The Effects of Glucagon on Hepatic Metabolism in People With Type 2 Diabetes After Caloric Restriction (NCT05499702)
🩺 Plain-English Summary (8th-Grade Level)
Caloric restriction (and RYGB) improves insulin action and lowers fasting glucose, glucagon and EGP, without changes in postprandial EGP and glucagon concentrations. Caloric restriction also improves hepatic steatosis and lowers fasting AA. These changes may represent restoration of glucagon's hepatic actions. This experiment will determine whether caloric restriction improves glucagon's actions on hepatic amino acid, carbohydrate and lipid metabolism in T2DM in comparison to a baseline experiment performed separately in people with T2DM.
