Effects of Ketones on Brain Energetics and Alcohol Consumption in Alcohol Use Disorder

Drink a single dose of ketone supplement 25g, three times, randomly given at 1 of 2 MRI scan visits, 1 of 2 FDG PET/CT scan visits, and 1 of 2 alcohol bar lab visits.

Each subject will undergo 2 research MRI scan evaluations of the brain (up to 90 min.). The MRI is FDA-approved 7.0T Magentom Prisma scanner (Siemens Medical Solutions USA, Inc., Malvern, PA) with an approved radiofrequency head coil.

Each subject will undergo 2 FDG PET/CT scans. FDG is a positron emitting radiopharmaceutical. In addition to the radioactive FDG tracer, a low-dose CT of the chest is typically performed with the FDG PET/CT for the purpose of anatomical registration and attenuation correction of PET images. There are no separate diagnostic CT scans performed as part of this study.

Each subject will undergo 2 alcohol bar labs. Subjects will drink about 2 ½ standard alcohol beverages, based on their weight to reach a breath alcohol level of 0.050%.

Drink a single dose of placebo beverage, that will look and taste the same as the ketone supplement. Subjects will recieve the beverage three times, randomly given at 1 of 2 MRI scan visits, 1 of 2 FDG PET/CT scan visits, and 1 of 2 alcohol bar lab visits, opisite of the Kenetik beverage.
