As I see it, one can opt for calorie control, which will make you miserable and probably regain the weight quickly,(and this would only work
if insulin was reduced aswell), or you can work
along the principles of how
fats and carbs are metabolised. If you take a certain amount of insulin, you must take a certain amount of carbs(feeding the insulin), and the end result will be weight maintenance or weight gain. As soon as we feed insulin with unrequired energy, it is deposited as fat.
