Whey Protein Ingestion and Glucose Control in Pre- and Post Diabetic Individuals
University of Arkansas
Summary
To examine the effects of twice daily whey protein consumption on blood glucose and insulin in pre-diabetic and diabetic individuals
Description
Protein consumption in the morning has been shown to reduce appetite and caloric intake (19). In addition, premeal whey consumption reduces post prandial blood glucose, reduces gastric emptying rate, and increases peak blood insulin (10). Thus, it is proposed that ingestion of whey protein within 1hr of waking (and prior to breakfast) and 30 minutes prior to dinner will be more effective in suppressing appetite, carbohydrate intake, and glucose AUC. Ingestion upon waking will mitigate the cortisol-induced drive for carbohydrate intake. Ingestion prior to dinner, the most frequently consumed an…
