To treat a low blood sugar you will want to eat a form of carbohydrate that is easily digested and absorbed so that the sugar will enter the bloodstream quickly. Do not use chocolate bars, ice cream or cookies, all of which contain significant amounts of fat, which slows down the digestion of the sugar. I have type 2 diabetes and my doctor keeps telling me to lose weight. Type 2 diabetes is associated with insulin resistance. In other words, the body is not able to properly use the insulin that it makes which causes the blood sugar to go too high.
Weight loss can improve insulin resistance therefor improve blood sugar control.
Exercise has a similar benefit in improving insulin resistance. Weight loss and exercise are the cornerstone to treating type 2 diabetes. I have type 2 diabetes and control my blood sugar with diet and exercise. Exercise does burn glucose from the blood and can lower the blood sugar. Besides, many people exercise to help with weight loss, and if you snack you will be burning the fuel from your snack, which means you wont be lowering your blood sugar or burn much body fat.
