Iron Culture Podcast | Ep. 254- Do Fat Burners Actually Work!? @IronCulturePodcast | Uploaded December 2023 | Updated October 2024, 4 hours ago.
Happy Holidays cultists! We sincerely thank you all for joining us every week to explore the history, science and culture of the iron and we look forward to doing it more in 2024! In this episode, Omar and Helms discuss fat burners: supplements that supposedly enhance fat loss either by increasing energy expenditure and/or by blunting hunger and reducing energy intake. You’ve probably seen dozens marketed over the years if you’ve been around the fitness industry for any decent length of time, but do they actually work? In this episode we discuss the science of fat burners. A recent study coming out of none other than Dr. Grant Tinsley’s lab showed that a commercially available thermogenesis fat burner did seem to do something, but how meaningful it was and whether it actually would lead to fat loss is up for debate. Finally, we discuss where the data lies broadly on this whole class of supplements.
