CGM Plus GEM in Prediabetes

The intervention group will be given Libre 2 supplies for 4 months, an activity monitor, and the 4-chapter GEM paper guide. The intervention group will complete a virtual or inperson study visit where they will receive instructions on how to apply their unblinded Freestyle Libre and connect it to the study account, as well as how to register their Fitbit to the study account. Participants will receive one telephone call to review use of the GEM Guide and call at two weeks and six weeks later when the probability of dropouts from lifestyle intervention peaks. Participants will follow the self-directed GEM guide for 4 months (a 1-month treatment period followed by a 3-month maintenance period) while wearing a FitBit activity monitor and a Freestyle Libre 2 CGM.
