Use of Mobile-based Technologies to Improve Diabetes Self-management and Postprandial Glucose Control

The intervention will be three (3) months in duration and will entail use of a smart phone
app for real-time data logging to identify factors causing glycemic variability, as well as
use of a web-based nutrition education program. The investigators postulate that the
interactive nutrition education curriculum — which will provide feedback to patients about
the inter-relationship between their food intake and postprandial glucose profiles, as well
as practical guidance for improvements — will lead to a change in food choices and improved
post-prandial glucose control.
