Reducing Energy Density by Different Methods to Decrease Energy Intake

November 10, 2011 updated by: Barbara J. Rolls, Penn State University
The purpose of this research is to investigate how using different methods to reduce the energy density of entrees affects daily energy intake in adults. It is hypothesized that reducing the energy density of entrees will decrease energy intake. It is also hypothesized that reducing the energy density by incorporating fruit and vegetables will decrease energy intake more than reducing the energy density by decreasing fat content or adding plain water.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
EXPERIMENTAL: Standard ED
100% energy density
Other: Energy density feeding study
In a crossover design, adults are served breakfast, lunch, and dinner, 1 day a week for 4 weeks. Meal entrees will vary in energy density (100% and 80%) and the method used to reduce the energy density (added fruit & vegetables, decreased fat, added plain water).
EXPERIMENTAL: Reduced ED - F/V
80% energy density by adding fruit and vegetables
Other: Energy density feeding study
In a crossover design, adults are served breakfast, lunch, and dinner, 1 day a week for 4 weeks. Meal entrees will vary in energy density (100% and 80%) and the method used to reduce the energy density (added fruit & vegetables, decreased fat, added plain water).
EXPERIMENTAL: Reduced ED - Fat
80% energy density by decreasing fat
Other: Energy density feeding study
In a crossover design, adults are served breakfast, lunch, and dinner, 1 day a week for 4 weeks. Meal entrees will vary in energy density (100% and 80%) and the method used to reduce the energy density (added fruit & vegetables, decreased fat, added plain water).
