What is the Cure for Diabetes?

It’s said that there is no cure for diabetes. It’s only managable. I see this as questionable since it’s been known that some people who have Type 2 diabetes from being overweight, have been diabtetes free once they have lost weight and changed eating habits. I am not a doctor so I can’t honestly say this is 100% true. So the true cure is probably just prevention. Live healthy, eat healthy and get plenty of excersize!
