| Funny that you ask this now...
I have had D for nearly 13 years now and have JUST NOW (finally) gotten to the point where I am taking control of my carb/candy intake.
I have been doing low(er) carbs for about two months now, with great success for my blood sugars, limited success for weight loss. But I'm doing it more for my blood sugars at this point, although I have lost about four pounds, which is always good. :O)
I gained 65 lbs. with my first daughter that has never come off, which has really screwed with my insulin requirements, on top of my heavy carb intake. I too, was taking in around 200-300 per day until a couple of months ago when I made this jump.
It has taken me a long time to get to a place where I can accept that this is not a diet, it's a life-change and a way of living that involves a total re-evaluation of my relationship with food.
That having been said, I have cut my carbs to 90-105 carbs per day, and on some days having only around 50, but interestingly, I never feel deprived. Part of that is because I EAT WHATEVER I WANT. I just eat LESS of it. If I want hot chocolate, I have a cup of hot chocolate, complete with marshmallows... It's just a very small cup... If I want pasta, I have pasta (I'm eating dreamfields, though, because it doesn't affect my BG the way others do). If I want a piece of bread and butter, I have one, I just am very careful about what breads I buy (always super-high fiber ones).
It takes more time to count it all out, yes, and that is sometimes hard when I'm rushing out the door and need to eat. But after a few weeks, I now know exactly how much of something I can eat, which helps. I count EVERYTHING, too. I don't use artificial sweeteners, so my drinks have been reduced to coffee, hot tea, water, and the (very) occasional tiny glass of juice... So I am counting the honey, agave, or raw sugar I use in my coffee or tea... I have also gone through all my favorite snacks and found the ones that have the lowest carb count and include protein, and those are the ones I keep handy for a quick "something." I've also been loading up on protein whenever I'm hungry - nuts are great! So is cottage cheese.
I've also been doing a lot of baking... Because it's fall, and I love to bake. And have been experimenting with lower-carb flours (coconut, oat, almond, etc.)... Cakes, muffins, everything. And I have a little of everything, but again, I count every carb that goes into them (as much as possible - I will always round up), and then divide that amount by the servings...
Good luck! It's been a great experience for me so far, and I hope yours is, too.
Oh, and I forgot to add - I have little self-control when it comes to carbs, which is WHY I went with lower carbs rather than cold turkey. My hubby has gone cold turkey three times in the last five months, and has lost control every time, on top of gaining back all the weight he's lost each time. I'm not interested in that...  |
