Detailed Description
This study will help to quantify heart and kidney ketone uptake with or without an exogenous ketone salt with or without food intake in middle-aged adults. Participants will have 3 different PET scan to perform :
-
Fasting without exogenous ketone salt
-
Fasting with exogenous ketone salt supplement
-
Post-Prandial with exogenous ketone salt supplement.
