I started a thread some time ago asking people about their tech, and since I have much of my personal data going in into Google Fit, i.e., CGM, fitness/activity, weight/BF, and sleep, I paired that with some programming to do some analysis. Similarly, with so much data being collected, it should be easy to do some preliminary analysis at scale.
Although I found, and continue to find, some relationships between data points, nothing correlated with my glucose numbers.
