Fit Nerd is where faith, fitness, and science collide. We geek out on genetics, health, and training — all while keeping Christ at the center. From nutrition and hormones to joyful movement and real-life faith, you’ll discover how to work with the body God designed so you can feel strong, energized, and fearfully fit. I like to explore the current trends- food, exercise, and lifestyle- and discuss who that trend will benefit and why.

    Episode 26: GLP-1s Explained: Pros, Cons, and My Real Take On Them.

    GLP-1s are everywhere right now — Ozempic, Tirzepatide, Retatrutide… and if you feel like everyone and their neighbor is on one, you’re not wrong. But here’s the real question no one is asking loud enough: 👉 Are these making us healthier… or just skinnier? In this episode, I’m diving DEEP into the conversation I feel like I’m having every single day — with clients, friends, family, and honestly… strangers at this point. And listen, I’m not here to bash GLP-1s. I actually think they can be incredible tools. But what I’m seeing right now? A whole lot of people using them the wrong way… and paying the price. We’re breaking down: What GLP-1s actually do (beyond just “you’re not hungry”)The real differences between Ozempic, Tirzepatide, and RetatrutideWhy some people are THRIVING on them… and others are crashingThe side effects no one is talking about (muscle loss, bone density, hormone disruption 👀)Why “just eating less” is NOT the flex people think it isAnd how to use these as a tool to build your body — not break itWe’re also getting into: The two (honestly THREE) types of people using GLP-1s right nowWhy your approach matters more than the peptide itselfThe biggest dosing mistakes I keep seeingHow microdosing can completely change your experienceAnd what to stack with GLP-1s if you actually care about your muscle, metabolism, and long-term healthBecause here’s the truth: You can lose 20 pounds… …and still end up in a worse place metabolically. Or — you can use this season to rebuild your body the way it was designed to function. Around here, we’re not chasing skinny. We’re building strong, fueled, thriving bodies that last. So if you’ve been: Curious about GLP-1sConfused by all the information out thereOr wondering if they’re right for youThis episode is going to give you clarity, conviction, and a whole new perspective. Because the question isn’t: “Should I take a GLP-1?” It’s: 🔥 “Am I willing to do this the right way?” Let’s get into it.

    Episode 23: Protein Powders: What to look for, what they are made of, and how they work.

    Protein powder isn’t just a convenience food — it’s a metabolic signal. In this episode, we go beyond “20 grams per scoop” and talk about what protein actually does inside the body. Because when you ingest protein, you’re not just building muscle — you’re activating pathways. We break down: How protein is digested into amino acids and absorbedWhy leucine is the key trigger for mTOR and muscle protein synthesisThe difference between complete and incomplete proteinsPDCAAS and bioavailability (why 20 grams isn’t always 20 usable grams)Whey vs. plant protein from a digestion, absorption, and anabolic standpointWhat amino acid spiking is — and how companies game labelsThe role of essential amino acids in preserving lean massWe also unpack Gary Brecka’s Perfect Amino — what free-form essential amino acids are, how they’re absorbed differently from intact protein, and whether they truly improve nitrogen balance and utilization compared to whole food protein. And yes, we talk about the darker side of the industry: Heavy metalsArtificial sweeteners and insulin responseGums and gut irritation“Natural flavors”This is a deep dive into the physiology of protein — how it influences muscle, metabolism, blood sugar regulation, satiety hormones, and even aging pathways. If you care about performance, body composition, longevity, or feeding your family well, this episode will change how you look at that scoop forever. Because protein isn’t just macros. It’s messaging.

    Episode 22: Overfed & Undernourished: What’s Really Happening in Our Kid's Bodies

    For the first time in history, more children worldwide are living with obesity than are underweight. Let that sink in. In this episode, I’m unpacking the presentation I gave on nutrition in our schools — and what I discovered is both eye-opening and deeply concerning. We are raising the most overfed yet undernourished generation in history. This isn’t about shaming parents.  It’s not about blaming schools.  It’s about biology. I break down what actually happens inside a child’s body when they eat — how protein builds brains and stabilizes behavior, how carb-heavy ultra-processed diets spike blood sugar and fuel mood swings, why healthy fats are critical for hormones and nervous system development, and how seed oils and food dyes may be quietly contributing to inflammation, focus issues, and long-term metabolic damage. We talk about: Why kids need more nutrients than adults (not less)The gut microbiome and why early nutrition programs lifelong healthWhat teachers and coaches are really seeing in the classroom and on the fieldHow school guidelines prioritize cost and compliance over cognitionThe long-term risks we are setting up if we don’t course-correctBecause when we feed kids poorly and expect them to focus, regulate emotions, and perform — we are asking their biology to do something it simply cannot do. This episode is science-heavy, practical, and faith-rooted.  Our kids are fearfully and wonderfully made — and their growing bodies deserve fuel that reflects that. If you’re a parent, educator, coach, or just someone who cares about the next generation, this conversation matters. Small changes. Big impact.  Let’s do better for our kids.

    Episode 19: What Nootropics, Pre-Workout, and Nicotine Really Do to Your Brain

    This one is for Tony J! We’re tired…   So naturally, we’re reaching for pre-workout, energy drinks, “focus” supplements, and yes — even nicotine — just to get through workouts, workdays, and life. But what if more energy isn’t the answer? In this episode, we dive deep into the world of nootropics, what they actually are (and what they are not), and how they differ from traditional pre-workout supplements that spike adrenaline, cortisol, and caffeine tolerance. We break down the science of neurotransmitters, brain energy, stress hormones, and nervous system regulation — in a way that actually makes sense — so you can understand whether you’re building focus and performance… or just borrowing it from tomorrow. We also tackle the spicy topic of nicotine — why it’s suddenly trending as a “brain hack,” what the research really says about its effects on focus and cognition, and why short-term mental sharpness can come with long-term neurological trade-offs. This isn’t fear-based or hype-driven — it’s a clear, balanced look at what’s happening inside your brain and body. If you’ve ever wondered: Why pre-workout feels amazing… until it doesn’tWhether nootropics are actually safer or just marketingHow stimulation impacts hormones, sleep, recovery, and motivationOr how to support your brain without frying your nervous systemThis episode is for you. As always, we bring it back to biology, stewardship of the body, and honoring how we were designed to function — not forcing performance at the expense of long-term health. Because real strength isn’t being wired…  It’s being regulated.
