SNR #277: Eric Helms, PhD - Non-Quantitative Dieting, Personal Experiments & Optimal Weight Gain for Hypertrophy
Eric is currently a Research Fellow at Auckland University of Technology, New Zealand. His work is focused on training and nutrition interventions that could have implications for bodybuilders, powerlifters and other strength athletes. Eric has many peer reviewed publications and currently has many ongoing research projects and collaborations. Previously, Eric completed his PhD at AUT. He also holds a BS in fitness and wellness, an MS in exercise science, and a MPhil in sports nutrition. For the better part of his career he’s been a coach at 3D Muscle Journey, working with drug free strength and physique competitors at all levels. Eric, along with Greg Nuckols and Dr. Mike Zourdos, created the monthly reserach review MASS (Monthly Applications in Strength Sports), which breaks apart some of the recent research carried out that is relevant to strength athletes, bodybuilders and powerlifters. He is also the author of the highly popular Muscle & Strength Pyramids set of books. As an athlete, Eric has competed as a bodybuilder and powerlifter. This year (2019) he returns to the bodybuilding stage for the first time in eight years, for his fourth competition season. In This Episode We Discuss: Ongoing trial looking at effects of differnt sizes of caloric surplus for muscle gain Eric’s unconventional appraoch to his current contest prep Non-quantitative tracking and assessment of progress Applying lessons from bodybuilding to other areas of life SHOW NOTES: https://sigmanutrition.com/episode277/
SNR #272: Barbora de Courten, PhD – Effect of Carnosine on Glucose Metabolism and Chronic Disease Risk
Professor Barbora de Courten, MD PhD FRACP MPH is a Professor at Monash University, Australia. She is a National Heart Foundation Future Leader Fellow and a specialist physician with a PhD in epidemiology, extensive training in clinical trials (NIH) and a Master of Public Health (Monash University). She has expertise across the translational research continuum from epidemiology, human mechanistic studies to clinical trials and public health interventions through to practice. She is passionate about research into holistic approaches to prevention and treatment of chronic diseases by promoting health through safe, low-cost and easily scalable interventions with the potential to have an immediate public health impact to prevent and treat chronic diseases. She believes this will impact not only health of individuals but also be beneficial to our society and environment we live in. Her vision is to establish new strategies for prevention and management of chronic diseases, specifically obesity, diabetes and cardiovascular disease. Her goal is that her research findings will ultimately translate into treatment guidelines, reduced diabetes and cardiovascular morbidity and mortality and reduced healthcare costs. In This Episode We Discuss: --> Mechanisms by which certain behaviours (inactivity, poor diet, smoking, etc.) increase chronic disease risk: inflammation, oxidative stress and advanced glycation (AGE formation). --> What is carnosine? --> How might carnosine supplementation reduce risk? --> Dosage and timing used in trials to date --> Prof. de Courten’s trial showing improvements in insulin sensitivity and an oral glucose tolerance test --> As beta-alanine works by increasing muscle carnosine concentration, could it be useful for the health?

SNR #271: Prof. John Hawley – Circadian Metabolomics & Time-Restricted Feeding
Prof. Hawley is Director of the Mary MacKillop Institute for Health at Australian Catholic Universtiy in Melbourne, Australia. He has published over 220 scientific manuscripts, written over 100 articles for technical journals and has authored numerous book chapters for exercise biochemistry and sports medicine texts. He is an Associate Editor for Diabetologia and currently sits on the Editorial Boards of many international journals. He is a frequently invited speaker at both National and International scientific meetings. John’s primary research focus includes the interaction of exercise and diet on the regulation of fat and carbohydrate metabolism, particularly within skeletal muscle, the molecular basis of exercise training adaptation and the cellular bases underlying exercise-induced improvements in insulin action. In This Episode We Discuss: --> Current work being done by Prof. Hawley’s lab on circadian metabolomics Defining the human metabolome and circadian metabolomics --> Comparative analysis of the circadian metabolome in the serum versus peripheral tissues (i.e., skeletal muscle) --> Impact of high-fat or high-carb diet on the daily variation in metabolites --> How dietary intake is a strong zeitgeber for peripheral clocks --> Tissue-specificity of the human circadian metabolome --> Time-restricted feeding in animal models and in humans Join the Sigma Synopsis for free: https://sigmanutrition.com/sigma-synopsis/

Another brilliant episode !! I wondered if you would consider doing an episode/discussing how to know what probiotics are recommended for different conditions. I have had my gallbladder removed and suffer with poor digestion and would love to hear more about what I can do to help digestion and possibly what probiotics are recommended for this. Thanks, Maria

Just found your podcast loving it so far, ATP science is my other favourite but they are also selling products so it is a little bit tainted in that way. your podcast is refreshing because you aren't trying to sell me anything. excepting maybe your guests or sponsors but there's no getting around that. thanks for the hard work love it. p.s. is it possible to have your patreon link in the description on castbox?
