Ok I understand the principle about carbs and I personally have seen my own bg lower by reducing them.

What I am struggling to get my head around is :-

Why exercise? If you exercise your cells cry out for more glucose, but they can't get it because of insulin resistance.
So your liver dumps more glucose any yet for some reason bg reduces.
Logic say it should increase ????
What am I missing????

Strenuous exercise normally does increase BG; but I find a walk after a meal does reduce it. I understand it increases insulin sensitivity.

Exercise creates GLUT4 transporters in muscle tissue. Glucose gets into cells by either insulin or a GLUT transporter, so if your exercising and your blood sugar reduces it could be because glucose is getting into the cells via GLUT transporters - https://en.m.wikipedia.org/wiki/GLUT4

And long term exercise is thought to make the cells more insulin sensitive.
 
I always thought that if you were low carbing, the ATP used for the exercise has to come from somewhere and so it is likely to come from proteins and fats... fat reserves are likely to be the first option....

So as an underweight T2 and keeping my BG in check by low carbing, I should become a couch potato if I want to gain weight :)

Exercise is a must for diabetes as it will increase the effectiveness of insulin. The body must remain active and in good health, to lose condition is to invite further complication through depleted metabolism. Body fat content and good muscle tone aid in effective control of diabetes. Good circulation to the extremities is vital. Even if the glucose levels rise, they will subside. Keeping fit and active is vital for effective control.
