CGM Study of 62,000 People: Average Glucose Beats HgbA1C at Detecting High Insulin
arjunrajlab · x · 2026-11-11
A first preprint study (medRxiv) from PLC analyzes Levels platform data from 62,000+ people with linked food logs, CGM traces, labs, and step counts. Key findings: (1) CGM average glucose outperforms HgbA1C at detecting elevated fasting insulin, especially in younger healthy individuals even after controlling for BMI; (2) glucose spike width — not height, frequency, or carb sensitivity — carries independent metabolic signal. Commenters see such analyses as a glimpse of quantitative medicine's future.
