Outcome Measures
Primary Outcomes (2)
Plasma Insulin
A Hyperglycemic clamp was performed once during each study period to assess glucose stimulated insulin secretion. Glucose is infused intravenously to maintain blood glucose near 200 mg/dL to stimulate insulin secretion. During this time plasma insulin levels were measured and the insulin response is reported as the incremental increase over the first 10 minutes of glucose administration.
at the end of each 1 month study period ( 3 times in total)
Plasma Glucose
Fasting plasma glucose, measured during hyperglycemic clamp
at the end of each 1 month study period ( 3 times in total)
