Varying the Energy Density and Portion Size of the Main Course After a First-course Salad

The purpose of this research is to determine whether varying the energy density and portion size of the main course will affect meal energy intake after consumption of a first course that has previously been shown to enhance satiety. It is hypothesized that increasing either the energy density or portion size of the main course will increase meal energy intake after consumption of the first course. It is also hypothesized that compared to when a first course is consumed, not consuming a first course will increase meal energy intake.

Treatment and study plan

Energy density and portion size feeding study

Other

In a crossover design, adults are served breakfast and lunch, 1 day a week for 6 weeks. Breakfast is not varied across weeks. At 4 of the lunch meals, a salad first course will be served that needs to be eaten in its entirety. At these 4 meals the lunch entree will vary in energy density (100% and 133%) and portion size (100% and 133%). At the 2 lunch meals for which no first course is served, the lunch entree will be vary in energy density (100% and 133%) but be the same portion size (133%).

Primary outcomes
