In this article, exogenous ketone supplements have been shown to be effective in stimulating ketosis, which can be used to provide energy to the brain during periods of low glucose availability, as well as in other tissues. Researchers have investigated the effects of acute ingestion of the ketone monoester on the postprandial glycaemic response in young, healthy individuals. They found that the ketone monoester resulted in a significant reduction in plasma glucose area under the curve by 16% over the 2-hour period, without further elevating insulin compared to glucose alone. This result may have potential implications for individuals with type 2 diabetes mellitus.
