“…Several studies suggest that liquids consumed as beverages are less satiating than solid foods (Bolton, Heaton, & Burroughs, 1981;Dimeglio & Mattes, 2000;Haber, Heaton, Murphy, & Burroughs, 1977), while other studies have found that liquids in the form of soup can be more satiating than solid foods (Kissileff, Gruss, Thornton, & Jordan, 1984;Rolls, Fedoroff, Guthrie, & Laster, 1990a). Several studies have found that eating soup as a preload can decrease hunger, increase fullness, and reduce subsequent test meal intake (Himaya & Louis-Sylvestre, 1998;Kissileff, Gruss, Thornton, & Jordan, 1984;Rolls, Bell, & Thorwart, 1999;Rolls, Fedoroff, Guthrie, & Laster, 1990). However, while it has become clear that consuming soup before a meal can reduce subsequent food intake, few studies have been designed to test whether consuming soup as a preload may help reduce total energy intake (soup + test meal) at the meal.…”
