I do not low carb, (although that will very much depend on your definition!)
I use the glycemic index to guide my choice of the foods I eat.. Like Sarah, as a type 1 , I use insulin so you must take that into account. I am able to maintain a healthy weight and good glucose control. I would add that I also consider exercise to be very important in my diabetes management.
In contrast to Sarah, I eat lots of salads (at least once, often twice a day) .Personally, my diet includes veg, salads , some fruit and dairy. A significant amount of the carbs I eat come from these types of foods.
Starches include small waxy potatoes, basmati rice, wild rice, quinoa ,pulses, oatmeal and seeded multi grain/nut breads in measured portions. These starches tend to be lower on the glycemic index. I tend to avoid foods that are higher on the index such as mashed potatoes, fluffy white rice and most white bread.
A typical plate for me will be at least half covered with veggies/salad, about a quarter, meat /fish , the rest starches (depends bit on weight ) I would for a main meal also include some fruit/berries, perhaps with a plain yoghurt . Sometimes, especially for lunch, I might have cheese as the dairy/protein combined. Salads /veg are often dressed with olive oil/vinegar. (vinegar helps reduce the GI of a meal)
The GI guides you to foods that will have lesser effects on glucose levels but as you will read on here, using a meter before and after meals will help you to determine what is right for you (and of cause we eat meals not individual foods so the content of the whole meal is important).
Some of the earlier posters on this thread say what they do, it's worth checking back. I know that there are also other T2s that also make use of the Glycemic index .
You will find a wealth of info about the GI here:http://www.glycemicindex.com/about.php
If you click on GI Newsletter and then 'Success stories' on the sidebar you will find several pages of accounts; click on older posts at the bottom of each page for more as there are a mixture of stories and some will have less relevance. There some great ones from people with T2 .
