My PhD project aimed at developing an edible product for non-invasive weight management, and targeted a natural feedback mechanism to induce satiety: the ileal brake. In order to trigger the ileal brake mechanism, lipids and their non-absorbed metabolites need to be sensed in the ileum. We aimed at inducing this mechanism through targeted release of lipids after oral intake, for which we developed multi-layered emulsions and emulsion-alginate beads. We showed that emulsion-alginate beads control in vitro lipolysis as a function of bead size and alginate concentration, and confirmed these findings under dynamic in vitro gastrointestinal conditions (DIDGI). Moreover, ingestion of yoghurt with emulsion-alginate beads significantly reduced food intake by 6% in overweight volunteers compared to a control group, suggesting that activation of the ileal brake was achieved. These findings have important implications for the development of weight management strategies, and understanding satiety in general.
