Post-Meal Walks: A Real, Free Glucose Lever (Just Not Half Your Spike)

Summary

A short, easy walk **after** a meal genuinely and reliably blunts that meal's glucose spike — through an insulin-independent, contraction-driven mechanism that works even in insulin-resistant people — and it's one of the best free, near-zero-effort metabolic levers there is; the honest magnitude is **moderate** (roughly a 10–20% reduction in the post-meal rise, biggest in the first 30 minutes), strongest in healthy and prediabetic people, and the place it gets oversold is the leap from "blunts the spike today" to "controls your HbA1c long-term" — that part the evidence does not support. ---
