You can get diabetes from too much sugar. Type II anyway. Though as a Type I I resent that. You're not really a diabetic if you just have an insulin resistance and can cure it by eating better. Now, the ones that can't cure it and need an amount of insulin, that's different. But I'll tell you what. I will GLADLY trade my non-working pancreas for your slightly used but still functioning one. If the doctor told me "eat better and exercise every day and you'll cure your diabetes," one thing is certain. I'd be at the gym ever bloody day, eating light salads and carrots.
