Increased caloric beverage consumption, especially between meals, may lead to weight gain. Therefore, beverages that increase satiety and decrease meal intake may be an effective weight management tool. The purpose of this study was to determine whether consuming orange juice, orange juice with added fiber (wheat dextrin), or 1% milk 30 minutes prior to a meal affects subjective measurements of satiety, hunger, and fullness, and to assess if there was a difference in subsequent energy intake. It was hypothesized that consuming a beverage containing fiber before a meal would significantly decrease feelings of hunger and reduce energy intake compared to a control no beverage preload. Twenty-five college students participated; each subject attended four test meals. After consuming the beverages, the subjects waited for 30 minutes and were given a visual analog scale to rate their hunger, satiety, and fullness. The test meal (oatmeal) was weighed before and after consumption to determine energy intake. The orange juice with added fiber significantly (p ? 0.05) reduced feelings of hunger, increased fullness, and increased satiety compared to no beverage. The amount of oatmeal consumed was not significantly different among the four treatments. Further research is needed to determine if a larger dose of wheat dextrin added to a beverage consumed prior to a meal decreases overall energy intake.
