Ep 377 – MRV/MAV, Diet Breaks & Refeeds

from Iron Culture presented by MASS Hosted by MASS Research Review

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). Iron Culture is proudly presented by the MASS Research Review. Mostly because Helms and Trex are co-owners. massresearchreview.com Chapters 00:00 Intro 04:11 The origins of MRV/MAV 07:08 Updated perspectives on MRV/MAV 14:26 Practically applying MRV/MAV 17:11 Helms’ current volume adjustments 24:30 Updating models in science 29:20 The importance of leptin 32:42 The origins of Trex’s interest in manipulating leptin 38:47 Running studies on diet breaks and refeeds 44:27 Recent meta-analysis on intermittent dieting strategies 50:19 Trex’s current perspective on refeeds and diet breaks 53:47 Behavioral versus physiological effects 59:09 Contextual use of intermittent dieting 1:06:34 Wrapping up
