Before exercising consider these general guidelines relative to your blood sugar level:

-  <100 mg/dL: Eat a small carbohydrate-containing snack, such as fruits, before you begin your workout

-  100 to 250 mg/dL: You're good to go

-  >250 mg/dL: Before exercising, test your urine for ketones, wait to exercise until it indicates absence or a low level of ketones in your urine
