Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Second-meal phenomenon denotes the effect of a prior meal in decreasing the rise in blood glucose after a subsequent meal. This phenomenon occurs in normal subjects while it is not clear whether it is also observed in type 2 diabetic patients. This study aims to define whether the second-meal phenomenon occurs in type 2 diabetic patients. We will also seek for the mechanism.
