Guest Bio

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
