GIP and Obesity: The aims of this study were: i) to evaluate the cross-sectional associations between plasma GIP change in response to an oral glucose challenge (as a surrogate of GIP secretion) with obesity-related anthropometric measurements, fasting inflammatory biomarkers, and fasting circulating adipokines; and ii) to evaluate the feasibility of using postprandial plasma GIP as a biomarker of adiposity-related phenotypes in response to starch-based meals.
