Exercise and type 2 diabetes with Dr John Hawley

13 snips

Sep 15, 2022

Dr John Hawley, Professor of Exercise Metabolism, discusses exercise and type 2 diabetes. They explore the benefits of exercise snacking, intensity levels, muscle glucose uptake during exercise, and the challenges of following diets. They also touch on time-restricted eating, continuous glucose monitoring, circadian biology, and the individual nature of exercise. The podcast highlights the importance of breaking inactivity, the significance of intensity, and the potential benefits of afternoon exercise for glucose control.

Dr Glenn McConell chats with Professor John Hawley from the Australian Catholic University on Exercise and type 2 diabetes. John is one of the most recognized names in exercise metabolism. He has published over 300 journal articles (Google scholar: 40,000 citations, H index 113). We discussed many things (see time stamps below).

Inside Exercise brings to you the who's who of 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).
