Ep. 267 - Addressing Data Fraud in Nutrition Science

The holy trinity is back and holy smokes do we have a Holy Ghost of an episode! First, to kick things off the crew discusses the recent “March madness” of powerlifting that just finished: IPF European Champs, the UK Arnold, and Powerlifting America Nationals. Some absolutely stunning performances occurred all over the world in powerlifting and it seems the rising tide of talent has no end. Then we get into the meat - or should I say the bottomless soup - of the episode. While fraud in research is exceedingly rare, it does happen, and unfortunately, more common issues such as p-hacking are a far more prevalent issue. What is to be done in situations like this? One tool, as the Erics discuss, is replication. 00:00 An intro in unison (as always) and Trexler the bouncer MASS Research Review https://massresearchreview.com/ Raskol Apparel https://raskolapparel.com/ 10:20 Introducing more Trex lore 14:42 Powerlifting America Nationals, Arnold UK, and IPF European Champs recap 34:45 Trexler yawn-gate rears its head again and some numbers behind tzhe sport 54:37 Trexler’s return and getting into the science of replication  1:10:08 The bottomless soup bowl Wansink 2005 Bottomless bowls: why visual cues of portion size may influence intake https://pubmed.ncbi.nlm.nih.gov/15761167/ Lopez 2024 Visual cues and food intake: A preregistered replication of Wansink et al.

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.
