Brief Summary

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

The experimental approach in this study intends to investigate the role of hepatic glycogen content on nocturnal regulation of endogenous glucose production including the relative contributions of glycogenolysis and gluconeogenesis and the extent to which this differs between subjects with type 2 diabetes and subjects without diabetes. Both participants with type 2 diabetes and participants without diabetes will be studied after consuming either a low carbohydrate (no glycogen loading) or high carbohydrate (glycogen loading) diet.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Physiology study for looking at glycogen loading vs non loading in improving nightime glucose tolerance by increasing glycogen in liver and resulting higher glycogenolysis at night.
