ABSTRACT
Large portion sizes of palatable, energy-dense foods were first suggested to be a part of the obesogenic food environment almost two decades ago [1]. Today’s children and adults have ubiquitous exposure to large food and beverage portion sizes in the marketplace, from large single-serving containers and family-value multiple-serving containers found in grocery and convenience stores to food and beverage offerings at fast-food and full-service restaurants [2,3]. The appeal of large food portions to consumers, including families with young children, is enhanced by aggressive marketing efforts for foods high in sugar and fat, as well as by pricing incentives for the purchase of larger portion sizes (i.e., value pricing) [4].
