Ep. 14: Peptides Explained: What They Are and Why Everyone’s Talking About Them

Ep. 14: Peptides Explained: What They Are and Why Everyone’s Talking About Them

Everyone's talking about peptides. GLP-1s are everywhere, the "glow stack" is all over your feed, and somehow your soccer mom neighbor is microdosing tirzepatide. But most of what's circulating is either oversimplified or just wrong. I brought in Luis Villaseñor, Co-Founder of LMNT and someone deep in this space for over a decade, to have the real conversation: what peptides actually are, which ones work, and the part no one's saying out loud. I've been microdosing tirzepatide and had a lot of questions I couldn't find straight answers to. So I brought in Luis Villaseñor, co-founder of KetoGains and LMNT, someone who's been deeply involved in this space for over a decade, to have a real conversation. Not the TikTok version. The actual one. Peptides are not supplements, and they're not steroids. They're short chains of amino acids that signal your body to do things it's already designed to do — insulin is one, oxytocin is another. What's changed is access, cost, and the flood of information (and misinformation) that came in on the heels of the Ozempic wave. We got into how GLP-1s actually work for fat loss, including the part most people skip: without enough protein and strength training, up to half the weight lost on these compounds can be lean tissue. That has long-term metabolic consequences most people don't hear about until it's already happened. We also talked about the "glow stack" (BPC-157, GHK-CU, TB-500) for skin and systemic inflammation, sleep peptides like DSIP, what's coming in longevity research, and the honest answer on whether any peptide can actually build muscle right now (spoiler: no). And we spent real time on sourcing, because most people have no idea where these compounds are actually coming from, and that matters a lot more than the dose. Luis's bottom line, and mine too: peptides can be a powerful tool. But they work best on top of an already solid foundation, not instead of one. KEY TAKEAWAYS 1. Peptides are not supplements, and they're not steroids. They're short amino acid chains that act as messengers, signaling your body to do things it's already designed to do — just more efficiently. 2. GLP-1s reduce food noise and support fat loss, but without adequate protein and strength training, a significant portion of the weight lost can be lean muscle — which is metabolically devastating long-term. 3. The "glow stack" (BPC-157, GHK-CU, TB-500) isn't just for aesthetics — it reduces systemic inflammation, accelerates healing, and supports collagen production. It's one of the most broadly beneficial combinations for most people. 4. Sourcing matters enormously. The gray market is real, unregulated, and risky. Independent lab-testing databases (like Janoshink) exist for a reason. A reputable clinic with purity documentation is the safest starting point. 5. Peptides work best as a tool on top of a solid foundation — not as a replacement for one. If the habits aren't there, most peptides will either underperform or create dependency.

Ep. 13: The Trip You Keep Postponing Is Trying to Tell You Something — What Your Wanderlust Is Actually About

There is a trip on your list. Maybe it has been there for years. And every time you almost book it, something gets in the way — the kids, the calendar, the voice that says not yet. In this episode, Kathy sits down with storyteller, creative strategist, and global nomad Natasha Ibrahim — who has traveled to 56 countries and built a community of women living life on their own terms — to explore what that pull toward somewhere new is really about. Because wanderlust is not just restlessness, it is your body asking you a real question. And this summer, it deserves a real answer. Natasha has built a community called Girl Boss Abroad — a space for women who want to travel intentionally and take care of themselves while doing it. She weaves breathwork, sound baths, and self-care rituals from cultures all over the world into the way she lives and moves. In this conversation, Kathy and Natasha go deep into what summer travel actually does to a woman's body and nervous system, why so many high-achieving women show up somewhere beautiful and still can't fully arrive, and what it takes to finally give yourself permission to go. WHAT YOU WILL LEARN: — Why the trip you keep postponing may be one of the most important things you can say yes to this summer — What travel does to the nervous system and why unfamiliar environments accelerate self-awareness — The self-care rituals women around the world practice in summer that we in the West have almost entirely forgotten — How to know in your body when a decision is right — even when the timing feels impossible — What makes one trip transform you, and another simply exhaust you somewhere prettier ABOUT NATASHA IBRAHIM: Natasha Ibrahim is a storyteller, creative strategist, and digital nomad who has visited 56 countries and built a global community called Girl Boss Abroad. Her work lives at the intersection of travel, self-discovery, and wellness. She coaches women on remote work, financial independence, and the wellness habits that make an intentional life sustainable.

