Why You're Not Building Muscle After 40: Protein Pulses, Leucine Threshold & MPS Explained

Are you working out, eating "clean," and even adding protein or amino acids… but still not seeing changes in your muscle, metabolism, or body composition? You're not alone—and you're not doing it wrong. 👉 The rules have changed. In this episode of The Coach Debbie Potts Show, we dive deep into the science of muscle protein synthesis (MPS) and why midlife women need a different strategy to build and maintain lean muscle. This is Part 1 of a powerful series where we break down: What muscle protein synthesis (MPS) actually is Why anabolic resistance makes it harder to build muscle after 40 The critical role of leucine and mTOR signaling Why 30–40g of protein may not be enough for optimal results The concept of protein pulsing and why timing matters How amino acids like BodyHealth PerfectAmino support—but don't fully replace—protein intake The difference between "strong signals" vs "support signals" when it comes to muscle building You'll also learn why: 👉 Muscle building is NOT constant—it's pulsed 👉 You need 3–4 full MPS activations per day 👉 And why many women are unknowingly under-signaling, not under-eating This episode lays the foundation for understanding how to fuel your body properly so you can: Build lean muscle Improve metabolism Support hormone balance Age stronger, not slower 🔑 KEY TAKEAWAY It's not about eating more… 👉 It's about sending the right signal, at the right time, enough times per day. 🎯 READY TO PERSONALIZE YOUR PLAN?

Understanding the Signals That Control Your Metabolism If you feel like your body isn't responding the way it used to… you're not alone. You may be eating well, training consistently, and doing everything you've been told should work—yet your energy is off, recovery is slower, and body composition is changing. This series explains why. In this multi-part deep dive, Debbie Potts—Functional Diagnostic Nutrition Practitioner and Metabolic Health Coach—walks you through what is really happening beneath the surface. This is not a conversation about eating less or exercising more. It is about understanding how your body communicates. Because your metabolism is not just about calories or hormones. It is controlled by a network of signals between your brain, gut, muscles, mitochondria, and nervous system. When those signals become disrupted, the body adapts in ways that can feel frustrating and confusing. Fatigue, weight gain, hormone imbalances, and poor recovery are not random. They are clues. Debbie refers to this as "Metabolic Chaos"—a state where the body is no longer communicating efficiently. Throughout this series, you will learn how to recognize the patterns behind metabolic dysfunction and how to begin restoring balance by improving communication within the body. Topics covered in this series include: Why metabolism changes in midlife and what is actually driving those changes How stress, sleep, and the nervous system influence fat metabolism and energy The connection between gut health, inflammation, and hormone balance Why cell membrane health and receptor function are critical for results The role of muscle in long-term metabolic health and aging How mitochondrial function influences energy, endurance, and recovery This series also introduces a more personalized, data-driven approach to health. Rather than guessing, Debbie explains how functional testing can reveal where your body is struggling, including: Functional blood chemistry DUTCH hormone testing GI-MAP stool analysis 3x4 genetic insights PNOĒ metabolic testing Mitochondrial and oxidative stress markers You will also be introduced to the key signals that regulate metabolism, including blood sugar control, cellular health, energy production, gut function, inflammation, detoxification, and recovery. When these systems are aligned, the body works more efficiently. When they are not, progress can feel stalled—even when effort is high. This series is designed to help you connect the dots, understand your body at a deeper level, and begin creating a strategy that works with your physiology instead of against it. If you are ready to stop guessing and start understanding your unique physiology, you can learn more and schedule a FutureYou Blueprint Discovery Call at: www.debbiepotts.net Your body is not working against you. It is responding to the signals it receives. When you understand those signals, you can begin to change your trajectory and build your FutureYou from the inside out.

What if the way you've been training is actually working against your metabolism… especially in midlife? In this episode of The Coach Debbie Potts Show, I sit down with endurance pioneer and heart rate training expert Sally Edwards to break down how to truly train smarter—not harder—as you age. This conversation is a deep dive into what your body actually needs for performance, fat loss, and longevity… and why more intensity, more stress, and more "pushing through" may be the exact reason you feel stuck. We unpack the science and real-life application of heart rate training, metabolic efficiency, and how to build a body that performs better with less burnout. In This Episode, We Discuss: • What heart rate training really means—and why most people get it wrong • How to train for fat burning vs. sugar burning • Why Zone 2 is essential for mitochondrial health and longevity • The connection between endurance training, stress, and metabolic dysfunction • How midlife changes your response to training (and what to do about it) • Why more intensity is NOT the answer for fat loss or performance • How to build true metabolic flexibility Why This Matters for YOU: If you're feeling stuck… tired… plateaued… or like your body isn't responding the way it used to… This episode will help you understand why—and what to do instead. Because it's not about doing more. 👉 It's about training in alignment with your physiology. Ready to Take This Deeper?

Are you great at burning fat—but struggling with recovery, muscle, energy, or stubborn body composition? In this Part 1 episode, Coach Debbie Potts takes you down a deep-dive rabbit hole into AMPK dominance, the "burn mode" many high performers and endurance athletes unknowingly live in. You'll learn how chronic stress, under-fueling, fasting, and excessive endurance training can shift your body into energy conservation instead of rebuilding—and why this becomes even more important in midlife. Debbie breaks down the difference between being a fat burner vs. metabolically flexible, and how PNOĒ metabolism testing reveals key clues at rest (RMR) and during exercise (AMR), including: • Low resting metabolic rate (RMR) and what it really means • Fat-burning dominance vs true metabolic flexibility • Poor high-intensity capacity and "flat" performance • Limited carbohydrate access when you need it most • Signs of chronic AMPK activation and reduced mTOR signaling This episode will help you understand why your body may feel stuck—even when you're doing everything "right"—and why the solution isn't more discipline, but better metabolic signaling and strategy. This is where you stop guessing… and start connecting the clues. 👉 Ready to understand your metabolism and create your personalized FutureYou Blueprint?

