Iron Culture presented by MASS

Eric Trexler and Eric Helms recently found themselves in the middle of a debate about optimal protein intakes, all initiated by a social media post from Stu Phillips (a leading researcher in the area). In this episode, they dive into how that scientific discourse played out, the nuances of protein intake, and the implications for recreational lifters and bodybuilders alike. They discuss the complexities of scientific data interpretation, public messaging, and practical recommendations for optimal protein consumption.

Back in episode 375, Helms and Trex briefly mentioned a few "evidence-based fitness" topics for which their views have evolved over the years. In hindsight, they didn't give a few of those topics the time, attention, and explanation they deserve. So in this episode, Helms and Trex take a closer look at two key topics: maximum recoverable (or adaptable) training volume, and various approaches to strategically manipulating leptin levels (such as refeeds and diet breaks).

Join us for a rare Iron Culture episode with co-hosts who are not only on the same continent, but actually in the same ROOM. Helms and Trexler are in Australia for the Sports Nutrition Association Annual Conference, so they got together to record an episode about Trex's presentation topic: resistance to weight loss. Specifically, why being a true "outlier" who is resistant to weight loss efforts is quite rare, particularly when looking at the energy expenditure side of the equation.
