While Food reward is an important component of the appetite control to consider, there is actually no tool that has been developed in French to perform its evaluation. The Leeds Food Preference Questionnaire (LFPQ) is a validated and recognized tool to assess food reward, being however developed for British populations. The aim of this work is to validate a French version of the LFPQ among lean and obese adults.
50 lean and 50 patients with obesity between 20 and 55 years old (50% women and 50% men), will be recruited. After an evaluation of their body composition by impedance meter, and of their dietary status by questionnaires (TFEQ/DEBQ), they will be asked to perform twice the same experimental sessions. They will be asked during this session to arrive at 08:00 am after a 12-hour fast and will receive a calibrated breakfast. Before and after a lunch calibrated meal, they will be asked to perform the French version of the computerized questionnaire LFPQ. Appetite feelings will be assessed at regular intervals.
