Dr Glenn McConell chats with Dr Edward Chambers from Imperial College London who is an expert on the gut microbiota, exercise and metabolism. He has shown that some fibre can be fermented to short chain fatty acids (SCFA) by gut microbiota which can influence skeletal muscle metabolism. In addition, these SCFA can affect appetite. He has also shown that exercise and/or carbohydrate ingestion reduces appetite. Important message, eat the recommended amount of fibre. Very interesting work and a fun chat.0:00. Introduction2:21.

Outro (9 seconds)Inside Exercise brings to you the who's who of research in exercise metabolism, exercise physiology and exercise’s effects on health. With scientific rigor, these researchers discuss popular exercise topics while providing practical strategies for all.The interviewer, Emeritus Professor Glenn McConell, has an international research profile following 30 years of Exercise Metabolism research experience while at The University of Melbourne, Ball State University, Monash University, the University of Copenhagen and Victoria University.He has published over 120 peer reviewed journal articles and recently edited an Exercise Metabolism eBook written by world experts on 17 different topics (https://link.springer.com/book/10.1007/978-3-030-94305-9).Connect with Inside Exercise and Glenn McConell at:Twitter: @Inside_exercise and @GlennMcConell1Instagram: insideexerciseFacebook: Glenn McConellLinkedIn: Glenn McConell https://www.linkedin.com/in/glenn-mcconell-83475460ResearchGate: Glenn McConellEmail: glenn.mcconell@gmail.comSubscribe to Inside exercise:Spotify: shorturl.at/tyGHLApple Podcasts: shorturl.at/oFQRUYouTube: https://www.youtube.com/@insideexerciseAnchor: https://anchor.fm/insideexerciseGoogle Podcasts: shorturl.at/bfhHIAnchor: https://anchor.fm/insideexercisePodcast Addict: https://podcastaddict.com/podcast/4025218Not medical advice
