Intervention
Outcome measures
Primary outcome
To assess whether the fat droplet size in an emulsion affects satiety (as measured by visual analogue scales) and food intake (during ad libitum lunch) when infused into the duodenum and when infused into the ileum.
Secondary outcome
To assess whether the fat droplet size in an emulsion affects gastric emptying, intestinal transit time and secretion of peptides known to affect satiety (CCK, PYY) when infused into the duodenum and when infused into the ileum.
Study objective
Long-chain triglyceride (LCT) emulsions with very small droplet sizes (fine emulsion) will lead to enhanced postprandial satiety and reduced energy intake in a subsequent meal, as compared to LCT emulsions with relatively large droplet sizes (coarse emulsion). Infusion in the ileum will enlarge this effect as compared to the duodenum.
