INSULIN SENSITIVITY
Fifty-four healthy volunteers with a large variance in body weight (Table All participants were recruited from the preexisting database of volunteers maintained at the Max Planck Institute for Metabolism Research. Participants were medication-free non-smokers without any history of neurological, psychiatric, gastrointestinal or eating disorders and without any special diets. To assess each participant’s peripheral insulin sensitivity as a proxy for their central insulin sensitivity, we considered the HOMA-IRAll participants performed one session of an associative sensory learning task (for a detailed task description, see Iglesias et al.As a result, a total of 68 individual sessions (34 placebo sessions and 34 liraglutide sessions) from 43 different participants (23 in the insulin-sensitive group and 20 in the insulin-resistant group) were included into the analysis (see Table The final sample (All participants gave written informed consent to participate in the experiment, which was approved by the local ethics committee of the Medical Faculty of the University of Cologne (16-251).
