Join me, Dr Mike T Nelson, on the Flex Diet Podcast for an interesting conversation with PhD candidate Nathan Serrano about his groundbreaking review study published in the American Journal of Physiology, Endocrinology, and Metabolism. We explore the intricate ways muscle fiber types, specifically slow-twitch and fast-twitch fibers, impact metabolism and function, particularly in individuals with obesity.

Nathan sheds light on the role of intramuscular triglycerides in carbohydrate metabolism and insulin signaling and the differences between untrained individuals and athletes. We also touch on his research into muscle protein synthesis and how it varies between obese and healthy populations, along with insights from his collaboration with Dr. Andy Galpin.
