Acute effect of an exogenous ketone monoester supplement on appetite and food intake in adults with type 2 diabetes.

The effects of exogenous ketones on appetite and food intake remain elusive, especially for people with type 2 diabetes (T2D). This study aimed to determine whether acute ingestion of an oral ketone monoester supplement (KME) affected appetite sensations, prospective food consumption and intake in T2D. Results showed that acute KME ingestion did not significantly alter appetite scores. However, there was a tendency for lower energy intake during an ad libitum meal 3 h following ketone ingestion compared to non-energetic placebo. Further research is warranted to understand the long-term effects of exogenous ketones for energy and macronutrient intake in T2D.
