as someone who eats relatively healthily but has no problem consuming processed foods (but tends to avoid excessive sugar), when I wore a cgm out of curiosity it was very clear that such a device offered me nothing, as a non-diabetic, non-pre-diabetic person the data showed that the body responds in line with input never exceeding tolerances.

It was impressive just how uninsightful it was, I love quantifying my workouts, my nutrient intake, etc, but the cgm added absolutely nothing.
