Reductions in food energy density can decrease energy intake, but it is not known if the effects depend on the way that energy density is reduced. We investigated whether three methods of reducing energy density (decreasing fat, increasing fruit and vegetables, and adding water) differed in their effects on energy intake across the day. In a crossover design, 59 adults ate breakfast, lunch, and dinner...
Portion size has increased considerably over the past few decades and one influencing factor is dishware size. Using mathematical models we investigated how dish size affects the potential energy available in a meal. Two types of plate filling – flat and conical – were modelled for a range of plate sizes and energy densities, then compared to recommended daily energy requirements from Australian guidelines...
Increased reports of restrictive feeding have shown positive relationships to child obesity, however, the mechanism between the two has not been elucidated. This study examined the relationship between reported use of restrictive feeding practices and 4–6-year-old children's self-selected energy density (ED) and total energy intake from an ad libitum, laboratory dinner including macaroni and cheese,...
Much of the research in ingestive behavior has focused on the macronutrient composition of foods; however, these studies are incomplete, or could be misleading, if they do not consider the energy density (ED) of the diet under investigation. Lowering the ED (kcal/g) by increasing the volume of preloads without changing macronutrient content can enhance satiety and reduce subsequent energy intake at...
Rats that are fed cafeteria diet (CD) are a widely used model of obesity. Presenting a varied and energy-dense diet often leads to hyperphagia and weight gain. However, the exact macronutrient composition of ingested food remains difficult to measure accurately. The current investigation aims to improve the accuracy of food intake calculations using a novel compensation for water evaporation, and...
