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
