I'll second Beefsister's advice, and I'll add that you look up a man by the name of Dr. Richard Bernstein. He's a type-1 diabetic physician that's been keeping his condition in check for almost (or maybe more than) 50 years by following a very low-carb diet, to the point where he no longer requires medication. His methods have also been followed very successfully by several type-2 patients.
1) eat real food - more vegetables, moderate meat, moderate fruits, less grains, less sugar, less vegetable oils.
2) exercise - moderate intensity cardio, sprinting, heavy lifting, dedicated stretching and mobility.
3) live - relax, de-stress, meditate.
