Food wanting task and behavioural data. (a,b) Food wanting task: Participants indicated in a two-step procedure how much they wanted to eat the displayed food at the moment. The wanting (a) or rejection (b) of an item was followed by 4-point rating scale ranging from weakest wanting (+) or rejection (−) to strongest wanting (++++) or rejection (− − − −). Answers selected by the participant were highlighted in green in order to provide visual feedback (c/e) Behavioural data: Results from the two-step ratings were combined to a 8-point food wanting score (see text for details). Mean values across items for each participant are depicted in (c). Within subject correlation between the item-wise combined wanting rating and sugar (fat) content are shown for each participant (see text for details) in (d). Every point refers to the result/data of one participant; the black line represents the mean across all participants. BMInorm: BMI: 18.5–24.9 kg/m², N = 23; BMIover: BMI ≥ 25 kg/m², BMIover, N = 22.
