Study Details

Study Description

Brief Summary

Participants will undergo 3 Positron Emission Tomography (PET) scans in 3 different conditions :

  1. Fasting without exogenous ketone salt

  2. Fasting with exogenous ketone salt supplement

  3. Post-Prandial with exogenous ketone salt supplement.

Condition or Disease Intervention/Treatment Phase
  • Dietary Supplement: Fasting with exogenous ketone salt supplement
  • Dietary Supplement: Post-Prandial with exogenous ketone salt supplement
N/A

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 :

  1. Fasting without exogenous ketone salt

  2. Fasting with exogenous ketone salt supplement

  3. Post-Prandial with exogenous ketone salt supplement.
