How does diet affect diabetes

This is probably wrong, but a diet can affect diabetes in a good and bad way.

If you eat healthier and eat less and less little by little you are doing a good diet (i don't like calling it a diet to me i call it eating healthier.). But if you decide to not eat at all or eat to little to fast it can get you less big? but it will create a yo-yo affect and you will be skinny but then if you eat wrong instead of it taking a while to be big aging it will happen faster. And you'll constantly be changing body shapes.

i think it's the first one because doctors aren't the ones who get rid of the old needles. most of them time it's not even doctors who give you shots, it's nurses.
