“…A self-served portions experiment revealed that only 45% of portions at breakfast and 32% of portions at lunch or dinner were either 25% bigger or 25% smaller that the recommended portion size, with a majority of those portions being bigger (Schwartz & Byrd-Bredbenner, 2006). People who serve themselves bigger portions or who are served bigger portions tend to consume more (Diliberti, Bordi, Conklin, Roe, & Rolls, 2004; Levitsky & Youn, 2004; Raynor & Wing, 2007; Rolls, Morris, & Roe, 2002; Rolls, Roe, Kral, Meengs, & Wall, 2004) and food choice is important when determining the preferences (Zampollo, Kniffin, Wansink, & Shimizu, 2012) and number of foods available at a meal (Levitsky, Iyer, & Pacanowski, 2012). …”
