Science of exercise, mitochondrial health and longevity | Biochemist Kieron Rooney

In Episode #222, I’m joined by Drew Harrisberg and Kieron Rooney, PhD to discuss how the biochemistry of exercise can impact your health. We cover a wide range of topics, including mitochondria efficiency, metabolic flexibility, and fat adaptation. Dr Rooney also offers training advice, and his thoughts on a ketogenic diet. Evidence continuously shows us that the multitude of factors contributing to health and longevity are incredibly complex. Today, Kieran Rooney, PhD sits down with Drew Harrisberg and me to break down the biochemistry behind exercise, exploring both the theory and practical applications of improving your fitness.
