Metabolic Mindset

In Part 2 of the cholesterol series, we're taking a deeper look at why cholesterol labs are often misunderstood and why context matters when evaluating cardiovascular risk. We'll break down markers like LDL, HDL, triglycerides, ApoB, and ApoA1, discuss the role of inflammation and metabolic health, and explore why two people with similar cholesterol numbers can have very different risk profiles. We'll also dive into statins—how they work, why they're so heavily debated, and the situations whe...

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 ...

In this episode of Metabolic Mindset, Registered Dietitian Shara Perry breaks down why more exercise isn’t always the answer for fat loss. Chronic high-intensity training, under-fueling, and elevated cortisol can actually stall fat loss by breaking down muscle, lowering metabolic rate, and signaling the body to hold onto energy. Shara explains the physiology behind Zone 1 and Zone 2 cardio, how they support mitochondrial health, fat oxidation, and cortisol regulation, and why lower-stress tra...

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...

In this episode, we break down why fat loss can stall even when calories are controlled and workouts are consistent. You’ll learn how cortisol, thyroid signaling, fuel availability, and recovery determine whether your body burns fat or holds onto it—and why eating less is often not the answer.

What is a pro-metabolic diet, really? In this episode, Shara breaks down the physiology behind metabolism, why so many mainstream nutrition messages backfire (like “eat less, move more” and “carbs slow your metabolism”), and what it actually means to support the thyroid and mitochondria. You’ll learn the core principles of a pro-metabolic approach, why carbs and minerals matter, and how to start fueling your body without extremes.
