Wow, bringing your FBS down to the 80's from being pre-diabetic is quite impressive! What is the biggest thing you have done that made the huge impact (beside combining carbs with meat, etc)? I am all ears.
In general, I've reduced my carb intake across the board. Three easy changes that I think really made a difference for me:
1 - I used to eat a lot of rice, and I substitute it now with boiled barley. At first it was difficult, as barley has a very distinct flavor, but over time I grew to really like it, and now is almost a painless diet and nutrition improvement. For certain dishes, I miss white rice, but overall, I actually prefer the barley. Barley can take a while to prepare, so I make a big batch and freeze in individual portions. A couple minutes in the microwave and it's ready to go.
2 - I also used to eat lots of potatoes, and I substitute that with sweet potatoes. Sweet potatoes are not as GL friendly as barley is, but it is very GI friendly and much more nutritious. The only problem with sweet potatoes is that most people cook it way too long, basically converting the sweet potato into a candy bar (from a blood sugar perspective). I bake them no more than 35mins in the oven, and eat in place of regular potatoes. The more raw you can handle it, the better.
3 - The last major carb change was breakfast, which used to be almost always cereal (talk about a carb bomb). Now I have oatmeal most mornings - unsweetened, almost always with a piece of bacon or sausage. Don't go with the usual instant oatmeal (which has all kinds of added sugar and is too processed to have a good GI effect), go with steel cut or Coaches Oats which is similar but much easier to prepare. Alternatively, I sometimes have low-carb yogurt with a piece of fruit. Most yogurts are actually very high carb, but if you look around, you can find some very low carb (almost always NOT low fat) yogurts.
Other than that, it's the usual stuff, less dessert, less bread, less pasta, more fruits/veg, eating more frequently, etc. Most of this has been more difficult than the barley/sweet potato/breakfast changes (esp. the less dessert part), but I've gotten into a routine that, at least for the time being, seems to be working without too much effort...
