It is closely associated with 'expected satiation' which refers to the immediate fullness (post meal) that a food is expected to generate. Scientists have discovered that foods differ considerably in their expected satiety. One estimate suggests that there may be a six-fold difference in commonly consumed foods (in the UK), when they are compared calorie for calorie. This range of variation is important because expected satiety is thought to be a good predictor of food choice and an excellent predictor of self-selected portion sizes. Specifically, foods that have high expected satiety and high expected satiation tend to be selected in smaller portions (fewer calories). Therefore, they may be especially suited to diets that are designed to reduce energy intake. Some researchers also suggest that expected satiety is an important mediator of energy intake. They argue that within-meal events (immediate post-ingestive feedback, e.g., gastric stretch) play a relatively minor role and that meal size is largely determined by decisions about portion size, before a meal begins. Consistent with this proposition, observational studies show that 'plate cleaning' is extremely common, that humans tend to plan their meal size in advance, and that ''ad libitum'' eating is relatively rare. ==Measurement== Early approaches relied on rating scales. More recently, techniques have been developed that quantify expectations very precisely by comparing foods directly on a calorie-for-calorie basis. The first of these used a classical psychophysical approach based on a 'method of constant stimuli'. Participants are shown a fixed 'standard' portion of food and this is compared against a different 'comparison' food. Over a series of trials the size of the comparison food is manipulated and participants are asked to pick the food that is expected to deliver greater satiety. At the end of the task a measure of 'expected satiety' is calculated. This relates to the number of calories of the comparison food that would be expected to deliver the same satiety as the fixed standard. A conceptually similar alternative is to use a 'method of adjustment'. Participants are shown a picture of a standard food next to a picture of a comparison food. Using specialist software, participants change the size of the comparison portion using keyboard responses. Pictures are loaded with sufficient speed that the change in the comparison becomes 'animated.' Participants are told to match the comparison food until both are expected to deliver the same satiety. If the same standard is used then the expected satiety of different foods can be quantified and compared directly. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Expected satiety」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
