Ep336: Not Seeing Muscle? Your Cortisol Might Be the Problem with Katie Hardie

from Fit + Fueled Life Podcast

If you've been doing the work (lifting, eating well, staying consistent), but your body still isn't responding the way you expect, this episode is for you! I sat down with coach Katie Hardie to talk about something that doesn't get nearly enough attention in the body composition conversation: cortisol. Not in a vague, stress-is-bad, you need a “cortisol coach” way, but in a real, specific, this-might-be-exactly-what's-happening-in-your-body way. We get into how chronic stress, under-fueling, poor recovery, and a nervous system that never fully downregulates can quietly work against muscle growth, even when you're doing everything else right. We also talk about why doing more is often the worst thing you can do, how cortisol affects where your body stores fat, and what it actually looks like to support your body in a way that lets muscle develop over time.This one hit close to home for me. I think it will for a lot of you too. Here’s what you’ll learn: - The real reason you’re training hard but not seeing muscle or fat loss - How stress hormones put your body into breakdown mode instead of build mode - What “cortisol face” and stubborn belly fat might actually be telling you - Signs your body is under-fueled (even if you’re eating “healthy”) - The difference between productive training vs. chronic overtraining - Why dysregulated cortisol makes it harder to build and keep muscle - The subtle signs you’re not recovering properly - Should you take cortisol-lowering supplements (or is that missing the point)? - Why intermittent fasting may be making belly fat worse for some women - What your liver and digestion have to do with fat loss and hormone balance - Simple ways to reduce stress around meals and make nutrition more sustainable Subscribe: https://carrotsncake.substack.com Join Fit + Fueled: https://carrots-n-cake.mykajabi.com/fit+fueled Connect with Tina Haupert: https://carrotsncake.com/ Facebook: Carrots 'N' Cake https://www.facebook.com/carrotsncake Instagram: @carrotsncake https://www.instagram.com/carrotsncake YouTube: Tina Haupert https://www.youtube.com/user/carrotsncake About Tina Haupert: Tina Haupert is the owner of Carrots ‘N’ Cake as well as a Certified Nutrition Coach and Functional Diagnostic Nutrition Practitioner (FDN-P).

Whether the performance focus is athletic, professional, or personal, we determine the appropriate types of work, recovery, and diet to maximize energy. Through increased awareness of our body's signals that most of us have been conditioned to normalize or ignore, we learn the feedback our body offers us and pair it with objective biometrics. We also gain knowledge about our internal current state of gut functioning, stress and sex hormones, heart and kidney health, liver and thyroid function, and vitamin and mineral status through running functional labs. Combining my training in strength and conditioning, sport and performance psychology, nutrition, and personal cheffing, I personalize the curriculum throughout virtual coaching sessions in order to optimize energy and as a byproduct, body composition. I support clients along each one's unique journey so he or she can thrive with full potential.
