Effect of Energy Density on Liking and on Caloric Adjustment Conditioning

Study Overview
=================
Brief Summary
-----------------
The main objective is to study, in 8-11 year old children, the influence of energy density conditioning on liking for new flavored beverages and on caloric adjustment after the beverage consumption. The stability of the energy conditioning was evaluated after a period without exposure and after an extinction period during which the energy density of the beverages was changed.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: 2 exposures<br>During the conditioning period, the children of this group was exposed only twice to the beverages | Behavioral: 2 exposures arm<br>* During this study, children were exposed to 2 flavored sweetened beverages: a high energy version (HE: 150kcal) and a no energy version (NE: 0kcal). During a 4-wk conditioning period, children were exposed either 2 times to each beverage. After a 3-wk stability period without exposure, children were exposed 3 times to both beverages in which the association between the flavor and the energy density had been switched (4-wk extinction period).<br>|
