Study type | Interventional |
The study investigators hypothesize (1) that the SCFA/acetate metabolism differs between metabolic phenotypes and (2) that using a mixture of fibres that differ in degree of polymerization and branching namely a resistant starch and a human-like milk oligosaccharide enhance the acetate availability in the distal colon and systemic circulation, consequently leading to its metabolic effects. To study this, the investigators will supplement lean, normoglycaemic vs. overweight/obese, prediabetic men with the fibre mixture the day before the clinical investigation day (CID) and study during the CID its effects on fasting and postprandial substrate and energy metabolism.
