This is a feasibility study evaluating the potential to utilize a continuous glucose monitoring system (CGMs) on a temporary basis, during participation in a lifestyle medicine program, to help improve the compliance with healthy lifestyle changes for people with Type 2 diabetes (T2DM) and prediabetes (PD).

Glucose peaks after eating are an indication of the level of insulin resistance and the severity of disease in patients with T2DM. Many lifestyle factors affect the glucose elevation, including the glycemic index of food, timing of eating, physical activity, stress and sleep.

In practice, a glycemic profile, consisting of multiple glucose measurements before and after meals throughout the day, has sometimes been helpful in educating patients concerning the effects of their eating habits on blood sugar levels.

Would temporary use (8-10 weeks) of a continuous glucose monitoring system (CGMs) be a useful adjunct during lifestyle education in patients with T2DM or PD?

The purpose of this feasibility study is to evaluate the effectiveness of a CGMs on a small sample of patients while they are enrolled in a lifestyle medicine class, to:

• identify any logistical issue involved
• verify that useful data can be obtained for analysis
• inform development of a larger controlled study

Eligible subjects who have consented to the study, and have had the baseline data gathered as part of their participation in the Lifestyle Medicine Clinic, will be given a CGMs device and supplies, and instructed in how to utilize these. They will set up the app on their smart phone to provide them with feedback on their glucose level to correlate with their lifestyle activities.

The FDA approved CGMs utilizes a small filament-like probe that is entered into the skin and measures sugar levels of the interstitial fluid of the subcutaneous tissue. This correlates with blood glucose levels.

Daily, the subjects will enter data into their smart phone app, which will include:

• time of arising in the morning, and perceived quality of sleep
• time and description of food and beverages consumed
• time and description of physical activity
• time and description of stress management activities
• time and duration of naps
• bedtime

Once daily, the subject will complete a reflection entry in a diary on their glucose levels over the last 24 hours in relation to their logged lifestyle activities.

At the completion of the 8 sessions of The Lifestyle Medicine Clinic, participants will complete a survey asking open ended question concerning the use of the CGMs.

Inclusion criteria:

• be able to read and write English.
• be enrolled in The Lifestyle Medicine Clinic, taught by Dr. Drozek
• be diagnosed with type 2 diabetes (T2DM) or prediabetes (PDM)
• be at least 18 years of age
• be comfortable wearing a sensor continuously for up to 10 weeks
• have a smart phone and be comfortable utilizing apps
• be able and willing to daily enter data concerning food consumed, exercise, stress management activities and sleep.
• be willing to complete a daily reflection on the relationship of their blood sugar to lifestyle activities.
• be willing to complete a survey at the completion of the project about their perceptions of utilizing continuous glucose monitoring (CGM)

De-identified data will be posted after completion of the study.
