“Comparison of the Short-Term Effect of Dietary Carbohydrate Restriction Versus Exogenous Ketone Supplementation on Myocardial Glucose Suppression and Timing to Achieve a State of Ketosis Using FDG PET/CT Serial Imaging”

The purpose of this study is to test different methods of preparation that can be used prior to a test called an FDG PET/CT scan. FDG PET/CT scans are routinely done for evaluation of heart inflammation. Standard preparation for the scan includes a ketogenic (high fat and low carbohydrate) diet for 24 hours and overnight fasting to help suppress the amount of sugar taken up in the heart muscle. However, Investigator still do not know if this preparation is the most effective method. So the Investigator, want to investigate alternative methods for decreasing the amount of sugar uptake seen in the heart during FDG PET/CT scan, thus, investigator will have participants try up to 3 different methods of preparation prior to the FDG PET/CT scans to see which type of preparation works the best.

Drug - FDG

FDG is a FDA approved radiotracer which each subject will have 3 positron emission tomography/computed tomography (PET/CT) scan performed.

Dietary Supplement - Ketone Drink

Subjects will undergo FDG PET/CT after 1 dose of ketone drink administration after 12 hours of fasting prior to FDG injection. The dosing of ketone drink administration (approximately 65 mL) will be weight based (714 mg/kg), which is crucial to replicating ketone levels between participants

Ketogenetic Diet

Subjects needs to be on Ketogenetic diet
