There is a reason you are seeing that! Beside the reasons for increased sensitivity during and right after exercise that I mentioned here ==\> [How exercise increases the effect of insulin and carb usage](https://forum.fudiabetes.org/t/how-exercise-increases-the-effect-of-insulin-and-carb-usage/3857)

There is a reason it affects you the whole time. Really cool stuff, I will post it later.
