About

A pilot study was conducted to develop the study menus that were similar in appearance, aroma, and taste.

Full description

The aim of the pilot study was to test for differences in palatability ratings of the four menus that will be administered during the ENERGY I project. During the pilot study, palatability ratings were collected for each meal (breakfast, lunch, and dinner) from four different menus that were served to participants during the main ENERGY I trial. The menus consist of three diets that vary in dietary fat and energy density: 1) high fat/high energy density, 2) high fat/low energy density, and 3) high carbohydrate/low energy density. In addition to these three menus, the menu from the baseline period of the trial will also be tested for palatability.
