Full show notes: https://bengreenfieldlife.com/adaptive Why do some people get stronger, leaner, and more adaptable under stress, while others burn out doing the exact same things? In this episode with Dr. Cody Strodtman, a naturopathic doctor, acupuncturist, and author of Your Life, Your Choice: The Rise of Adaptive Medicine, we explore how your body actually adapts to stress—and why missing the right inputs keeps your system from responding the way it should. Here’s what we cover: - How circadian biology is shaped by three key ratios: light and darkness, movement and rest, eating and fasting - The difference between time-restricted eating and chronic calorie restriction—and how each affects hormones and metabolism - How improving carbon dioxide (CO₂) tolerance supports blood flow, calmness, and nervous system regulation - Why intermittent hypoxia enhances mitochondrial function, stem cell activity, and stress adaptation - How targeted cold exposure is used clinically—from recovery protocols to protection during chemotherapy - How sodium and bicarbonate support performance, buffer acidity, and reduce fatigue during fasting or ketosis If you want a more complete framework for building a body that performs—from sleep and metabolism to breathwork and recovery—this episode is worth your time. 📲 Check out my FREE Top Health Community! - https://joinlifenetwork.com 💊Shop My Curated Marketplace of Vetted Products! - https://shoplifemarket.com 🏋️Sign up for a FREE Coaching Call! - https://jointriumphcoaching.com 📩 Check out my FREE newsletter! - https://bengreenfieldlife.com/newsletter/ 🔗My Website: https://bengreenfieldlife.com/ 🔗My Podcast: https://bengreenfieldlife.com/podcast/ 🔗My Books: https://shopbengreenfieldlife.com/collections/books Connect with me: ⬇️ Instagram https://www.instagram.com/bengreenfieldfitness/ Facebook https://www.facebook.com/BGFitness X https://twitter.com/bengreenfield TikTok https://www.tiktok.com/@bengreenfield 00:00 Health vs Disease Basics 00:20 Meet Dr Cody Stroman 01:38 What Is Adaptive Medicine 05:27 Circadian Rhythm Ratios 06:51 Travel and Meal Timing Hacks 09:56 Intermittent Fasting Clarified 12:04 Inspiratory Muscle Training 16:06 CO2 Tolerance and Calm 19:29 CO2 Devices and Therapy 24:14 Intermittent Hypoxic Training 25:57 Adapter Breath Protocol 29:55 Measuring Hypoxia Safely 30:38 DIY Oxygen Cycling Hacks 31:40 Cold Therapy Routine 34:12 Cold For Chemo Side Effects 37:17 Fasting And Cancer Metabolism 43:30 Heat As Heart Medicine 48:24 Carnivore And Plant Hormesis 51:52 Baking Soda Fasting Trick 55:02 Flexibility And Pain Science 56:17 Voodoo Flossing Mobility 58:01 Wrap Up And Resources
