Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
No Intervention: Control Group
This arm will receive generalized nutrition therapy throughout the study. Participants will receive dietary recommendations based on their needs and will be educated about the recommended amount of carbohydrates for each meal and the carbohydrate choices. Participants will also be provided with a CGM device; however, participants will be blind to the CGM recordings until the end of the study. |
|
Experimental: Intervention Group
This arm will receive both individualized nutrition therapy and generalized nutrition therapy throughout the study. Participants will receive dietary recommendations based on their needs and will be educated about the recommended amount of carbohydrates for each meal and the carb choices. Participants will also be provided with a CGM device and will be educated to review their blood glucose measurements and record above range measures along with time, types and amount of food items consumed, cooking method, and any type of physical activity within one hour before or after the meal. This information will be reviewed by one of the research staff at each visit and will be used to set individualized goals for modifying diet and controlling blood glucose. Participants will visit every 10 days for 30 days to conduct measurements, replace their CGM, set new goals based on their food diary and CGM recordings, and receive further dietary recommendations. |
