- It was examined whether altering vision would influence food intake through consumption monitoring and whether this would be reflected in consumption estimate and satiety. The experiment was designed in two visibility levels: 1) an accurate visual cue (bowl covered with wrap) vs 2) a biased visual cue (bowl covered with foil). Thirty three female college students participated in this study. The subjects ate Kimbab in the lab once a week for 2 weeks. They were served 24 pieces of Kimbab in a bowl covered either with wrap or foil. The results showed that the actual Kimbab intake from the bowl covered with foil was significantly lower than the test using wrap (13.4 +/- 3.3 pieces vs 15.0 +/- 3.8 pieces, p < 0.05). And there were no significant differences from the cognitive Kimbab intake between the tests with foil and wrap. However, the satiety rate of Kimbab in a bowl covered with foil was significantly higher than that with wrap at 1 hour and 2 hour after the Kimbab eaten (p < 0.05). Less consumed cases were recognized by subjects due to the inaccuracy during the consumption monitoring process. This result revealed that vision influences not only eating behavior but also subjective feelings of satiety after meal. In conclusion, the consumption monitoring by visual cues can play an important role in food intake and satiety rate.

- Using the diet rice bowl, this study examined whether visual cues related to portion size can influence intake volume without altering satiation. 24 subjects ate lunch and subsequent dinner meal in the lab once a week for 2 weeks. Each week at noon , they were served one of two different sizes of a rice (150 g of rice by the diet rice bowl and 210 g of rice by the general rice bowl) but recognized the same volume of which they could eat as much as they wanted of side dishes. Subjects returned to the lab five hours later for a standard dinner, which was consumed ad libitum. Results showed that the subjects who were eating from the diet rice bowl ate less rice (222.4 Kcal vs 306.5 Kcal, p < 0.001) and total energy intake (412.5 Kcal vs 499.2 Kcal, p < 0.001) than those eating from a general rice bowl at lunch. However, despite consuming 21% less energy intake at lunch, the rates of satiety were not significantly different after eating from the diet rice bowl and from the general diet bowl. And there were no significant difference in rice intake and energy intake at dinner between the diet rice bowl and the general rice bowl. These results suggest decreasing the portion size by the diet rice bowl with biased visual cues leads to decreased rice intake and energy intake without altering the satiation. This is, the decreased amount of rice in a diet rice bowl may implicitly suggest what might be construed as an appropriate amount to consume and eventually it suggests smaller consumption norms.
