The New Macro Factor Web Site

Today’s episode begins with a spoiler in the Feats of Strength segment, as we discuss the winner of this year’s World’s Strongest Man competition. After that, Eric presents a Research Roundup segment about buffering strategies. The segment is mostly about new research on beta-alanine and a couple of related ingredients (carnosine and anserine), but also includes discussions about hyperventilation and the mechanisms involved with various buffering strategies. After that, Greg discusses his newest article on the MacroFactor website, which is called “The Problems with Calorie Counting.” It explores the shortcomings of many common strategies implemented by calorie counters, such as aiming for generic calorie targets or using wearable technologies or predictive equations to estimate energy expenditure. Finally, the show closes with a music recommendation from Eric, and some interesting lichen facts presented by Greg.
