To evaluate the change in caloric compensation across time, caloric compensation was measured at baseline, 3 and 15 months after baseline, in the same conditions. At each time point to assess caloric compensation, children were offered a chocolate bun 30 minutes before the lunch. The food intake at lunch was recorded. We calculated if children compensated the chocolate bun, by comparing energy intake at this lunch with energy intake from a control lunch which took place one week before.

We conducted a control lunch and recorded food intake of each child. This measurement was conducted a week before measuring caloric compensation.

In order to evaluate the change in eating in the absence of hunger across time, a measurement was conducted at baseline, 3 months and 15 months after baseline. To collect the measurement of eating in the absence of hunger, we offered palatable foods to children 10 minutes after their lunch. We recorded the energy intake from these post-meal foods. At each time point, this measurement was conducted one week after the measurement of caloric compensation.

We conducted a control lunch and recorded food intake of each child. This measurement was conducted a week before measuring caloric compensation.

Using a validated questionnaire, we collected information about maternal feeding practices (Comprehensive Feeding Practices Questionnaire, Musher-Eizenman & Holub, 2007) and eating behaviour (Dutch Eating Behaviour Questionnaire, Van Strien, 1986).
