Continuous glucose monitors (CGMs) provide valuable insights but are often misunderstood and misused by people without diabetes. We debunk common misconceptions about glucose monitoring and explain why a flat glucose line isn't necessarily optimal for everyone.

• CGMs measure interstitial fluid glucose through a filament and algorithm, not actual blood glucose
• Healthy glucose range for non-diabetics is 70-140 mg/dL with approximately 98% time in range
• Some variability in glucose is normal and expected, including post-meal spikes
• Individual "glucose phenotypes" explain why people respond differently to the same foods
• CGMs can reveal how sleep, stress, and lifestyle factors affect blood sugar beyond just food
• Short-term CGM use (10-14 days) provides the most actionable insights for most people
• Real-time feedback from CGMs often drives positive behavior change even without detailed analysis
• CGMs should be used alongside standard blood work like fasting glucose, insulin, and A1C tests
• Continuous monitoring can create food anxiety in some people and isn't necessary for everyone
• Focus on patterns and context rather than obsessing over every small glucose fluctuation
