Why Food Beats Insulin to the Finish Line | Pre-Bolus Science, T1D

Half the planet is watching the World Cup, so Neil explains the mechanism of the post-meal spike in soccer terms. Your food is the striker, already past the defense. Your insulin is the defender who got subbed in late and is still jogging back. That mismatch is the entire reason you spike.This is the "how it works" episode. Regular rapid-acting insulin takes about 15 minutes to start, peaks around an hour, and lasts three to four hours. Your dinner carbs hit your bloodstream almost immediately. Dose them at the same time and the food scores before the insulin is even in the game. The fix is simply to put your insulin in first, so they arrive together and your CGM line stays flat and boring, which in type 1 is the dream.In this episode:How fast rapid-acting insulin actually works vs. how fast carbs hitThe pharmacokinetics of insulin timing, in plain EnglishWhy a "flat and boring" CGM is the whole goalHow pre-bolusing matches your insulin to your foodThis Week's Challenge: Keep watching the gap between your dose and your first bite at dinner, and now you know what it means.
