Effect of Energy Density on Liking and on Caloric Adjustment Conditioning

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.

Treatment and study plan

2 exposures arm

Behavioral

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).

7 exposures arm

Behavioral

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 7 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).

Primary outcomes

  1. Flavored beverages liking and preference before the conditioning period (T0)

    Time frame: Baseline

    Liking and preference measurements for the flavored beverages, before the conditioning period.

Secondary outcomes

  1. Energy adjustment before the conditioning period (T0)

    Time frame: Baseline

    Measure of energy intake at the lunch following the beverage consumption, before the conditioning period

Other outcomes

  1. Energy adjustment after the conditioning period (T1)

    Time frame: T0 + 4 weeks

    Measure of energy intake at the lunch following the beverage consumption, after the 4-week conditioning period

  2. Flavored beverages liking and preference after the conditioning period (T1)

    Time frame: T0 + 4 weeks

    Liking and preference measurements for the new flavored beverages, after the 4-week conditioning period.

  3. Flavored beverages liking and preference after 3 weeks without exposure (T2)

    Time frame: T1 + 3 weeks

    liking and preference measurements of the new flavored beverages, after a period of 3 weeks without exposure (=stability period)

  4. Flavored beverages liking and preference before the extinction period (T3)

    Time frame: T2 +1 week

    Liking and preference measurements of the new flavored beverages before a 4-week- extinction period during which the energy density of the beverages were changed

  5. Energy adjustment before an extinction period (T3)

    Time frame: T2 + 1 week

    Measure of energy intake at the lunch following the beverages consumption,before the 4-week- extinction period, during which the energy density of the beverages were changed.

  6. Energy adjustment after 3 weeks without exposure (T2)

    Time frame: T1 + 3 weeks

    Measure of energy intake at lunch following the beverage consumption, after a period of 3 weeks without exposure

  7. Energy adjustment after the extinction period (T4)

    Time frame: T3 + 4 weeks

    Measure of energy intake at the lunch following the beverages consumption,after the 4-week- extinction period, during which the energy density of the beverages were changed.

  8. Flavored beverages liking and preference before the extinction period (T4)

    Time frame: T3 + 4 weeks

    Liking and preference measurements of the new flavored beverages after the 4-week- extinction period during which the energy density of the beverages were changed
