Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Participants

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Pilot Group 1

Each Participant completed taste tests at breakfast, lunch and dinner consisting of the 4 menus (baseline, high fat-high energy density, high fat-low energy density, and high carbohydrate-low energy density).

Group Type EXPERIMENTAL

Breakfast (1-2 hours, in the morning)

Intervention Type OTHER

You will be required to taste small portions (1 to 2 bites) of 4 different breakfast meals. You will be asked to reate the taste after each meal. Meals will vary in fat and energy density, and will consist of two high fat diets and a high carbohydrate diet. Energy density is the ammount of enregy of kilocalories in one gram of the food.

Lunch (1-2 Hours, at midday)

Intervention Type OTHER

You will be required to taste small portions of 4 different lunch meals. You will be asked to reate the taste after each meal. Meals will vary in fat and energy density, and will consist of two high fat diets and a high carbohydrate diet. Energy densityis the ammount of enregy of kilocalories in one gram of the food.

Dinner (1-2 hours, in the afternoon)

Intervention Type OTHER

You will be required to taste small portions of 4 different dinner meals. You will be asked to reate the taste after each meal. Meals will vary in fat and energy density, and will consist of two high fat diets and a high carbohydrate diet. Energy densityis the ammount of enregy of kilocalories in one gram of the food.

Pilot Group 2

Each Participant completed taste tests at breakfast, lunch and dinner consisting of the 4 menus (baseline, high fat-high energy density, high fat-low energy density, and high carbohydrate-low energy density).

Group Type EXPERIMENTAL
