The control of meal size in human subjects: a role for expected satiety, expected satiation and premeal planning
Brunstrom's review challenges the standard account of how much people eat. That account holds that meal size is settled during the meal, by the physiological and psychological processes that produce fullness. His alternative is that these play a secondary role, and that the decision is mostly made before eating begins, when a portion is chosen. The evidence comes from measuring what he calls expected satiation and expected satiety, how filling a food is anticipated to be and how long it is expected to hold hunger off. Compared calorie for calorie, foods differ enormously in these expectations. When people serve themselves, those expectations predict the energy content of what ends up on the plate better than how much they like the food does. Expectations are shaped partly by a food's appearance and volume, and partly by learning: familiarity with a food raises its expected satiation over time. Since most meals are eaten in full, he argues the decisive control lies in planning rather than in stopping.
