Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Glucose Levels	Blood will be obtained to measure glucose after a glucose tolerance test. The glucose tolerance test involves an overnight fast and then participants will ingest a drink containing 75 grams of glucose with blood obtained over a 120 minute period.	Baseline and 8 weeks
Primary	Insulin Level	Blood will be obtained to measure insulin level after a glucose tolerance test. The glucose tolerance test involves an overnight fast and then participants will ingest a drink containing 75 grams of glucose with blood obtained over a 120 minute period.	Baseline and 8 weeks
Primary	C-Peptide Level	Blood will be obtained to measure c-peptide level after a glucose tolerance test. The glucose tolerance test involves an overnight fast and then participants will ingest a drink containing 75 grams of glucose with blood obtained over a 120 minute period.	Baseline and 8 weeks
Secondary	PROMIS 10 Questionnaire	Brief 10 question multiple choice survey	8 weeks
