Abstract

There is mounting evidence that oral processing behaviours can have a marked effect on energy intake in humans. For example, under controlled conditions, eating at a slower rate is found to promote self-reported fullness and to reduce energy intake. Moreover, significant and lasting (12 months post-treatment) reductions in BMI have been reported when obese children are trained to moderate their rate of eating using a “mandometer.” To understand these relationships, we have developed a measure of “eating topography” (e.g., eating rate, inter-bite interval, and bite size). Our objective is to identify specific aspects of eating topography that might be modified in order to achieve a sustained reduction in energy intake. Using a within-subjects design, female participants attended the laboratory over 20 lunchtime sessions. In each session they consumed a 400-kcal portion of a different meal. Prior to consumption, expected satiation was assessed. During each meal, eating topography was characterised using; (i) video-recordings of the mouth, and (ii) real-time measures of plate weight. Hunger and fullness ratings were elicited pre- and post-consumption. Our results show that the test meals have their own eating topography “signature”. Moreover, eating rate correlates significantly with expected satiation. Together, these findings suggest that effects of eating topography on satiation are learned and expressed in decisions about portion size. This research was supported by a BBSRC-LINK grant (ref: BB/J005622/1).
