities is hiding in plain sight?

On this episode of Sugar Crush: The Rest of the Story, Dr. Rick Jacoby tackles one of the biggest subjects of the series: cancer and metabolism—and explores the long history behind scientists’ understanding of how many cancer cells use glucose.

The journey begins nearly a century ago with Nobel Prize-winning scientist Otto Warburg, whose research revealed that cancer cells frequently rely heavily on glucose metabolism even when oxygen is available—a phenomenon that became known as the Warburg effect. Dr. Rick then brings the conversation forward to the work of Thomas Seyfried and the modern debate over viewing cancer, at least in part, through a metabolic lens. 

But Dr. Rick takes the discussion in his own direction.

Drawing on decades of experience with diabetic neuropathy, nerve decompression and microsurgery, he connects the Double Crush Theory to his own broader Global Compression Theory and introduces the concept of the “estuary”—areas where he believes impaired circulation, inflammation, metabolic dysfunction and tissue damage may converge.

Using the Mississippi River’s dead zone as his metaphor, Dr. Rick asks whether similar biological “dead zones” could develop throughout the body—and whether those environments might contribute to disease.
