An interventional study of Visit 1 and Visit 2 in Normal Weight Adults and Adults With Obesity, sponsored by University Hospital, Clermont-Ferrand. Terminated at 1 site in France. Open to participants aged 20 Years to 55 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-08-07.

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.
University Hospital, Clermont-Ferrand is the lead sponsor of 841 studies on the registry; 178 are open to participants now.
Counted across the registry records on this site, refreshed daily.
Exclusion Criteria:
20 to 55 years old lean adults
Behavioral: Visit 1 · Behavioral: Visit 2
20 to 55 years old adults with obesity
Behavioral: Visit 1 · Behavioral: Visit 2
the participants will fill in the LFPQ questionnaire before and after a lunch test meal
this is a replication of Visit 1, testing the reproducibility of the LFPQ and of its response to a meal.
