Unless I had a medical need, I would not want to wear any monitoring devices 24/7. I think it would contribute more to overall anxiety and stress than do anything helpful.
For example, if I could make my liver 20% healthier by eating more moderate portions of bread in a meal where I plan to eat dessert, it would be useful to know that.
On the other hand, I don't think I have to wear the device forever to gain this information. I could learn about what makes my blood glucose spike after a month or two, and then just carry that knowledge with me going forward.
