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.
