666: Mastering Nutrition: How to Think Clearly About Diet in a World of Conflicting Advice with Christopher Masterjohn

Author: Celebrity Fitness Trainer & Longevity Enthusiast Ted Ryce March 16, 2026 Duration: 58:15

Nutrition debates today often feel more ideological than scientific. One of the biggest examples is the ongoing controversy around seed oils, where strong opinions exist on both sides but clear understanding is often missing. 

In this episode, Ted speaks with nutrition scientist Christopher Masterjohn to explore the history and research behind seed oils, cholesterol, fatty liver disease, and oxidative stress. They also discuss why nutrition debates become polarized, how choline intake influences liver health, and why metabolic markers like glucose and lactate can offer useful insights into personal metabolism.  

If you want a deeper, more nuanced understanding of one of the most debated topics in nutrition—and practical ways to think about your own diet—this conversation will challenge assumptions and expand your perspective. Listen now.
