At baseline, enrolled candidates will be required to keep a daily food and beverage record for 2 weeks as well as blood sugar log of at least 2 measurements a day (fasting and pre-dinner). Candidates will have an initial nutrition/diabetes consult with dietitian. They also will be asked to do a 24-hour urine collection once a week (2 times during the 2 week period) for quantitative assessment of glucosuria. During those 2 weeks individuals will come for GCRC outpatient visit once a week for weight, blood pressure, and blood sugar check.
