Diabetes is one of the most pervasive and expensive chronic diseases: It affects an estimated 30.3 million people in the United States and costs a staggering $245 billion per year to treat. In addition there are 84.1 million adults in the United States with high blood sugar levels in danger of developing type 2 diabetes. It is widely acknowledged that the most effective method of treating these prediabetics so they don’t become full-fledged diabetics is diabetes prevention programs (DPPs) that follow a protocol validated by the Centers for Disease Control and Prevention (CDC). But the challenge has been to get people to enroll in them in the first place and stick with them if they do.
