I was able to test the Freestyle Libre device for a couple of months for a friend's research. While I don't have diabetes, it was very enlightening to have constant access to my body's glucose (and indirectly glycogen) levels. I had a near-real-time data stream. I have practiced intermittent for over a decade, using an 18/6 split. It was so amazing to see my glucose nose dive around midday, then rise and stabilize after about an hour. I assume this was my body switching its energy source from depleted glycogen stores in the liver to lipid (fat) gluconeogenesis. I know this isn't what the device was designed for, but this would be a complete game-changer for bespoke diet/well-being plans. After a bit of trial and error, you'd know exactly when and what to eat. After the research ended, I honestly felt like I had lost a sense. My body was running in blind mode again. I would have continued using the device, but at retail, each sensor is around $70 USD. I hope for a future in which wearables and wireless body monitoring devices become the norm, rather than the exception. There is so much data to be gathered. Sucks that Abbot has killed this OSS project.
