Plasma GLP-1, glucagon and leptin in rats during an oral glucose tolerance test following a high fat/sucrose diet challenge. Results are presented as mean ± SE, n = 8-9 per group. No sex effect was detected for GLP-1, glucagon and leptin, therefore male and female data were combined. Panel A provides the serial values of plasma GLP-1 during the OGTT. In Panel A, the * represents a difference (p < 0.05) between HF and HP at the indicated time points. Panel B provides the serial values of plasma glucagon. Panel C provides the serial values of leptin. In Panel C, the * represents a difference (p < 0.05) between HP versus HF and C. The † represents a difference (p < 0.05) between HP and HF at 15 minutes.
