I have type 2.
It is under control by diet, but I really need to lose weight.
Recent studies have shown it CAN be reversed, you need to cut out all forms of sugar and do some exercise.

This forces the body to use up the stored sugar, and kick-starts the body into its "normal" functions.

Haven't done it myself yet, needs considerable willpower over a few months, and then more not to slip back into bad habits.
