I started about two years ago. It is an insurance coverred program that provides the glucose/keto self checking devices and allows you to upload the results online so they can monitor the status. There were some side effects, like rash (not ichy), sleepless.... the side effects went away within a month. I stopped Keto diet after finding out my cholestorol got higher.
I am still on low carb diet. Overall I have better energy now.
