Ep. 243 - Exercise Energy Compensation: It's Not JUST About Calories (ft. Eric Trexler)

This is a monster episode. Newly added co-host Eric Trexler details his impressive credentials, groundbreaking new line of research and perhaps most importantly, the best way to effectively execute a single leg take-down on an unsuspecting person.  His new appointment at Duke University will be looking in part at the topic of today, exercise energy compensation. It turns out that calories in, calories out is a little more complicated than most would assume. Made famous by Dr. Herman Pontzer and his book Burn, Dr. Trexler explores what exactly this phrase means, the utility of doubly labelled water and the future of research in this field.   00:00 Officially welcoming Eric (Trexler) to the holy trifecta 06:14 Trexler’s background and what’s in store for Helms Hall 2013 Diet versus exercise in "the biggest loser" weight loss competition https://pubmed-ncbi-nlm-nih-gov/23404767/  Hall 2022 Energy compensation and metabolic adaptation: "The Biggest Loser" study reinterpreted https://pubmed.ncbi.nlm.nih.gov/34816627/ 18:11 Trexler’s training story 29:25 Why Trexler doesn’t like Dr Grant Tinsley (scandal) and the passion for exercise science 32:27 Trexler the researcher and exercise energy compensation 39:08 Explaining Doubly Labelled Water 43:28 The overarching aim of Trexler’s research and the role of exercise in weight loss Speakman 2019 The International Atomic Energy Agency International Doubly Labelled Water Database: Aims, Scope and Procedures https://pubmed.ncbi.nlm.nih.gov/31743893/ 1:02:40 Negative energy balance and energy expenditure compensation MASS Research Review https://massresearchreview.com/  Willis 2022 Physical Activity and Total Daily Energy Expenditure in Older US Adults: Constrained versus Additive Models https://pubmed.ncbi.nlm.nih.gov/34334719/ 1:13:20 Compensatory mechanisms with negative energy balance Speakman 2020 Why does caloric restriction increase life and healthspan?

Om Podcasten

Iron Culture was started by Eric Helms and Omar Isuf as a means of exploring the world of physical culture and attempting to distill a unified philosophy of lifting and to help listeners find greater meaning from the iron. The lifting community has become fractured over the last ~70 years and this Podcast will attempt to explore the fundamental threads that unite these different tribes. The Podcast focuses on dispensing practical, useful information to the listener, bouncing from history, to philosophy, to contemporary lifting culture issues, to science. This can range from teaching the audience about lifting, programming, nutrition, supplements/PEDs and the history of lifting culture. The format includes casual conversations between the two hosts on a variety of topics, discussions with a panel of experts and interviews with authoritative figures in the lifting community.
