Oh, I see. Do your best, because it's really important if you don't want to have diabetes for the rest of your life or get insuline-dependent. You must say too yourself that you have to do some sports, that don't means it haveto be heavy sports, walking for an hour a day is good too. Other examples are taking the stairs in stead of the elevator, use your bike to go to work, etc. Sport are good to for your heart disease, the sports are not bad, it's the food that you're eating probably.

Good luck man!

Cheers
