The primary objective of this study is to investigate the acute physiological and metabolic effects of ingesting the short-chain fatty acids (SCFA)s propionate (three carbon atoms long; C3:0) and butyrate (C4:0) in healthy men and women. This aim will be addressed through a block-randomized cross-over study including two visits with acute intake of propionate and butyrate, respectively. The hypothesis is that plasma ketone body levels will increase during the first three hours after intake of butyrate, but not propionate, in healthy individuals in the overnight fasted state.
