Food cue paradigm
HED
During the food cue reactivity task, four categories of colour images were presented in a single run using a block design: (1) very low‐ and low‐energy density foods (LED; Stimuli were presented in eight blocks each containing five images from the LED, HED and non‐food object categories, which were interspersed with 16 blocks each comprised of five scrambled images (Figure Participants viewed the stimulus via a mirror attached to the head coil on a MR‐compatible monitor at the head of the scanner. Visual stimulus presentation and synchronization to fMRI acquisition was controlled using the software package Presentation® version 21.1 (Neurobehavioral Systems, Inc., California, USA). Images were marginally offset from the centre of the screen and participants used a hand‐held button box connected to a Lumina LSC‐400 controller (Cedrus Corporation, California, USA) to indicate left or right position to ensure they were attentive during the task. At the end of the study, food images were rated for familiarity, consumption and liking, and object images were rated for familiarity, using an online survey (supplementary results, Section
