Summary of preloading fish and meat before carbohydrate. Preload of fish and meat ameliorated postprandial glucose excursion by enhancing GLP-1 secretion and delaying gastric emptying. Preload of meat, which is rich in saturated fat (SFA) and monounsaturated fat (MUFA), enhances glucose-dependent insulinotropic polypeptide (GIP) secretion more than fish, which is rich in polyunsaturated fat (PUFA). As GIP promotes fat accumulation, frequent preload of meat before carbohydrate might well increase body weight.