Ep. 12: Movement as Medicine: How Sanctum is Rebuilding Community through Collective Experience

Episode Summary What happens when a group of strangers comes together, moves in sync, and leaves feeling completely different? In this episode of Embodied, Kathy sits down with Luuk Melisse, founder of Sanctum, to explore the science and experience behind collective movement, emotional connection, and the future of fitness. Recorded at the Global Wellness Summit in Dubai, this conversation moves beyond traditional workouts and into something deeper. Together, Kathy and Luuk unpack how movement, music, environment, and storytelling can shift the nervous system, create belonging, and unlock emotional release. Luuk shares his journey from professional dancer to founder, shaped by early exposure to spirituality through his mother and a personal turning point after her passing at age 21. That experience led him to explore Kundalini yoga, meditation, Buddhism, vision quests, and Vipassana, ultimately inspiring him to create Sanctum. Sanctum was designed to bridge two worlds, the spiritual and the modern, blending high-intensity movement with breathwork, techno music, mantras, voice, and synchronized repetition. The result is a powerful shared experience that creates what he describes as “collective effervescence,” a feeling of connection, belonging, and emotional release. What began as small, almost underground sessions during lockdown in Amsterdam has grown into a global movement, expanding to London and Dubai. At its core, Sanctum is built on community and intentional design, using storytelling structured like a movie with a beginning, climax, and closing to guide participants through a full emotional journey. Luuk also shares how Sanctum is scaling through a hybrid training model inside the Sanctum Academy, and how the brand continues to push boundaries by hosting classes in unique environments like churches, art galleries, deserts, ruins, and even glaciers. They also discuss the future of the brand, including the upcoming launch of the Sanctum app, offering immersive digital sessions and guided movement experiences in nature, with expansion into the U.S. on the horizon. At the center of this conversation is a powerful truth: community isn’t the byproduct, it’s the mechanism for transformation.

Ep 11. NAD for Longevity: Methylene Blue, VO2 Max Testing, and Smarter Supplementation - Part 2

Alexander Audit | Chief Scientific Officer | NAD Clinic Alexander Audit is a former chemical engineer turned integrative clinician, trained in traditional Chinese medicine and nutritional medicine. As Chief Scientific Officer of NAD Clinic — a global leader in cellular health and performance medicine operating in more than 40 countries — he bridges hard science with real-world application. His work centers on NAD, the molecule at the heart of cellular energy, brain health, and longevity. Last week, Alexander Audit joined Kathy at the Global Wellness Summit in Dubai to break down the science of NAD — what it is, why levels begin declining as early as our 30s, and how that shows up as fatigue, brain fog, and accelerated aging. He walked us through the history of NAD therapy, its powerful applications in mental health and addiction recovery, and how methylene blue works alongside it to boost mitochondrial energy. If you haven't listened to Part 1 yet, it's a great place to start. This week, the conversation goes deeper into the practical side of longevity. Alexander shares the lifestyle habits that can naturally raise your NAD levels — and the everyday choices quietly draining them. From the surprising cellular cost of a single drink of alcohol to the science behind intermittent fasting and why muscle mass is one of your greatest longevity assets, this episode is packed with actionable insight. We also explore how NAD Clinic approaches performance optimization through tools like VO2 max breath testing, and what it means to turn data into something you can actually act on. Whether you're new to longevity science or already building your wellness stack, this episode will meet you where you are. If you're ready to stop guessing and start understanding what your body actually needs to thrive, this episode will give you a science-backed, practical roadmap to get there.

Ep 10. NAD for Longevity: How to Boost Energy, Test Your Levels and Slow Ageing

Guest: Alexander J. Audette | Chief Science Officer | NADclinic Alexander Audette is a Canadian biomedical researcher and clinician with over 20 years of international experience. He trained in Chemical Engineering at McGill University before completing advanced study in Acupuncture and Traditional Chinese Medicine at Beijing University, where he also spent seven years studying martial arts. He is a published author in the Journal of Orthomolecular Medicine and currently serves as Chief Science Officer for NADclinic Japan, where he focuses on NAD+ therapy and cellular energy metabolism. NAD is one of the most important molecules for your energy, ageing and long-term health, yet most people have never actually tested their levels. In this episode, Alexander walks us through what NAD is, why it naturally declines as you get older, and what that means for your energy, brain function and overall longevity. You'll learn how supplementation works, the different ways you can take NAD, and why testing your levels first is so important before you begin. We also explore tools like methylene blue and how it supports your mitochondrial health, especially when it comes to energy production and neurodegenerative conditions. But this isn't just about supplements. Alexander shares how your daily habits and lifestyle choices play a key role in maintaining healthy NAD levels over time, so you can support your body in a more sustainable way. If you're looking to improve your energy, think more clearly, and take a more proactive approach to your long-term health, this episode will give you a clear and practical place to start.
