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 20: Updates on Genetics, Peptides, and Changes in Nutrition Polices

    In this episode, I’m sharing some real-life updates and what I’ve been seeing lately with genetics, toxins, and how our environment is quietly shaping our health (and our kids’ health 👀). I break down genetic expression in a way that actually makes sense—and why your genes aren’t your destiny, but your inputs matter. We talk peptides: what I’m seeing with growth hormone support, healing peptides, and why personalized protocols beat one-size-fits-all every time. I dive into school nutrition—how we went from real food to ultra-processed cafeteria meals, and why the return of things like whole milk is a big deal. I unpack the growing push to remove seed oils and artificial junk from kids’ food, and why this matters for gut health, behavior, hormones, and long-term metabolic health.

    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.

    Episode 18: Which exercise is right for you?

    Not all workouts are created equal — and the one that makes your friend feel amazing might leave you inflamed, exhausted, or burned out. In this episode, we break down the most popular workout styles and decode what’s actually happening inside your body when you do them. From heavy lifting to walking, running, HIIT, yoga, CrossFit, and more — we explore the science, the benefits, and the downsides of each so you can make smarter choices for your body. We talk genetics, hormones, inflammation, recovery, and why your “perfect” workout might look very different from someone else’s. This episode is all about learning how to move in a way that supports your health, your goals, and the body God uniquely designed for you. If you’re starting a new routine — or rethinking the one you’re already doing — this episode will help you train with clarity, confidence, and purpose.

    Episode 17: Depression: The Story We’ve Been Told Might Be Wrong

    What if depression isn’t what we’ve been told it is? In this episode, we unpack one of the biggest bombshells in modern mental health — the idea that depression may not be a simple chemical imbalance in the brain at all. Inspired by A Mind of Your Own by Dr. Kelly Brogan, we take a deep dive into the science that challenges the conventional narrative and asks us to look at depression as a whole-body experience, not just a brain disorder. We talk about how inflammation, hormones, gut health, nutrient deficiencies, thyroid function, trauma, stress, and lifestyle can all play powerful roles in mood — and why treating symptoms without addressing root causes may leave people feeling stuck. This episode isn’t about blaming, shaming, or dismissing anyone’s experience. It’s about opening the door to a much bigger conversation — one that offers understanding, agency, and hope. If you’ve ever felt like the standard explanation didn’t fully make sense… this episode might completely change the way you think about depression.

    Episode 16: Healing by Light: The Science of Red Light Therapy

    What if light — literal light — could help your body heal faster, move better, think clearer, and recover stronger? In this episode, we’re diving into red light therapy 🔴 — what it is, why it works, and why it’s becoming one of the most talked-about tools in recovery, wellness, and longevity. This isn’t woo-woo… it’s cellular science. We break down:  • What red and near-infrared light actually do inside your cells  • How light impacts mitochondria (your energy factories)  • Why red light supports muscle recovery, joint health, skin, and inflammation  • How it can help with hormones, sleep, and nervous system regulation  • Why humans were designed to interact with light  • How to use red light safely and effectively (without overdoing it) We’ll also talk about how modern life pulled us away from natural light — and how red light therapy may help restore something we’re missing. Ancient wisdom meets modern science in this episode — and once you understand how light communicates with your body, you’ll never look at recovery the same way again. Turn on the light… and let’s get into it ✨

    Episode 15: Turning Up the Heat: The Science-Backed Benefits of Saunas

    What if sitting still… sweating… and being slightly uncomfortable was actually one of the healthiest things you could do? In this episode, we’re turning up the heat 🔥 and breaking down why saunas have been used for centuries — and why modern science is finally catching up. From heat-shock proteins and detox pathways to cardiovascular health, muscle recovery, stress reduction, hormone support, and even longevity, saunas do way more than just make you sweat. We’ll talk:  • What’s actually happening inside your body when you sauna  • Why heat is a powerful (and intentional) stressor  • How saunas support heart health, metabolism, and recovery  • Why sweating isn’t the enemy — it’s the point  • Who should (and shouldn’t) use a sauna  • How to use sauna safely and effectively This episode is part science, part ancient wisdom, part “why does this feel so hard but so good?” — and it might just change how you think about heat forever. Grab some water, get cozy (or hot 😅), and let’s sweat with a purpose.

    Episode 14: Understanding Fevers: Why Your Body Raises Its Temperature

    Hot, Not Broken: Why Fevers Might Actually Be a Good Thing If your first instinct when a fever hits is to panic, grab meds, and try to shut it down immediately… this episode is for you. Because plot twist: a fever isn’t your body malfunctioning — it’s your immune system clocking in and doing its job. In this episode, we’re turning up the heat (literally) and breaking down what a fever actually is, why your body raises its temperature on purpose, and how that heat helps fight infections, activate immune cells, and create a stronger immune memory. We’ll nerd out on the science behind fevers, talk about what’s happening at a cellular level, and explain why “normal temperature” isn’t the whole story. We’ll also cover when fevers are helpful, when they need extra attention, and why constantly suppressing them might not always be the best move. Add in genetics, inflammation, immune resilience, and a little common sense — and suddenly fevers make a lot more sense. If you’ve ever wondered whether your body might be smarter than we give it credit for… this episode will definitely make you think twice before reaching for the thermometer in fear.
