You know ladies, everyone is different becuz, last Monday night, I had a small, new potato with my dinner of lean meat and veggies -- and the next AM, my blood sugar reading was only 5.0/80. For me, the trick is HOW MUCH? When I say small potato, I mean one that is only 2-3" across. My DH and I separate the small ones out for me and he eats the larger ones (medium & larger); plus we always buy NEW potatoes (which have less starch in them) and we eat them with their skins on too.
As you can tell, it is a matter of trial & error to see which foods send our sugars soaring and which ones don't. I read somewhere that there is a degree of starch levels -- veggies, fruit, whole grain breads, then beans, brown rice, wg pasta, and new potatoes/corn/peas, etc.
If you think that you can honestly forgo bread or rice or pasta or potatoes for the rest of your life, then do so. I know for me that is not a reality, so what I am using is portion size as my #1 guide and it is working for me.
I measure everything; and it has become second-nature to me now. Sure, there are some days that I eat just a nice steak with a nice veggie mushroom medley with 1/4 cup kniblet corn, and a salad (like tonight for instance) -- but the rest of the time, I eat what I like and enjoy of those foods; and am just careful how much of them.
I know that there are some things that make me want to binge; and I have now identified them on a list -- chippies, nachos, hickory sticks, popcorn, cookies, salted nuts, pretzels, etc. It's those munchie things that get me, so now I forgo them and have replaced them with something healthier.
Have a great day -- time to make that nice steak dinner ...
