Individual Responses to Training and Protein Quality

It’s very common to assume that group-level findings from research will reliably predict how you (or your clients) will respond to a particular training strategy, but that’s not always the case. In today’s episode, Greg discusses the substantial amount of inter-individual variability observed in responses to training interventions, and how to navigate training decisions in light of these hard-to-predict differences among individuals. After that, Eric discusses protein quality: what it is, what affects it, and how much it does (or doesn’t) matter from a practical perspective. His segment summarizes the research directly comparing a wide range of protein sources, and provides practical strategies for protein source selection in vegan, vegetarian, and omnivorous diets.
