Be Healthier and Perform Better with Metabolic and Physiological Flexibility | #79 ft. Mike T. Nelson

1 hour 48 minutes

In this episode of the Critical Oxygen podcast, Dr. Mike T. Nelson and I discuss metabolic and physiological flexibility, and explore their significance in human performance and health. We discuss the importance of being able to switch between carbohydrate and fat metabolism, the role of exercise in enhancing metabolic flexibility, and the implications of research findings on variability in metabolism. The conversation also touches on practical applications for athletes and individuals looking to optimize their metabolic health through tailored training and nutrition strategies. In this conversation, we discusses the importance of metabolic and physiological flexibility, mitochondrial health, and the role of exercise in enhancing metabolic adaptation. We emphasize the significance the concept of physiological flexibility, which includes temperature regulation, pH balance, and oxygen/CO2 management. The discussion highlights the interconnectedness of these physiological systems and the necessity of a balanced approach to training and recovery.

TAKEAWAYS

- Metabolic flexibility is the ability to switch between carbohydrate and fat metabolism.

- Exercise plays a crucial role in enhancing metabolic flexibility.

- Insulin acts as a fuel selector switch in the body.

- Physiological flexibility involves maintaining temperature, pH, and gas exchange in the face of greatly changing stress environments.

Enjoy!
