In this episode of the Well Beyond 40 podcast, host JJ Virgin interviews metabolic‑health expert Zane Griggs to dissect why extreme biohacking—excessive low‑carb/keto diets, prolonged fasting, high‑intensity training, and reliance on GLP‑1 drugs—often backfires for high‑performers over 40. They trace the physiological cascade that starts with chronic elevation of the stress hormone glucagon, progresses through adrenaline and cortisol, and culminates in impaired mitochondrial ATP production, insulin resistance, thyroid dysregulation, and declining testosterone. Both guests argue that ultra‑processed foods, poly‑unsaturated seed oils, and chronic under‑fueling are the true culprits, not carbs themselves. Practical recommendations include: shifting to whole‑food, single‑ingredient meals; incorporating moderate carbohydrate timing around workouts; prioritising recovery, mobility, and sleep; using targeted lab markers (fasting insulin, glucagon, reverse T3, free testosterone) to catch early dysfunction; and fostering supportive relationship dynamics so partners can co‑manage health goals. The conversation also touches on the cultural swings in diet fads, the importance of gut health (butyrate), and the need for data‑driven coaching rather than dogmatic biohacking.
