lafonda, I'm not diabetic but I'm also overweight and was diagnosed with insulin resistance in 2011 (my levels have since returned to normal thankfully)
Do you know anything about glycaemic index? It's a numeric value which basically indicates how rapidly a food is broken down in the body to glucose. High-GI foods are processed quickly and lead to a quick 'hit' of blood sugar; low-GI foods are broken down more slowly and lead to a gradual increase in blood sugar levels. There's an inexpensive book called The Low GI Handbook which I found very helpful.
I basically tried to stay away from high-GI foods as much as possible, for example, white bread, white rice, potatoes. I decreased my consumption of these types of foods overall, and also replaced them with lower GI options instead, for example, grainy bread (look at labels for low GI), basmati rice, pumpkin or sweet potato.
Other general guidelines I followed were to avoid fizzy drink/juice/chocolate/lollies, avoid fried things (hot chips, etc.), eat lean meat (grilled/baked with minimal oil) and low-fat dairy, eat lots of fresh fruit and vegetables, moderate consumption of grains like pasta, grainy bread, etc. (but in reasonable serving sizes)
I'm at work so can't write much more, but hope that helps a little. A dietician or diabetic educator will be able to give you a detailed meal plan
ETA - I was also told that exercise is incredibly important for increasing insulin sensitivity. My GP said 30-60 minutes of cardio as many days of the week as possible (I aimed for at least 3 days, preferably 5). He said no need to go hell for leather at the gym, even just a brisk walk would help a lot.
