Brief summary: The Leeds Food Preference Questionnaire (LFPQ) is a computer-based task used to measure reward responses and preferences for images of food. The present study aims to develop a Spanish version of the LFPQ (ES-LFPQ) by examining its validity and repeatability under fasted and fed states.

Detailed description: The Leeds Food Preference Questionnaire (LFPQ) is a computer-based task for measuring reward responses (liking/wanting) and preferences for images of food. There are no cultural adaptation studies for the Spanish population to date in order to address its validity and repeatability in a test-retest design. The present study aim to develop a Spanish version of the LFPQ (ES-LFPQ), examine its outcomes under fasted and fed states; and test its reproducibility after one week.

An online survey containing foods that were either low-fat sweet, high-fat sweet, low-fat savoury or high-fat savoury was first conducted among a sample of 96 Spanish adults (60.4 % women) to develop and validate a culturally appropriate food image database. 50 participants (25 men and 25 women) will participate in two identical trials where they will completed the ES-LFPQ under fasted and fed states (immediately after a standardised meal), at least one week apart.

Eligibility criteria: Inclusion Criteria:

* Being able to understand instructions, programs and questionnaires.
* Being able to recognize the foods presented in at least 4 of the 5 photographs available for each category that make up the ES-LFPQ.
* Living in Spain for at least 2 years

Exclusion Criteria:

* Being intolerant, allergic and/or having an aversion to the foods contained in the standardized meal.
* Never eat the foods presented in at least 4 of the 5 photographs available for each category that make up the ES-LFPQ
