Absolutly but would this device help people to diagnose that ? and things like Z2 workouts use sugar from blood, > Threshold intervals cause adrenline to be released which spikes your blood sugar, cause people to be confused ? And the fact that zinc makes you less insulin sensative ?
There are enough queries in these forums with people asking “I just got my first HR monitor, and my heart rate is about 80, am I about to die” that my point (was going to say concern) is that it is more likely to cause people to think they don’t have to eat because there sugar level is ok, rather paying attention to effects different food have on glucose levels
