Starting and maintaining behavior change is rarely easy. If in doubt, think about your last three New Year's resolutions. How many are you still keeping?

A few years ago, when real-time continuous glucose monitors (CGMs) were introduced, my opinion was less than enthusiastic. I kept going back to the issue of accuracy. If blood glucose meters are within 15% of lab values, and CGMs are within about 15% of the meters, how useful could they possibly be? In my personal experience, I have seen plenty of CGM inaccuracies. And a day does not go by without a call or e-mail from a concerned client doubting the usefulness of their CGM system.
If you think you've mastered everything there is to know about carb counting, it's time for a little revelation. Not all carbs are created equal. Another factor to consider is the influence of the Glycemic Index.
