It's working.  Getting my carbohydrates from vegetables is allowing me more satisfying meals.  I learned that I can eat a little bread without spiking my blood sugar.   

Here's how to find out what works for you.  Test your blood sugar 2-2 1/2 hours after eating to see what your food has done to you blood sugar levels. 

Remember, over 200 dl/mg, glucose is damaging nerves and organs.  Anything that spikes your blood sugar over 200 is dangerous.  Rice and white potatoes are in my "no eat" zone because carb for carb they send my blood sugar higher that foods of equal carbs.

Develop your personal "no eat" zone.  Test your blood sugar several times a day.  A dietitian's advice can help, but only you can personalize your food choices to fit the way your body uses carbohydrate.
