Improved knowledge of the relationship between the form of fat in a meal, the way the meal is handled by the body and the resulting sense of satiety is critical to understanding why modern processed foods are associated with increased obesity. This work aims to determine the effect of emulsion microstructure on the handling of fat by the GI tract, using model fat emulsion meals with different droplet sizes, MRI & MRS. Both stable forms of the emulsions (coarse+LBG & fine+LBG) lead to delayed gastric emptying due to increased sense of fullness and increased SBWC due to increased fat.
