Beyond macronutrients, meal timing andd order matter. Eating protein and vegetables before carbohydrantes can reduce postprandial spikes. Skipping meals can lead to rebound hyperglycemia due te contra-regulatory y containes like glucagon and cortisol.

These systems aim to prevent hypoglycemia by automatically raising glucose with tiny glucagon doses whene the CGM signals a pending low. Early trials show nearly-normal glucose profiles with dramatically reduced variability. The iLet bionic panenas is one such device constructly in development.
