In this episode of Iron Culture, hosts Eric Helms and Michael Zourdos engage in a deep discussion with Dr. Mike Ormsbee about the role of resistance training in fat oxidation and body composition. They explore how resistance training can be an effective tool for fat loss, the physiological mechanisms behind fat metabolism during exercise, and the importance of myokines and hormones in this process. The conversation challenges common perceptions about fat burning and emphasizes the need for a nuanced understanding of energy expenditure and body composition changes. In this conversation, Michael Zourdos and Mike Ormsbee delve into various aspects of nutrition and exercise science, emphasizing the importance of understanding the evolving nature of research. They discuss the significance of preclinical studies, the role of resistance training in fat loss, and the myth of spot reduction. The conversation also explores the interplay between glycogen and fat utilization, the implications of pre-sleep protein feeding, and the lessons learned from past research mistakes. The speakers highlight the need for collaboration in research and the ongoing exploration of nutritional timing and its effects on body composition and sleep quality.
