1914-P: A Plant-Based Meal Increases Gastrointestinal Hormones and Satiety More Than an Energy- and Macronutrient-Matched Standard Meal in T2D, Obese, and Healthy Participants: A Three-Group Randomized Crossover Study
2019
Objective: Gastrointestinal hormones play a key role in glucose metabolism and satiety. We examined the acute effect of meal composition on these hormones in three population groups. Research Design and Methods: A randomized crossover design was used to test the effects of two energy- and macronutrient-matched meals: a processed-meat (M-meal) and a vegan (V-meal) on gastrointestinal hormones, and satiety in participants with type 2 diabetes (T2D, n=20), obese participants (O, n=20), and healthy controls (H, n=20). Plasma concentrations of glucagon-like peptide -1 (GLP-1), amylin, and peptide YY (PYY) were determined at 0, 30, 60, 120 and 180 minutes. Satiety was assessed using a visual analogue scale. Repeated-measures ANOVA was used for statistical analysis. Results: An increase in postprandial secretion of GLP-1 was observed after the V-meal in T2D (by 30.5%; 95% CI 21.2 to 40.7%; p Conclusions: Our results indicate there is an increase in gut hormones and satiety, following consumption of a single plant-based meal when compared with an energy- and macronutrient-matched standard meat meal.
