Mechanisms underlying the portion-size effect.
The portion-size effect (PSE) refers to the fact that people eat more when served larger portions. This effect is neither obvious nor artifactual. We examine the prevailing explanations (or underlying mechanisms) that have been offered for the PSE. The dominant candidate mechanism is "appropriateness"; that is, people accept the portion that they are served as being of an appropriate size and e...
متن کاملThe effect of portion size and unit size on food intake: Unit bias or segmentation effect?
OBJECTIVE The "unit bias" has been proposed as an explanation for the portion-size effect; people consider a single unit to be an appropriate amount to eat and thus eat more when served a larger unit than when served a smaller unit. We suggest that the unit bias might be better characterized as a "segmentation effect," such that people eat less when a unit of food is separated into smaller subu...
متن کاملThe mathematical relationship between dishware size and portion size.
Portion size has increased considerably over the past few decades and one influencing factor is dishware size. Using mathematical models we investigated how dish size affects the potential energy available in a meal. Two types of plate filling - flat and conical - were modelled for a range of plate sizes and energy densities, then compared to recommended daily energy requirements from Australia...
متن کاملThe portion size effect on food intake is robust to contextual size information.
Larger portion sizes have consistently been shown to lead to greater food intake. However, studies of the portion size effect typically provided participants with a single portion of food at a time without any objective information about the size of the portion, and hence failed to consider the potential significance of contextual size information. In order to investigate whether contextual siz...
متن کاملCan serving-size labels reduce the portion-size effect? A pilot study.
Research has shown that the bigger the portion that people are served, the more food they eat; this phenomenon is referred to as the portion-size effect. Providing objective serving-size information on food products has been shown to reduce the influence of external food cues on people's eating behavior. The current study examined whether providing objective serving-size information would also ...
