It's no different to me than frequent weighings. I'm sure some people don't need or want the feedback but for me it's essential.
And using a CGM (I use 14 day Lifestyle) I can get readings whenever I want and also get data like trends that I can't get from finger sticks. I can see my blood glucose overnight for example which helps me tailor my meds and food to avoid the common overnight glucose rise that's pretty common.
So sorry NYTimes article but I'm going to disagree. I don't think enough people are encouraged to use CGM for example so that some real data can be extracted on diet compliance.
