## Resource

Exogenous ketones have exploded in popularity, with claims ranging from better brain function to improved performance and weight loss. But what does the science actually say? In this in-depth conversation, Dr. Bret Scher sits down with leading ketone researcher Dr. Dominic D'Agostino to break down the reality behind exogenous ketones—what they are, how they work, and where they may (or may not) fit into your health strategy. They explore the key differences between: Endogenous ketones (produced by your body through diet or fasting) Exogenous ketones (supplements you consume) And why that distinction matters for both metabolic and brain health. This conversation covers: The different types of exogenous ketones (salts, esters, those derived from MCTs) Potential benefits for brain energy, seizures, and metabolic health Safety considerations and why formulation matters Why exogenous ketones are best viewed as a tool, not a replacement for a ketogenic diet The concept of a “sweet spot” for ketone levels in different conditions One of the biggest takeaways: context is everything. Exogenous ketones may offer the most benefit when used to support a well-formulated metabolic approach, rather than as a standalone shortcut. Dr. D’Agostino also shares insights from decades of research, including work with the Department of Defense, and discusses where the science is headed, especially in areas like neurological and psychiatric conditions. 👉 Learn more about the growing body of research on ketogenic therapy and mental health on our clinical trials page: metabolicmind.org/resources/science/clinical-trials/ 🔎 Have questions about how to apply metabolic therapies effectively?
