Brief summary

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.

Interventions

OTHEREnergy 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).
