Figure 2. Behavioural results in the placebo condition.

(a) Groups means and s.e.m. of percentage of liked food and non-food items during placebo demonstrate reduced food value scores in IR. (b) Group means and s.e.m. of combined preference values ranging from 1 (‘not at all’) to 8 (‘very much’). The dashed line separates ‘yes’ from ‘no’ decisions. (c) Correlation between individual post-scan plasma insulin levels and preference values for food items during placebo. Only in NIR plasma insulin predicted preference values.
