The Effect of a Ketone Drink on Liver Glucose Production in People With Type 2 Diabetes

Overview

What is the effect of a ketone drink on liver glucose production, and postprandial glycemia, in people with type 2 diabetes.

Background: Ketones are molecules that are naturally produced by our body during fasting or diets low in carbohydrates. Ketones can affect how our liver produces and maintains our body's blood sugar levels, which could be important in the management of type 2 diabetes (T2D), where high blood sugar levels are partly because of excess sugar production by the liver. Objectives: To determine if, and how, a ketone drink can lower blood glucose in people with T2D following a meal. Methods: Twelve people with T2D will visit our laboratory in the morning on two occasions and ingest a drink containing ketones or placebo on each visit in a random order before ingesting a milkshake style drink containing sugar. Blood samples will then be taken at regular intervals over 4 hours to determine if the ketone drink has lowered blood sugar levels in response to the meal, and if this was due to reduced sugar production by the liver. Value: This research will provide new knowledge about the regulation of liver blood sugar production in response to ketone ingestion. This may also inform future clinical trials to establish if ketone drinks could be used as a treatment for T2D.
