研究概览
简要总结
The purpose of the study is to explore the effects of GLP-1 receptor agonist (GLP-1 RA) semaglutide on modulation of taste sensitivity, tongue tissue transcriptome, modulation of neural response in central reward processing regions and gastric emptying rate. In addition, we aim to investigate the associations between semaglutide induced modulation of taste sensitivity, neural responses and gastric emptying with changes in body mass, eating- behavioural pattern, food perception and food intake.
