Study Overview
Brief Summary
Evaluate the capacity of different dietary supplements to increase ketone production in healthy adults.
Detailed Description
The aim of this study is to evaluate the capacity of different dietary supplements to increase ketone production in healthy adults. Each supplement (leucine, butyrate, octanoate, carnitine or butter fraction rich in MCT) is evaluated for a period of 4-hour during which multiple blood samples are taken in order to measure ketone production.

Outcomes
Primary Outcomes
Concentration of Total Plasma Ketones
Time Frame: 4 hours
Difference from Time 0 in Total ketones = acetoacetate (umol/L) + beta-hydroxybutyrate (umol/L) Time 0 is when the participants arrived, after a 12 hours fast, i.e. before the breakfast. Plasma was collected every 30 minutes for 4 hours immediately following breakfast (where supplements were taken). Results are the mean of plasma ketones measured every 30 minutes ( i.e. total of 9 plasma samples) for the 4 hour period. For each time point, the difference form time 0 has been made. So this is the mean of the difference from time 0 in total ketones. Data were not collected for the 'Intervention 8: 65 g of butter fraction rich in MCT' supplement.
