Primary: Change From Baseline in Postprandial Area Under the Curve From Time 0 to 8 Hours (AUC[0-8]) for Active Glucagon-like Peptide-1, The concentration of glucagon-like peptide-1 (GLP-1) in blood before and up to 8 hours after eating (postprandial) was plotted and the area under the curve calculated using the linear trapezoidal rule at Baseline and on Day 11. Least squares means of the change from Baseline to Day 11 were obtained using an analysis of covariance (ANCOVA) model with treatment as fixed effect, and Baseline postprandial AUC (0-8) of active GLP-1 as a continuous covariate., Baseline and Day 11; samples were taken at -15 min and -5 min (pre-meal), and 15 min, 30 min, and 1, 2, 3, 4, 6, and 8 hours (post-meal). | Secondary: Change From Baseline in AUC(0-8) of Postprandial Plasma Glucose, The concentration of glucose in blood before and up to 8 hours after eating (postprandial) was plotted and the area under the curve calculated using the linear trapezoidal rule at Baseline and on Day 11. Least squares means of the change from Baseline to Day 11 were obtained using an ANCOVA model with treatment as fixed effect, and baseline postprandial AUC (0-8) of plasma glucose as a continuous covariate., Baseline and Day 11 at -15 min and -5 min (pre-meal), and 15 min, 30 min, and 1, 2, 3, 4, 6, and 8 hours (post-meal).|Change From Baseline in Postprandial AUC(0-8) of C-peptide, The concentration of C-peptide in blood before and up to 8 hours after eating (postprandial) was plotted and the area under the curve calculated using the linear trapezoidal rule at Baseline and on Day 11. Least squares means of the change from Baseline to Day 11 were obtained using an ANCOVA model with treatment as fixed effect, and Baseline postprandial AUC (0-8) of C-peptide as a continuous covariate., Baseline and Day 11; samples were taken at -15 min and -5 min (pre-meal), and 15 min, 30 min, and 1, 2, 3, 4, 6, and 8 hours (post-meal).|Change From Baseline in Postprandial AUC(0-8) of Insulin, The concentration of insulin in blood before and up to 8 hours after eating was plotted and the area under the curve calculated using the linear trapezoidal rule at Baseline and on Day 11. Least squares means of the change from Baseline to Day 11 were obtained using an ANCOVA model with treatment as fixed effect, and Baseline postprandial AUC (0-8) of insulin as a continuous covariate., Baseline and Day 11; samples were taken at -15 min and -5 min (pre-meal), and 15 min, 30 min, and 1, 2, 3, 4, 6, and 8 hours (post-meal).|Change From Baseline to Day 11 in AUC(0-8) of Appetite Sensation, Appetite sensations were measured using a visual analog scale (VAS) questionnaire. Participants were asked to indicate their level of fullness, hunger, satiety, and prospective consumption (how much do you think you can eat?) on a 100 mm line ranging from "Not at all" (0 mm) to "extremely" (100 mm). Appetite sensation scores before and up to 8 hours after eating were plotted and the area under the curve calculated using the linear trapezoidal rule at Baseline and on Day 11. Least squares means of the change from Baseline to Day 11 were obtained using an ANCOVA model with treatment as fixed effect, and Baseline postprandial AUC (0-8) of appetite sensation VAS score as a continuous covariate., At Baseline and Day 11, every 30 minutes, starting 1 hour before eating until 8 hour after the meal.|Change From Baseline to Day 11 in 24-hour Average Plasma Glucose, Plasma glucose was measured by Continuous Glucose Monitoring System (CGMS). CGMS measures glucose every 5 minutes, starting in the fasting state 8 hour prior to the standardized breakfast (12 AM) until 16 hours after the breakfast. The average 24-hour plasma glucose concentration was calculated. Least squares means were obtained using an ANCOVA model with treatment as fixed effect, and Baseline 24-hour Glucose Measured by CGMS as a continuous covariate., Baseline (Day -1) and Day 11, from 12 AM through 24 hours.
