Brief summary
The objective of this study is to examine ghrelin, amylin, glucagon and glucagon-like peptide (GLP)-1 responses to a test meal in lean and obese individuals.
Detailed description
The primary hypothesis is that obese adolescents have a disturbed balance of hormones associated with appetite regulation with less suppression of ghrelin and attenuated stimulation of GLP-1 secretion in response to meal intake compared to lean normal weight controls. A second aim of the study was to test which gastrointestinal peptides are most associated with insulin resistance.
Interventions
