PENAFORTE, Fernanda R.O.; JAPUR, Camila C.; DIEZ-GARCIA, Rosa W.  and  CHIARELLO, Paula G.. Effects of a high-fat meal on postprandial incretin responses, appetite scores and ad libitum energy intake in women with obesity. Nutr. Hosp. [online]. 2017, vol.34, n.2, pp.376-382. ISSN 1699-5198.


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).


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.


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.


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.
