Brief Summary

Hyperglycemia following meals in patients with type 2 diabetes mellitus (T2DM) is a common problem. Recently, our group found that oral consumption of the ketone metabolite, 3-hydroxybutyrate (3-OHB), effectively stimulates insulin secretion and delays gastric emptying.The aim of this study is to investigate the dose/response relationship between 3-OHB servings of 0, 10, 20 and 40 grams 30 minutes before an OGTT and, ii) investigate the role of timing by serving 20 grams of 3-OHB at different timepoints ahead of an OGTT (0, 30 and 60 minutes)

Outcome Measures

Primary Outcomes (1)

  • Blood glucose following the OGTT

    Change in blood glucose following the OGTT and compared between the different visits. Incremental change (delta) from baseline to peak. Measured with laboratory kits.

    Blood samples will be obtained -60, -30, -15, 0, 15, 30, 45, 60, 90, 120, 150, 180 minutes from the OGTT

Secondary Outcomes (1)

  • Plasma concentrations of 3-OHB, insulin, C-peptide, glucagon like peptide-1 (GLP-1), cholecystokinin (CCK), acetaminophen, free fatty acids along others.

    Blood samples will be obtained -60, -30, -15, 0, 15, 30, 45, 60, 90, 120, 150, 180 minutes from the OGTT
