Summary
Brief summary
The study aims to establish whether taurocholic acid, administered as a suppository, can stimulate secretion of the gut peptides GLP-1, PYY, and oxyntomodulin, and suppress subsequent appetite and food intake. This information could be useful in designing treatments for type 2 diabetes and obesity.
