Postprandial Glucose Spikes: Normal Physiology, Not a Disease to Flatten

Summary

In a metabolically healthy person a post-meal glucose rise is **normal physiology, not a problem to "flatten"** — peaks to ~140 mg/dL (7.8 mmol/L), and transient excursions to 160–180, are typical and clear within 2–3 hours — and the real metabolic signal is the **trajectory and the integrated picture (HbA1c, fasting insulin/HOMA-IR, a pattern of high responses)**, NOT the height of any single spike; the viral "spike anxiety" framing inverts this, treating every transient bump as pathology and selling flattening "hacks" whose evidence comes from diabetics, not the healthy audience being market
