SNR #211: Brianna Stubbs, PhD - Ketogenesis, Metabolism and Ketone Ester Supplementation

Brianna Stubbs, PhD In 2016 Brianna completed her PhD in Metabolic Biochemistry at Oxford University. She also became a World Champion rower as part of the GB Rowing Lightweight Women's four person crew, and won 3 other World Rowing Championships medals. She has published peer-reviewed studies looking at ketone metabolism, ketone ester supplementation in athletes and effects of ketones on appetite. In This Episode We Discuss: Brianna's background as an elite-level rower Her PhD research on ketone metabolism Misconceptions about ketones (both endogenous and exogenous) Ketogenesis: why do we make ketones? Brianna's study examining effect of ketone ester supplementation on appetite and ghrelin levels Who needs to even know their ketone concentration? Ketone supplements: glycogen sparing or glycogen impairing? Effect of ketone supplementation on fuel selection in endurance athletes Potential for supplementation: where is the area we will most likely see some benefit? Limitations of current literature base
