Food Order ("Carbs Last"): A Real, Free Lever That Shrinks at Life-Scale

Summary

Eating vegetables and protein **before** carbohydrates ("carbs last") genuinely blunts the post-meal glucose and insulin spike — the acute effect is robust and sometimes large (glucose-area reductions of ~35–75%, peak cuts ~30–45%) — but the lever **shrinks hard when you scale from one test meal to a life**: the only pooled meta-analysis found **no significant HbA1c benefit** over standard dietary advice, so it's a free, mechanistically sound fine-tuning tool for managing excursions (best in T2D, prediabetes, gestational diabetes), not the long-term metabolic "hack" the glucose-wellness scene
