Exercise before breakfast?

Italian_Buju

I am a type one diabetic, so I eat breakfast and lunch at roughly the same time every day. Typically, I wake up around 6am, have breakfast at 10am and lunch at 2pm. I want to start an exercise class at the Y, but it is at 9am.....is it ok to do an hour of exercise and then eat breakfast? Before ten am, all I have is tea and water.
