Continuous glucose monitors for non-diabetics — overhyped?
I wore a Levels CGM for 2 months. Main finding: my glucose responses are completely normal and boring. Rice spikes me, protein doesn't. Groundbreaking stuff. The $200/month subscription feels like paying for anxiety. For metabolically healthy people, is there any actual longevity benefit to CGM monitoring?

I had the exact same experience. Two months of data confirmed that I should eat fewer refined carbs, which I already knew. Not worth the ongoing cost.
The value is in the initial learning phase. Wear one for 2-4 weeks, learn your personal responses, then stop. No need for continuous monitoring.
For non-diabetics, a quarterly fasting insulin + glucose + HbA1c panel gives you 90% of the useful information at 5% of the cost.
Disagree — I found huge value in seeing how stress and sleep affect my glucose independently of food. That insight alone was worth it.
