Adherence

A web-based digital therapeutic program (Prevent) based on the Diabetes Prevention Program (DPP) curriculum significantly reduces body weight and A1c levels in adults with prediabetes, with effects sustained for at least 2 years.

If you have prediabetes, a structured online program that combines weekly educational lessons, daily weight tracking, and access to a health coach and peer support group can help you lose about 4-5% of your body weight and lower your A1c. This approach works by making lifestyle changes manageable and sustainable over two years, even after the initial intensive phase ends. You need internet access and the ability to perform light physical activity.
