Effects of sensory stimulation and post-ingestive consequences on satiation

This study investigated the influence of sensory stimulation, with and with out post-ingestive consequences, on satiation by varying the form of a prel oad and the timing of a mixed meal presented after the preload. Twenty-four , normal-weight, non-dieting, college-aged women were randomized to differe nt preload groups: water preload (Water), sip-and-spit energy-dense preload (Taste), or energy-dense preload (Taste/kcal). Volume of fluid consumed pr ior to the meal was controlled. Ail participants had sessions in which a me al was provided immediately (0 min) or 30 min after the preload. Results sh owed equal suppression of intake for participants receiving sensory stimula tion from an energy-dense preload (Taste and Taste/kcal groups) in comparis on to a water preload (Water group). No effect of time from preload to food consumption was found; the suppression of intake was similar whether the m eal immediately followed the preload or was 30 min after the preload. These findings suggest that sensory aspects of food can influence satiation, and in the conditions of this study, had a larger influence on satiation than post-ingestive consequences.
