Ketoses, Metabolic, Type 2 Diabetes
Conditions
Brief summary
The main objective of this clinical trial is to study the effects of orally administered ketone drinks containing the ketone body, 3-hydroxybutyrate (3-OHB), just before a meal in patients with type 2 diabetes. Moreover the investigators will compare the effects of two different ketone drinks. The hypothesis is: 3-OHB as a pre-meal may: * Lower postprandial blood glucose and lipids. * Mediate release of intestinal hormones and affect gastric emptying. * Affect appetite and other subjective measures related to food intake. The effects of 3-OHB as a pre-meal will be investigated by blood samples, isotopic tracers examinations, paracetamol test, questionnaires and meal test.
Interventions
Orally administered pre-meal drinks.
