Circadian Rhythm Saved My Life (EP 106)

If you’ve ever done all the “right” health things and still felt awful, Jason Yun’s story is going to sound uncomfortably familiar. He was the textbook gym owner: 4:30 am alarms, 5:15 am classes, late‑night sessions, massive smoothies, and bodybuilding nutrition that looked impressive on paper but quietly wrecked his hormones, sleep, and mental health. Behind the scenes, he went from chasing muscle and performance to dealing with a popped back on a deadlift, losing about 70 pounds, spiraling into severe depression, and battling weekly suicidal thoughts while still being “the health guy” for his clients. In our conversation, Jason opens up about napping in his car just to survive the next class, living on expert diet rules and supplements, and still ending up with upside‑down cortisol, wrecked melatonin, and a body that couldn’t keep up. That’s the line where he finally said, “enough” and went all in on circadian rhythm, light, and what he calls Mito hacking. We dig into why late‑night eating crushed his sleep, how sunrise with naked eyes started normalizing his hormones in weeks, and why timing, light, and simple daily rhythms might matter more than your macro spreadsheet or the latest stack. === Chapter 00:23 Introduction 01:45 Sunlight, Sunscreen, and Sunglasses 08:28 Safe Sun Exposure Strategies 12:06 What Is Mito Hacking? 17:43 Skepticism and Bioharmonizing 21:39 The Improvement Warrior Mindset 24:11 Seasonal Eating and Circadian Nutrition 26:51 How Fast Changes Show Up 27:39 Light Over Food and Exercise === Guest: Jason Yun, Improvement Warrior Fitness Website: https://www.improvementwarriorfitness.com LinkedIn: https://www.linkedin.com/in/jasonyun3010 Instagram: https://www.instagram.com/fitnesswithyun === Shout-outs Dr. Jack Kruse, Kruse Longevity Center: https://jackkruse.com/ Ben Greenfield, Ben Greenfield Life: https://www.linkedin.com/in/bengreenfield/ Sarah Kleiner, Sarah Kleiner Wellness: https://www.sarahkleinerwellness.com/ === Resources / Companies / Books / Podcasts The Secret (book): https://amzn.to/4ulEsPE Website: https://play.google.com/store/apps/details?id=com.andymstone.sunpositiondemo MyCircadian App: https://play.google.com/store/apps/details?id=com.mycircadian.app Website: https://www.imdb.com/title/tt0076578 Keto diet: https://www.dietdoctor.com/low-carb/keto Paleo diet: https://thepaleodiet.com/ === MUSIC LICENSE CERTIFICATE: Envato Elements Item Item Title: Healthy Eating Item URL: https://elements.envato.com/healthy-eating-VNN4M4P Author Username: CrazyTunes Licensee: Marvin Bee Registered Project Name: Unhealthy Podcast License Date: January 3rd, 2026 Item License Code: XPFS6HD54W === About the Unhealthy PodcastHosted by Marvin Bee (Uncle Marv), the Unhealthy Podcast dives into real conversations about health, wellness, and everyday habits that impact how we live, work, and age.
