This is a program evaluation that will evaluate the effectiveness of Mastering Diabetes, a therapeutic lifestyle change (TLC) program to control prediabetes and type 2 diabetes.

Lifestyle change, focused on dietary change, physical activity, stress management and control of unhealthy substances has been demonstrated effective in preventing the progression of prediabetes, as well as reversal of diabetes and type 2 diabetes mellitus (T2DM).

This will be a nonrandomized controlled study. Participants will self select to be a part of this intervention. The control data will be aggregated matched data from participants in the corporate wellness program at Memorial Health System, who choose not to participate in the intervention.

Study participants will have met the inclusion criteria. Potential participants will be provided with a short summary of this program as a potential activity for their participation, with a link leading to a landing page, which will explain the study in more detail, and will include a link to the consent.

If the potential participant is interested, they can click the link to move to the on line consent. If they agree to the consent, they will be taken to an on line HIPAA release form, which will also need an electronic agreement to be enrolled into the study signified by typing in the participant's name and date of birth.

Once this is completed, an email with an enrollment code and link to Mastering Diabetes will be sent the participant.

Mastering Diabetes Program Description:

The Mastering Diabetes Program is based on the Mastering Diabetes Method, which is based on almost 100 years of evidence based research demonstrating the effectiveness of a low-fat, plant-based, whole-food diet to reverse insulin resistance. Members are provided with a step-by-step online course that educates them how to transition to a low-fat, plant-based, whole-food lifestyle and reduce the overwhelm associated with ineffective pharmaceutical medication and ineffective dietary advice.

The online course provides members with detailed information about the root cause of insulin resistance, the effect of a high-fat diet on increasing insulin resistance, how to achieve excellent blood glucose values in the short-term and in the long-term, what laboratory tests to get to measure progress, an overview of oral diabetes medication and insulin, how to track hour-by-hour decisions for excellent blood glucose control, how to lose weight permanently using a low-fat, plant-based, whole-food diet, how to buy food, where to buy food, how to prepare food easily, the benefits of intermittent fasting for improved insulin sensitivity, how to perform an intermittent fast for excellent results, how to adopt an exercise regimen, how to control your blood glucose before, during, and after exercise, how to change your breakfast, lunch, dinner, and also provides members with a collection of delicious and simple recipes.

The program also provides members with direct access to expert coaches via an online community containing thousands of others living with all forms of diabetes, including type 1 diabetes, type 1.5 diabetes, prediabetes, type 2 diabetes, and gestational diabetes. In addition, members get access to live biweekly Q&A videoconferences in which they can interact with coaches and personalize their experience. The cost of full coaching program is $399 for the first 3 months, then $99 per month thereafter.

Participants, having enrolled in the wellness program, will already, as a part of that study, have agreed to have data collected at baseline and yearly thereafter, including BMI, blood pressure, resting pulse, lipid panel, hemoglobin A1c, health risk assessment survey, absenteeism and health claims data at baseline and yearly thereafter. If not collected within 60 days, a new set of data will be collected to serve as baseline for this study. This is not specific for this study, but is the case for any new program activity that a participant in the corporate wellness study begins.

Specifically for this study the health risk assessment data collection (including lab analysis) will also be repeated at 12 weeks. The lab work is accomplished at any MHS lab facility, according to current medical system standards.

Participant health claims data will also be evaluated, beginning with the prior year's data, if available from MHS Human Resources, being utilized as a baseline, and followed for the subsequent years of the study.
