The big innovation here is actually the CGM sensor. Having a sensor on your body that passively gives you information about how your body reacts to food, exercise and medication is amazing. I wrote a post last year on how it TOTALLY changed my life: https://medium.com/south-park-commons/the-wearable-that-chan...
Thank you for sharing this post. I enjoyed how similar the feedback loop for your experiments was to optimizing code for performance, and it makes me (someone who doesn't have diabetes) want to try CGM. However, I don't think I can get it through insurance. It costs about $42.99 for a 10-day sample, so maybe I'll try a 10-day sample to play around with it.
