Background:
Considering the possible role of triglycerides (TG), glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) in the regulation of appetite, this study aimed to compare high fat meal-induced response of GIP and GLP-1, appetite scores and ad libitum energy intake in women with obesity, according to postprandial increment in triglyceridemia (∆TG).
Methods:
Thirty-three no-diabetic women (BMI = 35.0 ± 3.2 kg.m-2) were divided into two groups: Group with ∆TG ≤ median were called "Low TG change -LTG" and ∆TG > median, "High TG change - HTG". Plasma concentrations of GIP, GLP-1 and appetite sensations were measured prior to, and every 30 min for 180 min after ingestion of a high-fat breakfast. An ad libitum lunch was served 3 h after the test meal.
Results:
The AUC incrementalGIP were significant lower in HTG vs. LTG group (p = 0.03). The same was observed for GIP levels at 150 min (p = 0.03) and at 180 min (p < 0.01). Satiety was lower in HTG at 120 min (p = 0.03) and 150 min (p < 0.01). The AUC totalGLP1 were similar between groups and there were no between-group differences for the GLP-1 at each time point. Ad libitum food intake were also similar between groups.
Conclusions:
The HTG group exhibited differences in satiety scores and lower postprandial secretion of GIP, however with no impact on ad libitum food intake in short term.
