Influence of Visual Differences in Bowl Size and Types on Dietary Intake of Female College Students with Normal Weight / 대한지역사회영양학회지

ABSTRACT

OBJECTIVES: This study examined the impact of perceived volume on satiety using normal rice bowl, diet rice bowl and small rice bowl. METHODS: Thirty-six normal weight college female students participated in this study once a week for 3 weeks. Three hundred grams of fried rice in a normal rice bowl (1st week), 300 g of fried rice in a diet rice bowl (2nd week), and 300 g of fried rice in small rice bowl (3rd week) were served to the same participants over three consecutive weeks. After each lunch, the consumption volume of fried rice and the satiety rate were measured. RESULTS: The consumption volume of fried rice was 248 g (414.5 kcal) with a normal rice bowl, 254 g (429.8 kcal) with a diet bowl, and 270 g (456.8 kcal) with a small rice bowl. Results showed that the subjects who were eating from the small rice bowl ate more fried rice (p < 0.05) than eating from the normal rice bowl and diet rice bowl. However, the satiety rate of fried rice in a diet rice bowl was significantly higher than that of normal rice bowl and small rice bowl (p < 0.05). The five point scale of perceived volume on fried rice served normal rice bowl, diet rice bowl and small rice bowl were 2.4, 4.0 and 2.1. CONCLUSIONS: The visual cue plays a critical role in determining satiety and that perceived volume is perhaps more important than actual volume of consumed food in determining the level of fullness.
