STAK STUDY
CURRENTLY RECRUITING
Variations in Ketone Metabolism (VKM) [STAK-VKM]
This study is being done to see how individuals respond to a ketone ester across different age groups and health statuses. With the ketogenic diet becoming more popular, research on ketones (a molecule created when fat is broken down in the body) has grown as well. It is now possible to increase blood levels of ketones by ingesting them directly instead of decreasing the carbohydrates you eat or fasting for a long time. When ketones are consumed, they are quickly absorbed and increase blood levels of ketones, even in those who are not eating a very low-carbohydrate diet. Since they are so new, very little work has been done to show what level of ketone supplements are best for individual people. These findings will be used to help develop future research studies and help others to pick the right doses of ketone supplement.

John Newman, MD, PhD
John Newman, MD, PhD, is an Assistant Professor at the Buck Institute for Research on Aging and an Associate Professor in the Division of Geriatrics at University of California San Francisco (UCSF). His career goal is to translate our expanding understanding of aging biology to improve the care and help maintain the independence of older adults. His research at the Buck Institute studies the molecular details of how diet and fasting regulate the genes and pathways that in turn control aging, focusing on the ketone body beta-hydroxybutyrate and how its molecular signaling activities involving epigenetics and inflammation regulate aging and memory in mice.
Dr. Newman is also a geriatrician who cares for hospitalized older adults at UCSF and the San Francisco VA Medical Center, focusing on preserving mobility and preventing delirium.
Brianna Stubbs, PhD
Dr. Stubbs is a world expert in exogenous ketone metabolism and its implications for performance, resilience and health-span. She completed her PhD in Metabolic Physiology at the University of Oxford, studying the metabolism and the application of exogenous ketone salts and esters. Whilst completing her studies, she competed on the British International Rowing Team, and was a two-time World Champion lightweight athlete. Brianna is currently Lead Translational Scientist in the Business Development Team at The Buck Institute for Research on Aging where she is focused on the translation of ketone body research into consumer products and drugs that target healthy aging.
