1- If I take a full meal,
rich in carbs like rice, the spike is as high as 215-220 after two hours.
2- after three hours the level is down to 140-155 even with this high carbs meal.
3-If I take the same big meal, rich in carbs, and go for a walk for one hour, the level would be 138-140 mg/dl after two hours.
Now average meal with average carbs.