What if your metabolism isn't broken—but your body's communication system is? In this multi-part deep dive, Debbie Potts—Functional Diagnostic Nutrition Practitioner, Metabolic Health Coach, and host of The Coach Debbie Potts Show—explores why so many high-performing individuals feel stuck despite doing everything "right." This series goes beyond calories, workouts, and surface-level hormone advice. Instead, it uncovers the deeper physiology of metabolic health by focusing on how the body functions as an integrated system of signals. Your metabolism is not just about food or exercise. It is about communication between your cells, hormones, gut, brain, and nervous system. When that communication becomes disrupted, the body adapts in ways that feel like dysfunction—fatigue, weight gain, hormone imbalance, and poor recovery. Debbie calls this state "Metabolic Chaos." In this series, you will learn how to shift from metabolic chaos to metabolic harmony by understanding and restoring the key signals that drive energy, fat metabolism, and resilience as you age. In this series, you will learn: What metabolic dysfunction really is—and why it often shows up in midlife How hormones, mitochondria, muscle, and the nervous system are interconnected Why cell membrane health and receptor sensitivity determine whether your body responds to signals The role of gut health in fat metabolism, inflammation, and energy production How chronic stress, overtraining, and under-recovery disrupt metabolic signaling Why traditional approaches stop working after 40 This series also introduces Debbie's "test, not guess" approach to health optimization. Rather than relying on generic protocols, she uses functional lab testing and metabolic analysis to identify where your system is breaking down. You will learn how tools such as functional blood chemistry, DUTCH hormone testing, GI-MAP stool analysis, 3x4 genetics, PNOĒ metabolic testing, and mitochondrial markers can provide insight into your body's internal communication system. At the core of this series are the nine key signals that restore metabolic harmony, including blood sugar stability, cell membrane health, mitochondrial function, hormone signaling, gut microbiome communication, oxygen utilization, inflammation control, detoxification pathways, and recovery. After age 40, the body becomes more sensitive to disruptions in these systems. When signals are out of alignment, fat loss becomes more difficult, muscle is harder to maintain, energy becomes inconsistent, and hormones feel imbalanced. The goal is not to fight your body, but to understand how it works. Debbie's core message is simple: you do not fix metabolism by working harder—you fix it by improving how your body communicates. If you are listening and recognizing that something feels off despite your best efforts, the next step is not more guessing. It is gaining clarity.

What if your endurance journey didn't start in your teens… but in your late 40s? In this episode of The Coach Debbie Potts Show, I sit down with Hilary Topper, who began endurance training at 48, started training for triathlons at 53, and built her "why" around one simple mission: to become the best version of herself. Hilary shares the real behind-the-scenes of starting "later," learning new skills from scratch, and building the discipline to show up—especially when it means a 4:00 AM alarm and doing hard things before most people are awake. We also celebrate Hilary's newest project: her recently launched fourth book, Unlocking the Triathlon: The Beginner's Guide to Competing in a Triathlon—Anyone Can Tri, published by Meyer & Meyer Sport. In this episode, you'll hear: Why Hilary started endurance training later in life—and what changed everything for her Whether she was an athlete earlier in life (and how that shaped her comeback story) How hard it was to learn how to swim (and what helped her finally "get it") How 4:00 AM became a habit—without relying on motivation What it really takes to build consistency, confidence, and identity as a triathlete—at any age Connect with Hilary Instagram: @hilarytopper Website: ATriathletesDiary.com

If you're over 40 and doing "everything right" — eating clean, lifting weights, prioritizing sleep — but your metabolism feels slower, hunger feels stronger, and fat loss feels harder… This episode explains why. In this deep-dive rabbit hole, Coach Debbie Potts uncovers the powerful (and often overlooked) connection between bile flow, mitochondrial efficiency, GLP-1 signaling, hormones, and midlife metabolism. Bile acids are not just digestive fluids. They are metabolic signaling molecules that regulate: • GLP-1 and PYY (satiety hormones) • Insulin sensitivity • Fat oxidation • Thyroid receptor expression • Estrogen clearance (the estrobolome) • Microbiome balance • Inflammatory tone • Toxin elimination You'll learn how midlife hormonal shifts — including declining estrogen and testosterone — affect mitochondrial ATP production, bile synthesis, and receptor signaling. When bile signaling weakens, GLP-1 drops, hunger rises, insulin resistance increases, fat oxidation declines, inflammation builds, and metabolism adapts downward. This isn't a willpower problem. It's a signaling problem. High performers often feel this shift first because chronic stress suppresses digestion, weakens vagal tone, reduces stomach acid, impairs gallbladder contraction, and disrupts bile release. In this episode, Debbie connects the dots and explains the midlife cascade: Hormone shift → Mitochondrial decline → Bile signaling weakens → GLP-1 drops → Insulin resistance rises → Fat oxidation slows → Inflammation increases → Thyroid sensitivity declines → Metabolic rate adapts downward. You'll also learn why GLP-1 medications are exploding in popularity — and why restoring upstream physiology may be the more sustainable path. Instead of pushing harder, we sequence smarter. When flow restores, metabolism follows. 👉 Learn more at www.debbiepotts.net Aging is inevitable. Struggling is optional. Educational only.
