RETRACTED: Whey protein preload enhances the active GLP-1 response and reduces circulating glucose in women with polycystic ovarian syndrome

Polycystic ovary syndrome (PCOS) increases risk for development of type 2 diabetes. Whey protein ingestion before a carbohydrate load attenuates blood glucose. For our exploratory, case-control study design, we hypothesized that 35 g whey protein isolate (WPI) preloading would increase postprandial incretins and reduce hyperglycemia in women with PCOS. Twenty-nine age-matched women (PCO = 14 and CON = 15) completed oral glycemic tolerance tests...
