Brief Summary
The portion size of foods has been identified as an important determinant of energy intake in children. It remains to be determined to what extent child weight status and the relative reinforcing value of food may interact with the obesogenic food environment to affect energy intake. The primary aim of this study was to compare energy intake at a meal in normal-weight and obese children when the portion size of palatable, energy-dense foods and a sugar-sweetened beverage was systematically increased. We hypothesized that increasing the portion size of all foods and the beverage at a meal will lead to a significant increase in energy intake in both normal-weight and obese children. Obese children, however, will show a significantly greater increase in energy intake than will normal-weight children. A second aim of this study was to test if children's response to increases in portion size was affected by how reinforcing they find food to be. We hypothesized that, when controlling for BMI, children who find food very reinforcing relative to nonfood alternatives will show a significantly greater increase in energy intake than will children who find food less reinforcing.
