A quiet shift is underway in metabolic medicine. A recent Nature study shows that continuous data from wearables—heart rate, sleep, activity—combined with routine labs can detect insulin resistance years before traditional tests. Not snapshots, but a "movie" of physiology.

This opens a wider window for prevention: simpler interventions, earlier action, better outcomes. The future may lie not in waiting for thresholds, but in tracking trajectories.
