Trey Suntrup, PhD is a product engineer who earned his doctorate in physics and electrical engineering from the University of California, Santa Barbara in 2015. He is currently the Head of Product at Readout Health, the St. Louis startup that recently launched the Biosense breath ketone meter. Following a successful clinical trial in the autumn of 2019, Biosense has entered the consumer, clinical, and research market as a tool to help those wanting to lose weight or manage blood glucose with a ketogenic diet.

On this podcast, Trey discusses breath acetone testing and how it can be used to improve health outcomes. He shares the results of the clinical trial supporting the Biosense meter, including the finding that measurements must be collected multiple times daily to truly evaluate the benefit of a ketogenic or intermittent fasting plan. He also describes some of the advantages of breath testing over blood ketone measurement.
