The purpose of this three-month, randomized, controlled trial is to compare the difference in change in 14-day CGM-derived TIR (% time with glucose 70-180 mg/dL) from Baseline to 3-months Post-Dietary Change in participants with T2D who are assigned to use either BGM or CGM. The difference in mean blood ketone levels and additional glycemic endpoints will also be compared, and several exploratory endpoints, including medication changes, dietary intake, and body weight will be described.~The study also includes a three-month Follow-Up period (months three to six), where participants will remain using their randomly assigned glucose monitoring modality (e.g., BGM or CGM); this period will help assess durability of the results found during the intervention.~This study will provide insights into how continuous feedback from CGM affects glycemic outcomes, such as TIR and HbA1c, compared to the standard method of BGM. It is important to understand if the methods of glucose monitoring differ, because greater TIR and lower HbA1c are associated with reduced risk of diabetes complications.~While many studies have compared the differences in glycemic outcomes between BGM and CGM, this study compares differences between the two glucose monitoring methods as part of a randomized, controlled intervention in people with T2D where dietary patterns will be adjusted. It is possible that this study will help demonstrate whether the continuous feedback provided by CGM influences adherence to dietary guidance.
The purpose of this study is to learn whether there is a difference in the amount of time glucose (blood sugar) stays within a target range (glucose 70 - 180 mg/dl) when using either continuous glucose monitoring (CGM) or fingerstick blood glucose monitoring (BGM) in people with Type 2 diabetes who participate in the Virta Treatment program.
