Abstract
The meal-induced rises in plasma GIP, serum insulin, and blood glucose were studied after an overnight fast and after a 34-h fast in six healthy men. After the 34-h fast, the postprandial mean plasma GIP level at 120 min and the mean serum insulin and blood glucose levels at 60 and 90 min were significantly higher than those seen after the overnight fast.
