Research to be presented at the Annual Meeting of the Society for the Study of Ingestive Behavior (SSIB), the foremost society for research into all aspects of eating and drinking behavior, suggests that the key to losing weight could lie in manipulating our beliefs about how filling we think food will be before we eat it, suggesting that portion control is all a matter of perception. Test subjects were more satisfied for longer periods of time after consuming varying quantities of food for which they were led to believe that portion sizes were larger than they actually were. Memories about how satisfying previous meals were also played a causal role in determining how long those meals staved off hunger. Together, these results suggest that expectations before eating and memory after eating play an important role in governing appetite and satiety.
