Yeah I don't think the weight loss thread really gets the fact that it's almost impossible to run less than 30g of carbs in a day as a diabetic. I pretty much always need to eat something before or after a workout (sometimes I can mess with my basal on my pump enough to stay pretty stable, but ultimately end up going low).
As for food I tried changing my whole diet about six or seven months ago. I never eat breakfast, lunch consists of low carb wraps, some kind of vegetable, fruit (strawberries, plums), Greek yogurt, and string cheese. Dinner is some kind of meat (chicken, steak, burger no bun) with some kind of vegetable, piece of toast, milk, salad, cottage cheese. And then if I have snacks I try and stick to nuts, more fruit, frozen yogurt (the one shitty thing I still buy), etc.
But by no means am I 100% to that as I'll be the first to admit I'm lazy when it comes to making food and I'll go out and buy a meal fairly regularly. I wanted to at least change from my old shit diet, and manage to stick to it about 70% in a week. Ultimately by doing so it ended up clearing up a lot of my intestine problems (had surgery on my colon in high school) and ended up dropping from my peak of 198 pounds to where I am now at 178 (I'm 6'2 for reference). But now I need to start moving towards more weight training which is what I'd like to start attempting to do now...
I've always had pretty good control of my diabetes though, pretty much averaged around 7.0 whole life, with end of college and to where I am now at about 6.5.
