Insulin, Mitochondria, and GLP-1s: What Really Drives Fat Burning and “Biological Aging”
Kim and Ray demystify metabolic health by linking fuel choice, mitochondria, and the latest GLP‑1 headlines. Learn why stored fat isn’t always burned, how the Randle (glucose–fatty acid) cycle and insulin act as the traffic cop for fuels, and why carbohydrate restriction can shift the body into greater fat oxidation. We dig into what insulin resistance really means—a mismatch where fat keeps spilling into circulation while muscles can’t switch to burn it—plus why mitochondria often look overwhelmed rather than ‘‘broken.’p> Practical takeaways: exercise builds mitochondrial capacity, lowering chronic fuel overload helps more than supplements, and GLP‑1 drugs like semaglutide show intriguing signals on biological aging (possibly via inflammation and visceral fat loss) but aren’t a universal anti‑aging cure. Subscribe to I Am Healthy Money™ with Kim and Ray for evidence‑forward deep dives into health, longevity, and financial freedom—one research‑backed episode at a time.
