Measure
DEXCOM G6 RT-CGM
These participants will wear blinded continuous glucose monitoring for 10 days at baseline and 14 weeks. They will also complete real-time continuous glucose monitoring (RT-CGM) for 10 days at 2 weeks and 6 weeks. They will receive Nutrition and exercise counseling at week 2 and 6. They will also receive additional training on continuous glucose monitoring.
Blinded CGM
These participants will have blinded continuous glucose monitoring(CGM) at the baseline and last 14 weeks. They will not wear continuous glucose monitoring at the interim appointments. They will receive 2 session of nutrition and exercise counseling at week 2 and 6.

Timeframe: 14 weeks

Population: All participants in the CGM Intervention group. Blinded group did not complete this survey

Experiences of CGM @Joslin 2009 scale of (5) strongly agree or (1) strongly disagree about statements/questions that measured the amount of satisfaction that was derived from continuous glucose monitoring. The larger the score the more satisfied participants were with CGM. 100 being the max score and 20 being the min score

Starting The Conversation (STC) is an eight-item simplified food frequency instrument/questionnaire a max score of 16 indicates poor food choices and a minimum score of 0 indicates good food choices. Results reported is change from baseline score with a negative score being a marker of improvement in food choices and a positive score being worsening of food choices
