I would exercise after eating, that way you give your body the energy and insulin to do the exercises. You can reduce the quantity of insulin pre-exercise by 20% (change this number to fit your body) to stop you going low mid exercise. Take something to eat like fruit and something to get you out of a hypo like Lucozade sport. Test regularly. Good luck
I think you should keep up the cardio until you get into your ideal weight before increasing your free weight exercises. That way you will be able to see the definition the weights give you
. One step at a time.
