Summary

In the present study the investigators will investigate the effect of consuming lipids inside alginate gel once a day during 4 days on food intake and satiety feelings in healthy people with overweight. All participants will receive a test yogurt that includes the oil-filled Ca-alginate gels and a control yogurt where the oil is not inside the gels.

Detailed description

Direct infusion of lipids into different parts of the human small intestine has demonstrated to decrease food intake and subjective appetite feelings, to increase production of the satiety hormones glucagon-like peptide 1 (GLP-1), peptide YY (PYY), and cholecystokinin (CCK), and diminishes gastrointestinal (GI) motility. Amongst oils with different degree of fatty acid saturation, safflower oil (high in linoleic acid, C18:2) was found the strongest inducer of the ileal brake. When ingested orally, however, the major part of dietary lipids will be digested and absorbed in the proximal small intestine and are not likely to induce the ileal brake mechanism. Incorporating small lipid droplets into millimeter-sized calcium (Ca)-alginate gel particles has shown promising results for ileal brake activation. Oral intake of these lipid containing gels have proven to reduce food intake in humans without inducing gastrointestinal symptoms. Contrastingly, to date little is known about repetitive activation of mechanisms of satiety and the effect on food intake. It is not known whether repetitive ileal brake activation provides a stronger brake or whether this will lead to a blunted response and adaptation.
