3. Supersoldiers and enhanced cognitive function with ketones! A conversation with Dominic D’Agostino, PhD

Metabolic Shifts

The shift to a ketogenic diet triggers significant metabolic changes, primarily through ketone production and utilization. Dominic D’Agostino explains that when carbohydrates are eliminated, blood glucose levels drop, and insulin suppression occurs, leading to increased glucagon and catecholamine levels 1. This process liberates fatty acids from adipose tissue, which are then oxidized in the liver to produce ketones like beta-hydroxybutyrate 1. These ketones are not used by the liver but are distributed to peripheral tissues, including the brain and muscles, which utilize them for energy 2.

The liver produces these ketone bodies but does not use them for fuel.

This metabolic flexibility allows the body to adapt to varying energy sources, enhancing endurance and cognitive function 2.

   

Long-Term Adaptation

Long-term adaptation to ketosis involves significant hormonal and metabolic flexibility changes. Dominic D’Agostino notes that individuals on a ketogenic diet for extended periods often exhibit excellent metabolic health, with adaptations that stabilize blood glucose and enhance metabolic flexibility 3. This adaptation is akin to muscle memory, where the body quickly adjusts to dietary changes, improving efficiency in utilizing ketones and other energy sources 4.

The more you do it, the easier it gets and the more benefits you derive from it over time.

Medium-chain triglycerides (MCTs) play a crucial role in this process, rapidly converting to ketones and supporting sustained ketosis 5.

   

Anti-Inflammatory Effects

Ketones exhibit powerful anti-inflammatory and protective mechanisms, particularly in managing oxidative stress. Dominic D’Agostino highlights that ketones function as histone deacetylase inhibitors, activating antioxidant systems and suppressing inflammatory pathways like the NLRP3 inflammasome 6. This suppression reduces oxidative stress and inflammation, potentially mitigating age-related diseases and enhancing cellular resilience 6.

Ketones have been a powerful regulator of histone deacetylase inhibitors, which activate antioxidant systems.

Additionally, ketones may influence epigenetic regulation, affecting gene expression and contributing to metabolic health 7.
