    Metabolism Over Dogma: Why We Both Moved Beyond Low Carb

    In this episode of Metabolic Mindset, I’m joined by Zane Griggs (@zanegriggsfitness), a long-time personal trainer and host of the Healthy AF Podcast. Zane and I met years ago when we were both deep in the low carb world. Since then, we’ve independently shifted toward a more pro-metabolic, physiology-first approach to nutrition and training. This conversation is about what actually works for our clients. We break down why restrictive frameworks like keto or low carb can initially “work,” the psychological pull of diet camps, and what happens when identity becomes tied to a way of eating. More importantly, we talk about what changed our minds—and the client results that forced us to rethink everything. We also dive into:  Why under-fueling and overtraining stalls fat loss  How higher carbohydrate, lower fat approaches can improve insulin sensitivity  Real client transformations (including improved A1C on higher carb intake)  Pre- and post-workout nutrition for performance and recovery  Common mistakes people make when trying to “optimize” their metabolism If you’ve ever felt stuck between conflicting nutrition philosophies, this episode will help you step back, think critically, and start trusting physiology over dogma.

    The Randle Cycle: A Physiology-Based Explanation of Fuel Competition and Energy Efficiency

    Episode 5 – The Randle Cycle: A Physiology-Based Explanation of Fuel Competition and Energy Efficiency Why do so many people feel better when they reintroduce carbohydrates — yet can’t explain why? In this episode of Metabolic Mindset, I break down the Randle Cycle, a core concept in metabolic physiology that explains how fat, protein, and carbohydrates compete for oxidation at the cellular level. You’ll learn why high fat intake can block glucose use, why excess protein without carbohydrates can leave you exhausted, and why carbohydrates are essential for efficient energy production. We’ll walk through the biochemistry of glucose and fatty acid oxidation, the role of pyruvate dehydrogenase (PDH), and how chronic low-carb, high-fat, or high-protein diets can push the body into a stress-adapted, inefficient metabolic state. I also explain how inadequate carbohydrate intake impacts thyroid function, cortisol, blood sugar stability, exercise performance, and overall energy availability. This episode is not about eliminating macronutrients — it’s about restoring fuel hierarchy, metabolic efficiency, and flexibility. If you’ve ever felt tired, cold, flat in workouts, or “carb intolerant,” this episode explains what’s actually happening physiologically — and why eating carbohydrates often fixes it.
