ABSTRACT Examine the influence of altering the size of snack food (ie, small vs large cookies) on short-term energy intake.
First- and sixth-graders (n = 77) participated in a between-subjects experimental design. All participants were offered the same gram weight of cookies during an afternoon tea at their school. For half of the participants, food was cut in 2 to make the small item size. Food intake (number of cookies, gram weight, and energy intake) was examined using ANOVA.
Decreasing the item size of food led to a decrease of 25% in gram weight intake, corresponding to 68 kcal. Appetitive ratings and subject and food characteristics had no moderating effect.
Reducing the item size of food could prove a useful dietary prevention strategy based on decreased consumption, aimed at countering obesity-promoting eating behaviors favored by the easy availability of large food portions.

    ABSTRACT: People consistently over-eat when served a large compared to a small (appropriate) portion of food. However, the mechanism underlying this so-called portion size effect is not well understood. We argue that the process of anchoring and adjustment naturally describes this effect, such that the size of a presented portion works as an anchor that strongly influences consumption. The classical anchoring and adjustment paradigm was applied to six hypothetical eating situations. Participants were asked to imagine being served either a small or a large portion of food (i.e., low and high anchor) and to indicate whether they would consume more or less than this amount. Then, they indicated how much they would eat. These estimates were compared to a no-anchor condition where participants did not imagine a specific portion size but only indicated how much they would eat. In addition, half of participants in the anchoring conditions received a discounting instruction stating that the portion size they had been asked to imagine was randomly selected and thus not informative for their consumption estimate. As expected, participants who imagined to be served larger portions estimated to consume significantly more food than participants in the no-anchor condition, and participants who imagined to be served smaller portions estimated to consume significantly less food than participants in the no-anchor condition. The discounting manipulation did not reduce this effect of the anchors. We suggest that the process of anchoring and adjustment may provide a useful framework to understand the portion size effect and we discuss implications of this perspective.

    ABSTRACT: Abstract In deciding how much to eat, people are influenced by environmental cues. The unit size of food (i.e. the number of units in which a given amount of food is divided) provides such a cue. Previous research showed that given equal caloric and volumetric content, smaller units of food tend to reduce food consumption. We propose that the unit size of food impacts intake as it influences perceptions of impulsiveness and appropriateness. Our analysis is based on three experimental studies, all employing between subject designs. When consuming similar amounts of chocolates in study 1 (n=118) and 2 (n=124), both studies show that consumption of five small units of chocolates is considered to be more impulsive, excessive and less appropriate than consuming one large unit of chocolate. Results of a third study (n=165) indicate that about 23% less chocolate is eaten when it is presented in small unit size versus a large unit size and this effect is mediated by perceptions of impulsivity. All three studies suggest that perceptions of impulsivity and excess eating while eating several smaller units of food compared to one large unit might be a key factor explaining consumption effects in earlier studies on this bias.
